Two-stage turbocharging provides this engine with exceptional power, fuel efficiency, and reduced emissions, making it an ideal choice for industries that prioritize both performance and environmental responsibility. In this article, we’ll dive into the working principle of two-stage turbocharging on the MAN 18V48/60TS, detailing how this technology boosts air pressure, enhances combustion, and optimizes overall engine performance.

Two-stage turbocharging working principle on MAN 18V48/60TS

Two-stage turbocharging on the MAN 18V48/60TS engine is a sophisticated process that improves engine efficiency by compressing intake air in two stages, resulting in higher pressure and optimized fuel-air mixture. Let’s explore each stage in detail and the benefits of this innovative system:

1. First Stage: Low-Pressure Turbocharging
   In the initial stage, ambient air is drawn into a low-pressure (LP) turbocharger, where it is compressed and its pressure increased. This first stage ensures a steady intake of air, creating the initial boost needed to enhance fuel combustion. By pre-compressing the air, the LP turbocharger reduces the workload of the second stage and prevents issues like turbo lag, ensuring a smooth and efficient operation.

2. Second Stage: High-Pressure Turbocharging
   After passing through the low-pressure stage, the compressed air is directed to a high-pressure (HP) turbocharger for further compression. This second stage significantly increases the air pressure and density, allowing a higher volume of oxygen to enter the engine’s combustion chamber. The result is a more complete and efficient combustion process, which in turn boosts the engine’s power output and reduces fuel consumption.

3. Intercooling Between Stages
   To optimize performance and prevent overheating, an intercooler is placed between the LP and HP turbochargers. This intercooler cools the compressed air between stages, increasing its density and enhancing the effectiveness of the high-pressure turbocharging stage. By delivering cooler, denser air to the combustion chamber, intercooling ensures a consistent and high level of engine performance while protecting internal components from excessive heat.

4. Benefits of Two-Stage Turbocharging on the MAN 18V48/60TS
   The two-stage turbocharging system on the MAN 18V48/60TS offers several key advantages:

   • Increased Power Output: With higher air pressure, the engine can burn more fuel in each cycle, generating more power for demanding applications.
   • Enhanced Fuel Efficiency: By enabling more complete combustion, two-stage turbocharging reduces fuel consumption, making it cost-effective and environmentally friendly.
   • Lower Emissions: With improved combustion efficiency, the engine emits lower levels of pollutants, helping to meet stringent emission regulations.
   • Improved Load Response: The system’s design allows the engine to respond quickly to load changes, making it suitable for both steady and variable load applications.

13 things you need to keep in mind when using air conditioner

 

Air conditioners are commonly used in many households, but not everyone knows how to use them properly. Here are a few things to avoid when using air conditioners to increase the life of the machine, save energy and protect the health of your family.

1. Avoid choosing an air conditioner with a capacity lower than your needs

To cool a space of about 1 square meter, the average capacity of an air conditioner will be around 600 BTU/h. If you choose a machine with a capacity that is just enough or smaller, the air conditioner will run continuously and consume a lot of electricity, causing the machine to heat up due to lack of rest time, affecting the durability of the air conditioner.

Therefore, you should choose an air conditioner with a capacity slightly higher than your needs. When the required cooling level is reached, the air conditioner will automatically turn off, helping to prolong its durability.

2. Avoid using a generator to run an air conditioner

The generator's electrical frequency may differ from the input frequency of the air conditioner, causing the air conditioner to not operate. In addition, the generator's voltage is sometimes unstable, which can cause a short circuit or burn the compressor and circuit board inside the air conditioner.

3. Avoid installing air conditioners in high temperature locations

Many people believe that installing air conditioners in high temperature locations will help reduce the temperature quickly and create a cool atmosphere for the room. In fact, this concept is wrong because installing air conditioners in high temperature locations will cause the compressor to operate overloaded and consume more electricity than usual.

Therefore, you should install the machine in cool, airy locations and in the center of the room. This way, the temperature in the room can decrease quickly and then gradually cool down the areas with a lot of heat.

4. Avoid installing the air conditioner directly on the bed

The location of the air conditioner in the bedroom is also very important, because it directly affects the health of the whole family. If the cold air blows directly on the body for a long time, you will easily catch a cold and respiratory diseases.

Choose an installation location where the wind direction can blow across the entire room, without directly affecting you and your family. The most ideal location for installing the air conditioner is usually above, to the left or to the right of the entrance door.

5. Avoid turning on the air conditioner 24/24

The hot summer makes many people have the habit of turning on the air conditioner 24/24. This not only wastes electricity but also harms your health. You should turn off the air conditioner when it is not needed. If the weather is cool, you can use an electric fan instead and let the air conditioner rest. When sleeping, the body can withstand higher temperatures than when awake, so you can turn off the air conditioner at night.

6. Avoid turning the air conditioner on and off continuously

Some people often turn off the air conditioner when it is cold enough, then turn it back on when the room temperature increases because they think this will save electricity. But in fact, this causes the compressor and fan motor to restart many times, consuming a large amount of electricity, increasing the electricity bill and causing the air conditioner to break down faster. Moreover, the constant change in ambient temperature also has a negative impact on health, especially for the elderly and children.

To save electricity for your family, you should choose air conditioners with a capacity suitable for your family's needs as well as air conditioners equipped with energy-saving technology such as Inverter technology.

7. Avoid increasing and decreasing the air conditioner temperature continuously

Many people have the habit of increasing and decreasing the temperature continuously to adjust the room temperature. In fact, adjusting too much will disrupt the normal operation of the machine. However, new air conditioners today all have temperature sensors to maintain a stable temperature, not too hot or too cold. Therefore, it is not necessary to manually adjust, which wastes electricity and reduces the durability of the air conditioner.

8. Avoid turning on the air conditioner at low temperatures

When it's hot, many people want the room to cool down quickly, so they turn on the air conditioner at a very low temperature. This causes the room temperature to drop suddenly, and the body is also at risk of heat shock, causing dizziness and fatigue.

In addition, setting the temperature too low causes the compressor to operate at a higher capacity, causing the machine to break down quickly and waste electricity. You should adjust the appropriate temperature during the day to about 24 - 25 degrees Celsius and at night from 25 - 27 degrees Celsius to avoid affecting your health. In addition, you can refer to air conditioners with fast cooling technology to meet the cooling needs of the whole family.

9. Avoid closing the door when using the air conditioner

You have a habit of closing the door when turning on the air conditioner so that the cold air does not escape, causing a waste of electricity. However, when continuously using the air conditioner for a small room, you may feel tired and heavy due to lack of oxygen because the air in the closed room and the outside cannot exchange with each other.

Therefore, the best way is to create a very small gap for air circulation and choose a new generation air conditioner to have additional air filtering and antibacterial functions, helping the room to be airy as if it were breathing.

10. Avoid not maintaining and servicing the air conditioner regularly

The air conditioner helps bring air into the house and suck hot air carrying dust out. Therefore, after a period of use, if the air filter is not cleaned and maintained regularly, family members may suffer from respiratory diseases. Therefore, regularly clean, sanitize and maintain the air conditioner to ensure the best operation, ensure air quality and save electricity.

11. Avoid too much temperature difference between inside and outside

With the need to cool quickly, most people when using air conditioners set the temperature to the lowest level of 16 degrees Celsius. However, if the temperature in the room is too different from the outside temperature, it will easily cause you to get heat shock.

Therefore, you should adjust the room temperature to be about 7 degrees Celsius different from the outside so that your body is not affected by the large temperature difference. For example, if the outside temperature is 31 degrees Celsius, you should adjust the temperature to about 24 degrees Celsius.

12. Avoid lying on your back when sleeping in an air-conditioned room

Lying on your back for too long will dry out your nose and throat, causing many health problems, especially respiratory problems because we breathe cold air directly. Therefore, you should not lie on your back in an air-conditioned room for too long. At the same time, adjust the temperature appropriately and avoid placing the air conditioner opposite your bed.

13. Avoid entering an air-conditioned room immediately after coming back from the sun

After coming back from the sun or exercising, your body is at a high temperature and sweats a lot. Therefore, if you enter an air-conditioned room immediately, your body will not be able to adapt in time, leading to heat shock, colds, headaches, etc., which is more dangerous than stroke because the blood vessels suddenly constrict.

Therefore, when you come back from the sun, you should wait in a cool area for your body to recover to normal before entering an air-conditioned room. In addition, you should also drink enough water and wear warm enough clothes to be comfortable with the cold room temperature.

What is the right temperature to set the air conditioner?

 

Depending on the weather conditions, choosing the right air conditioner temperature will help you feel more comfortable and relaxed. Check out the article below to find out what the highest and lowest temperatures of the air conditioner are, and then adjust accordingly!

1. What is the lowest and highest temperature of the air conditioner?

Lowest temperature

The cooling capacity of each air conditioner line is different, depending on the capacity, brand and integrated cooling technology. Normally, the lowest temperature of air conditioner lines on the market is 16 - 18 degrees Celsius

Maximum temperature

The maximum temperature of air conditioners ranges from 30 - 32 degrees Celsius. However, you should not use the maximum temperature limit so that the compressor can operate stably and ensure that your body feels comfortable and pleasant.

2. Choosing the right air conditioner temperature

On hot days, people often tend to set the air conditioner temperature too low, below 20 degrees Celsius to cool quickly. However, you should adjust the room temperature to be about 5 degrees Celsius different from the outside to avoid negative effects on your health.

In addition, if you have just come back from outside, you should not set the air conditioner temperature to the lowest level. Because this not only wastes electricity when the air conditioner has to operate at full capacity to cool at the highest level, but also has negative effects on health such as "heat shock".

Experts recommend setting the air conditioner at 25 - 28 degrees Celsius is best for our health, especially for rooms with infants and young children, it should be set at 28 - 30 degrees Celsius.

3. Why does the air conditioner not reach the set temperature?

When using the air conditioner, sometimes your home appliance does not reach the set temperature. The cause of this situation may be due to:

The evaporator temperature sensor is broken.

The air conditioner has been used for a long time without being cleaned or maintained, causing the evaporator to become dusty and the cool air cannot escape. Therefore, the device does not reach the desired temperature.

The cooling mode is not set correctly.

The air conditioner is low on gas or has a gas leak, causing the cooling capacity to weaken.

The compressor of the device is damaged.

4. Some notes to help the air conditioner maintain the standard temperature

In addition, there are some other small tips that you should note:

You should choose the night sleep mode of the air conditioner so that the room temperature gradually increases to the desired level. This mode helps us to have a deep sleep, at the same time, saving electricity effectively.

You should arrange the location of the air conditioner in the room so that the cold air does not blow directly on people, especially children to avoid health problems such as pneumonia, cough, ...

You should use a ventilation fan when turning on the air conditioner and do not let the room get too humid.

Do not use the air conditioner continuously, or turn it on/off suddenly for a long time.

Do not use the air conditioner when you have a fever or sweat. This will cause a cold and can make the illness worse.

Always clean the room and clean the air conditioner to reduce bacteria, mold, and dirt in the room.

Check the gas line, charge the gas for the air conditioner.

Check the fan and maintain the condenser.

Check the compressor performance and operating load.

Remove any obstructions to the cooling air flow.

3. The air conditioner is too cold

The cause of the air conditioner being too cold may be due to the temperature controller of the machine being damaged, or the temperature being set too low compared to the usage needs.

How to fix:

Check the circuit of the temperature controller and the wire.

Adjust the temperature accordingly.

4. Compressor noise

The phenomenon of compressor noise often occurs in outdoor condensers. You can easily recognize it by turning on the air conditioner, even though you are in the room, you can still hear the rumbling sound from outside.

The cause of this phenomenon may be due to loose bolts or screws, or damaged parts inside the compressor that make the machine unstable. In addition, excess gas or strong friction between pipes with each other or with the machine shell can also cause noise during operation.

How to fix:

Fix the pipes to prevent them from colliding with each other.

Check if the place where the condenser is placed is flat or not, the compressor shell is dented and causes collision with the internal parts or not. At the same time, check the bolts at the bottom of the machine to see if they are loose or not. Then, reposition the machine to stabilize and tighten the loose bolts.

Discharge the excess gas outside with a hexagon valve. The discharge location is right at the cone end of the condenser.

Replace the new compressor. Before replacing, you need to check the code, brand and capacity to choose the right one.

5. The machine runs continuously but is not cold

Sometimes you will find that the air conditioner is still running continuously but is not cooling effectively. Some causes that can cause this situation are:

Lack of gas due to a leak or a clogged gas pipe.

The air filter and evaporator are dirty, preventing cold air from being blown out.

The condenser is dirty.

Insufficient air passing through the evaporator.

The cooling air is not circulating.

The compressor is not working effectively.

The load is too heavy, causing insufficient power for the machine to operate.

How to fix:

Check the gas system. Remove gas, vacuum and recharge gas if necessary.

Clean the air filter system and evaporator.

Maintain the condenser and radiator system.

Check and remove objects that obstruct the cooling air flow.

Check the load and voltage of the electrical current. If the load is not enough, you should turn off unused electrical devices, or use a voltage stabilizer to ensure stable electrical current.

6. The air conditioner is not cold while there is still air blowing out from the body of the machine

If you feel that the air conditioner is not cold or warms the air even though there is still air blowing out from the body of the machine, it may be due to the following reasons:

The set temperature is higher than the cooling demand.

The room is not sealed, leading to cold air loss to the outside.

The air filter and evaporator are covered with dust.

The room is too large for the capacity of the machine.

How to fix:

Check the temperature setting to see if it is suitable for the cooling needs? Reset the temperature and cooling mode for the air conditioner to achieve the desired cooling effect.

Check if the air filter is working properly, cleaning the air filter will help the air conditioner work well and cool more stably.

Check and close the main door, windows of your house or office if they are open.

Clear the air inlet and outlet ducts in the indoor and outdoor units, then wait about 3 minutes and restart the air conditioner to allow stable air circulation and better air exchange.

The air conditioner may not cool while in compressor protection mode for 3 minutes, so please wait until this mode is completed.

Check if there are any high-heat appliances such as electric grills or hot water basins in the room, the heat emitted will also affect the coolness in the room.

7. Unpleasant odor from the air conditioner

During use, your air conditioner has a foul odor and you smell odors such as:

The pungent smell of gas: Due to the evaporator leaking gas, if the gas concentration is high, it will be dangerous and toxic to the user's health, easily making you unconscious and dizzy.

Bad smell from the toilet: The cause is due to the evaporator drain pipe being directly connected to the toilet drain system.

Moldy smell: Due to long-term use without cleaning, the air conditioner has mold inside and emits a foul odor.

How to fix:

If the air conditioner smells of gas, you need to turn it off immediately, open the room door, use a fan to quickly remove the odor and check the gas pipe again.

If the air conditioner smells of the toilet, you should contact a technician to repair the evaporator drain pipe.

If the air conditioner smells of mold, you just need to clean the evaporator.

8. The machine runs and stops continuously

In some cases, the air conditioner runs for a while and then turns off, then this process repeats continuously, not only wasting electricity but also affecting the experience of using the product.

Some causes of this phenomenon:

Lack or excess of gas causes the machine to operate unstably.

The gas pipe is obstructed and clogged.

The contactor coil of the compressor is damaged.

The condenser is dirty and clogged.

The expansion valve or capillary tube is clogged. Or the sensor bulb of the expansion valve is leaking.

Low voltage is not enough for the machine to operate.

How to fix:

Recharge the gas if it is lacking or drain the gas if it is too much.

Remove the parts that obstruct the pipeline.

Periodically clean the air conditioner. At the same time, maintain the condenser - evaporator and important connection parts.

Replace the expansion valve and capillary tube if necessary.

Ensure the operating voltage of the air conditioner is correct according to the rating on the machine. Use a voltage stabilizer if necessary.

9. The condenser fan does not run

The condenser fan has the function of dissipating heat from the condenser by sucking in outside air and blowing it into the condenser, helping the heat exchange process of the condenser to take place better. The faster the condenser heat dissipation process, the better the cooling efficiency of the air conditioner.

The following reasons will cause the condenser fan to not work, affecting the cooling capacity of the air conditioner:

Due to the mechanical part: After a long time of use, the condenser fan can wear out the bearing, the shaft is tight, the grease is dry, ... leading to muscle stiffness, making the fan unable to rotate. You can easily recognize it by using your hand to turn the fan blade. If it feels heavy when rotating, the fan stops when you let go of your hand, then the mechanical part is damaged, affecting the operation of the condenser.

Due to the electrical part: Broken wires, burned motors, burned capacitors, broken power cords are all electrical damages. The way to recognize it is to use an ammeter to measure the current running in the circuit.

In some air conditioner models, the power supply to the fan is controlled from the evaporator circuit board. Therefore, when the circuit board is faulty, the fan will also stop working.

In case the block is damaged, the gas stops cooling, leading to a system error, so the entire condenser stops working.

How to fix:

Check the capacitors, circuits, etc. yourself with an electric meter. Or you can contact the warranty staff to do a more general check and replace some damaged components if any.

10. The evaporator fan does not run

The evaporator fan has the effect of cooling the internal parts of the evaporator, while also preventing dust from sticking to the evaporator, helping the air circulate stably. The evaporator fan not running will cause no cold air to blow out from the air deflector, the air conditioner will not cool.

The reason why the evaporator fan does not run may be due to:

The fan motor is short-circuited or touches the shell, causing the air conditioner fan to wear out, causing muscle cramps.

The power cord to the fan is broken or the power cord is loose. The motor wire is burned, a wire in the motor is broken, etc. are also the reasons why the evaporator fan does not work.

The fan contactor coil is damaged.

The capacitor is short-circuited.

How to fix:

If the evaporator fan does not work due to long-term use, you should contact the warranty center to check and replace the components.

11. The machine is low on gas, out of gas

The gas inside the air conditioner is a chemical that does not decompose, so it will not normally be lost during the operation of the machine. In the case of a low on gas, out of gas, it only occurs due to a leak in the pipeline, a leaking valve, etc., or during a new installation, the technician does not check and refill the necessary gas.

To know if the air conditioner is low on gas or not, you should pay attention to the following phenomena:

The machine is not cold, not cold enough.

The small pipe valve of the condenser is covered with snow.

The operating current is lower than the rated current recorded on the machine.

The gas pressure sucked into the compressor is lower than the normal pressure (normal value is from 65 - 75 psi). The pressure on the high pressure side is also lower than normal.

In some air conditioners, the control board will automatically turn off after 5 - 10 minutes of operation and report an error on the condenser.

How to fix:

Contact the warranty center to check the pipeline system and refill the gas.

12. Block running and stopping continuously due to overload

The air conditioner block not running will also lead to the air conditioner not cooling. This can be due to the following reasons:

The compressor has no power supply: Due to the control board, open circuit or damaged contactor that cannot be closed.

Due to damaged capacitor, damaged condenser fan, poor operation of compressor motor.

Burned motor coil inside.

Lack or excess gas.

Low or unstable voltage.

How to fix:

In case of burned motor wire, damaged fan or other components, you need to replace them.

Fully charge the gas if it is lacking or drain the gas if it is excess.

Use a voltage stabilizer to ensure stable voltage.

13. The machine is leaking water in the evaporator

The air conditioner has the ability to continuously create condensation, the excess water will be drained out by plastic, rubber pipes or small electric pumps. If the machine is leaking water, dripping in the evaporator, it is due to the following reasons:

When installing the drain pipe without a slope, the water cannot drain out and remains in the trough. Over time, it leads to overflow in the trough and flows down the wall. If the wall is made of plaster, it will cause serious damage.

If you use the machine for a long time without cleaning, the drain hole at the cold side is clogged, causing overflow and water to leak.

How to fix:

To make the drain pipe slope and drain better, you need to readjust the pipe. For coolers with long pipes, the drain pipe should be placed in a certain position, not along the pipe.

Clean the machine

What is ISSC renewal?

The International Ship Security Certificate (ISSC) renewal is a mandatory process that takes place every five years to ensure that a ship remains compliant with the International Ship and Port Facility Security (ISPS) Code. The ISSC certifies that the ship’s security management system meets international standards and that the security measures outlined in the ship’s Ship Security Plan (SSP) are being effectively implemented.

Steps for ISSC Renewal:

1. Preparation for the Renewal Audit:

   • The Ship Security Officer (SSO), in collaboration with the Company Security Officer (CSO), ensures the Ship Security Plan (SSP) is up to date and fully implemented.
   • All crew members must be properly trained on security procedures, and security drills should be conducted regularly.
   • Security records, such as logs of drills, security incidents, access control, and any previous audits, should be in order and available for review.

2. Renewal Audit:

   • The renewal process involves an external audit by the ship’s flag state authority or a Recognized Security Organization (RSO) (such as a classification society).
   • During the audit, the auditor reviews the ship’s security procedures and the effectiveness of the SSP, verifying that:
     • The ship is maintaining appropriate security levels.
     • All security equipment, such as the Ship Security Alert System (SSAS) and surveillance systems, is fully functional.
     • Crew members understand their roles in the ship’s security procedures.
     • All documentation is up to date, including security incident reports, audit findings, and corrective actions.
   • A physical inspection of the ship's security measures (e.g., access control, restricted areas) is conducted to ensure compliance with the ISPS Code.

3. Correction of Non-Conformities:

   • If any non-conformities (deficiencies or violations of ISPS Code requirements) are found during the audit, they must be addressed within a specific timeframe.
   • Minor non-conformities: These are small issues that can typically be corrected without major operational disruptions.
   • Major non-conformities: These are more serious security deficiencies that must be corrected before the certificate can be reissued. In some cases, a follow-up audit may be required to verify that corrective actions have been completed.

4. Issuance of the Renewed ISSC:

   • After a successful audit, with any non-conformities resolved, a new ISSC is issued by the flag state or RSO.
   • The renewed ISSC is valid for another five years, subject to passing intermediate audits during the certificate’s validity period.

5. Intermediate Audit:

   • During the five-year validity period, an intermediate audit must be carried out between the second and third anniversary of the certificate's issuance.
   • This audit ensures that the ship’s security system continues to comply with the ISPS Code. If the intermediate audit is not completed in the specified timeframe, the ISSC may become invalid.

6. Consequences of Failing to Renew the ISSC:

   • If the ISSC renewal is not completed before the expiration date, the ship may face serious consequences, including:
     • Detention by Port State Control (PSC), resulting in operational delays.
     • Ineligibility to enter certain ports or regions that require a valid ISSC for access.
     • Potential impacts on insurance coverage or charter agreements.
     • Increased scrutiny or penalties from regulatory authorities.

Key Points in ISSC Renewal:

• The ISSC is renewed every five years after a successful external audit.
• The renewal audit checks the ship’s compliance with the ISPS Code and the effectiveness of its security management system.
• If non-conformities are found, they must be resolved before the certificate is reissued.
• An intermediate audit is required during the five-year period to ensure continued compliance.
• The renewed ISSC allows the ship to continue international operations without security-related restrictions.

In summary, ISSC renewal ensures that the ship maintains the highest security standards, safeguarding both the crew and the vessel while enabling it to operate globally
