Technical Expert Teach You How to Maintain Truck Refrigeration Unit

 

Refrigeration unit is an important part of the refrigerated truck, its refrigeration effect and performance directly affects the quality of the refrigerated truck, different refrigeration units also lead to different prices of refrigerated trucks. Here, Chengli professional and technical personnel for you to give the best daily maintenance methods of refrigeration machine. The main maintenance of the refrigeration unit is from the following three aspects:
        First, refuel the truck refrigeration unit.
        1. Connect one end of the refueling pipe to the refueling valve at the inlet of the compressor, slightly open the refueling valve, use the pressure in the system to discharge the air in the refueling pipe, and insert the other end into the oil drum.
        2. Appropriately close the system refrigerant supply valve, and adjust the suction low
The pressure alarm setting should be adjusted to avoid stopping due to low pressure.
        3. When the suction pressure is lower than the atmospheric pressure, open the refueling valve, the oil will automatically enter the compressor.
        Second, to refrigerate the refrigerator of the refrigerated truck refrigeration unit refrigerant replenishment.
        1. Connect one end of the fluorine tube with the system fluorine port, and the other end with the fluorine bottle, and drive out the air inside the tube through the fluorine hose.
        2. Open the valve of the fluorine bottle first, and then open the valve of the fluorine filling port after confirming there is no leakage.
        3. The R23 system should face upward, while the R404A system should face downward to ensure rapid fluoridation.
        4. the end of fluoride, should first close the valve of the fluorine bottle, and then close the valve of the fluoride port
        Third, the refrigerator to the refrigerator unit of the refrigerator air release.
        1. high-temperature systems should be carried out in the parking, low-temperature systems are best in operation
        2. the specific operation should be careful, the silk plug do not open too large, and do not move away from the scene
        3. Air operation should be carried out several times, not too much air can be released at one time, so as not to release too much refrigerant.
       Refrigerated trucks prices are also affected by the refrigerated car manufacturers, the same refrigerated car different manufacturers produce refrigerated car prices are not the same, the impact is relatively small, refrigerated car manufacturers are relatively large scale cost to low, the factory refrigerated car prices have an advantage. Refrigerated car prices are also manually affected by the size of the market demand, demand high prices which is also a law; reefer prices are also affected by national policies and industry standards for refrigerated vehicles

 



 

 

Working Principle and Application Technology of Truck Refrigeration Unit

 

 

 

 

       Refrigeration units of refrigerated trucks can be divided into two types of non-independent refrigeration units and independent refrigeration units. Non-independent refrigeration units are generally designed for vans and small and medium trucks for low and medium-temperature applications. The independent refrigeration unit, on the other hand, is mostly used in large refrigerated trucks and semi-trailer refrigerated trucks, which are equipped with a secondary engine.
      The refrigeration unit of the refrigerated truck is driven by the truck engine to run the compressor for cooling and defrosting. And according to the needs of users, the optional compressor is driven by an electric motor to run for cooling and defrosting (referred to as the power backup unit). The system consists of at least three separate components: condenser, evaporator, and compressor. The compressor is mounted on the truck engine and driven by it. Refrigeration hoses or pipes are used to connect the condenser, evaporator, compressor, and other components. The backup unit has an additional compressor and an electric motor and oil separator, etc., for power-driven operation. The engine compressor is driven by the engine via a belt. The power-driven compressor and the engine-driven compressor are connected in parallel. The power-driven compressor is driven by the motor belt. Both the refrigeration unit and the cab air conditioning compressor use the same refrigeration system circuit.
      A check valve separates the two compressors during operation. The operation of the compressors is controlled by a controller. The unit supplies power to the refrigerated truck compressor clutch during engine operation or to the starter motor, and to the compressor clutch during power-driven operation. The entire refrigeration system is protected by a pressure cut-off switch.
  Cleaning the refrigerated carriage helps to keep the carriage clean and stay out of odors. This should be well understood, refrigerated cars are somewhat similar to refrigerators, if you do not pay attention to cleaning, it is easy to have a strange smell. Refrigerated trucks are often loaded with different goods, especially fish, meat, etc., it is best to clean the carriage once after each delivery of goods.
  Another role is to prevent the refrigeration unit’s evaporator fan will be impurities inhaled into the evaporator coil, thus reducing the refrigeration effect of the refrigeration unit, which is one of the reasons why the refrigerated truck with a few years after we will feel that the refrigeration effect is not as good as the beginning.

 

 



How to Maintain A Refrigerated Truck

 

 

 

 

A refrigerated truck is a special vehicle installed with a refrigeration unit. There are some facts that must be paid attention to before driving to prevent some unnecessary trouble on the way.

 

  1. Make sure that fuel or gasoline supply is sufficient to keep the engine running at least to the next checkpoint. At the same time, remember that do not over-fuel.

 

  1. Check refrigerated truck coolant to see if the coolant amount is correct, the pointer should be in the white range. If the level point is within the red range, you need to add coolant to the  Usually the coolant is a mixture of glycol and water (different ratios are used according to the actual situation where the product is used), and should provide protection to -34°C without freezing. Note: Do not open the lid of the coolant tank when the coolant is hot.

 

  1. Reefer battery terminals must be solid and free from corrosion. The electrolyte should be at the full mark.

 

  1. The belt must run in good condition and be adjusted to the proper expansion and tightness. Span the central 13mm sag between the pulleys.

 

  1. Check all electrical connectors in the control line to ensure that they are securely fixed. Wires and terminals should be free of corrosion, burn cracks or water.

 

  1. The condenser and evaporator of the refrigeration unit should be clean and free of dirt. Also, Cargo should not block the evaporator air outlet, so as to keep the cold air circulation smoothly in the cargo

How to prolong the service time of your Reefer Units

 

Reefer truck as an important transport tool in the cold chain logistics industry, and the refrigeration unit is the heart of a refrigerated truck. The cost to change or repair a refrigeration unit is considerable. So how can we prolong the service time of a refrigeration unit and a refrigerated truck?

 

First, if the temperature of your cargo is too high or too low, please set the refrigeration unit to the necessary transport temperature, through a certain period of time the temperature of the goods down to or up to its necessary temperature. However, the fact is the opposite, not only the temperature of the goods do not come down (or up), but to damage or deteriorate the goods.

Refrigeration unit blowing cold air will make the temperature of the goods change, the goods will lose moisture, which will lead to changes in the quality of the goods, which will lead to a decline in the quality of the goods, shorten the storage period, and even the spoilage of goods.

 

Second, pre-cool the refrigerated truck.

Before loading, the carriage must first be pre-cooled or pre-heated for about 1.5 hours. Because the vehicle is parked in the open air, usually the temperature of the carriage is the temperature of the outside environment. Goods being put into the carriage, the carriage inside the ambient temperature will affect the temperature of the transported goods, thus leading to changes in the quality of the transported goods, so the carriage must be pre-cooled to the necessary temperature before loading.

 

Third, the insulation of the refrigerated truck

A refrigerated car is not cold storage, but many people think that the refrigeration unit on the refrigerated car is free to freeze or refrigerate the goods inside the cargo box. In fact, the refrigerated vehicle is used to maintain the temperature of the goods, rather than to reduce the temperature of the goods.

 

Fourth, the refrigeration unit must be closed when loading and unloading.

The refrigeration unit must be closed when loading and unloading, many people don’t close the door when loading and unloading, thinking that this can make the temperature of the goods rise more slowly, in fact, this is wrong.

If the refrigeration unit is on when the carriage door is opened, the fan of the evaporator of the refrigeration unit is working and will be cold air from the upper part of the carriage blowing out, and the lower part will be outside the hot air quickly sucked in, resulting in a rapid rise in the temperature of the carriage; if the machine is turned off and then loading and unloading goods, the fan will be in a stopped state, the airflow stops,  the wind pressure inside and outside the carriage is the same, the hot air outside.

 

Five, the placement of goods.

Cargo placement must be taken into account, the cold air circulation in the refrigerated carriage, the best goods can be stacked on the double-sided pallets, fresh goods pallets can not be wrapped in plastic film, the plastic film will block the circulation of cold air circulation to the goods, the best distance between the top of the carriage and the goods to stay more than 23cm.

The floor of the refrigerated truck generally has a groove that can be ventilated, but some do not, if not, use double-sided pallets to load the goods to ensure the flow of cold air at the bottom of the floor.

Cargo stacking can not be too high, not higher than the plane height of the air outlet. If the front of the air outlet is blocked by the goods or too close to the goods, it will not only affect the storage temperature of the goods, but also the normal work of the refrigeration unit, which will affect the cold air circulation in the carriage and lead to the freezing of the goods near the vent, while the temperature of the goods elsewhere may be too high.

And refrigeration units are generally with air induction defrost design, the goods are too close to the vent, near the vent ice, the unit will quickly enter the defrost state, the temperature rises, defrost immediately ended, repeated this action, and the temperature in the car does not come down.

When transporting vegetables and fruits, we should pay more attention to the fact that vegetables and fruits will produce breathing heat, and if the circulation of cold air is not good, the temperature in the central part of the carriage will rise, which will lead to problems with the quality of the goods. Also, the upper goods which are closer to the air outlet should be covered with a cover cloth to protect them from frostbite.

 

Sixth, the interior of the car environmental health

Cleaning refrigerated carriage has two roles, one is to maintain the internal environmental health of the carriage, to prevent strange smells inside the carriage. This should be well understood, refrigerated cars are somewhat similar to refrigerators, if you do not pay attention to cleaning, it is easy to have a strange smell. Refrigerated trucks are often loaded with different goods, especially fish, meat, etc., it is best to clean the carriage once after each delivery of goods.

Another role is to prevent the refrigeration unit’s evaporator fan will be impurities inhaled into the evaporator coil, thus reducing the refrigeration effect of the refrigeration unit, which is one of the reasons why the refrigerated truck with a few years after we will feel that the refrigeration effect is not as good as the beginning.
