Mitsubishi Heavy Industries Central Air Conditioner Advantage Introduction【Detailed】 To be honest for 3 years Which is more cost-effective, ordinary air conditioner or central air conditioner Too many families think wrong What is the reason why Mitsubishi air conditioner does not startThe role of refrigeration compressors, what is the role of refrigeration and air conditioning compressors?
We know whether it’s a freezer or a refrigerator
All need a powerful compressor, So that the freezer can run normally.
The compressor is the core component of the refrigerator, which is equivalent to the human heart. The refrigerator uses advanced technology and excellent quality compressors, which will extend the service life of the refrigerator, improve the refrigeration effect of the refrigerator, and reduce the energy consumption and noise of the product.
The main function of the compressor is the electric motor as power,
Drive the compressor to rotate,
Makes the pushing piston reciprocate in the cylinder,
So as to promote the flow of refrigerant in the system,
The working process of the compressor is
Inhalation, compression, exhaust, expansion cycle process. The function of refrigeration compressor is: 1) Absorb refrigerant vapor from the evaporator to ensure a certain evaporation pressure in the evaporator.
2) Increase the pressure and compress the low-pressure and low-temperature refrigerant vapor into high-pressure and high-temperature superheated vapor to create conditions for condensation at a higher temperature (such as the temperature of about 35℃ in summer).
3) Transport and promote the flow of refrigerant in the system to complete the refrigeration cycle.
In air conditioning and refrigeration systems, the compressor plays the role of compressing and delivering refrigerant gas. The expansion valve plays the role of throttle and pressure reduction, and at the same time regulates the flow of refrigerant liquid into the evaporator, which is the dividing line between high and low pressure of the system. The evaporator is a device that outputs cold air, in which the refrigerant absorbs the heat of the cooled air and cools the air. The condenser is a device that releases heat. The heat absorbed in the evaporator and the heat converted by the work consumed by the compressor are emitted from the condenser together and taken away by the cooling air. Air-conditioning compressor is one of the main components of automobile air-conditioning system. It is the conversion device of low-pressure and high-pressure, low-temperature and high-temperature in the refrigeration system. The function of the compressor is to make the inlet of the compressor in a low-pressure state, so that the evaporator carries the latent heat (including the heat absorbed in the vehicle interior) of the refrigerant out of the evaporator. This low-pressure state allows the refrigerant to enter the evaporator. Compresses low-pressure gaseous refrigerant into high-pressure gaseous refrigerant. The two functions of the compressor only enter the evaporator. Compresses low-pressure gaseous refrigerant into high-pressure gaseous refrigerant. As long as one of these two functions of the compressor fails, the refrigerant in the air conditioning system cannot be circulated, and the air conditioning system will work poorly or fail to cool.
When the compressor of the air conditioning system is working, the suction valve sucks the refrigerant, and after compression, it is discharged from the discharge valve. Compressors used in automotive refrigeration systems can be divided into two categories: reciprocating piston and rotary according to their movement forms. Compressors for automotive refrigeration systems can be divided into fixed displacement and variable displacement according to whether their working capacity changes during operation. formula. The variable displacement compressor can automatically change the displacement according to the cooling load of the air conditioning system, making the operation of the air conditioning system more economical. At present, various swash plate and wobble plate compressors are widely used. In recent years, small and medium-sized cars have mostly used swash plate and rotary compressors, and few crankshaft connecting rod compressors have been used, while large buses still mainly use crankshaft connecting rod compressors.
The structure of the crankshaft connecting rod compressor is similar to that of the engine. Generally, the double-cylinder structure is adopted. The crankshaft rotates, driving the connecting rod to make the piston reciprocate, sucking and compressing gas. The cylinder body above the piston is equipped with an inlet and exhaust valve assembly, and a shaft seal is installed between the crankshaft and the housing to prevent refrigerant leakage. In order to ensure the normal movement of components, the crankcase is filled with a prescribed amount of compressor lubricant and oil supply facilities. The swash plate compressor is also called a swash plate compressor, which is an axial reciprocating piston compressor. At present, it is the most widely used in automobile air-conditioning compressors.
The swash plate compressors are used in the air conditioning systems of cars commonly used in China, such as Audi, Jetta and Fukang. The end position of the piston at the front end is the end of exhaust, and the other end of the piston is at the end of inhalation. When the main shaft drives the swash plate to rotate, the swash plate drives the piston to move axially. The piston moves in the axial direction in the front and rear cylinders at the same time, which is equal to the two pistons moving in both directions. The swash plate rotates once, and the front and rear cylinders complete one cycle, which is equivalent to the work of two cylinders.
The wobble plate compressor is also called the wobble plate type (also known as unidirectional swash plate type) compressor, which is an axial piston compressor with a reciprocating unidirectional piston structure. It is the same type as the swash plate type, and it is the most widely used model in automobile air conditioners. The variable displacement air conditioner compressor adopts a constantly meshed transmission mode. The transmission pulley is provided with a rubber part. The rubber part not only plays the role of transmission and vibration reduction, but when the air conditioner compressor is overloaded or locked, the rubber part is Cut off to avoid serious mechanical failure.
