Operating principle of air conditioning reservoir
1、 General operating principle of reservoir
Storage and buffering functions
During the operation of the air conditioning system, the flow and state of the refrigerant will change. The accumulator can store excess refrigerant and act as a buffer. For example, in the refrigeration cycle, when the evaporator load is reduced, the evaporation capacity of the refrigerant decreases. At this time, the refrigerant returning from the evaporator may be more than the suction capacity of the compressor. The excess refrigerant can be temporarily stored in the reservoir to prevent a large amount of liquid refrigerant from returning to the compressor and causing liquid hammer, so as to protect the normal operation of the compressor.
Gas liquid separation function
In the air conditioning system, the refrigerant may exist in the state of gas-liquid mixture. The accumulator can separate the gas-liquid mixed refrigerant into it, so that the liquid refrigerant is deposited at the bottom of the accumulator, while the gaseous refrigerant is located at the top. This helps to ensure that only gaseous refrigerant enters the compressor, because if liquid refrigerant enters the compressor, it will cause damage to the compressor and affect the efficiency and life of the compressor.
2、 Influence of characteristics of small aluminum air conditioning reservoir on its working principle
Characteristics of aluminum materials
Portability: the aluminum material is relatively light, which is convenient for the overall layout and installation of the air conditioning system, making the installation position of the reservoir in the air conditioning system more flexible. This feature does not directly affect the working principle, but helps to optimize the design and manufacture of air conditioning systems.
Good thermal conductivity: aluminum has good thermal conductivity, which helps the refrigerant exchange heat with the external environment in the reservoir. For example, during the refrigeration process, if the external ambient temperature of the reservoir is low, the heat can be transferred out through the aluminum reservoir wall, which helps to further cool the liquid refrigerant and make it more stable in the reservoir.
