Research on performance improvement of R32 refrigerant air conditioning based on outdoor unit flow path design
Compared with R22 refrigerant and R410A refrigerant used in traditional household air conditioners,R32 refrigerant is environmentally friendly,and R32 refriger-ant has better refrigeration performance than R410A,which contributes to the miniaturi-zation of system design.Due to the large refrigerating capacity per unit volume of R32 re-frigerant,R32 system has higher requirements for the flow design of condenser.In this paper,the flow path of R32 refrigerant air conditioning condenser is designed and opti-mized by the method of system simulation and experimental test,and the performance of refrigeration and heating is optimized by the variable shunting design.
