R32应用于家用柜式空调机的可行性分析

Feasibility analysis of R32 applied to household cabinet air conditioner

理论分析R22和R32制冷剂在家用柜式空调机额定制冷工况下的性能参数,并进行相应的测试。测试结果表明:在额定制冷工况下,R32制冷剂排气压力是R22的1.74倍,排气温度比R22高14.3℃,能效低于R22,但R32机组在制冷剂和两器成本方面优势明显。

The performance parameters of R22 and R32 refrigerants applied to household cabinet air conditioner under the rated cooling condition are analyzed theoretically,and the corresponding tests are carried out.The test results show that under the rated cooling condition,the exhaust pressure of R32 refrigerant is 1.74 times that of R22,the exhaust temperature is higher than that of R22 by 14.3℃,and the energy efficiency is lower than that of R22,while R32 unit has evident superiority at the costs of refrigerant,evaporator and condenser.
