摘　　要：提出一种在汽车空调应用中替代R134a的新型制冷剂HFO-1234yf/R134a/DME。利用数据库REFPROP 9.0,通过自行编制的软件对该制冷剂的热力学性能和循环性能进行理论分析,并在电量热器制冷剂循环性能测试装置上,对R134a和HFO-234yf/R134a/DME进行试验研究。理论与试验研究发现,新型制冷剂的制冷量比R134a略小,循环性能系数(COP)也略低,而排气温度比R134a低12℃左右。该新型制冷剂具有替代R134a的潜在可行性。A new type refrigerant HFO-1234yf/R134a/DME is proposed to substitute R134a in the automotive air-conditioning. Making use of the REFPROP 9. 0 database, thermodynamic calculation and cycle performance analysis are conducted through compiling program. Experimental study is conducted on the cycle performances of R134a and HFO-1234yf/R134a/DME by an electric calorimeter testing device. The theoretical and experimental results show that the cooling capacity and COP of this new type refrigerant are slightly lower than those of R134a, but the discharge temperature is reduced approximately by 12 ℃ compared with R134a. The new refrigerant is feasible to substitute R134a potentially.
