摘要
针对带喷气冷却和不带喷气冷却的R32风冷单元式空调机进行实验研究。研究发现,虽然采用喷气冷却导致系统的冷凝压力较高且系统性能系数降低,但可以有效提高系统制冷量,降低压缩机的排气温度,有效提高系统的可靠性。
The experimental study is carried out on R32 air-cooled unitary air condi- tioner with vapor-injected and without vapor-injected. Experimental results show that although the condensing pressure of R32 air-cooled unitary air conditioner with vapor-injected is higher and the COP of it is lower compared with unitary air conditioner system without vapor-injected, the vapor-injected cooling method could increase the system＇s refrigeration capacity and decrease the compressor＇s discharge temperature which could increase the refrigeration system＇s reliability.
