HLD-40b高温空调混合制冷剂替代研究
Research on New Refrigerant Mixtures as Replacement in HLD-40b High Temperature Air Condtioner
摘要
Abstract
Aiming at the need of air conditioning in high humidity and high temperature environmental conditions, mixture of R22 and R142b is used to replace R12 in HLD -40b high temperature air-conditioner. All results have been verified by experiments. The refrigerating capacity and coefficient of performance (COP) of mixture are both basically equal with those of R12 under standard condition and 10.5% higher under T3 condition while the discharge pressure of mixture is 1.6MPa and discharge temperature only 90℃. From T3 condition to 60℃ condition, the refrigerating capacity decreases less than 10%. The performance is obviously improved in high temperature conditions. The refrigerating capacity under 60℃ condition is 4024W and the discharge pressure and temperature is 2.2MPa and 109℃ respectively. The stability of the device improves a lot. The research shows that mixture of high and middle temperature refrigerants can improve the stability and be used in various conditions.关键词
