在分析比较 R290、R22、R410A 三种工质热力性能的基础上,对采用 R290工质的空调器提出了优化设计原则.优化设计原则主要针对压缩机、冷凝器、蒸发器、节流装置四大部件:R290空调器的压缩机应增加排量;R290空调器的冷凝器可采用小管径换热器;R290空调器的蒸发器可采用小管径换热器;R290空调器的毛细管应比R22空调器的长约39%,比R410A空调器的短约44%.在提出R290空调器优化设计原则的同时,本文对保证R290空调器安全性提出了建议.

The principle for optimal design for air conditioners with refrigerant R290 is proposed. The principle is based on the thermal performance analysis and comparison of the three refrigerants, which are R290, R22 and R410A. The principle includes the optimal design of compressor, condenser, evaporator and orifice set: the compressor discharge rate of R290 air conditioner should be bigger; the condenser of R290 air conditioner can adopt heat exchangers with smaller diameter tubes; the evaporator of R290 air conditioner can adopt heat exchangers with smaller diameter tubes;the capillary length of R290 air conditioner should be about 39%longer than that of R22 air conditioner, and should be about 44%shorter than that of R410A air conditioner. Meanwhile, the suggestion of how to guarantee the security of R290 air conditioner is also proposed in this paper.
