本文在对比分析风冷和蒸发式冷却方式的优缺点后,从房间空调器冷凝水应用这个角度,分析正在使用的和将来可能替代使用的五种不同工质:R22、R32、R410A、R134a、R290,其应用冷凝水对能效比的影响。经理论计算比较,房间空调器应用冷凝水能效比提高,最大达17.81%,为工质R410A;最小为12.87%,为工质R32;能效比平均提高15%,节能效果比较明显。因此冷凝水利用技术对工质为R410A的房间空调器更值得推广。
After comparing the advantages and disadvantages of air-cooled and evaporative cooling methods, this paper analyzes the five different refrigerants that are being used and may be replaced in the future by considering the application of condensate water in room air conditioners: R22, R32, R410A, R134a, R290, which uses the effect of condensate on energy efficiency. The theoretical calculation and comparison, room air conditioner application of condensate water energy efficiency ratio increased up to 17.81%, for the working fluid R410A; minimum of 12.87% for the refrigerant R32; energy efficiency than the average increase of 15%, energy-saving effect is more obvious. Therefore, the use of condensate water technology for refrigerant R410A room air conditioner more worthy of promotion.
