Research on size optimization of key components of heat⁃recovering air conditioner

本文建立了热回收空调系统空调机的数学模型,分析了毛细管、蒸发器、冷凝器的关键尺寸对热回收空调系统空调机运行性能的影响规律。结果表明,增加毛细管长度,机组的制冷量和制冷系数会先增大后减少;适当增加蒸发器和冷凝器的换热面积,机组的制冷量和制冷系数会增加。本文的研究将有利于热回收空调机的推广及应用。

Mathematical model of air conditioner of heat⁃recovering conditioning system was established in this paper and the influence of capillary tube,evaporator,and condenser geometry on the operation performance of the air conditioner was analyzed.The results showed that the cooling capacity and the cooling coefficient of the air conditioner increased first and then decreased with the increase of the capillary length.Within a certain range,as the heat transfer area of evaporator and condenser increased,the cooling capacity and cooling coefficient of the air conditioner increased.This paper provided reference for the promotion and application of heat⁃recovering air conditioning system in air conditioning industry.
