管带式汽车空调器蒸发器传热和空气侧阻力特性的实验研究

The Experimental Study on Airside Heat Transfer and Pressure Drop Factors of Evaporator in Autoair-conditioning System

给出了管带式蒸发器在常用雷诺数范围内空气侧的传热和阻力准则方程式,对析湿的影响进行了深入的研究,为该型蒸发器的设计和改进提供了依据。

The heat transfer and pressure drop characteristics of hand-tube evaporator,mostly used in car-air-conditioning system, have been investigated in detail through experiment. And the criterion correlations of heat transfer and pressure drop in the normal range of Renold number are presented. Special attention are payed to the humidity factors in this study. The correlations mentioned above can be used in the design and improvement of this kind of evaporators, also can be used in the thermal evaluation of car-air-conditioning system.
