Study on the Dynamic Distributed Properties of Tube-Band Evaporator in Auto-Air-Conditioning

Based on thermal mass equivalence and pressure equivalence,this paper establishes a two-dimensional dynamic distributed model applied in the evaporator of the auto-air-conditioning system. The characteristics of mass transfer and heat transfer have been analyzed both inside and outside the tube;program calculation and experimental verification have been conducted on the model. The results show that the model is reliable and can be used to predict the evaporator's properties precisely,and they also provide reliable proof for further optimal design of this type evaporator.
