The characteristics of the heat transfer performance and pressure drop in 1 tank laminated evaporator which is an essential element of automobile air conditioner have been investigated experimentally. Five kinds of parameters which is affected by both sides of air and refrigerant are air mass flow rates, air temperature and humidity just in front of the evaporator, super heated temperature and evaporating pressure. It is confirmed that the heat transfer performance is governed by the key parameters of air mass flow rates, air temperature and humidity, but on the other pressure drop plays a decisive role about the function of gaseous Reynolds number in refrigerant. Furthermore, the characteristics curves of heat transfer, latent heat and pressure drop have been obtained.<br/>
