Abstract

Experimental research of the plate-fin heat exchanger as an evaporator in a room air-conditioner with R22 was carried out according to the characteristics and requirement of a room air-conditioner. The research emphasizes particularly on the heat transfer and pressure drop characteristics of the heat exchanger, and the comparison with the common heat exchanger. The experimental results show that the heat exchange performance of the plate- fin heat exchanger used in a room air-conditioner is 2 to 3 times higher than that of the conventional one. The research and analysis of the plate-fin heat exchanger are needed for the optimum design of the conventional heat exchanger in a room air-conditioner.
