RESEARCH AND APPLICATION OF THE MINI-TUBE HEAT EXCHANGER IN ROOM AIR CONDITIONER

摘要：

It’s a hot research topic that how to improve heat transfer efficiency and reduce material cost in air conditioner industry. The main trend to solve the key issues is miniaturizing the outer diameter of precision inner groove copper tube used in heat exchangers. The situation of the mini-tube heat exchanger used in room air conditioner, which playing an important role in heat transfer enhancement, reducing cost and meeting the demand of new refrigerant of higher working pressure, is presented in this paper. The mini-tube heat exchanger has higher efficiency, which has been confirmed by experiments and application of Φ5 inner groove copper tube heat exchangers in window air conditioner and split-type one. Furthermore, some advice about the application of mini-tube heat exchangers was presented in the end of this paper.
