TECHNOLOGICAL TREND IN INNER GROOVED TUBE FOR ROOM AIR CONDITIONER

摘要

The technological trend of a high efficiency heat transfer tube for a room air conditioner is reviewed in this paper. An inner grooved tube widely used as the high efficiency heat transfer tube is aided by various high level technologies used for manufacturing and optimization, and its performance has been steadily improved year by year. It is suggested that the development of the inner grooved tube has been highly effective for improving the heat exchanger performance that is now required.
