摘要

Air source heat pump (ASHP) with no cooling water system is more convenient than water-cooled chiller in installation, operation and maintenance, etc. It can serve for building both in summer and in winter without other heat source equipment such as boiler. China has a large territory. She crosses four climate zones. Four seasons can be distinguished easily around the middle and lower reaches of Yangtze River, where it's cold in winter and hot in summer. But in whiter, there is no extremely cold day. In this district, it needs cooling in summer and heating in winter. There are many factors in the choice of air-conditioning's cold and heat source. ASHP has become one of the most popular products for its merits. In the paper, the site tests have processed with air-source heat pump operation in some public buildings. And their energy performance has been analyzed. From the point of energy efficiency view, the prospect for the air-source heat pump's wide application is not so excited.
