SOME ASPECTS OF APPLICATION OF WATER-LOOP HEAT PUMP SYSTEMS IN CHINA


Water-loop heat pump systems have been developed and spread rapidly in China recently. But some
failing samples hindered the further promotions. The authors believe that some aspects need to be
especially concerned in the process of application under the specific conditions of China to achieve a
successful project. First, a detailed technical and financial analysis should be made to determine if the
water loop heat pump system is feasible to the project. Noise level is also a critical factor for a successful
application in China because Chinese people are more sensitive to noise than people in other countries.
Some noise control methods both for equipment manufacture, project installation and system design are
advised in this paper to meet the requirements of Chinese people. Some other viewpoints on how to apply
water-loop heat pump systems in China are also discussed on the basis of authors’ experiences and case
studies.
