INVESTIGATION OF COMPOUND CONDENSING METHODS FOR BUILDING COOLING AND HEATING SOURCES
The situation of energy consumption for building cooling and heating sources in China is intorduced in this article. Then this paper proposed a concept of compound condensing based on recent engineering practice associated with condensing heat recovery of water chiller unit and heat pump in China and discussed some primary methods of compound condensing. These compound condensing methods have been already adopted in the fileds such as piston-style water chillers, centrifugal-style water chillers and air heat pumps, . The capacity of the condensing heat of these water chillers and heat pumps is great when air-conditioning system is running. But the condensing heat is directly expelled to the environment without being used. So these compound condensing methods are considered as a new technique of heat recovery for building cooling and heating resources. And some experiments on water chiller and air source heat plant are validated. These new compound condensing methods can increase the EER of the system greatly and make great benefit to the environment, economics and society.
compound condensing methods condensing heat recovery EER building heating and cooling sources.
