Research status and application analysis of condense heat recovery in small sized air conditioners

Analyses the feasibility of recycling condense heat for heating domestic hot water. Reviews the research status of condense heat recovery in small sized air conditioners at home and abroad on the basis of its successful application to large central air conditioning systems. Considers that there will be a long way to go before going into production. Aiming at the application in China, points out several research aspects. At last, recommends a modified system that could be used in China. Presents the  principle and the study status of the system, and indicates several problems needed to be solved in its manufacturing.
