The energy saving potential analysis of air conditioning exhaust heat recovery is applied in China

Introduced the working principle of air conditioning exhaust heat recovery system and analyzed the outdoor temperature and the enthalpy value′s hourly running parameters of different areas.On the basis of meteorological data dynamic analyzed the adaptability and the choice of the ways of heat recovery in different typical climatic regions in China.The energy saving potential was analyzed and then it obtained the adaptation range of heat recovery system in different climatic regions.The study shows that energy saving effect of exhaust heat recovery unit is obvious.
