Test and analysis for lake-water source heat pump air conditioning system in People’s Hospital of Kaixian, Chongqing

Based on the field test of the system in the project, analyses the temperature difference of the lake-water in natural condition and system operating condition in different depths, the water temperature change with the distance of testing site to water exhaust site and the temperature difference between water intake and the inlet of heat exchanger. Summarizes the operating condition and the influence of water temperature change on system operation and gives some advices based on the test and analysis results.
