Abstract

Abstract: The heating system based on the underground water source heat pump is energy saving and environment friendly, but its operation effect in the cold area of Northwest China is rarely reported. The heating area of the underground water source heat pump system located in No.2 Middle School, Zhangye city, is 72755 m 2 . The system mainly consists of two sets of heat pump systems in parallel and each system includes a small-capacity heat pump in series with a high-capacity heat pump. Some parameters are tested from Jan. 25 to Mar. 31, 2016. Based on the test data, this paper calculates and analyses the energy utilization of the system. The heating effect of the system is good and the coefficient COP of the heating system, the high-capacity heat pump and the small-capacity heat pump are 3.67, 4.3 and 6.24 respectively.
