Applicability of Source Water Source Heat Pump System in Hot Summer and Warm Winter Area

Abstract

Water source heat pump with relatively stable surface water as heat transfer medium is a new type of energy-saving and temperature-regulating equipment. Its refrigeration and heating coefficients are 3.5-4.5 high. Water source heat pump has been widely used in refrigeration and heating of buildings in many foreign countries as an important energy-saving equipment. The number of water source heat pump energy stations has increased by 10% annually. The traditional coal pans used in large greenhouses in China often have some problems, such as low thermal efficiency, high energy consumption, high pollution and difficult cooling in summer. It is very helpful to use water source heat pump technology reasonably to solve these problems. In this paper, the water source heat pump air conditioning system is used in public places for experimental testing and research. The operation performance of the water source heat pump energy station is studied through experimental tests, which can provide reference for the popularization and application of the technology in hot summer and warm winter areas. The research contents of this subject are as follows: Under the rated operating conditions of the water source heat pump air conditioning system; the operation performance of the heating system is analyzed; Understanding and mastering the operation performance of water source heat pump air conditioning system, and comprehensively analyzing the stability and energy efficiency ratio of the system; The main problem to be solved is that it can not only ensure the operation cost unchanged or even reduce, but also improve the heating efficiency of water source heat pump air conditioning system.
