Description

technical field [0001] The invention relates to the technical field of surface water source heat pumps, in particular to a method and device for optimizing energy consumption of a surface water source heat pump system based on MATLAB. Background technique [0002] A surface water source heat pump system is a heat pump system that uses water drawn from wells or rivers as the heat source (or cold source). It uses the stable temperature and remarkable heat dissipation of pool water or lake water to heat (or cool) small and medium-sized areas. At present, the surface water source heat pump system can be divided into closed system and open system. The closed system consists of a surface water heat exchanger in potential surface water, and an adjacent water-water or water-air heat pump; the open system is directly pumped to the heat pump unit after the surface water is treated, or through an intermediate The heat exchanger is connected to the closed system. [0003] But also th...
