The invention relates to a soil source-air source wind energy heat pump system and a control method thereof and is designed for improving the efficiency of a heat supplying system for a wind energy heat pump and solving the problem that heat absorption and heat extraction of soil in the using area of the wind energy heat pump are unbalanced. The soil source-air source wind energy heat pump system comprises a wind generating subsystem, an air-injection enthalpy-increasing low-temperature air source heat pump subsystem, a high-temperature-difference high-temperature water source heat pump subsystem and a heat and cold storage subsystem; by taking wind energy generation as a driving power supply and taking soil and air as low-temperature heat sources, the change of a wind load is handled and stable output of hot water / cold water is guaranteed by using a heat / cold storage water tank; the air is used as a low-temperature heat source at the low-peak time of heat supply, the soil is used as the low-temperature heat source at the high-peak time of the heat supply, and a ground source heat pump refrigeration mode is started in summer, so that the absorbed heat and the extracted heat of the soil are enabled to be basically balanced, and high-efficiency operation of a heat pump unit is guaranteed. According to the soil source-air source wind energy heat pump system disclosed by the invention, the heat pump unit can effectively utilize the air as an auxiliary heat source, so unbalanced heat absorption and heat extraction of the soil is overcome, the technical difficult problems of low heat supply efficiency, poor operation stability and reliability and the like of an air source heat pump in winter can be solved, and the aims of improving the energy efficiency ratio and the operation reliability of the unit are achieved.
Description
technical field [0001] The invention relates to a wind energy heat pump system, in particular to a soil source-air source composite heat source wind energy heat pump heating and cooling system and a control method thereof. Background technique [0002] my country is rich in wind energy resources. With the rapid development of the wind power industry in recent years, my country has become the country with the largest installed capacity of wind power in the world. Wind power plays an important role in energy supply. However, due to the influence of power grid operation and other factors, especially in winter heating During this period, the contradiction between the operation of wind turbines and cogeneration units was prominent, resulting in the wind turbines in the northern region being forced to abandon a large number of wind. The promotion of combined heating technology of wind energy and heat pump units is an important measure to absorb low-valley wind power, which can effec...
