Abstract

An energy system of a solar energy composite ground source heat pump comprises an air conditioner, a domestic hot water supply device, a solar energy heat-collecting device, a heat storage unit, a ground source heat pump system, a ground heat exchanger, an auxiliary heating device, a first electric three-way valve and a second electric three-way valve, wherein the first electric three-way valve or the second electric three-way valve is communicated with the air conditioner, the heat storage unit is communicated with the domestic hot water supply device; and the ground heat exchanger and the ground source heat pump system are separately communicated with the first electric three-way valve, the ground source heat pump system and the heat storage unit are separately communicated with the second electric three-way valve, and the solar energy heat-collecting device and the auxiliary heating device are separately communicated with the at heat storage unit. By adopting the structure, the invention organically combines the technologies of applications of the solar energy light-heat, ground source heat pump air conditioner, biomass energy and the like with buildings, and can be used for refrigeration in summer, heating in winter and hot water supply in four seasons and can also largely reduce the energy consumption of buildings, thus having significant social, economic and environmental benefits.

Description

technical field [0001] The invention belongs to the field of energy, and relates to an energy generation system, especially a renewable energy system. Background technique [0002] The ground source heat pump uses the characteristics of relatively constant temperature and high heat capacity of the underground soil or nearby water sources. In summer, the heat required for the air-conditioning refrigeration cycle is discharged to the ground, and in winter, the heat required for the air-conditioning refrigeration cycle is absorbed from the soil or It is taken out from the nearby water source to achieve the purpose of improving the cooling and heating efficiency in winter and summer at the same time. At present, domestic ground source heat pumps are developing the fastest, and the construction area used by the largest single project has reached 130,000 square meters. Statistics show that in 2005, the application area of ​​my country's ground source heat pump system was about 30...
