Abstract

The invention relates to a heat balance and heat recovery system for a ground-source heat pump, and belongs to the technical field of ground-source heat pump systems. The heat balance and heat recovery system for the ground-source heat pump comprises a heat pump host, a circulating water pump, buried pipes, an energy tower heat pump, a cold water tank, a hot water tank and a thermoelectric generator, wherein the heat pump host, the circulating water pump, the hot water tank, the buried pipes and the hot water tank are sequentially connected to form a first loop, and the heat pump host, the circulating water pump, the cold water tank, the buried pipes and the hot water tank are sequentially connected to form a second loop; and one end of the energy tower heat pump is connected between the buried pipes and the hot water tank, the other end of the energy tower heat pump is connected between the buried pipes and the cold water tank, and the thermoelectric generator is connected between thecold water tank and the hot water tank. By means of the structure, two loops and the energy tower heat pump are arranged to regulate the hot and cold balance around the buried pipes, so that the operation efficiency of the heat pump host is improved; and the thermoelectric generator generates power by means of a temperature difference between the two ends of circulating water, the system heat isfully recycled, energy consumption is reduced, and the energy is saved.

Description

technical field [0001] The invention belongs to the technical field of ground source heat pump systems, and in particular relates to a ground source heat pump heat balance and heat recovery system. Background technique [0002] Ground source heat pump is a high-efficiency energy-saving air-conditioning system that uses underground shallow geothermal resources (also called ground energy, including groundwater, soil or surface water, etc.) to provide both heating and cooling. The ground source heat pump realizes the transfer of heat energy from low temperature to high temperature by inputting a small amount of high-grade energy (such as electric energy). The ground energy is used as the heat source of heat pump heating in winter and the cold source of air conditioning in summer, that is, in winter, the heat in the ground energy is "taken" out, and after raising the temperature, it is used for indoor heating; in summer, the heat in the room is taken out and released Go to the ...
