Abstract

The invention relates to a novel ground source heat pump coupling solar heating system, and aims to solve the problem that an existing ground source heat pump heating technology and a solar heating technology are applied only to regions where heating is needed in winter and cooling is omitted in summer. According to the novel ground source heat pump coupling solar heating system, the ground sourceheat pump heating technology and the solar heating technology are effectively coupled, so that the heat supplement problem in summer of the ground source heat pump heating technology as well as the overheating problem in summer of the solar heating technology are solved; and meanwhile, a ground source heat pump can also serve as an auxiliary heat source, which can overcome the insufficiency in the heat supply amount of a solar heating system. In addition, after both technologies are coupled, each of a ground source side and a heat storage water tank side can be used as a heat exchange side ofthe ground source heat pump, so that the heat extraction reliability of the ground source heat pump is increased, and the heat supply performance coefficient COP of the ground source heat pump is improved; and meanwhile, waste heat of a water tank is fully utilized, the water temperature of the water tank is reduced, and therefore the heat collection efficiency of a heat collection system is improved.

Description

Technical field [0001] The invention belongs to the technical field of ground source heat energy, and specifically relates to a novel ground source heat pump coupled solar energy functional system. Background technique [0002] Ground source heat pump technology is an energy-saving technology that effectively utilizes the energy storage capacity of the soil. In winter, the heat absorbed from the soil is improved by the heat pump to heat the building, and at the same time, the temperature in the ground is reduced, that is, the cold is stored, which can be used in summer; in summer, the heat in the building is transferred to the ground through the heat pump. Cool down the building while storing heat in the ground for use in winter, as attached figure 1 Shown. A typical solar heating system is attached figure 2 Shown. According to the characteristics of different cycles of the system, it can be divided into forced circulation indirect system, forced circulation direct system, dir...
