Soil source fuel gas heat pump system with heat balance active recovery function

Abstract

The invention relates to a soil source fuel gas heat pump system with the heat balance active recovery function. The soil source fuel gas heat pump system comprises a water source fuel gas heat pump unit and is characterized in that the water source fuel gas heat pump unit is respectively connected with a ground heat exchanger, a fan coil and a domestic hot water heat exchange tank through a heat pump unit ground source water electrically-operated valve, a heat pump unit electric valve and a heat recycling overhauling turn-off valve, the fan coil is connected with a fresh air handling unit, and the domestic hot water heat exchange tank is connected with a solar heat collector. The soil source fuel gas heat pump system has the advantages that a ground heat exchanging system serves as a cold and heat source of a fuel gas heat pump, the operation efficiency of the system can be improved, system energy consumption is reduced, heat balance active recovery of the ground heat exchanger can be conducted through the fresh air handling unit, cold and hold accumulation of the ground heat exchanger can be eliminated, the service life of efficient operation of the ground heat exchanger is prolonged, a system controller is arranged, the system can be scientifically and reasonably controlled to produce domestic hot water and heat balance recovery is conducted.

Description

technical field [0001] The invention relates to the technical field of heat pumps, in particular to a soil source gas heat pump system with the function of actively restoring heat balance. Background technique [0002] Ground source heat pump is a new type of air-conditioning technology that uses shallow ground energy for heating and cooling, which is highly efficient, energy-saving and environmentally friendly. The ground source heat pump utilizes the huge heat storage and cold storage capacity of the underground soil, through the pipeline system buried deep around the building or under the floor, adopts the heat pump principle, and realizes the transfer of low-level heat energy to high-level heat energy through a small amount of high-level electric energy input, so that the underground A technology for heat exchange between rock and soil mass and buildings. The ground source heat pump air conditioning system is mainly divided into three parts: the outdoor buried pipe heat...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to provide a soil source gas heat pump system with the function of active recovery of heat balance, so as to solve the problem that the existing ground source heat pump buried tube heat exchanger is prone to heat discharge or heat extraction to the ground during operation. Balance, resulting in heat accumulation or cold accumulation in the underground soil, the problem that the underground temperature cannot return to a reasonable range, thereby improving the operating efficiency of the ground source heat pump system
