Heating system for performing seasonal solar energy storage with ground-source heat pump

Abstract

The invention discloses a heating system for performing seasonal solar energy storage with a ground-source heat pump. The heating system comprises a solar thermal collector (1), a thermal collection water tank (2), a ground temperature recording system (3), a plurality of underground buried pipe heat exchangers (4), a soil heat pump unit (5) and a heating user (6), wherein a signal input end of the ground temperature recording system (3) is connected with a signal output control line of a ground temperature measuring device buried underground; the underground buried pipe heat exchangers are buried underground and arranged in parallel connection; a pipeline water inlet of the heating user is communicated with a water supply outlet of the soil heat pump unit through a heating pipeline, and a pipeline water outlet of the heating user is communicated with a water supply and water return port of the soil heat pump unit through a water return pipeline. The heating system has the advantages of being simple in structure, reliable in control and economically feasible. Meanwhile, a large amount of solar energy heat is stored in the thermal storage process, and thus the soil temperature is raised and the system efficiency of the soil source heat pump is improved. The heating system for performing seasonal solar energy storage with the ground-source heat pump is economical and safe.

Description

technical field [0001] The invention relates to a heating system, in particular to a heating system using a soil source heat pump to store solar energy across seasons. Background technique [0002] Ground source heat pump technology is a high-efficiency energy-saving air-conditioning system that utilizes underground shallow geothermal resources. By inputting a small amount of high-grade energy, it realizes the process of transferring low-grade heat energy to high-grade energy, and has a high primary energy utilization rate. Usually the ground source heat pump consumes 1KW of energy, and the user can get more than 4KW of heat or cold, and the extra energy comes from the soil. In addition, the relatively constant temperature of the ground energy makes the operation of the heat pump unit more reliable and stable, ensuring the high efficiency and economy of the system. In winter, the heat in the soil is "taken" out to provide indoor heating; in summer, the heat in the room is t...
