Heat pump type ground energy storage air-conditioning system

Abstract

The invention provides a heat pump type ground energy storage air-conditioning system. The heat pump type ground energy storage air-conditioning system comprises a heat pump unit, an air-conditioning heat exchange tail end, a refrigerant and a refrigerant circulation system; the heat pump type ground energy storage air-conditioning system is characterized by further comprising a ground energy storage area; the ground energy storage area is formed by an energy storage body and a refrigerant pipe paved in the energy storage body, and the energy storage body is ground deep soil, rock, a civil engineering pile foundation or a closed water-bearing stratum; and the heat pump type ground energy storage air-conditioning system further comprises a soil energy collector paved on the shallow layer of the ground surface, and the soil energy collector is a plastic capillary network heat exchanger and used for collecting heat or cold in the soil. The problem that a conventional air-conditioning system is high in energy consumption can be solved, and the problems that at present, a ground source heat pump air-conditioner is strict in using condition and small in application scope are solved.

Description

technical field [0001] The invention relates to an air conditioning system. In particular, air-conditioning systems that use the soil as heat storage to cool or heat buildings. Background technique [0002] Conventional air-conditioning systems usually use fossil energy such as coal, oil or natural gas as the only direct or indirect source of cold and heat for air-conditioning and refrigeration. The consumption of these fossil energy causes environmental damage and aggravates environmental pressure. [0003] In order to solve the above problems and reduce the consumption of fossil energy, engineers have used the characteristics of the constant temperature zone of 15-150 meters underground rock and soil space, which is usually 10-18 °C, and the rock and soil usually have suitable heat capacity and heat conductivity. The ground source heat pump air-conditioning system is constructed by using it. About 20 years ago, my country introduced the ground source heat pump system fro...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a brand-new heat pump type ground heat storage air conditioning system, which can utilize the soil constant temperature zone as the cold and heat source of the air conditioning system to the greatest extent, thereby solving the relatively large limitation of the application range of the ground source heat pump and the energy consumption of conventional air conditioning higher question
