Ground-source heat pump system

Abstract

The invention discloses a ground-source heat pump system. The ground-source heat pump system comprises a ground-source heat pump unit, an indoor air discharge device and underground heat transfer units. The ground-source heat pump system is characterized in that each underground heat transfer unit comprises a heat transfer pipe, a connector and a plurality of elastic fixing unit bodies; the connectors are used for communicating of bottom ports of all the heat transfer pipes; each elastic fixing unit body comprises a spring and a circular ring, one end of each spring is fixed to the pipe wall of the corresponding heat transfer pipe, and the other end of the each spring is provided with the corresponding the circular ring; and the multiple elastic fixing unit bodies are arranged on the external walls of the heat transfer pipes at equal intervals, and the elastic fixing unit bodies are perpendicular to the axial directions of the heat transfer pipes. According to the ground-source heat pump system, it is ensured that the heat transfer pipes cannot move upwards, downwards, leftwards or rightwards in the construction process of engineering.

Description

technical field [0001] The invention relates to a ground source heat pump system. Background technique [0002] Ground source heat pump is a land shallow energy transfer from low-grade heat energy to high-grade heat energy by inputting a small amount of high-grade energy (such as electric energy). Usually the ground source heat pump consumes 1kWh of energy, and the user can get more than 4.4kWh of heat or cold. [0003] Ground source heat pump is one of the building energy saving and emission reduction technologies promoted and applied by the state; it is a device that uses underground buried pipe heat exchangers to exchange heat and cold with shallow underground geothermal resources, and realizes heating in winter and cooling in summer. double effect. However, due to the need to drill holes to bury heat exchangers and other work, the initial investment cost of the ground source heat pump system is relatively high, which limits its popularization and application. Therefor...

Problems solved by technology

The problem that often occurs in the actual embedding process is that each heat transfer tube is connected by a joint. After the heat transfer tube is placed inside the steel cage, due to the need to bury the soil later, the heat transfer tube will move up and down or left and right, resulting in heat transfer. The pipe cannot be placed vertically or the joints connecting the heat transfer pipe are loose and cause water leakage
