Construction method of underground heat transfer pipe of ground source heat pump system

Abstract

The invention discloses a construction method of an underground heat transfer pipe of a ground source heat pump system. The construction method comprises steps as follows: step 1), a rope is prepared, one end of the rope is fixed, and the other end of the rope penetrates through circular rings of all elastic fixing units; step 2), two ends of the rope are held, a heat transfer pipe is arranged in a cylindrical steel reinforcement cage, the rope is pulled hard upwards by hands in a placement process, so that the elastic fixing units bear upward tension force, at the moment, the elastic fixing units can deform, and the upward tension force guarantees that the heat transfer pipe can be placed in the cylindrical steel reinforcement cage very easily; step 3), when the heat transfer pipe is placed in the steel reinforcement cage, the tension force is not applied to the rope any more, one end of the rope is held by the hands, the other end is loosened, and the rope is drawn out from the circular rings.

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

A long-standing problem 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, the heat transfer tube will move up and down or left and right due to the need to bury the soil in the later stage, resulting in the heat transfer tube It cannot be placed vertically or the joints connecting the heat transfer tubes are loose and cause water leakage
