Buried pipe heat exchanger of small ground source heat pump and buried hole entering method thereof

Abstract

The invention discloses a buried pipe heat exchanger of a small ground source heat pump, and relates to the technical field of heat pump devices. The buried pipe heat exchanger of the small ground source heat pump provides the following scheme for solving the problem that the existing engineering quantity is large, the buried pipe heat exchanger comprises a hot water tank and a cold water tank which are fixedly connected, filter plates are fixedly connected to the inner walls of the hot water tank and the cold water tank correspondingly, the upper side of the hot water tank is fixedly connected with a water inlet pipe, the bottom of the hot water tank is fixedly connected with a discharge pipe, the other end of the discharge pipe is fixedly connected with a plurality of first condensationpipes arranged in parallel, and the ends, away from the discharge pipe, of the first condensation pipes are connected with second condensation pipes and connecting pipes through tee joints, and the lower ends of the second condensation pipe are fixedly connected with communicating pipes. The buried pipe heat exchanger of the small ground source heat pump is simple in structure and convenient to use, the heat exchange function can be well achieved, the size is reduced, the excavation work amount is reduced, the cost is saved, meanwhile, the flow is controlled, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of heat pump devices, in particular to a buried pipe heat exchanger of a small ground source heat pump. Background technique [0002] Greenhouses need to maintain a constant temperature, constant temperature material heating and other methods to achieve, for example, ground source heat pump is one of the heating methods. The ground source heat pump is a device that transfers low-grade heat energy to high-grade heat energy by inputting a small amount of high-grade energy (such as electric energy) from shallow land energy. Usually the ground source heat pump consumes 1kWh of energy, and the user can get more than 4.4kWh of heat or cold, and then needs to exchange heat with the ground to realize the function. However, although the heat exchanger of the existing structure can perform heat exchange, the general pipeline With the U-shaped structure, the same volume requires a large area for excavation, which incr...
