A buried tube heat exchanger of a small ground source heat pump and a method for inserting buried holes into the ground

Abstract

The invention discloses a buried tube heat exchanger for a small ground source heat pump, which relates to the technical field of heat pump devices. Aiming at the existing problem of large engineering volume, the following scheme is proposed, which includes fixedly connected hot water tanks and cold water tanks , the inner walls of the hot water tank and the cold water tank are fixedly connected with filter plates, 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, and the other side of the discharge pipe One end is fixedly connected with a plurality of first condensation pipes arranged in parallel, and the end of the first condensation pipe away from the discharge pipe is connected with a second condensation pipe and a connecting pipe through a tee, and the lower end of the second condensation pipe is fixedly connected with a communication pipe. Tube, the present invention is simple in structure, easy to use, can carry out heat exchanging function very well, reduces volume, reduces excavation engineering quantity, saves cost, controls flow at the same time, saves energy.

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...
