Problems solved by technology

Closed water source heat pumps do not require complex filtering devices. After using the front-end heat exchanger to exchange heat with the water body, they are used for water source heat pump work, and the heat transfer efficiency is low; open water source heat pumps directly drive the water body for heat exchange. The utilization rate is high, but the front-end heat exchange device needs to be equipped with a relatively complicated water filtration device, which requires a large investment and complicated maintenance

Abstract

The invention relates to the technical field of geothermal utilization, in particular to a geothermal utilization system of areas adjacent to a control flood dyke. The geothermal utilization system comprises a geothermal collecting device, a water source heat pump and an output device which are sequentially connected in series. Heat of water in a geothermal well is absorbed through the geothermal collecting device and supplied to the water source heat pump. Heat exchange is conducted on a sufficient water source in the control flood dyke through stratums. Water is filtered through a filter in the geothermal well, enters the geothermal well and directly enters the water source heat pump to be subjected to heat exchange. Then heat is input into soil of a greenhouse through a ground bed coil pipe in the output device. Cold and heat exchange between water and the greenhouse is achieved, the constant-temperature effect in the greenhouse is achieved, the heat exchange efficiency is high, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to the technical field of geothermal utilization, in particular to a geothermal utilization system in the vicinity of a flood control embankment. Background technique [0002] With the maturity of water source heat pump technology, its utilization is gradually approaching people's life. How to use heat pump technology in different regions and environments according to local conditions has also become a relatively cutting-edge topic. In the area near the flood control levee, the water source is abundant, and the soil is mainly sandy soil layer on the surface and gravel layer below, which is suitable for the development of planting. In the modern planting industry, the off-season vegetables with high economic benefits have been well practiced in building constant temperature greenhouses near the flood control embankment. However, due to the high construction cost of the constant temperature system, the price of vegetables remains hi...
