Well depth detecting device for ground-source heat pump

Abstract

The invention discloses a well depth detecting device for a ground-source heat pump. The well depth detecting device comprises a U-shaped buried pipe, the two ends of the U-shaped buried pipe extend out of the ground and are each horizontally connected with a connecting pipe, one end of the U-shaped buried pipe is connected with an air compressor through the corresponding connecting pipe, the other end of the U-shaped buried pipe is connected with a water filling nozzle of a transparent water tank through the corresponding connecting pipe, and the connecting pipe between the air compressor and the U-shaped buried pipe is further provided with a pressure meter; and the U-shaped buried pipe is full of water in advance. The well depth detecting device for the ground-source heat pump is simple, practical, easy to manufacture and implement and short in detecting time.

Description

technical field [0001] The invention relates to the field of ground source heat pump drilling detection, and mainly relates to a ground source heat pump well depth detection device. Background technique [0002] The ground source heat pump system uses water and ground energy (ground water, soil, surface water) to exchange cold and heat through buried pipes, thereby exchanging cold and heat. In the early stage of construction, it is necessary to conduct soil thermal response experiments on the well-drilled land to measure the heat transfer per linear meter of the buried pipe in the well-drilled land in summer and winter, and determine the number of wells to be drilled according to the design load of the above-ground buildings and depth. Therefore, in actual construction, it is necessary to ensure that the depth of drilling and the amount of pipe running meet the design requirements, so as to ensure the heat exchange effect of the ground source heat pump system used by users....

AI Technical Summary

Problems solved by technology

[0003] However, in the construction process of ground-source heat pump drilling and running pipes, it is difficult to detect hidden works such as well drilling depth and pipe running volume, so the actual pipe running volume has a direct impact on the heat exchange surface required by the design.
