A detection device for ground source heat pump buried pipe system

Abstract

The invention discloses a detection device of a buried pipe system of a ground source heat pump. The detection device comprises a water tank, a circulating water pump and buried pipe connectors which are arranged at the two ends of a pipeline and are connected with buried pipes, wherein the water tank, the circulating water pump and the buried pipe connectors are connected in sequence to form a water circulating branch; the buried pipe connectors comprise a water inlet and a water returning opening. The detection device further comprises a cold and heat source, an external connection pipeline, a booster pump and a measurement water tank, wherein one end of the cold and heat source is connected with the water tank and the other end of the cold and heat source is connected with a buried pipe water returning pipeline of the water circulating branch; one side of the external connection pipeline is connected with the water inlet of the buried pipe connectors of the water circulating branch; the booster pump and the measurement water tank are connected onto the external connection pipeline. According to the detection device disclosed by the invention, various detection manners of the buried pipe system are integrated, the depth of the buried pipes can be measured, the water pressure of the buried pipes can also be detected and the heat rejection capacity in summer and the heat absorption capacity in winter of the buried pipes can be detected; the construction quality of a single buried pipe system and a plurality of buried pipe systems can be detected.

Description

technical field [0001] The invention relates to a detection device for an underground pipe system of a ground source heat pump. Background technique [0002] As a renewable energy HVAC technology, ground source heat pump is an efficient and energy-saving technology commonly used in the field of building energy conservation in the world, and has a development history of more than 10 years in my country. In recent years, the ground source heat pump industry has achieved remarkable rapid development, but there are many difficulties and problems in the development process. [0003] When designing the geothermal heat exchanger of the ground source heat pump system, it is necessary to know the heat transfer performance of the buried pipe. The traditional method of determining the heat transfer of buried pipes is to first drill a test hole, determine the geological composition around the borehole according to the samples taken out, then put the buried pipe into the test hole, and ...

Problems solved by technology

However, this type of device can only be tested for a single item in the early stage or during the design and construction of the buried pipe

[0004] During the construction of buried pipes, there are various possibilities that may cause construction quality problems of the buried pipe system, for example, the depth and backfilling do not meet the design requirements, etc.

These problems will cause the ground source heat pump system to fail to meet the load design requirements.

[0005] However, in the prior art, there is no testing device that can detect the construction quality of the ground source heat pump buried pipe system.

Due to the lack of necessary construction quality testing methods, in order to ensure the load of the ground source heat pump system, the design margin of the ground source heat pump has been continuously increased, thereby increasing the initial investment and causing unnecessary waste
