Problems solved by technology

This article also introduces the test device for the capacity of the buried tube heat exchanger. The shortcomings of this device are as follows: 1. It can only measure the heat transfer capacity of the buried tube heat exchanger under one working condition at the same time. It is not possible to test the heat transfer capacity of the buried tube heat exchanger under two working conditions at the same time; 2. It must be equipped with another set of air cooling and heat source facilities; 3. The test devices reported are all experimental laboratories of universities or research institutes It is not suitable for engineering construction testing, and it is very inconvenient to move

Abstract

A device for testing heat exchanging ability of burying heat exchanger consists of geothermal pump airconditioning set, burying heat exchanging heat absorption system which is an independent water circulation loop formed by pump, water collector, valve pipe etc; burying heat exchanging heat release system which is an independent water circulation loop formed by pump, water collector, valve pipe, etc; and test system formed by thermometer and turbine flowmeter which are set separately in abovesaid heat release and heat absorption systems.

Description

Technical field [0001] The invention relates to a method for testing the heat exchange capacity of an underground tube heat exchanger of a buried tube type ground source heat pump in HVAC engineering technology and a special testing device thereof. Background technique [0002] Ground source heat pump (GSHP) systems include heat pump systems that use soil, groundwater, and surface water as heat and sink sources. The ground source heat pump system using soil is also called underground heat exchanger ground source heat pump system or buried pipe ground source heat pump system; it is the most technically difficult of the three forms of ground source heat pump systems, but it is also the most widely used form. "Modern Air Conditioning" published an article entitled "Ground Source Heat Pumps in China" in the third issue of 2001, pointing out that: in foreign countries, the main research and application objects of ground source heat pumps are ground sourc...
