Abstract

The invention relates to a testing device for a thermal response test of a ground-source heat pump system and belongs to the technical field of the ground-source heat pump systems. The device comprises a water-wind unit, two water pumps, a water tank, a turbine flowmeter, three platinum resistance temperature sensors and two stop valves, wherein the inlet of the water-wind unit is connected with the bottom outlet of the water tank and the outlet of the water-wind unit is connected with the inlet of the water tank by use of a pipeline to form an energy storage cycle; the first platinum resistance temperature sensor is arranged inside the water tank; the bottom outlet of the water tank is connected with the first stop valve by use of a pipeline with the second water pump and the second platinum resistance temperature sensor; a test hole formed in the bottom of the water tank is connected with the second stop valve by use of a pipeline with the turbine flowmeter and a third platinum resistance temperature sensor, and therefore, a test cycle is formed. The device is applicable to the earlier-stage thermal response test of the ground-source heat pump system; as a result, the reliability and the comprehensiveness of the thermal response test is improved, and the numerical accuracy of guidance is improved.

Description

technical field [0001] The invention belongs to the technical field of heat pumps, and in particular relates to the design of a thermal response testing device in a buried pipe ground source heat pump system. Background technique [0002] With the country's emphasis on energy conservation and emission reduction, new energy sources have been well promoted, and ground source heat pump systems, as a new energy source, are gradually being recognized. In the ground source heat pump system, the buried pipe system has been well applied. At present, according to the "Technical Specifications for Ground Source Heat Pump System Engineering": "3.2.2A The application building area of ​​the ground source heat pump system with local buried pipes is 3000-5000m 2 When the thermal response test of rock and soil should be carried out; when the application building area is greater than or equal to 5000m 2 , the geotechnical thermal response test shall be carried out. " [0003] At present,...
