Description

technical field [0001] The invention mainly relates to the field of thermal response testing of low-grade heat sources of ground source heat pumps. It is especially suitable for the field of thermal physical property testing of underground rock and soil. Background technique [0002] Ground source heat pump air-conditioning technology is a new type of air-conditioning system that uses renewable energy such as underground soil, surface water, and groundwater. Due to its low-carbon and environmentally friendly features, it is currently widely used. Among them, the thermophysical parameters of low-grade heat sources are of great significance to the design and later operation of the ground source heat pump air conditioning system. [0003] However, due to the complexity of geological conditions, the empirical design parameters often have large deviations. Only the field test method can accurately measure the parameters of low-grade heat sources, and provide accurate data for th...

Problems solved by technology

[0003] However, due to the complexity of geological conditions, the empirical design parameters often have large deviations. Only by using the field test method can the parameters of low-grade heat sources be accurately measured, and provide accurate data for the design and simulation research of ground source heat pump air conditioning systems.

[0004] However, the geographical location of the test site is scattered and the test period is short. Most of the tests now use wired serial communication with a short test distance. Field tests are easily affected by complex factors such as terrain, climate, and environment.
