Abstract

The invention relates to an indoor model test apparatus for ground source heat pump rock soil thermal response testing and an application thereof; the indoor model test apparatus comprises a model case, a soil model for test, a measurement module, a data acquisition module, a thermal cycle module, and a host PC computer; the soil model for test is disposed in the model case; the measurement module is disposed in the soil model for test; the thermal cycle module is connected with the soil model for test; the data acquisition module is connected with the measurement module; the data acquisition module is connected with the host PC computer. Compared with the prior art, the invention has the advantage that the indoor model test apparatus can not only calculate thermophysical parameters of heat exchange soil required by ground source heat pump buried pipe design, but also study environment effect of surrounding soil caused by long-term operation of the ground source heat pump system.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering ground source heat pumps, in particular to an indoor model test device for testing geotechnical thermal response of ground source heat pumps and its application. Background technique [0002] Ground source heat pump technology is a way for people to utilize shallow geothermal energy. Shallow geothermal energy is a part of geothermal resources. It is rich in resources, widely distributed, and stable in temperature. The development technology has reached maturity. It has been widely used in heating and cooling. It is a good alternative energy and clean energy. It is environmentally friendly, High efficiency and energy saving, low operating cost, sustainable utilization, mature technology, no consumption of groundwater, etc., have broad application prospects. [0003] For a long time, the design of ground source heat pump systems has been done by HVAC professionals. From their own ...
