Portable geotemperature energy thermal response testing equipment

Abstract

The invention discloses a portable geothermal energy thermal response testing device, which comprises a water tank, a water outlet pipe and a water return pipe connected with an underground pipe to form a closed circulation system, an electric heater, a water pump and a control system; The water outlet connected by the pipe, the beginning of the return pipe is provided with the return port connected with the buried pipe; the electric heater is arranged on the outlet pipe; the water pump is arranged on the inlet side of the electric heater to provide circulation power; the inlet of the water tank and the water pump Side pipe connection; the electric heater and water pump are connected to the pipe in a detachable connection. The thermal response testing equipment of the present invention has the advantages of small size, easy to carry, convenient disassembly and assembly, easy assembly and maintenance; the circulation system and the control system are integrated into one body, and the operation is convenient and simple; and it has a self-cleaning function, which can prolong the service life of the equipment .

Description

technical field [0001] The invention relates to the technical field of shallow geothermal energy exploration and preliminary investigation and testing of a ground source heat pump system, in particular to a portable geothermal energy thermal response testing device. Background technique [0002] In the design of ground source heat pump system, the thermal response test of steady heat flow is usually used to calculate the comprehensive thermal physical properties parameters of rock and soil. , outlet water temperature, flow rate and other data, and use the heat transfer model to calculate the thermal physical parameters such as the average thermal conductivity of rock and soil. In the prior art, the in-situ thermal response test equipment generally has the disadvantages of being too large, not suitable for carrying, inconvenient to disassemble and assemble, and requiring too much water and electricity. As a result, it often occurs that the site cannot meet the above test cond...
