SCA1000 Underground pipes, shaft, ground source heat pump

Ground-source heat pump air-conditioning system uses the soil as the heat source or heat sink of the underground pipe heat exchanger to heat and cool the building. In the design of ground heat exchanger, soil thermal conductivity is a very important parameter. And long-term reliable monitoring of ground temperature is particularly important. When the soil thermal conductivity is measured in the field, the test time should be long enough, the temperature of the fluid inlet and outlet and the depth of the fluid after the stable working condition will influence the accuracy of the test result.
