The invention relates to a ground source
heat pump-based soil thermophysical property tester and a testing vehicle. The tester comprises a variable-frequency
heat pump unit, a first
closed loop and a second
closed loop; a condenser, a variable-frequency compressor, an
evaporator and a throttling element are sequentially connected through tubes to form the variable-frequency
heat pump unit; the hot water outlet end of the condenser is sequentially connected with a first variable-frequency water pump, a first temperature sensor, a first
electromagnetic flowmeter, a first buried tube, a second temperature sensor and the cold water inlet end of the condenser through tubes, so that the first
closed loop is formed; and the cold water outlet end of the
evaporator is sequentially connected with a second variable-frequency water pump, a third temperature sensor, a second
electromagnetic flowmeter, a second buried tube, a fourth temperature sensor and the hot water inlet end of the
evaporator through tubes, so that the second closed loop is formed. The tester overcomes the limitation of the conventional testing method, testing is not affected by
outdoor temperature, the equipment number is reduced, the principle is simple, the structure is compact, and the tester is easy to operate.
