Vehicle-mounted physical parameter tester of geological heat of ground source heat pump

Abstract

The invention discloses a vehicle-mounted physical parameter tester of geological heat of a ground source heat pump. The physical parameter tester comprises a heat-insulating water tank, an electrical heating tube, a circulating pump for a buried tube, a circulating pump for an evaporator, an air-cooled heat pump unit consisting of the evaporator, a compressor, a condenser, an expansion valve and a fan, and a controller. In the vehicle-mounted physical parameter tester of the geological heat of the ground source heat pump, the cold and heat source is provided by the air-cooled heat pump unit, so the whole tester has a compact structure, can be placed on a vehicle, and is very flexible and convenient to use. In addition, the cold and heat source mainly comes from air, so that other cooling and heating facilities are not needed. During testing, only a group of heat exchangers for the buried tube are needed to be buried, so that the testing cost can be greatly reduced. As the tester can be used for cooling (preparing cold water) and heating (preparing hot water), only one tester can meet the testing requirements of a thermal response method and a simulation method. Therefore, the tester is dual-purpose, and has a wide application range. In addition, the tester has high automation degree.

Description

Vehicle-mounted ground source heat pump geothermophysical parameter tester technical field The invention relates to a test device, in particular to a vehicle-mounted ground source heat pump geothermophysical parameter tester. Background technique The essence of ground source heat pump technology is to use a drilling machine to drill a hole in the ground, then bury a U-shaped tube made of PE plastic and professionally called a buried tube heat exchanger into the hole, and then inject it into the buried tube heat exchanger. The heat exchange medium is injected, and heat or cold is absorbed from the earth through the heat exchange between the heat exchange medium and the earth, and then the heat exchange medium provides the heat or cold to the heat pump unit for adjusting the temperature of the indoor space. When the heat exchange medium takes heat from the ground, it can provide heat for the heat pump unit, and when the heat exchange medium releases heat to the ground, it ca...

AI Technical Summary

Problems solved by technology

1. The cold and heat source is provided by the water-cooled heat pump unit. During the test, at least three sets of buried pipe heat exchangers need to be buried at the test site, one for testing, and the other two for the water-cooled heat pump unit. This will not only cause The test cost increases, and the other two sets of buried tube heat exchangers may interfere with the tested buried tube heat exchanger

2. Since the test device adopts a water-cooled heat pump unit, the whole equipment is bulky, so it is inconvenient to carry, and it must be equipped with hoisting and transporting equipment before it can be sent to the test site
