Abstract

The invention belongs to test equipment and particularly relates to a variable frequency heat pump type rock-soil thermal property tester. The tester comprises a heat pump unit, wherein the outlet pipeline of the heat pump unit is communicated with the inlet pipeline of the heat pump unit through a buried pipe, temperature sensors, flow sensors and water supplementing buckets are arranged on the outlet pipeline and inlet pipeline of the heat pump unit, and the temperature sensors and the flow sensors are electrically connected with a central control system; the heat pump unit is electrically connected with the central control system through a frequency changer, and the heat pump unit is electrically connected with a draught fan coil system. The tester provided by the invention can be used for solving such problems in the prior art as troublesome testing method and process and loose equipment structure, and the tester has the advantages of compact structure design, simple testing process, little investment, accurate testing structure, and the like.

Description

technical field [0001] The invention belongs to testing equipment, in particular to a frequency conversion heat pump type rock and soil thermophysical property tester. Background technique [0002] Ground source heat pump is a high-efficiency and energy-saving air-conditioning system that uses shallow geothermal resources on the ground as a heat source or a cold source to provide both heating and cooling. The heat exchanger of the ground source heat pump is buried underground to exchange heat and cold with the earth. The soil has good heat storage performance, and the soil temperature fluctuates less throughout the year and the value is relatively stable. The soil source heat pump system utilizes this feature of the soil, making its operating efficiency 40%-60% higher than that of traditional air conditioners, and the energy saving effect is obvious. Ground source heat pumps have been widely used in my country in recent years. [0003] The ground source heat pump realizes...
