Problems solved by technology

In the cold season, when the temperature of the evaporating section is higher than that of the cooling section, the refrigerant starts to circulate; in the warm season when the thermal erosion is the most serious, when the temperature of the evaporating section is higher than that of the cooling section, the cooling medium stops circulating. The heat pipes stop working, and the permafrost cannot be protected

Abstract

The invention discloses a method for driving a compressor to refrigerate to maintain the thermal stability of a frozen soil foundation by using solar energy and wind energy. The method adopts two parts, namely solar energy and wind energy-driven refrigeration devices and an arranging and embedding mode, wherein each refrigeration device comprises an internal heat-collecting heat pipe; a compressor refrigeration device is arranged on a transition segment of each heat pipe; a compressor refrigeration control box is arranged at the lower part of an evaporation segment of each heat pipe; a solar photovoltaic panel and a wind energy generator are arranged at the middle part and the top part of the evaporation segment of each heat pipe; and the compressor refrigeration devices are provided with power through the output power of the wind energy generators and the solar photovoltaic panels. The arranging and embedding mode comprises the content as follows: a condensation segment of each internal heat-collecting heat pipe is completely buried into a soil layer; the lower end of each compressor refrigeration device arranged on the transition segment is buried at 0.1-0.3m below the soil layer; and the evaporation segment of each heat pipe is arranged in the atmosphere. The whole solar energy and wind energy-driven refrigeration devices are buried at two sides of a roadbed or a foundation side by side and the buried spacings between the refrigeration devices are controlled between 2.0m and 5.0m.

Description

technical field [0001] The invention relates to a method for maintaining thermal stability of permafrost foundations, in particular to a method for maintaining thermal stability of permafrost foundations by using solar energy and wind energy to drive compressor refrigeration heat pipes. Background technique [0002] In the thermal stability operation and maintenance of permafrost foundations and subgrades, heat pipe refrigeration devices are widely used. The heat pipe is a sealed tube heat conduction device with two convective circulation of vapor and liquid. It is mainly composed of two parts: the evaporation section and the heat dissipation section. The evaporation section is placed in the permafrost layer, the heat dissipation section is placed in the atmosphere, and the refrigerant is filled in the in. In the cold season, when the temperature of the evaporating section is higher than that of the cooling section, the refrigerant starts to circulate; in the warm season wh...
