Ground-cooled type heat exchange method, heat exchange system, air conditioner and mounting method

Abstract

The invention discloses a ground-cooled type heat exchange method, a heat exchange system, an air conditioner and a mounting method. The heat exchange system comprises a compressor, a ground cooling pipeline, a throttling device and an evaporator which are sequentially connected by pipelines, wherein at least part of the ground cooling pipeline is located under the ground, one end of the ground cooling pipeline is directly or indirectly connected with an air outlet of the compressor, and the other end of the ground cooling pipeline is directly or indirectly connected with a liquid inlet of thethrottling device. By arranging the ground cooling pipeline located under the ground and utilizing underground natural low temperature to carry out heat exchange with a gas refrigerant coming out ofthe compressor, the heat exchange process of a condenser and a condensing fan in the prior art is replaced, and energy consumption is greatly reduced; as underground temperature is low and far lower than the condensing temperature of the refrigerant, the heat exchange efficiency is high; and at the same time, the outdoor unit is omitted, the size of the whole machine is smaller, and installation is convenient.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a ground cooling heat exchange method, a heat exchange system, an air conditioner and an installation method. Background technique [0002] The heat exchange system in the existing air conditioner generally consists of a compressor, a condenser, a throttling device and an evaporator connected in sequence. The refrigeration heat exchange process is as follows: the compressor absorbs and compresses the refrigerant gas evaporated by the evaporator, and provides power for the refrigerant to circulate while increasing the pressure and temperature; the high-temperature and high-pressure refrigerant gas from the compressor passes through the condenser in the The heat is discharged outward under the action of the fan blades, and condensed into a medium-temperature and high-pressure refrigerant liquid; the refrigerant liquid coming out of the condenser is depressurized through th...

AI Technical Summary

Problems solved by technology

[0004] At the same time, the existing air conditioners generally include an indoor unit and an outdoor unit, resulting in a large size of the whole unit.

Moreover, since outdoor units are generally installed outdoors, ordinary consumers cannot install them by themselves, and professional operators are required to install them, resulting in increased installation costs
