Air-conditioning system

Abstract

The invention relates to the technical field of air conditioners and particularly provides an air-conditioning system. The air-conditioning system aims to solve the problem that the refrigerating or heating effect of an existing air conditioner is not ideal. For this purpose, the air-conditioning system comprises a compressor, an outdoor unit and an indoor unit and further comprises a heat exchanging device. The heat exchanging device is used for enabling a refrigerant flowing out of the indoor unit to be subjected to heat exchanging with a refrigerant flowing out of the outdoor unit. By adopting the air-conditioning system, the refrigerant flowing out of the indoor unit can be subjected to heat exchanging with the refrigerant flowing out of the outdoor unit to increase the vaporization temperature of a low-temperature and low-pressure gaseous refrigerant and decrease the condensing temperature of a high-pressure and high-temperature liquid refrigerant, thus the refrigerating or heating effect of an air conditioner is improved, running away of the refrigerants can further be avoided, the loss of the refrigerating or heating capacity of the air conditioner is avoided, and the use experience of a user is improved accordingly.

Description

technical field [0001] The invention relates to the technical field of air conditioning, and specifically provides an air conditioning system. Background technique [0002] Air conditioning refers to the process of regulating and controlling the ambient air in a building or structure by artificial means. In order to improve the freedom of air conditioner installation, the longer the refrigerant piping between the indoor unit and the outdoor unit, the more convenient it is for consumers to install, but the increase in the length of the refrigerant piping will cause the cooling or heating capacity of the air conditioner to be lost. To make up for this loss, it is necessary to increase the subcooler to increase the subcooling degree of the refrigerant. [0003] In the prior art, the subcooler is connected in series between the outdoor unit and the indoor unit, and controlled by the electronic expansion valve installed between the subcooler and the outdoor unit, a part of the h...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the problem of unsatisfactory refrigeration or heating effects of the existing air conditioners, the present invention provides an air conditioning system. The air conditioning system includes a compressor, an outdoor unit and an indoor unit. The air conditioner, outdoor unit and indoor unit form a closed-loop circulation main circuit. The air conditioning system also includes a heat exchange device, which is used to exchange heat between the refrigerant flowing out of the indoor unit and the refrigerant flowing out of the outdoor unit.
