Supercooling device for air conditioner and air conditioner

Abstract

The invention relates to the technical field of air conditioners, and provides a supercooling device for an air conditioner and the air conditioner in order to solve the problems of high cost and easyloss of refrigerant energy of an existing supercooling device for the air conditioner. The air conditioner comprises a condenser and a water receiving tray. An outlet of the condenser is connected with a refrigerant main pipeline. The water receiving tray is used to collect condensate water produced in the refrigeration process of the air conditioner. The supercooling device comprises a condensate water circulation pipeline. The condensate water circulation pipeline comprises a heat exchange pipe section. The heat exchange pipe section is arranged to enable the condensate water to exchange heat with refrigerant in the refrigerant main pipeline to improve the supercooling degree of the refrigerant. The supercooling device can improve the supercooling degree of the refrigerant by utilizingthe heat exchange between the low temperature condensate water and the refrigerant, so that the flash phenomenon of the refrigerant is avoided, the uniformity of refrigerant flow distribution in eachinternal machine is improved, the refrigeration efficiency of the air conditioner is greatly improved, and the power consumption of a system is reduced. The supercooling device has simple structure and convenient installation, and contributes to providing a more stable and uniform refrigeration effect.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner supercooling device and an air conditioner. Background technique [0002] In modern life, air conditioners have become one of the more popular household appliances. There are many forms of air conditioners. For example, small one-to-one air-conditioning systems are often used in small spaces such as family homes. Multi-connected air-conditioning units are generally used in places with larger spaces, such as large shopping malls, office buildings, hotels, etc., to facilitate centralized control. [0003] Taking the multi-connected air conditioner as an example, in the existing multi-connected air conditioner system, due to the large number of indoor units connected to the outdoor unit, the refrigerant output from the condenser needs to be distributed to different indoor units through multiple pipes, so that the refrigerant in the condenser The pressure...
