Embodiment 1

[0017] as attached figure 1 As shown, the technical solution of the specific implementation of the present invention is to adopt a liquid storage tank 1 that can automatically adjust the capacity of the refrigerant in the air conditioner refrigerant circulation system, and the liquid storage tank 1 is used to store the excess in the refrigerant circulation system of the air conditioner. Refrigerant, liquid storage tank 1 is installed between the high pressure valve and throttling device of the refrigerant circulation system. The liquid storage tank 1 is composed of a closed tank body and an interface communicating with the bottom of the tank body, and the interface is connected between a high-pressure valve and a throttling device in the refrigerant circulation system.

[0018] A tee joint 2 is installed at the interface of the liquid storage tank 1 . One end of the three-way joint 2 is connected to the liquid storage tank 1, and the other two ends of the three-way joint are ...

Embodiment 2

[0027] Two pipe connections connected to the liquid storage tank are used to connect with the high-pressure valve and throttling device of the refrigerant circulation system respectively to form a liquid storage tank structure, reducing the setting of three-way joints, which is convenient for cost reduction and has the same effect.

[0028] The embodiment of the present invention has simple structure, convenient processing and manufacturing, and is easy to install, and can improve the cooling and heating effect of the air conditioner.

Abstract

The invention relates to a cooling medium circulation system of an air conditioner. A liquid storage tank is arranged between a high-pressure valve and a throttling device of the cooling medium circulation system of the air conditioner, when excess cooling medium is in the cooling medium circulation system of the air conditioner, the liquid storage tank is used for storing the cooling medium; when the cooling medium circulation system of the air conditioner internally needs the cooling medium, the cooling medium in the liquid storage tank can automatically return into the cooling medium circulation system. The liquid storage tank is vertically fixed with a condenser of the air conditioner into a whole through a fixing clamp and is connected with a port of a tee joint at a port of the bottom of the liquid storage tank, the other two ports of the tee joint are respectively connected with the high-pressure valve and the throttling device through pipelines, a tank body is made of metal materials or plastics, and the liquid storage tank is provided with a plane contacting with the condenser. The invention has convenient processing and manufacturing and easy installation and can improvethe cooling and heating effects of the air conditioner.

Description

technical field [0001] The invention discloses a refrigerant circulation system of an air conditioner, in particular to a liquid storage tank installed on an outdoor unit of the air conditioner and a method for automatically adjusting the amount of refrigerant in the refrigerant circulation system of the air conditioner by using the liquid storage tank. Background technique [0002] In the existing refrigeration or heating refrigerant circulation system of the air conditioner, it mainly includes a compressor, a high-pressure valve, a reversing valve, a condenser, a throttling device, an evaporator, a throttle valve, and finally a compressor connected in sequence through pipelines. Return to compressor. Since the circulation system is a closed circulation system, the total amount of refrigerant in the system will basically remain unchanged. For an air conditioner with two functions of cooling and heating at the same time, more refrigerant is needed in the refrigeration cycle...
