an air conditioner

Abstract

The invention discloses an air conditioner. The air conditioner comprises a main engine body, a panel covering the main engine body, a control unit arranged on the main engine body and a temperature sensing unit connected with the control unit. A temperature sensing switch is arranged between the temperature sensing unit and the control unit. Through arrangement of the temperature sensing switch, when filing is carried out on a refrigerant, the temperature sensing switch can be turned off, a temperature sensing line stops working, and the temperature of the temperature sensing line meets the starting requirement of the refrigerating mode; and at the moment, the refrigerating mode of the air conditioner is started, an outdoor unit is started, and is filled with the refrigerant, and after filling of the refrigerant is completed, the temperature sensing switch is started, and the temperature sensing line is controlled to be returned to work. The manner is adopted for filling of the refrigerant, all components of the air conditioner are not required to be dismounted, and operation is convenient; the temperature of the temperature sensing line can be adjusted only through connection and disconnection of the temperature sensing switch; and the air conditioner is easy and convenient, time and labor are saved, the filling efficiency is improved, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of production and manufacture of air conditioners, and in particular relates to an air conditioner. Background technique [0002] Refrigerants, also known as refrigerants, are commonly known as refrigerants in some areas in the south. It is a working substance that circulates continuously in the refrigeration system and achieves refrigeration through its own state changes. The refrigerant absorbs the heat of the cooled medium (water or air, etc.) in the evaporator and evaporates, and transfers the heat to the surrounding air or water in the condenser to condense. [0003] Due to the inevitable loss of refrigerant circulating in the air conditioner, there will be insufficient phenomenon, so it is necessary to add refrigerant to the air conditioner. The air conditioner needs to be filled with refrigerant in the cooling state of the air conditioner. In spring, autumn and winter, especially in winter, the air ...

AI Technical Summary

Problems solved by technology

The air conditioner needs to be filled with refrigerant in the cooling state of the air conditioner. In spring, autumn and winter, especially in winter, the air conditioner cannot start cooling normally because the ambient temperature is relatively low and is lower than the start-up temperature of the cooling mode. mode, the way of adding refrigerant is more complicated

[0004] It is troublesome to add refrigerant in the traditional way. First, the air conditioner needs to turn on the cooling mode, such as figure 1 As shown, you need to remove the panel 13 first, then remove the filter 12, take off the temperature sensing line (thermistor) 14 and hold it in the palm of your hand, use the temperature of the palm to heat it (or soak it in warm water at about 30° ), so that the temperature-sensing line is heated to the cooling start-up condition, the external unit is started, and the refrigerant can be filled at this time, but such an operation needs to be completed until the refrigerant is filled. wire (thermistor) to make it heated, which is more troublesome, and the time and labor costs are greatly increased
