Abstract

The method for automatically-changing cold / warm operation mode of air conditioner includes three stages of automatic operation selection stage, automatic operation actuating stage and operation mode change stage. The automatic operation selection stage; before said cold / warm air conditioner is started or when the operation mode is set by user, according to the selection of user it can be converted to the stage of automatic operation mode; automatic operation actuating stage; according to the selection of automatic selection stage at the same time of starting automatic operation mode indoor temp. is measured, if it is higher than / less than reference temp. in a certain range, it can be automatically changed to the refrigeration / heating operation mode; and the operation mode change stage: in the course of automatic operation stage the indoor temp. is measured.

Description

technical field [0001] The invention relates to a method for automatic operation switching mode of an air conditioner, in particular to a method for automatically switching to a cooling operation mode or a heating operation mode according to the measured temperature during the operation of a cold / warm air conditioner by testing the indoor temperature. Background technique [0002] Under normal circumstances, the purpose of installing an air conditioner is to use heaters, coolers, air purifiers and other equipment to heat, cool, and purify indoor air, creating a more comfortable indoor environment for users. [0003] figure 1 It is a structural diagram of a general refrigeration cycle equipment. The refrigeration cycle equipment is composed of a compressor 1, a condenser 2, an expansion mechanism 3, and an evaporator 4, and each component is connected by a refrigerant pipeline. The low-temperature and low-pressure gaseous refrigerant becomes a high-temperature and high-pres...
