How to adjust the refrigeration of air conditioner?

Press "Mode" on the remote control until the snowflake icon appears, and you can adjust the cooling by adding or subtracting gears.

The snowflake icon is as follows:

Principle of air conditioning refrigeration

Household air conditioners generally use electric air conditioners powered by compressors. The refrigeration principle of this air conditioner is actually relatively simple. During the operation of the air conditioner, the compressor will suck in gaseous refrigerant, compress it into high temperature and high pressure gas, and then transport it to the condenser.

The high-temperature and high-pressure refrigerant in the condenser will become a low-temperature and high-pressure liquid after condensation, and then enter the evaporator after being reduced by capillary throttling. As the space becomes larger, the refrigerant will continue to absorb heat and evaporate. At this time, the inhaled air will be blown indoors after being cooled by the evaporator to realize refrigeration.

Extended data:

Air conditioning or air conditioning refers to the process of adjusting and controlling the temperature, humidity, cleanliness and speed of ambient air in buildings and structures by manual means.

Generally, it includes cold source, heat source equipment, cold and hot medium transmission and distribution system, terminal device and other auxiliary equipment. It mainly includes water pump, fan and pipeline system. The terminal equipment is responsible for using the cold heat from transmission and distribution to specially treat the air to make the air parameters of the target environment meet the requirements.

The four-way valve of air conditioner is a control valve with four oil ports. Four-way valve is an indispensable component in refrigeration equipment. Its working principle is that when the solenoid valve coil is in the power-off state, the pilot slide valve will move to the left driven by the right spring, and then the high-pressure gas will enter the capillary tube and the piston cavity at the right end, while the gas in the piston cavity at the left end of the other end will be exhausted.

There is a certain pressure difference between the two ends of the piston chamber. The piston and the main slide valve move to the left, so that the exhaust pipe is connected with the outdoor machine, and the other two connecting pipes are connected to form a refrigeration cycle.
