How to improve the refrigeration temperature of air conditioner?

The steps are as follows:

1. The remote control is currently at Celsius, and the air conditioner is on now, as shown in the following figure:

2. First turn off the air conditioner, as shown in the following figure:

3. The air conditioner is turned off, as shown in the following figure:

4. Press the "Mode" and "-"keys at the same time, as shown in the following figure:

5. At this time, we have switched to Huaping, as shown in the following figure:

6. Press the "Mode" and "-"keys again to switch back, as shown in the following figure:

Principle of air conditioning refrigeration

Freon, so the outdoor unit blows out hot air. Liquid Freon enters the condenser (indoor unit) through the capillary, the space suddenly increases, the pressure decreases, and the liquid Freon will vaporize (from liquid to gas is an endothermic process), absorb a lot of heat, and condense and cool. The fan of the indoor unit blows out indoor air from the condenser, so the indoor unit blows out cold air;

The water vapor in the air will condense into water droplets when it meets the cold condenser and flow out along the water pipe, which is why the air conditioner will produce water. Then the gaseous freon returns to the compressor to continue the compression cycle. When heating, there is a component called four-way valve, which makes the flow direction of freon in condenser and evaporator opposite to that in refrigeration, so when heating, cold air is blown outdoors and hot air is blown indoors.

In fact, it uses the principle of expelling heat when liquefied (from gas to liquid) and absorbing heat when vaporized (from liquid to gas), and evaporates heat at the same time.
