What does the snowflake sign of air conditioner mean?

1, the air conditioner snowflake label is in cooling mode.

2. The meanings of various modes in air conditioning are:

(1) Snowflakes represent refrigeration.

(2) The sun stands for heating.

(3) water droplets represent dehumidification (even in rainy days, they can be used to remove indoor moisture)

(4) The fan stands for air supply (in this mode, the compressor does not work, only the indoor fan rotates).

(5) The triangle icon is in automatic mode.

3. The working principle of air conditioning

(1) air conditioners are divided into single-cooling air conditioners and dual-use air conditioners, and their working principles are the same. Freon used to be the common refrigerant in air conditioning. The characteristic of freon is that it releases a lot of heat when it changes from gas to liquid. When it changes from liquid to gas, it will absorb a lot of heat. That is, the air conditioner is designed according to this principle.

(2) The compressor compresses the gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant, then sends it to the condenser (outdoor unit) for heat dissipation, and then turns it into liquid refrigerant at normal temperature and high pressure, so the outdoor unit blows out hot air.

(3) Then enter the capillary and enter the evaporator (indoor unit). Because the space suddenly increases and the pressure decreases after the refrigerant reaches the evaporator from the capillary, the liquid refrigerant will vaporize and become a low-temperature gaseous refrigerant, thus absorbing a lot of heat.

(4) The evaporator will get cold, and the fan of the indoor unit will blow out the indoor air from the evaporator, so the indoor machine will blow out cold air; Water vapor in the air will condense into water droplets when it meets a cold evaporator and flow out along the water pipe, which is why air conditioners produce water.

(5) When heating, there is a component called the four-way valve, which makes the refrigerant flow in the condenser and evaporator in the opposite direction to that during refrigeration, so when heating, cold air is blown outdoors and hot air is blown indoors.

(6) In fact, it is the principle that we should expel heat when liquefying (from gas to liquid) and absorb heat when vaporizing (from liquid to gas).
