Why is there water dripping from the indoor air outlet when the air conditioner is cooling?

Usually a small amount is condensed water, that’s fine. If there are more, it is caused by leakage caused by the water receiving pan of the internal unit coming into contact with the condenser. A lack of refrigerant in the air conditioner may also cause water leakage.

Air conditioners are also called air conditioners.

Air conditioning is a device that processes the temperature, humidity, purity, and air flow speed of the air to meet people's production and living needs. It is referred to as "air conditioning" for short.

Air conditioner is an air conditioner (room air conditioner), which regulates temperature and humidity. A hanging air conditioner is a unit used to provide a space area (usually a closed one) to handle changes in air temperature. Its function is to adjust the temperature, humidity, cleanliness, air flow rate and other parameters of the air in the room (or enclosed space or area) to meet the requirements of human comfort or process.

Air conditioners are divided into single-cooling air conditioners and dual-purpose heating and cooling air conditioners. The working principles are the same. The refrigerant generally used in air conditioners is Freon. The characteristic of Freon is that when it changes from gaseous state to liquid state, it releases a lot of heat. When it changes from liquid to gas, it absorbs a lot of heat. Air conditioners are designed based on this principle.

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

Then it goes to the capillary tube and enters the evaporator (indoor unit). Since the space of the refrigerant suddenly increases after reaching the evaporator from the capillary tube and the pressure decreases, the liquid refrigerant will vaporize and become a gaseous low-temperature The refrigerant absorbs a large amount of heat, and the evaporator will become cold. The fan of the indoor unit blows the indoor air through the evaporator, so the indoor unit blows out cold air; the water vapor in the air evaporates when it encounters cold After the air conditioner is installed, it will condense into water droplets and flow out along the water pipes. This is why the air conditioner will produce water.

When heating, there is a component called a four-way valve, which causes the refrigerant to flow in the condenser and evaporator in the opposite direction to that during cooling. Therefore, when heating, cold air blows outside and the indoor unit It was blowing hot air.

In fact, it is based on the principles learned in junior high school physics of discharging heat when liquefying (changing from gas to liquid) and absorbing heat when vaporizing (changing from liquid to gas).
