Is it useful to turn on the air conditioner in wet weather? Is it useful to turn on the air conditioner in humid weather, Zhihu?

There has been a lot of rain recently and the air humidity is high. In China, resurgence often occurs. Even the floor and walls are wet, and the clothes can't be finished. I wonder if turning on the air conditioner can alleviate the indoor humidity in damp weather?

Is it useful to turn on the air conditioner in wet weather?

Useful.

The air conditioner has dehumidification function. Use the "Dehumidification Mode" in the remote controller, press the key to turn on the dehumidification function, and the remote controller displays the figure of water droplets as dehumidification. This function can reduce the indoor relative humidity by liquefying the water vapor in the indoor air into condensed water and discharging it outside.

Dehumidification principle of air conditioning

When the refrigerant in the evaporator of air conditioner evaporates, it will absorb a lot of heat to reduce the temperature of the evaporator surface, so that the water vapor in the indoor air will liquefy into water when it is cold, and these condensed water will flow to the water receiving tray and be discharged outdoors through the water outlet pipe. This is the working principle that air conditioners can dehumidify.

Is the air conditioner cold or hot?

Turn on the cooling mode.

Air conditioning refrigeration dehumidification is in the process of refrigeration, press and hold the mode until the snowflake icon appears as refrigeration mode.

After the humid air passes through the evaporator of the air conditioner, the temperature will drop greatly and the air humidity will be in a supersaturated state. Excess water vapor will precipitate in the form of condensed water and condense on the fins of the evaporator, that is, "condensation". When the refrigeration mode reaches a certain equilibrium state, the air humidity will also drop to a certain level. In order to prevent the room temperature from being too low after dehumidification, the general air conditioner manufacturers will set the temperature about 2 degrees lower than the room temperature to prevent low temperature and dehumidify smoothly. Therefore, it is generally not necessary to use air conditioning to dehumidify when returning to the south.

How many degrees of air conditioning dehumidification is suitable for returning to Nantian?

Most air conditioners automatically set the temperature when the dehumidification function is turned on. If you have to set it yourself, it is best to set it at 4 degrees lower than the room temperature.

Independent dehumidification of air conditioner is to reheat the cooled air to the original temperature through evaporator and then send it indoors. The indoor fan keeps running at low speed, the compressor starts and stops, and the refrigeration system does intermittent refrigeration cycle. Most of the generated refrigeration capacity is used to balance the latent heat of indoor air, that is, water vapor becomes condensed water. A small part is used to balance sensible heat, that is, to lower some indoor temperatures. This continuous circulation keeps the room temperature near the set value and removes a lot of moisture in the air, so most air conditioners do not need to adjust the temperature for dehumidification.

How to dehumidify the air conditioner in Nantiankai?

1. Close the doors and windows facing south and southeast in advance to prevent moisture from blowing into the room with the south wind, so as not to aggravate the indoor moisture.

2. The air conditioner turns on the "dehumidification" mode to reduce the indoor air humidity.

3. If you need to cool the room while dehumidifying, you can set the temperature of the indoor unit of the air conditioner, adjust it to a suitable value, and run it in refrigeration mode.

4, air conditioning dehumidification will reduce the indoor air humidity, if people stay in an air-conditioned room for a long time, they will feel thirsty, you should remember to add more water.

5. The air conditioner dehumidifies by lowering the temperature. People catch colds easily at low temperatures. It is recommended that you don't turn it on for a long time, and only use it temporarily when the indoor humidity is serious.

How long does it take to dehumidify the air conditioner?

In the environment with high air humidity, it takes about three hours for air conditioning to dehumidify, and in general, it can achieve dehumidification effect in about one hour.

Because air conditioning dehumidification mainly absorbs heat, it will have a certain cooling effect after opening dehumidification mode. However, if the outdoor temperature is too high, you need to wait for a while before switching to refrigeration mode, and the night with relatively low temperature and high humidity is the best time to open dehumidification mode.

But if there is a dehumidifier at home, it will be more suitable for indoor dehumidification than air conditioning. This is because the dehumidifier not only has a large amount of dehumidification, but also does not reduce the indoor temperature, which can avoid the increase of temperature difference and has a better effect than air conditioning.
