How does an indoor air conditioner regulate humidity? What is the best humidity for air conditioner

The method of adjusting the humidity of the indoor air conditioner is according to the instructions for the use of the air conditioner, in general, the adjustment of humidity, if the temperature is relatively humid, it can be set to the dehumidification mode of the air conditioner, that is, the mode of dehumidification. This allows the air to be drier.

The indoor air conditioner regulates the humidity according to the operating instructions of the air conditioner, usually the humidity, if the temperature is lower than the humidity, the humidification mode can be set in the air conditioner, that is, the dehumidification mode. This allows the air to dry.

In fact, air conditioning can only reduce indoor humidity, whether it is heating or cooling, or defrosting mode, it can effectively reduce indoor humidity, but cannot increase indoor humidity.

The air conditioner has a dehumidifying function, which can condense the moisture in the indoor air into water and discharge it to the outside.

The premise is that the indoor temperature is above 20 degrees. When the room temperature is below 20 degrees, the dehumidifying effect is reduced. When the room temperature is below 16 degrees, the dehumidifying function does not work. The dehumidification function of the air conditioner is based on the principle that the moisture in the air will be condensed into water when it is cold.

The air conditioner dehumidifies, and the heat exchanger of the indoor unit acts as an evaporator to absorb heat. When the air in the room is sucked in by the fan of the indoor unit and passes through the evaporator, the moisture in the air is condensed into water, and then flows into the drain pipe to be discharged outside, and part of the moisture in the air in the room is removed. The relative humidity of the air has dropped from more than 70% before dehumidification (the uncomfortable feeling on sauna days) to about 50%, giving people a dry and comfortable feeling, and getting rid of the discomfort of being wet before dehumidification.

In addition, the method of increasing indoor humidity is as follows: mop the floor at least twice a day with a clean wet mop, which can not only remove dust, but also increase the contact area between moisture and air, so that the moisture can evaporate quickly, which can effectively increase indoor air humidity. If it is a wooden floor, you can use a wrung out mop to mop the floor to prevent too much moisture from penetrating into the wooden floor, causing mold and rot.

1. You can put potted water in the house to increase the indoor humidity while the water evaporates.

2. Put a wet towel on the heating, the heating will carry moisture when dissipating, and it can also increase the humidity of the air.

3. The use of humidifiers in bedrooms and living rooms can quickly increase air humidity.

4. Putting some green potted plants indoors, such as pothos, spider plants, etc., can also regulate air humidity.

When setting the humidity in the air-conditioned room, the relative humidity that is more suitable for the human body is: when the room temperature is 25 in summer, the relative humidity is controlled at 40%-50% and is more comfortable; In winter, when the room temperature is 18, the relative humidity is controlled at 60%-70%.

The average person feels most comfortable at 45-55% relative humidity. The relative humidity in an overheated and unventilated room is generally low, and too high humidity affects the perspiration function of the person to regulate the body temperature, and the person will feel stuffy.

In general, people feel better in situations of high temperatures but low humidity (such as deserts) than in situations where the temperature is not too high but the humidity is high (such as rainforests).

Air indicators

There are two general air indicators: one is temperature, the other is humidity, dehumidification is to reduce the proportion of water contained in the air, if the temperature is not very high like Huangmeitian, but the humidity is very high, people feel that the sweat is wet, then another function of the air conditioner appears, it can play a role in dehumidification, and the dry air makes people refreshed.

When the humidity is set in the air-conditioned room, the relative humidity suitable for the human body is: when the room temperature is 25 in summer, the relative humidity is controlled at 40%-50% more comfortably; In winter, when the room temperature is 18, the relative humidity is controlled at 60%-70%. In general, people feel most comfortable when the relative humidity is 45-55%.

The relative humidity of overheated and unventilated rooms is generally low, and excessive humidity affects the perspiration function of human body temperature regulation, making people feel stuffy. In general, people feel better in high temperatures and low humidity (e.g., deserts) than in low temperatures and high humidity (e.g., rainforests).

1. Put basin water in the room.

This trick should be known to everyone, but if you have a humidifier at home, it is best to choose to use a humidifier to increase humidity, which will be more effective. If there is no humidifier, we have to use more water to wipe the floor, the evaporation of water vapor on the floor can also increase the moisture content in the air, which can not only relieve the dryness of indoor air, but also clean up, the best of both worlds.

2. Leave a gap in the door and window.

Many people feel thirsty and dry when they are in an air-conditioned room, but in fact, the human body is already seriously dehydrated at this time, so it is necessary to replenish the water lost by the body as soon as possible. Try not to close all the doors and windows, and leave a gap where the air can circulate so that the air is not too dry.

3. Don't leave the air conditioner on all night.

Although the weather is hot, it is best not to open all night, because if the humidity in the room is too low, it is very conducive to the invasion of bacteria, especially the respiratory tract, which means that many people will have a dry mouth after a night's sleep and feel that they have a cold, but in fact, it is likely that your respiratory infection is very high. If it's too hot, it's best to get up in the middle of the night and open the window for ventilation.

4. Put a wet towel on the heating, and the moisture can also increase the air humidity when the heating is dissipated. If possible, you can put a sink on the heater, the effect will be better. Putting a basin of water under the radiator can also increase the humidity of the air.

In addition, after taking a hot bath, the water vapor in the bathroom is heavy, and when you open the bathroom door, the humidity of the room will increase instantly. Keeping green plants can also help to maintain proper humidity in the room, especially ferns, and frequent foliage spraying with water can help improve the air humidity in the room.

1.Put a basin of water or wipe the floor in an air-conditioned room, and put a basin of cold water in the room before going to bed; Alternatively, wipe the entire room floor with a damp mop to increase the humidity of the air.

2.Raise some green aquatic plants such as Fugui bamboo and begonias in the room, or raise goldfish, and slowly evaporate the water to relieve the dryness of the air.

Air conditioner dehumidification is best set at 4 degrees below room temperature.

For example, if the temperature of refrigeration is set at 27 degrees, then it is best to set the dehumidification temperature to 23 degrees. Using the air conditioner dehumidification mode for a long time will damage the air conditioner compressor.

Generally, 1-2 hours at a time is fine.

Turning on the dehumidification mode for a long time will cause the indoor air to be dry and uncomfortable, and it will also consume more electricity, so it is not recommended to turn on the dehumidification mode for a long time, when the indoor humidity is reduced to a comfortable state. Then adjust to a different comfort mode.

Difference Between Refrigeration and Dehumidification:

The difference between the two is that air conditioning is aimed at reducing the temperature of the air, and at the same time, it can also remove water vapor.

The purpose of dehumidification is to remove water vapor, and at the same time, it can also achieve the effect of reducing the air temperature. When the air conditioner selects the refrigeration mode, the temperature and wind speed of the refrigeration can be adjusted, while in the dehumidification mode, the temperature and wind speed of the dehumidification are not adjustable.

In addition, in refrigeration mode, the air conditioner will manually select to reduce the temperature and remove condensate.

The cold wind it blows is relatively strong; In the dehumidification mode, the air conditioner automatically sets the low temperature and low wind speed to remove the water vapor in the air and blow out cold air, but it is relatively weak.

Refrigeration mode. 1. You can use a humidifier to turn on the air conditioner. Because the temperature is low in winter, the content of water vapor in the air is very small, when we inhale the air, the air is heated by the human body, and the humidity will become very low, so it will feel dry when the air conditioner is turned on frequently.

2. In addition, the air filtered by the human body exhales out of the body is basically saturated steam, which consumes a lot of water in the human body, and the surrounding air will also be heated, so it is easy to dry in winter.

3. The use of humidifiers in the environment of air conditioning can effectively improve the phenomenon of dryness. However, from a health point of view, humidifiers are not suitable for everyone, some elderly people and people with chronic respiratory diseases need to be cleaned before using humidifiers, otherwise the mold and other microorganisms in the humidifier enter the air and cause secondary pollution.

4. The time of opening the humidifier should be controlled accurately, and the comfortable humidity of the human body in winter is 50%, if the humidity is too high, it will cause chest tightness and difficulty breathing.

Precautions for turning on the air conditioner:

1. In summer, turn on the air conditioner and the wind direction is facing upward, because the cold air is heavier, it can realize top-down circulation and enhance the refrigeration effect. In summer, the most suitable temperature for air conditioning is 26 degrees, which is comfortable and will be too cold and cold, and the air conditioner at this temperature is more energy-saving. Before going to bed at night, the air conditioner should be set to turn off at a regular time, which can not only save electricity but also keep the room cool all night.

2. In winter, it is necessary to pay attention to setting a reasonable temperature when turning on the air conditioner, generally about 20 degrees, so as to avoid a cold caused by too large a temperature difference with the outdoors. In addition, in the hot air-conditioned room, you can pay attention to hydration, you can put a basin of water indoors, do not turn on the air conditioner for too long, and inject fresh air regularly to avoid bacteria breeding in the hot and humid air.
