What is the difference between dehumidification and refrigeration of an air conditioner?

The lower the room temperature, the longer the evaporator surface is at a low temperature, which can achieve the purpose of power saving. But if the room temperature is too high, it won't work. It doesn't take long for the evaporator to heat up, causing the compressor to start up frequently or stop at all.

Frequent starts and non-stop are taboo for compressors. At this time, not only will the power consumption be doubled, but life will also be greatly affected. 2.

Comfort issues: Temperature-wise, if it's hot, the dehumidification mode can be "inadequate". Even if the air conditioner is turned on at the time, the temperature in the room will not drop – this is because in dehumidification mode, if the air is not blown, the room will not cool down as fast as the room will heat up.

From a somatosensory point of view, it's good that the dehumidification mode doesn't blow wind, but the dehumidification is harder. In refrigeration mode, the surface temperature of the evaporator is not kept to a minimum all the time, so the dehumidification mode dehumidifies better than the refrigeration mode. Sleeping in an air-conditioned room in refrigeration mode will make you feel thirsty, let alone dehumidification mode?

What we need is not dehumidification, instead, we need to use equipment such as humidifiers to increase indoor humidity. Bottom line: Whether or not to replace refrigeration with dehumidification mode depends on room temperature (or outdoor temperature).

When the temperature does not exceed 30 °C, the dehumidification mode is more suitable than the refrigeration mode. When the temperature exceeds 35, try not to use the dehumidification mode; Between 30 and 35, the experience is similar for both dehumidification and refrigeration modes.

What is the difference between air conditioner dehumidification and refrigeration? There are many functions of air conditioning, which is why people like air conditioning, after we install air conditioning, the main function is generally cooling and heating, and we most commonly use the refrigeration and dehumidification mode in air conditioning, so let's lead you to understand.

The difference between air conditioning dehumidification and refrigeration - the working principle of air conditioning dehumidification and refrigeration.

Refrigeration: The refrigerant is vaporized in the indoor evaporator of the air conditioner to remove the heat, so that the indoor air flowing through the evaporator heat sink is cooled. The vaporized refrigerant is compressed and liquefied by the compressor to release heat outdoors and transfer the heat to the outdoor air through the heat sink.

In this way, the continuous circulation achieves the effect of indoor air cooling.

Dehumidification: In the process of refrigeration, the temperature of the humid air will drop greatly after passing through the air conditioner evaporator, the air humidity is in a supersaturated state, and the excess water vapor is precipitated in the form of condensate and condensed on the fins of the evaporator, that is, "condensation", and when the refrigeration mode reaches a certain equilibrium state, the air humidity will be reduced to a certain level.

Difference Between Air Conditioner Dehumidification and Refrigeration.

1. The air conditioner runs in the refrigeration mode, and the water vapor must be removed at the same time while reducing the air temperature; Select the refrigeration mode, and the temperature and air speed of the refrigeration can be adjusted up or down. The air conditioner operates in refrigeration mode according to the artificially selected temperature and wind speed to achieve the purpose of reducing the air temperature (and at the same time discharging condensate), and the cold air blowing is relatively strong.

2. When the air conditioner runs in dehumidification mode, it is necessary to reduce the air temperature at the same time while removing water vapor; Select the dehumidification mode, and the dehumidification temperature and wind speed cannot be adjusted up or down. The air conditioner operates in dehumidification mode according to the automatically set low temperature and low wind speed to achieve the purpose of removing water vapor in the air (blowing out cold air at the same time), and the cold air blown out is relatively weak and soft.

3. The dehumidification function of the air conditioner is relative to the refrigeration function, the fan has been running at a low speed, the compressor is turned on and off, and the refrigeration system has an intermittent refrigeration cycle, and most of the refrigeration capacity generated is used to balance the latent heat of the indoor air, that is, the water vapor becomes condensate.

The air conditioner consumes a lot of electricity when it is running in the dehumidification state.

The lower the temperature setting during dehumidification, the better the dehumidification effect, and the power consumption is proportional. Set up the dehumidification function, the reversing valve of the compressor system needs to be constantly reversed, refrigeration for a while, heating for a while so as to keep the room temperature unchanged, so the compressor is non-stop, which consumes more electricity. How often should the refrigerant of the air conditioner be added.

If one of the following situations occurs in the air conditioner, it is necessary to consider adding refrigerant (refrigerant).

1. The refrigeration effect is not good, and the temperature of the air outlet is not cold enough;

2. When the refrigeration is running, the connecting pipe of the outdoor unit is frosted;

3. Work for a long time without stopping and the cooling (or heating) effect is not good; If the faulty refrigeration system is initially judged to be insufficient refrigerant, please arrange professional service personnel to come to the door as soon as possible to check whether the pressure value of the air-conditioning and refrigeration system is insufficient or there is a leakage of refrigerant. Drip tube dripping speed is slow or not dripping at all, system pressure is too low, etc. In general, the refrigerant can be used for at least 3 years and at most more than 5 years.

The difference between dehumidification and refrigeration: different functions, different controls.

First, the functions are different:

Dehumidification is also the process of refrigeration, the humidity of the air condensed into water, to achieve the purpose of dehumidification, but the temperature is set higher during dehumidification, refrigeration is also intermittent, to avoid the temperature is too low to make people feel uncomfortable, so the required refrigeration power of dehumidification is relatively low, the special dehumidifier is also a small refrigeration equipment, the impact on the ambient temperature is relatively small.

Second, the control is different:

1. The temperature and wind speed of refrigeration can be adjusted up or down;

2. The temperature and wind speed of dehumidification should not be adjusted up or down.

Refrigeration principle. The compressor compresses the gaseous freon into a gaseous freon at high temperature and high pressure, and then sends it to the condenser (outdoor unit) to dissipate heat and becomes liquid freon at room temperature and high pressure, so the outdoor unit blows hot air.

The liquid freon enters the evaporator through the capillary, the space suddenly increases, the pressure decreases, the liquid freon will vaporize and become a gaseous low-temperature freon, thereby absorbing a large amount of heat, the evaporator will become cold, and the fan of the indoor unit will blow the indoor air through the evaporator, so the indoor unit blows out of the cold air; When the water vapor in the air meets the cold evaporator, it will condense into water droplets and flow out down the water pipe, which is why the air conditioner will produce water.

Dehumidification is also the process of refrigeration, the humidity of the air condensed into water, to achieve the purpose of dehumidification, but the temperature is set higher during dehumidification, refrigeration is also intermittent, to avoid the temperature is too low to make people feel uncomfortable, so the required refrigeration power of dehumidification is relatively low, the special dehumidifier is also a small refrigeration equipment, the impact on the ambient temperature is relatively small.

Refrigeration is to lower the temperature to make people feel cool, and dehumidification is to filter out the moisture in the air to make people feel dry.

Blowing an air conditioner in summer, do you know what is the difference between the dehumidification function and refrigeration function of the air conditioner?

Dehumidification is the removal of moisture from the house we are in by the force of the wind, while refrigeration is the reduction of the air in our room. I think it's better for us to use refrigeration in general.

3. Use different modes according to different situations. If the outdoor temperature is particularly high, the refrigeration mode should be used, and if the outdoor temperature is not particularly high and it is stuffy, the dehumidification mode is recommended, because the cooling effect in the dehumidification mode is not very good.

Dehumidification is to remove moisture in the house and keep the house dry, while refrigeration is to remove the heat in the house and reduce the temperature in the house.

Dehumidification is to change humidity, and refrigeration is to change temperature. Generally speaking, dehumidification is to reduce the moisture in the air, for example, on southerly windy days in the south, dehumidification is very necessary; And refrigeration is much simpler, the weather is too hot, turn on the air conditioner to cool down.

1. The effect is different

After the dehumidification effect of air conditioning is a simple change in the proportion of air moisture, and air conditioning and refrigeration are not limited to such an effect of refrigeration. In fact, most air conditioners will carry out continuous dehumidification at the same time when refrigerating, so people feel that the air conditioner not only drops the temperature when it is cooling, but also changes the indoor air humidity, and the air becomes drier. When the air conditioner is dehumidified, although it can also cool down to a certain extent, the cooling effect is not obvious.

2. The role is different

The function of air conditioner dehumidification is to make the indoor air dry and refreshing, while the cooling function of the air conditioner is to make the indoor temperature drop quickly and keep the indoor temperature cool. Therefore, to a certain extent, air conditioning dehumidification is an air conditioning function specifically for air humidity, and air conditioning refrigeration is a function for air temperature and its role is completed. The same thing is true for the same air conditioner, dehumidification and refrigeration that people feel differently.

1. Different modes:

When the air conditioner is in dehumidification mode, the indoor fan is running at a low windshield, and the compressor is running at full load; When the air conditioner is running in refrigeration mode, the speed and set temperature of the indoor fan motor are set and buried by the user.

2. Saving electricity is different

In dehumidification mode, the air conditioner is more power-efficient. In refrigeration mode, the air conditioner runs at high power, which consumes more electricity.

3. The working principle is different

In dehumidification mode, the hair dryer enters low-speed operation, driving the compressor to operate, which can ensure that the humidity in the room is constant.

In refrigeration mode, the compressor is running at full speed, which can quickly reduce the temperature in the room.

Actually, air conditioningRefrigeration modewithDehumidification modeThey are generally the same in terms of how they work, but they differ in some ways.

Let's start with thatRefrigeration modeThis mode is to compress the low-pressure vapor refrigerant, and the refrigerant is compressed into a liquid state under the action of high pressure, and vaporizes and absorbs a large amount of heat in the condenser, so that the outlet air temperature leakage decreases to achieve the effect of refrigeration. Refrigeration modeThe effect of the rock tremor fruit is generally very obvious, and some excellent air conditioners can reduce the indoor temperature in a short time.

And whereasDehumidification mode, the air conditioning will continueRefrigeration modeof heat circulation, but compared to ordinaryRefrigeration modeComponents such as internal compressors will remain running at low speeds. The evaporator in the air conditioner needs to absorb heat in the process of evaporating the jujube refrigerant, so that the overall temperature of the evaporator is reduced. In this case, the water vapor in the room will be condensed into liquid water when it encounters the low temperature evaporator, and then it will be discharged from the room.

InDehumidification mode, the user can feel that the air becomes drier and the temperature drops.

Therefore, no matter inRefrigeration modeUnder stillDehumidification mode, air conditioners will lower the indoor temperature, but the cooling speed is somewhat different. Comparatively, the cooling mode cools down a bit faster. But if you are in the rainy and muggy season, you can open itDehumidification modeto ensure a comfortable humidity in the room and also to ensure coolness.
