Air conditioning is an indispensable household appliance in daily life. Whether it is cooling in summer or heating in winter, it is of great use. So in the hot and humid summer, how can we use air conditioning to dehumidify? What does air conditioning dehumidification mean? How many degrees is the dehumidification of the air conditioner appropriate?
There are two general air indicators: one is temperature and the other is humidity. Dehumidification is the proportion of moisture contained in the air. If it is like Huangmei, the temperature is not very high, but the humidity is very high, and people feel that wet sweat can not come out. At this time, another function of the air conditioner appears, which can play the role of dehumidification, and the dry air makes people refreshing.
In summer, the humidity in the air is very high, especially after rain and muggy weather. The suitable humidity for the human body is about 60-70%. If the humidity is too high, the human body will feel uncomfortable. At this time, if the air conditioner is turned on, the water vapor in the air will adhere to the low temperature of the air conditioner evaporator and condense into dew, which will be discharged outdoors through the water collecting tray and pipeline, so the air conditioner will play the effect of dehumidification at the same time in the refrigeration process.
The 'dehumidification mode' of the air conditioner is to make the whole air conditioner in the dehumidification operation state. At this time, the fan of the indoor unit runs very slowly, which is to facilitate the condensation of water vapor in the air into liquid. Generally, when the air conditioner reaches the set temperature in the dehumidification mode, the outdoor machine will stop running to prevent the dew on the condenser from evaporating again.
Air conditioning dehumidification principle
The air conditioner has dehumidification function in two modes:
First, the independent dehumidification mode is called the dehumidification principle of constant temperature air conditioning by people in the industry. Its basic principle is to reheat the air cooled by the evaporator to the original temperature, and then send it indoors, so that the indoor environment remains relatively constant when the humidity decreases.
Second, refrigeration mode, which is the mode of any air conditioner, is also the most basic function of the air conditioner. The refrigeration process of the air conditioner must be accompanied by dehumidification. The temperature of the humid air will drop significantly after passing through the evaporator of the air conditioner. 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'. When the refrigeration mode reaches a certain equilibrium state, the air humidity will drop to a certain level.
When using the dehumidification mode of the air conditioner, it should be noted that if the outdoor temperature is very high and the air is very dry, do not turn on the dehumidification mode for a long time to avoid damaging the compressor. Generally, when the outdoor temperature is higher than 40 ℃, the ordinary refrigeration mode should be used for operation. Only in the evening with relatively low temperature and high humidity, The dehumidification mode can be opened in time to achieve the effect of adjusting the temperature and humidity of the room.
How many degrees of dehumidification of air conditioner is appropriate
1. Automatic setting of dehumidification temperature of air conditioner
At present, the temperature of most air conditioners during dehumidification is automatically set by the manufacturer. In the dehumidification mode, the control circuit will first check the room temperature and then set the target value of operating temperature. The set value in the manufacturer's design is generally that the target value reached by operation is 2 degrees lower than the room temperature. If it is set too high, the dehumidification effect is not obvious, and too low affects the room temperature. In order to avoid excessively lowering the room temperature during dehumidification, this setting value is generally locked. At this time, we don't need to set the temperature. Just turn on the dehumidification function of the air conditioner.
2. Manual setting of dehumidification temperature of air conditioner
For air conditioners that need to set their own dehumidification temperature, there is no special research on this problem in the field. According to the experience of the majority of netizens, it is most appropriate to set the temperature at 4 degrees lower than the room temperature. For example, if your refrigeration temperature is set at 27 degrees, it is best to set the dehumidification temperature to 23 degrees.
Precautions for dehumidification of air conditioner
When using the dehumidification mode of the air conditioner, it should be noted that if the outdoor temperature is very high and the air is very dry, do not turn on the dehumidification mode for a long time to avoid damaging the compressor. Generally, when the outdoor temperature is higher than 40 ℃, the ordinary refrigeration mode should be used for operation. Only in the evening when the temperature is relatively low and the humidity is high can the dehumidification mode be opened in time to achieve the effect of adjusting the room temperature and humidity.
How many degrees does the dehumidification temperature of the air conditioner open? Generally, most of the dehumidification modes of the air conditioner are automatic mode and do not need to be set by yourself. If you need to set it by yourself, it is more appropriate to set it at about 4 degrees lower than the room temperature. However, if the air conditioning dehumidification mode is used for a long time, the air conditioning compressor will be damaged. Generally, it can be used for 1-2 hours at a time.
That's all about what air conditioning dehumidification means and how many degrees air conditioning dehumidification is on. I hope it will be helpful to you!
