The air conditioner turns on the dehumidification mode, which not only saves electricity but also comfortably.Is this really the case? I wanted to be more serious today, so I bought an electricity meter to test it.
Does dehumidifying the air conditioner really save electricity?
The initial temperature in the room is 34 degrees, and the cooling and dehumidification modes are turned on for one hour, and the power consumption is as follows
The power consumption is similar, and the dehumidification mode is slightly higher. This is actually to be expected:The essence of dehumidification mode is refrigeration. When we use air conditioners for refrigeration, condensate also flows out. This is due to the low surface temperature of the evaporator and the condensation of water vapor in the air when it encounters the evaporator.
The dehumidification mode accelerates the generation of condensate by reducing the surface temperature of the evaporator and reducing the air volume. There is less water vapor in the room, and naturally it becomes drier.
In other words, the refrigeration mode will also dehumidify, but it is less efficient; The dehumidification mode also cools down, but at a slower rateAt a room temperature of 34 degrees, the temperature drops to 25 when the refrigeration mode is turned on for 30 minutes; And turned on the dehumidification mode, waited for 40 minutes, and then dropped to 25
Power saving", but what about comfort? Is it really more comfortable to turn on the dehumidification mode than the refrigeration mode?
Today, the air humidity in my house is 50%, and after turning on the dehumidification for 1 hour, I don't feel very good. His nose was dry and painful, and his throat was slightly hoarse. **It feels like it's about to crack, and the driest autumn hasn't been so bad.On the contrary, the cooling mode is much better, although the air humidity also decreases after 1 hour of activation, but there is no obvious discomfort.
Of course, this feeling is more subjective, and different people and different regions may have different feelings. ButThe overall feeling in dehumidification mode is certainly no better than in refrigeration mode.
For this reason, I also consulted a friend who sells air conditioners, and she said that the dehumidification mode is aimed at"Sauna day".。When the air exceeds 70% and the air temperature does not drop below 35, it will be more comfortable to turn on the dehumidification mode.
How to use air conditioner to save more electricity?
People who love the dehumidification mode are probably all to save electricity. Since the dehumidification mode does not save electricity, is there a way to save electricity? Yes – and more.
Method 1 The correct way to set it up
When an air conditioner is cooling, the 3 main factors that affect the power consumption are:
TemperatureThe higher the set temperature, the lower the power consumption. Some people say that "26 is the most power-efficient", which is obviously wrong. I also did a test, and 26 ran for 1 hour, and the power consumption was significantly higher than 30 for 1 hour.
If you want to save power, set the temperature of your air conditioner to the highest temperature you can accept.
Outlet angleThe most energy-saving way is to automatically wind the direction, that is, to make the wind deflector swing. This speeds up indoor air circulation, cools the room quickly, and allows the air conditioner to shut down earlier to save power.
If you can't accept the swing of the wind deflector (afraid of direct blowing), you can set the wind deflector to the highest position and blow towards the ceiling.
Wind speedIf you want to save power, adjust the wind speed to the maximum. The large air volume can also accelerate the indoor air circulation, so that the room can be cooled down quickly, so as to achieve the purpose of saving electricity.
Method 2 Use with other products
When used in conjunction with other products, it can also reduce the power consumption of air conditioners. Here are two examples:
Electric fan——The air blown by the fan is conducive to speeding up the indoor air circulation, which can not only make the room temperature more balanced, but also help the room cool down quickly, so that the air conditioner can be shut down earlier to save electricity.
In addition, when an electric fan blows on a person, it will also make people feel cool. In this way, even if the temperature of the air conditioner is turned up to 30, it will not feel hot, and you can avoid getting air conditioning disease.
Fresh air system——The biggest problem encountered by turning on the air conditioner is that it cannot be ventilated, and occasionally opening the window to breathe in will cause the power consumption to surge. The fresh air system can replace the window opening to complete the ventilation work.
In addition, the fresh air system also has a "heat exchange" function. While ventilating, the indoor temperature can be kept constant. By the way, you can also filter the outdoor air to prevent the onset of allergies and other diseases.
