When using air conditioning for heating in winter, it is obvious that the electricity bill is rising rapidly. If you look carefully, it consumes more electricity than in summer! Why is this? Recently, I specifically asked some knowledgeable people, and then I understood the reason.
Why heating and air conditioning consume more electricity in winter
① Low efficiency
Air conditioning is essentially a heat transporter. In summer, it "cools" to transport excess indoor heat to the outdoors. Since the temperature difference between indoor and outdoor is not particularly large, it is easier to transport.
"Heating" in winter is to transport outdoor heat back indoors, but the outdoor temperature itself is relatively low in winter. Especially in northern cities, the outdoor temperature is several degrees below zero in winter. It is difficult to transport heat, and defrosting is required from time to time. It takes a long time and is bound to increase energy consumption.
② Large temperature difference
In order to save electricity in summer, the air conditioner temperature is usually set at 26-28 degrees, and the difference from the outdoor temperature is only a few dozen degrees at most.
In winter, the indoor temperature is generally set at 28-30 degrees during heating, and the temperature difference between and the outdoor temperature is as high as more than 20 degrees. The greater the temperature difference, the longer the air conditioner will work, and the higher the power consumption will naturally be.
③ Electric auxiliary heating
Nowadays, most air conditioners have electric auxiliary heating function. After is turned on, the working principle is similar to that of electric heater . It directly converts electrical energy into thermal energy to blow hot air. Although the heating efficiency is improved, it also increases power consumption, and the longer it is used, the more power it consumes.
How to use air conditioners to save energy in winter
. Unless absolutely necessary, try not to turn on the electric auxiliary heating function.
. The indoor set temperature should not be too high. Just keep it around 25-26 degrees. This can reduce the temperature difference between indoor and outdoor as much as possible, relieve the operating pressure of air conditioning and reduce energy consumption.
, The air outlet blows downward. Because the hot air has a light specific gravity, downward blowing can improve the circulation of hot air, quickly heat up the room, and save energy.
, There is no need to turn off the air conditioner when going out for a short period of time to avoid frequent switching on and off, which increases the loss of the air conditioner.
5. After using the air conditioner for 2 hours, remember to open the windows for ventilation to reduce indoor carbon dioxide and harmful gases, increase indoor humidity, and enhance comfort.
6. If necessary, it can be equipped with electric heating equipment to heat the room quickly and reduce the running time of the air conditioner.
