No. 1 adjust the temperature. When the central air conditioner is turned on for heating, 20 degrees Celsius is a more comfortable temperature. When the air conditioner is turned down by 1~2 degrees Celsius, it can save electricity by about 10%. This slight change does not affect human comfort, but is conducive to reducing electricity bills.
No.2 regulates the expansion of air at the air outlet and contraction of air at the air outlet, so that warm air expands relatively, with large intermolecular gap, low density and light weight; On the contrary, the density of cold air drops sharply. The cold air in the room is originally below, and the air outlet blows the hot air below, because the density of hot air is smaller than that of cold air, which can speed up the exchange of cold and heat and make the overall temperature of the room rise rapidly. When the room temperature reaches the temperature set by the air conditioner, the compressor only needs a little electricity to maintain its work, and naturally it does not need electricity.
No.3 pay attention to the auxiliary heating with electricity. Pressing the "electric auxiliary heating" or "auxiliary heating" button on the air conditioner remote control will not assist heating. CCTV Life Tips did an experiment: two air conditioners, one with electric auxiliary heating function and the other without, raised the room temperature from 15 degrees Celsius to 20 degrees Celsius and kept it at 20 degrees Celsius for two hours.
At the beginning of the experiment, the electric auxiliary air conditioner was turned on, and the power soared from 10 watt to 300 watt, and finally reached 2000 watt! After the whole experiment, the power consumption of turning on electric auxiliary heating is about 30% higher than that of not turning on. In fact, this is because when the outdoor temperature is below MINUS 7 degrees Celsius and the compressor can't work, the auxiliary heating function is forced to be turned on. The auxiliary electric heater itself is an independent resistance wire, which can drive the air-conditioning compressor to start at zero degrees Celsius, and the power must be very high.
Power saving method of central air conditioning
1, wind speed setting: setting an appropriate wind speed can reduce energy consumption and noise. For example, setting a high wind speed at startup, controlling the temperature at the fastest speed, and then changing to a low wind speed to keep the indoor temperature unchanged can also achieve the purpose of saving electricity.
2. The connecting pipe should not be too long: the connecting copper pipe between the indoor unit and the outdoor unit of the central air conditioner should not exceed the recommended length as far as possible, and nothing can block the heat dissipation place of the outdoor unit, which can enhance the heating effect of the central air conditioner.
3. Regular cleaning and maintenance: It is recommended to clean the indoor filter once a month during the peak period, which can reduce the air conditioning load and be more hygienic. However, generally speaking, air conditioning and heating consume more electricity than refrigeration. Electrical appliances such as air conditioners are bought to serve us. For the sake of health, should I turn on the air conditioner or turn it on ~
