How about turning on the air conditioner at 27 degrees in summer? How many degrees does the air conditioner turn on to save electricity?

The set temperature of the air conditioner is not lower than 27 degrees Celsius, which is more energy-saving than the set temperature is lower than 27 degrees Celsius. I used to work as a project manager in a hotel, because I did energy consumption statistics every month. Therefore, by comparison, if a guest sets the temperature to 18 degrees Celsius for one night in summer, the energy consumption is about 15-20 yuan. If the guest sets the air-conditioning temperature above 27 degrees, the energy consumption of air-conditioning is about from 8 yuan to 10 yuan. I have two air conditioners at home, the one in the living room is a cabinet inverter air conditioner, and the one in the bedroom is dead. If I set the air-conditioning temperature at 18 degrees, basically the air-conditioning compressor will not stop working, but if I set the air-conditioning temperature above 27 degrees, the air-conditioning compressor will stop working after working for more than ten minutes. What is the reason? In fact, the reason is very simple. The outdoor temperature is 40 degrees, and the indoor temperature is set above 27 degrees. The temperature difference between them is 13 degrees Celsius. If the indoor temperature is set to 18 degrees Celsius, the greater the temperature difference, the greater the air conditioning load, and the higher the air conditioning load. This truth is actually very simple. If the air conditioning temperature is set at 18 degrees Celsius for a long time, take the air conditioning in my bedroom as an example. I set the temperature at 28 degrees Celsius, and the compressor will stop working outside for more than ten minutes, and then restart for a few minutes after about half an hour. When I set the air conditioning temperature to 20 degrees Celsius, the compressor will keep working for a long time, even for a few minutes. When the compressor works for a long time, it will consume a lot of electricity and shorten the service life of the air conditioner. Therefore, it is recommended not to set the air conditioning temperature too low and not to use it in winter. In winter, some people set the air-conditioning temperature above 30 degrees Celsius, resulting in a large temperature difference between indoor and outdoor, freezing outdoor air-conditioning, and even burning out the compressor. Relationship between air conditioning temperature setting and power consumption 1. The lower the air conditioning temperature setting in summer, the greater the difference between air conditioning temperature and outdoor temperature. The greater the temperature difference, the longer the working time of the compressor, and the compressor will work for a long time. Will lead to an increase in power consumption. Formula power consumption = indoor and outdoor temperature difference = compressor working time. Therefore, the indoor air conditioning temperature is set above 27 degrees Celsius, which reduces the indoor and outdoor temperature difference = shortens the working time of the compressor = reduces the power consumption. Second, the small coup of air conditioning energy saving After one year of air conditioning use, it is necessary to clean the filter, which will help the air conditioner to blow out more wind and reduce energy consumption. Clean the air conditioning filter. After hanging up, usually after turning off the power supply, uncover the panel, take out the filter screen, then rinse it with clear water and drain it, and then install the filter screen in the air conditioner in sequence. It is easier to clean the filter screen of the cabinet machine. After turning off the power supply, there are three outer slots on the right side when standing facing the cabinet machine. This is the handle of the filter. You can pull it out, clean it and put it back. Third, the use of air conditioning tips on rainy days and humid weather, you can set the air conditioner to dehumidification, which saves more electricity. Don't set the air conditioning temperature above 30 degrees in winter to prevent the compressor from burning down due to long-term work. Setting the air conditioning temperature at 27 degrees Celsius in summer is more energy-saving than setting it below 27 degrees Celsius, because the temperature difference with the outdoor is reduced and the working time of the compressor is reduced, so it is more energy-saving.
