Sihaiwang: it's hot in summer. People like to stay in an air-conditioned room all the time. But we all know that air conditioning costs a lot of electricity. In summer, if you need to turn on the air conditioner for a long time, you can't afford to pay for electricity. Then, many people will ask, how much electricity does the air conditioner charge for a night in summer? Let's take a look at it with Xiaobian~
How many degrees of electricity does air conditioning have in a night in summer
There is no certainty about this. It depends on the specific situation. The power consumption of the air conditioner is not only related to the power of the air conditioner, but also to the size of the room area and the quality of the sealed insulation conditions. It is also related to the outdoor environment temperature and the indoor temperature regulation.
1. The lower the outside air temperature, the less power consumption of the air conditioner.
2. The cooling capacity of the air conditioner is the same, the smaller the input power is, the more power is saved. The higher the power is, the more electricity will be consumed.
3. The smaller the area of the room, the better the sealing and thermal insulation conditions, the more power saving. The electricity consumption of 20 square meters is different from that of 10 square meters.
4. The top floor of the room or the west sun is more expensive.
5. In summer, the higher the indoor temperature is regulated, the more power is saved, and the lower the temperature is, the more power is consumed. 26 degrees saves electricity than 25 degrees, but 27 degrees costs electricity. When air conditioning is used for cooling, the power consumption will increase by about 5-8% when the indoor temperature is lowered by one degree.
6. Air conditioning does not clean for a long time, there is a lot of dust, air conditioning is prone to failure, but also increase the power consumption.
Give an example:
On the market, the cooling capacity of one HP air conditioner is about 2300-2500w. One hour power consumption is about 0.7-0.8 degrees. If you turn on the air conditioner for one night, at least for about 10 hours, it's estimated to be about 10 kilowatt hours. If the price is 0.53 yuan per kilowatt hour, the electricity charge for one night is at least 5 or 6 yuan.
However, you have to consider a situation, air conditioning has a 'on-off ratio' problem. Because the air conditioner is not running all the time, when the room reaches the specified temperature, the air conditioner compressor will stop working automatically, and then the air conditioner is not running at full power. At this time, only the indoor fans are working, and the power consumption is very small compared with the power consumption of the whole air conditioner, which can be 'ignored'.
That is to say, for example, after your air conditioner reaches the set temperature, it works for ten minutes after it stops, and then it stops again. Then the on-off ratio is 1:1. If it is calculated by one hour, it only works for 30 minutes. If the power consumption of one hour is 0.8 degrees, then it is two hours. So, if you turn on the air conditioner for about 10 hours, the minimum power of the air conditioner should be about 5 degrees per night, about 4 yuan.
What does air conditioning mean
The horsepower of air conditioner originally refers to the input power. The larger the horsepower, the better the refrigeration. Generally speaking, a 'horse' refers to a refrigerating capacity of 2300-2500w. The input power is about 800W.
Horsepower is a unit of power, 'horse' is a 'colloquial common name' of horsepower. Colloquially, it is usually called 'x horsepower'. 1 (horse) horsepower = 735 watts; 'Mach' is a unit of speed, which is usually used in military (fighter, missile and other high-speed aircraft) and Aerodynamics (there has never been a saying that the speed of 'XX car is YY Mach'). 1 mach is one times the speed of sound, 340 m / s.
Generally speaking, the air conditioning power and room area are as follows: 1-12 square meters, 1.5-18 square meters, 2-28 square meters, 2.5-40 square meters, 3-50 square meters, 5-70 square meters.
There is a ratio between the input power of the compressor and the refrigerating capacity, which is called COP value in the refrigeration specialty. The larger the value is, the higher the refrigerating capacity is when the input electric energy is certain. 2300 watt air conditioner refers to a 2300 watt cooling capacity, which is usually called a small machine, with a compressor power of about 750W. That is to say, the power consumption in an hour is about 0.7-0.8 degrees.
