Reading guide:It's July, and the temperature in the hot summer is even as high as 37 degrees or more, which is definitely the hottest time of the year, and with such a high temperature, sleeping at night without air conditioning is simply torture.
So, really thanks to the person who invented the air conditioner, it's hard to imagine the days before without air conditioning, how people slept at night on such a hot day?
Sleeping in an air-conditioned room at night is indeed a very enjoyable thing, but in fact, few people turn on the air conditioner all day and all night, the reason is the power consumption of the air conditioner, and some people even call the air conditioner "electric rat", which shows the large power consumption of the air conditioner.
So how much electricity does an air conditioner consume?What is the relationship with this?How can I save money on air conditioning electricity bills?With these questions, I consulted my cousin who opened a home appliance in the county, and after listening to my cousin's explanation, I suddenly realized.
1. Horse:When we buy air conditioners, we often hear the shopkeeper ask, "How many horses?""So what does a horse mean?The horse here is actually "P", which is the abbreviation of power, and the cooling capacity of 1P is about 2500W. 1.5p means that the cooling capacity is 15*2500w=3500w；2P means that the cooling capacity is 2*2500W=5000W, it can be said that the larger the number of horses, the stronger the cooling capacity.
2. Energy efficiency ratio:The energy efficiency ratio is the ratio of the rated cooling capacity to the rated power, the larger the better. After the official implementation of the new energy efficiency standards, the air conditioners on the market are basically new level and new. The new level is the best, but it is also the most expensive, generally more expensive than the new **, but it is more energy-saving than the latter, and now the energy efficiency signs of air conditioners have the parameter of "electricity consumption in the cooling season".
3. Rated refrigeration capacity:This is what we often call the number of horses, representing the refrigeration capacity of the air conditioner, the larger the number of horses, the stronger the refrigeration capacity, the rated cooling capacity of 1 horse air conditioner is about 2500w, 1The cooling capacity of 5 hp is about 3500W, and the cooling capacity of 2P is about 5000W.
4. Customized calories:The rated heating wattage, the maximum heating wattage is indicated in parentheses.
5. Refrigeration capacity:When the air conditioner is running for refrigeration, the heat absorbed by the refrigerant on the low pressure side in the evaporator per unit time is usually in W or kW.
Household air conditioners are generally wall-mounted air conditioners, and air conditioners are mostly 1-1 according to the different bedroom areas5P is the mainstay, for the sake of simplicity, here we use 1P wall-mounted air conditioner, which runs for 8 hours at night. The power of the 1P air conditioner is around 735W.
Calculation of power consumption of air conditioner: input power * running time 1000, then 735 * 8 1000 = 588 degrees, our local residents electricity is 06 degrees. That is to say, the electricity bill for an air conditioner is 35 yuan, a month of air conditioning costs only about 100 yuan, is it unexpected by many people?
If you use 1 in the bedroomIn the case of a 5P air conditioner, the cooling power is 1180W, and the power consumption is 1180 8 1000 944 kWh. The monthly electricity bill is 944×0.$6 30,169.
Less than 200 yuan a month can get a good night's sleep, I think that's why the popularity of air conditioning has been so high in recent years.
What factors are actually related to the power consumption of air conditioners, here are some of the main influencing factors, if you pay attention to these details in the use of air conditioners, you can completely save more electricity bills.
1. It is related to the power of the air conditioner.
The power of the air conditioner is the number of horses, the larger the number of horses, the greater the cooling capacity of the air conditioner, and the greater the corresponding power consumption, so under normal circumstances, 1-1A 5p air conditioner is enough for use in the bedroom, and there is no need to use a more powerful air conditioner, which is a waste of electricity.
2. It is related to the size of the bedroom
The larger the bedroom, the more air needs to be exchanged, and the more electricity will be consumed, so in fact, there are troubles with having a bedroom that is too large: the cost of air conditioning is too high.
3. It is related to the tightness of the room
If the bedroom is highly sealed, then the cold air will not easily flow outside the room, so the air conditioner will not work frequently, increasing the power consumption.
4. Outdoor temperature
Normally, the power consumption of air conditioners in winter is much higher than in summer, because the outdoor temperature in winter is below 0 degrees, and it needs to be consumed a lot of electricity to heat up to 26 degrees
In contrast, the temperature in summer is generally about 35 degrees, and the temperature difference between 26 degrees is only 10 degrees, and the electricity consumption is relatively small.
To sum up, the power consumption of the air conditioner is mainly related to the power of the air conditioner itself, the room area, the room sealing, the outdoor temperature difference and other factors.
As mentioned above, the power consumption of air conditioners is mainly related to 4 factors, if you want to save electricity, you can start from the following aspects.
1. Turn on sleep mode
When the air conditioner is running for refrigeration, you can choose the "sleep" function, the sleep mode can reduce the difference between the ambient temperature and the actual temperature, and the wind speed will automatically drop to prevent coldsAt the same time, the noise of the internal unit is also much smaller, which can generally save more than 20% of the power consumption.
2. Don't switch on and off often
Some people like to turn off the air conditioner when the room is cold, and then turn it on after the room is hot, they think that this can save electricity, but they don't know that the power of the air conditioner is the largest at the moment of turning on and off, which is much larger than the power consumption of normal operation, which is easy to cause waste.
So don't turn on and off often, turn it on to high and cold, and then the temperature drops down and then adjust it to medium and low level.
3. Close doors and windows.
As mentioned above, if the room is not well sealed, the air conditioner is easy to lose, which will lead to the non-stop operation of the air conditioner and increase the power consumption. Therefore, when we turn on the air conditioner, we must close the doors and windows to prevent the air outflow from increasing the burden of the air conditioner.
4. Clean the filter regularly
The long-term use of the air conditioner will accumulate a lot of dust on the filter screen, which will not only affect the air outlet and cooling efficiency of the air conditioner, increase the power consumption of the air conditioner, but also affect the air quality of the room. Therefore, it is generally necessary to clean up the dust once every 1-2 years, which can save a lot of electricity.
Many people may have a puzzle "how many degrees of power is the most energy-efficient when the air conditioner is on, in order to explain this secret, an engineer has done such an experiment."
Install a first-class energy consumption in a 20 square bedroom with an energy consumption of 15 hp inverter air conditioner, experiment with the power consumption of the air conditioner at different temperatures.
On Day 1, set the air conditioner temperature at 25, run 8, and the final power consumption count is 1681 degrees.
On Day 2, set the air conditioner temperature at 26, run 8, and the final power consumption count is 1161 degrees.
On day 3, set the air conditioner temperature at 27, run 8, and finally consume a power count of 1799 degrees.
From this, you can see that when the air conditioner temperature is set to 26 degrees, the power consumption is minimal, of course, due to different air conditioning parameters, the specific product shall prevail.
But in any case, it is obvious that setting the air conditioner temperature at 26 degrees is relatively power-saving, if you don't know how much you should set the air conditioner temperature, you can try to set it at 26 degrees, there is definitely a surprise.
In the hot summer, the air conditioner is simply our lifesaver, with it, we can have a high-quality sleep quality in the summer heat.
As for the electricity cost of air conditioning, in fact, there is no need to worry too much, because under normal circumstances, the cost of air conditioning for a month is only about 100-200 yuan, which is definitely affordable for the general public.
