How much electricity does it cost to heat the air conditioner in an hour?
The following picture shows the power consumption of a 2-horse air conditioner when heating.

Below Zhao Yu calculates the parameters of 1-horse air conditioners for everyone to calculate how much electricity a 1-horse air conditioner will consume in one hour when heating. This is a single-cooled air conditioner with one horse. We can take a look at the machine. This machine does not have the power when heating. In fact, the power of air conditioner cooling and heating is the same. In the absence of electrically assisted heat. So, can we determine that the electricity consumption of air conditioning, cooling and heating are the same? In fact, the power consumption is the same in terms of power alone. So, why do we feel that heating is more power-consuming? It's because. The heating efficiency of air conditioning is lower than cooling. At the same time, the efficiency of air conditioners is getting lower and lower as the outdoor temperature drops. The lower the outdoor temperature. The lower the heating efficiency of the air conditioner. It also consumes 1 kilowatt-hour of electricity and generates less heat.
Therefore, for ordinary air conditioners, in the winter when the temperature is too low, it is very difficult to refrigerate. Why does this happen? 1. In winter, the temperature in the north is minus 25 degrees Celsius. The indoor temperature must reach 25 degrees above zero. There is a temperature difference of 50 degrees. The air conditioner needs to overcome the temperature difference of 50 degrees, and it can be said that the conditions are very harsh. Therefore, it is difficult to heat an ordinary air conditioner without electric auxiliary heating. Then let’s take a look at the working conditions of air conditioning and cooling. For example, in the south, the outdoor temperature is 38 degrees. We set the indoor temperature by 25 degrees. Let's calculate that the temperature difference is only 13 degrees. Compared to heating, it is very small. Therefore, heating generates the same heat than cooling, which consumes more electricity. 2. When heating, the outdoor temperature is very low. When our air conditioner is turned on for a while, the outdoor unit will be frozen and cannot dissipate heat. We have to defrost the external unit. When the air conditioner is defrosted, the internal unit will be shut down. The external unit heats it to melt the ice layer. At this time, the air conditioner consumes power. But it doesn't blow hot air. So when heating, the air conditioner will turn and stop for a while. The lower the temperature, the longer the stop time. The lower the efficiency.
So how much electricity does it cost to heat an air conditioner in one hour?
Let’s calculate the above 1-horse air conditioner. Let’s look at the parameters and find out the machine’s: Rated cooling input power: 760W. That is, 0.76KW. means 0.76KWH in one hour. It is 0.76KWH. It is 0.76KWH. So do you think air conditioning is very cost-effective? Then we need to ignore one problem. It is the downtime of the air conditioner. And the temperature of the air. As the outdoor temperature drops, the downtime of the air conditioner's internal unit will be extended, which means that the air conditioner is consuming power, but the internal unit does not generate hot air. It is the defrost time. At the same time, when the temperature is too low, this air conditioner without electric auxiliary heat will not be very hot when the air outlet is exposed. Very inefficient. Therefore, this ordinary air conditioner without electric auxiliary heat cannot play a big role in places with relatively low temperatures. The heating is very slow, and the air outlet is not very hot. Therefore, in the north, you still need to choose variable frequency when using air conditioners in winter. Or professional low temperature machine. Ordinary air conditioners are difficult to meet the heating needs. At the same time, if you want to use air conditioner to heat it up.
In places with low temperatures, we choose air conditioners: 1. It must have electric auxiliary heat function, in the north. 2. Choose a frequency converter machine or a low-temperature machine. 3. Choose a slightly larger power.
