Does it cost electricity to turn on the air conditioner? /kloc-How much is the electricity charge for 0/2 hour a day?

Regarding whether air-conditioning heating needs electricity, my personal opinion is that air-conditioning heating needs electricity more than cooling. The reason why air conditioners consume electricity is determined by the working principle of air conditioners and the heating efficiency of air conditioners.

(a) the following specific performance. ①: The state of air conditioning heating is actually the reverse cycle process of air conditioning refrigeration. In this process, the power consumption required is much higher than that of air conditioning refrigeration. As we all know, air conditioning itself is mainly used for refrigeration. So its working principle is to cooperate with refrigeration. In the heating state, we need to consume electricity alone to provide the heat we need, which determines that heating needs more electricity than cooling.

②: For example, if we use a horse air conditioner at home, its input power is about 755 watts. If you look at the famous brand of air conditioner carefully, you will find that the input power of air conditioner is slightly higher in heating state. In addition, if electricity is applied to assist heating, it will be found that the work of electric auxiliary heating is close to 1000 watt.

Comprehensive analysis: By comparing the power consumption of the above two air conditioners in heating state and cooling state, we can actually draw a conclusion that the power consumption of the same number of air conditioners in heating state will be close to 1 2, and some even more, if all the air conditioners are turned on for auxiliary heating. If the auxiliary heating is not turned on, the difference in their power consumption is generally not particularly large, just a little more.

(2): Air conditioning heating, how much electricity is consumed per day 12 hours? Regarding the power consumption of air conditioners in heating state 12 hours, different air conditioners vary greatly. So let's take the common 1.5 air conditioner as an example to briefly introduce the power consumption of this air conditioner in the heating state. To this end, I would like to introduce the following four points to you.

①: The air conditioner has high power when heating. The so-called fully open power of air conditioner during heating refers to the sum of the heating power of air conditioner itself and the power of electric auxiliary heating when we use air conditioner for heating. For example, the heating power of this air conditioner is 980 watts, plus 800 watts of electric auxiliary heating, which is equal to 1780 watts.

②: The status quo of air conditioning heating state. In fact, the current basically determines the power of our air conditioner. For example, the current of this air conditioner in the heating state, the ordinary heating input is 4.6 A, and the electric auxiliary heating is 3.7 A. Therefore, the total current in the heated state is 8.3 amps.

③: Power consumption in heating state of air conditioner. In fact, I have already introduced it to you. The input power of this air conditioner when it is fully opened in heating state is 1760 watts, which is 1.76 kilowatts. So the hourly power consumption of this air conditioner is actually 1.76. Then if you run 12 hours in this state, the required power consumption is 1.76× 12, and the final result is 2 1. 12.

④ We should also know that our air conditioner will set the corresponding temperature when heating. When the heat emitted by the air conditioner meets the indoor temperature demand, the outdoor unit of the air conditioner will generally stop running. According to the conventional empirical data, the general running time of ordinary air conditioners is 60% of the whole process, which means that its actual power consumption may be 60% of the total power consumption. Then the result we get is about 2 1.2 degrees multiplied by 0.6, and our final result is about 13 degrees.

Comprehensive analysis: Through the above brief introduction of the power consumption of air conditioner in heating state, we will find that the power consumption of an air conditioner in heating operation is: 12 hours, which is about 13. But here we also need to consider the sealing effect of our indoor doors and windows and the temperature we set. Because these will lead to changes in the running time of our air conditioner. Therefore, the power consumption of indoor air conditioners should decrease on the basis of the maximum power consumption. That is to say, the maximum power consumption is 2 1.2, and then it may be reduced according to different situations.

(c): How can we save electricity when the air conditioner is heating? In order to save electricity in the heating state of our air conditioner, in fact, the most fundamental thing is to ensure that the heat generated by our air conditioner is effectively used. Then the hot air blown out by the air conditioner outlet is to meet our indoor heating needs as much as possible. The more heat is needed for indoor heating, the greater the power consumption. To this end, it can be solved from the following three aspects.

①: Do a good job in thermal insulation of enclosure structures such as indoor doors and windows and external walls. For example, our indoor and outdoor walls can be used for external insulation and indoor insulation. For our indoor windows, we can choose double-glazed windows or multi-glazed windows. This will reduce the indoor and outdoor heat transfer, so as to maximize the use of the heat generated by our air conditioner.

②: Set the air conditioning temperature reasonably. For air conditioning heating in winter, the higher the air conditioning temperature, the more power consumption. So for heating, my personal opinion is that the temperature of our air conditioner should be set at 27℃ or 28℃ as far as possible. Never set the air conditioning temperature to 30. Generally at 30℃, air conditioning is quite power-consuming.

③: Try to avoid opening doors and windows during air conditioning and heating. As we all know, in the process of heating, if we open doors and windows, it will lead to a rapid decrease in indoor heat. In the simplest case, for example, we may be at 28℃. If we open the door and open the window, it is estimated that it will drop to 24℃ or 25℃ in half an hour. So the heat dissipates very quickly. Then, it will inevitably lead to a sharp increase in our power consumption.
