Does the kitchen air conditioner use a lot of electricity

This idea is incorrect, power consumption = power time, high power does not equal high power consumption, if all rooms are installed with ordinary air conditioners, the power of these ordinary air conditioners is much greater than that of household central air conditioners, please refer to the comparison table. The characteristic of household central air conditioning is that the cooling capacity can be transmitted, which room needs it, it will be given to which room, so the total cooling capacity can generally be selected to 20 or less (the average family will not need air conditioning at the same time). And ordinary air conditioners must be selected according to the area of each room, for example:

For a 10m2 room, only 1000W cooling capacity is enough, but there is no 1000W cooling air conditioner on the market, so you have to choose a 2500W (1P) cooling capacity air conditioner, which not only wastes resources, but also comes up with power. If there is usually only one room that needs air conditioning, then with 2500W cooling capacity of ordinary air conditioner, assuming that the compressor works for 4 hours, then with 10000W cooling capacity of household central air conditioning, the compressor can only work for 1 hour to meet the cooling requirements, air conditioning is large, the start-up time is short, the air conditioner is small, the start-up time is long, the power consumption is determined by the heat load, the heat load is the same, the power consumption should be about the same.
