The energy efficiency level of electrical appliances actually depends on the consumption of the same electric energy. The following small series will introduce to you the less energy efficiency of air conditioning, the less power consumption? How much money can be saved in one year compared with grade two or three?
The less energy efficiency of air conditioning, the less power consumption
In fact, the energy efficiency of general air conditioning refers to the ratio of air conditioning rated cooling capacity and rated power consumption. Generally speaking, the first level energy efficiency is no, and the third level energy efficiency is more energy-saving. But how much electricity can we save?
It is generally assumed that when the cooling capacity of a class I energy efficiency air conditioner reaches 3000W, it will consume 0.83 degrees of electricity per hour, while the three-level energy-efficient air-conditioner consumes about 1 degree of electricity under the same cooling capacity. In fact, it seems that there is no difference in terms of saving 0.17 degrees of electricity per hour. According to 8 hours a day, it will save 1.36 kilowatts of electricity every day. In summer, it is about 120 days The remaining 163 kilowatts of electricity are different in different places, so we have to calculate the specific saved price according to the local actual situation.
In fact, the average household electricity consumption is about 0.8 yuan per kilowatt hour, which is equivalent to saving about 130 yuan in that year. However, the price of air conditioning with primary energy consumption must be higher than that of air conditioning with secondary and tertiary energy consumption, but it costs a lot of money. Therefore, generally speaking, we also suggest that we should consider the selection of air conditioning according to their own comprehensive situation.
