Wherein, acquire computer lab wireless indoor equipment heat load through "energy-conserving effect evaluation technology research and development requirement book" or "virtual ammeter technique", indoor wireless equipment heat load includes: power of 2GRRU (or RRU for 2G, 4G), power of 4GBBU, power of 5 GBBU. The heat load of the machine room transmission equipment and the heat load of the optical line terminal are obtained by a virtual electric meter technology.

Specifically, for each switch in the machine room, the switching power supply loss power is obtained through the power supply input power and the power supply output power of the switch, and the first switching power supply loss electric quantity = the switching power supply loss power about the time of the day.

The power consumption of the first air conditioner is obtained through the intelligent electric meter and the switch corresponding to the air conditioner, specifically, the power of the intelligent electric meter and the input power of the switch power supply are obtained, the electric quantity of the intelligent electric meter on the same day and the electric quantity of the switch power supply input virtual electric meter are calculated, the electric quantity of the intelligent electric meter is the power of the intelligent electric meter and the time of the same day, the electric quantity of the switch power supply input virtual electric meter is the input power of the switch power supply and the time of the same day, and the power consumption of the first air conditioner = the electric quantity of the intelligent electric meter-the electric quantity of the switch power supply input virtual electric meter.

Next, an air conditioner actual energy efficiency ratio is determined based on the first master power consumption amount, the first switching power supply power loss amount, and the first air conditioner power consumption amount, specifically, the air conditioner actual energy efficiency ratio = (first master power consumption amount + first switching power supply power loss amount)/the first air conditioner power consumption amount.

Specifically, the first refrigeration capacity = air conditioner actual energy efficiency ratio (1 + energy efficiency ratio temperature coefficient) input power; second cooling capacity = air conditioner actual energy efficiency ratio input power.

It should be noted that, in other embodiments, when the first refrigeration capacity and the second refrigeration capacity are obtained, if the first refrigeration capacity is smaller than the corresponding first capacity threshold or the second refrigeration capacity is smaller than the corresponding second capacity threshold, an alarm prompt message for replacing the air conditioner is output, so that the air conditioner is replaced in time when the refrigeration capacity of the air conditioner is poor.
