Refrigerating capacity and refrigeration power? (urgent)

1. Different units:

Cooling capacity: When the air conditioner is running for cooling, the total amount of heat taken away from a closed space, room or area per unit time, the unit is w.

Cooling power: When the air conditioner is running for refrigeration, the total power consumed within the rated time is its refrigeration power, the unit is W.

Second, the meaning is different:

The cooling capacity of the air conditioner is actually the heat "moved" out of the used room, and the cooling effect is achieved by transferring heat.

Air conditioning power: The more power the air conditioner consumes to operate, the more power it saves, and the faster the circulating air volume cools down. Air conditioning is as stable as cooling. 1-2 Depending on the environment, the temperature changes from running to the set temperature and stops. Refrigeration capacity of civil air conditioners:

The principle for selecting cooling capacity is: the cooling capacity of the air conditioner should be slightly greater than the cooling load of the room. The heat load of the room should consider the orientation of the room, the insulation of the walls and roof, and the indoor Factors such as the number of people in the heat source.
