Cooling capacity means the amount of heat energy that can be pumped from inside of the room (usually low temperature) to outside of that room(usually high temperature). This can not happen naturally as heat energy can flow only from high temperature to low temperature.
To make it happen, external work has to be done on a system to transfer heat from low to high temperature. This work done is mechanical form of energy which is equal to the electrical energy consumed. Hence, mechanical power=electrical power(not considering efficiency of the compressor etc.)
This electrical power(such as 1875 W) is consumed to pump 5275 W of heat out of a room.

Net heat dissipated by the system is only the energy consumed in form of electrical energy; but, energy emitted outside the room in an hour = 1875+5275 = 7150 Watt hour by consuming 1875 Watt hour of electrical energy.
