COP of any refrigerating system mainly depends on the performance of the compressors used and the heat load at the evaporator. A similar or almost equal COP can be achieved from any system by varying its working parameters like load, kind of refrigerant used and the system working pressure.

Why cant a refrigerator be used as an air conditioner as the working principle of both is same?
A refrigerator is designed to pump heat from the inside of the refrigerator to the outside of the refrigerator. Since the refrigerator is inside a room (usually a kitchen) the heat does not escape from the house that it is in. If you examine your refrigerator you will find that there is a heat exchange unit, usually in the back (although it can be on the sides) which gets hot. So if you leave the door open, any cool air that escapes into the room is more than balanced by the heat coming from the heat exchange unit in the back. An air conditioner, in comparison, is designed to pump heat from the inside of a house to the outside of a house. If, however, you were able to mount your refrigerator inside a window frame (which would be extremely difficult) and make a reasonably air tight seal, you could then leave the refrigerator door open, and use the refrigerator as an air conditioner. It would be a lot easier to just get an actual air conditioner, however.
What consumes more power a light bulb or a refrigerator when they are on?
Refrigerator- it takes more power to kick on and it pulls more electricity than a light bulb
Does a black refrigerator take more power to cool because it absorbs heat?
Short answer, no. In an average kitchen, a black refrigerator would have to be in direct sunlight most of the day. Ambient room temperature would not heat it more than a white refrigerator. If the black refrigerator has excellent insulation, it may be more energy efficient than a different color, even when outside in direct sunlight.
What temperature do you keep your refrigerator at to preserve foods?
Generally you want your refrigerator to be no more than 42 degrees and no less than 38 degrees (or things will start to freeze).
How long can steamed rice stay in refrigerator?
no more than four days
Does a 100w light bulb use more electricity than a refrigerator?
A 100 watt light bulb draws a little less than one amp. A refrigerator draws much more when compressor is running. The duty cycle of the light and refrigerator will ultimately determine which uses more power on a Kilowatt Hour basis.
Do wild turkeys weigh more than domestic turkeys?
Wild turkeys do not weigh more than domestic turkeys on average. Wild turkeys move around a lot looking for food, domestic turkeys don't have to, causing them to get heavier.
Are BMW's more expensive to service and repair than domestic vehicles?
It depends what you mean by a domestic vehicle. BMWs are domestic vehicle too. In Germany.
Will running an frozen air conditioner cause damage?
More than likely yes.
Why is a deep chest freezer more efficient than a refrigerator?
It is usually because a freezer is closed for a lot more time than a fridge.
Does refrigerator affect temperature of room?
A refrigerator is a "heat pump." That is, it pumps heat out of a cold area (inside) to a warm area (the room). Thus, when working at its best, a refrigerator is a heater. However, the laws of thermodynamics assures us that it will always use more energy than it puts to work, so that extra energy will also heat the room. That is why your air conditioner (another kind of heat pump) is outdoors: if it were indoors, it would heat the room it was trying to cool!
Does a refrigerator with two door burn more energy than one with one door?
no
