A refrigerator takes heat out of a small compartment by expanding a gas and utilising the laws of thermodynamics; a heat pump pumps warm air, heated by the sun, from a roof cavity into rooms in a houseto warm them and pumping the cold air into the roof to be heated.

How do you increase the COP of a Carnot refrigerator or heat pump?
Decrease temperature difference between cold coolant and hot coolant
Do the refrigerator get the heat out or cool in?
A refrigerator is a form of heat pump. It pumps heat out of something.
What is the difference between heat engine and heat pump?
Heat Engine is the system that converts the Heat energy into mechanical work while Heat pump converts the work into heat
Is a refrigerator is an example of heat pump?
yes it pumps freon
What type of device is a refrigerator?
a heat pump that uses work to move heat
Is a refrigerator an insulator?
No, a refrigerator is a type of heat pump, it takes heat out of the inside and rejects it to a heat exchanger on the back. I don't see how it could be called an insulator
What is the difference between an air conditioner and a heat pump?
An air conditioner if functioning as air warmer or air chiller can be called as a type of heat pump. If an air conditioner is working as an air de-humidifier then it no more a heat pump.
A refrigerator and air conditioner both remove heat from a cold reservoir and into a hot reservoir Why then does an air conditioner cool a room while a refrigerator warms a room?
Both an A/C unit and a fridge pump heat from one area into another. In the A/C unit the heat is pumped out of the room and into a discharge area, normally the outside atmosphere, thus the room is cooled, wheras for a fridge the heat is pumped from inside the fridge out into the room, thus the inside of the fridge is cooled and the room is warmed. The only difference between the working of the two is that the "room" is a different side of the heat pump.
Does a refrigerator change heat into cold remove thermal energy from inside the refrigerator or cause thermal energy to disappear?
Thermal energy never disappears, but it can be moved from one place to another, which is what a refrigerator does. If you examine your refrigerator you will be able to observe that there are heat exchange tubes (usually on the back) which get hot as they pump heat from the interior to the exterior of the refrigerator.
What is the difference between heat and supl heat on a carrier furnace?
Supplemental heat is electric and operates when the heat pump is in defrost mode or when it is too cold outside for the HP to be effective by itself.
Why is refrigerator a heat pump?
It works by pumping the heat that is inside the fridge to the outside, leaving the inside cold. If you put your had behind a fridge you can feel the heat emerging.
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!
