Difference between Heat pump and Refrigerator

Difference between Heat pump and Refrigerator:

Heat Pump and Refrigerator: In this article we will learn about the difference between Heat pump and Refrigerator. The detailed explanation about difference between Heat Pump and Refrigerator is as follows.

Heat pump:

• The heat pump is the device that used to absorb the heat from low temperature and supply to high temperature.
• The heat pump works on supplying the temperature from low to high, which is from ambient to high, this increases the heat transfer rate.
• The heat pump has always a higher C.O.P than the refrigerator. this depends on the heat transfer rate.
• Heat rejected is taken place by heat absorbed and work done by the pump.
• C.O.P of the heat pump is the ratio of Heat rejected to Work done.

Refrigerator:

• The refrigerator is a device that used to absorb the heat from low temperature and transfers to high temperature.
• The refrigerator works on only removing the heat at low temperature.
• The refrigerator has a lower C.O.P than the Heat pump. this is due to it transfers from low temperature to medium temperature.
• In this heat rejected is takes place only by heat absorbed.
• C.O.P of the refrigerator is the ratio of Heat absorbed to the work supplied.
