Difference  Heat Pump  Refrigerator

HEAT PUMP	Refrigerator
1) Heat pump is a device to maintain temperature of the system above the atmospheric temperature.	1)Refrigerator is a device used to maintain the temperature of the system below the atmospheric temperature.
2) Heat pump transfers heat energy from low temp thermal reservoir to High temperature thermal reservoir with the help of external work, with useful space is high temperature reservoir.	2) A refrigerator transfers heat energy from low temperature reservoir to high temperature reservoir with the help of external work, the only difference is that the useful space is Low temperature reservoir.
3) Evaporator is located outside room or external space.	3) Evaporator is located inside room or internal space.
