Open System | Closed System |
---|---|
Air is directly led to the space to be cooled. | Dense air passed through pipes all the time. |
Since air is supplied to the refrigerator at atmospheric pressure, the volume of air handled by the compressor is large. | Suction pressure is higher than atmospheric pressure so a smaller volume of air is to be handled by the compressor. |
Moisture leads to the formation of frost at the end of expansion thus drier is used. | Pressure ratio can be reduced which results in higher COP. |
