The difference between the ideal versus the actual vapor-compression refrigeration cycle can be described briefly in these concerns. In the ideal case, the refrigerant is assumed to leave the condenser as a saturated _____ at the compressor exit pressure. However, it is unavailable to have some pressure drop in the condenser as well as the lines connecting the condenser to the compressor and to the throttling valve. It is near to improbable that we can accurately set to a _____ state of the refrigerant before it enters the compressor as per the case of the ideal refrigeration condition.  Also, it is not easy to execute the _____ process with such precision that the refrigerant is a saturated liquid at the end, and it is undesirable to route the refrigerant to the throttling valve before the refrigerant is completely condensed.

Question

The difference between the ideal versus the actual vapor-compression refrigeration cycle can be described briefly in these concerns.

  1. In the ideal case, the refrigerant is assumed to leave the condenser as a saturated _____ at the compressor exit pressure. However, it is unavailable to have some pressure drop in the condenser as well as the lines connecting the condenser to the compressor and to the throttling valve.
  2. It is near to improbable that we can accurately set to a _____ state of the refrigerant before it enters the compressor as per the case of the ideal refrigeration condition. 
  3. Also, it is not easy to execute the _____ process with such precision that the refrigerant is a saturated liquid at the end, and it is undesirable to route the refrigerant to the throttling valve before the refrigerant is completely condensed.
