Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFIn the room A.C, the vapour compression cycle is utilised. In this cycle, the refrigerant vapours are compressed in the compressor and then sent to the condenser for phase change. After passing through the condenser, it is expanded in the expansion valve and then passed through the evaporator to produce a cooling effect.
In Evaporator: As the liquid refrigerant flows through the evaporator, it absorbs heat and changes from the liquid state to a saturated vapour.
In Compressor: Due to the work done on it during compression, the gas further superheated. Therefore the temperature of the discharge gas will be much higher than the saturation temperature of vapour corresponding to discharge pressure.
In Condenser: In the condenser, the temperature of the superheated vapour has to be brought down to its saturation temperature before it can be condensed into a liquid.
