Lab Manual 1 Vapour Compression - SEE2101 Thermosciences.
2016年10月17日 · The vapour first cools and then condenses into liquid by releasing the latent heat at constant pressure and temperature (Points T4 to T5). Heat from the refrigerant is transferred to the stream of water in the condenser. The liquid refrigerant then passes through the throttling/expansion valve where it expands.
