NettetRefrigerant R-134a leaves the evaporator as saturated vapor, which is state 2. P 2 = 200 kPa. T 2 = T sat. @ 200 kPa = -10.09 o C. During this process, refrigerant R-134 absorbs 150 kJ heat. Q = 150 kJ. Hence, the entropy change for refrigerant R-134a from process 1-2 is. Temperature T is a constant in this case, and the above equation can be ... Nettet11. apr. 2024 · Inside a system, the refrigerant in the evaporator boils as it absorbs heat. The refrigerant can absorb a lot of heat due to the heat required to change state, also known as latent heat (compared to sensible heat, which is the heat required to raise the temperature of a substance). Until the refrigerant completely boils off, it is at saturation.
