Webv. t. e. A transcritical cycle is a closed thermodynamic cycle where the working fluid goes through both subcritical and supercritical states. In particular, for power cycles the working fluid is kept in the liquid region during the compression phase and in vapour and/or supercritical conditions during the expansion phase.

WebThis is shown on T-S diagram of Fig. 36.30. The effect of this superheating of vapour on the performance of the cycle COP can be studied from this diagram. The vapour is drawn in the compressor cylinder at the condition of 1′ and is compressed to 2′, the temperature being T sup. Remaining cycle processes remain unchanged as shown. WebSep 15, 2024 · The Evaporator. The evaporator does the exact opposite of the condenser. Instead of turning the refrigerant from gas to liquid, it turns the refrigerant from liquid to gas (thus the name “evaporator”). Instead of expelling heat, it absorbs heat and turns the air cold around it. This is where the “conditioning” of the air occurs.
