Is the heat of the refrigerant in the evaporator not becoming a high temperature gas?
And the refrigerant is heated by the throttle valve before it enters the evaporator. The entropy is constant but the temperature is reduced.
In addition, the refrigerant is variable in the evaporator. The temperature of the refrigerant is essentially constant and its pressure is constant
After the endotherm of the evaporator after the pressure and temperature are constant but become superheat working material is essentially absorbed the latent heat
It is recommended that you look at the inverse Carnot cycle temperature entropy chart enthalpy diagram of the control system see figure more clearly
