Critical point of refrigerant
WebThe refrigerant discharged from the compressor flows into the gas cooler where heat is re-moved. The refrigerant does not con-dense in this part of the system if it is above the critical point. The refrigerant passes through a high-pressure reducing valve and con-denses in the receiver/flash tank when its pressure drops below the critical point. WebCritical point: The end point of the pressure-temperature curve that designates conditions under which a liquid and its vapor can coexist. At higher temperatures, the gas cannot be liquefied by pressure alone. At …

But, with R-410a since it is a blended refrigerant of R-32 and R-125 there will be a glide during refrigerant state changes. This is because the two refrigerants have different state change points.
WebA saturation dome uses the projection of a P– v –T diagram (pressure, specific volume, and temperature) onto the P– v plane. The points that create the left-hand side of the dome represent the saturated liquid states, while the points on the right-hand side represent the saturated vapor states (commonly referred to as the “dry” region).
