These are the condition of the refrigerant at the following points of the refrigeration cycle:
Entering evaporator: liquid-vapor mixture
Leaving evaporator: vapor
Entering compressor: vapor (low-pressure)
Leaving compressor: vapor (high-pressure)
Entering condenser: liquid-vapor mixture (starts as vapor)
Leaving condenser: liquid
A vapor compression refrigeration system is a system consisting of circulating refrigerant through stages of a closed system to create a cold environment that's conducive to preserving and storing products.
There are several parts in a refrigeration system that can change the condition of refrigerant during certain points of the cycle.
Evaporator is a part that turns the liquid form of refrigerant into its gaseous-form (vapor).
Compressor is a part that compresses the refrigerant to a higher-pressure.
Condenser is a part that condense the gaseous-form of refrigerant into a liquid state through cooling process.
