What is the typical temperature of the refrigerant vapor entering the compressor?

The typical temperature of refrigerant vapor entering the compressor is commonly around 26°F. This temperature is significant in the refrigeration cycle as it represents the state of the refrigerant after it has absorbed heat from the evaporator and has become vaporized.

At approximately 26°F, the refrigerant has enough energy to transition from the liquid phase to the vapor phase, effectively carrying the heat absorbed from the environment. The compressor’s role is to raise the pressure and temperature of this vaporized refrigerant to facilitate effective heat removal in the condenser, which subsequently allows the refrigerant to release the heat it collected in the evaporator.

Understanding this temperature helps operators ensure that the system is functioning efficiently. If the vapor entering the compressor is too cold, it may indicate insufficient heat absorption, whereas if it's excessively warm, it might suggest a problem in the system that requires attention, such as insufficient refrigerant or issues with the evaporator.
