Basice refrigeration cycle for air cooled chillers :
the refrigerant in the evaporator aborbs heat from warmer return water ,evaporates to a vapor ,and finally exits the evaporator as a superheated vapor. the superheated refrigerant vapor then enters the suction inlet of the compressor. In the compressor ,the refigerant is compressed ,rasing ites pressure and temperature. High pressure and temperature refrgerant gas exits the compressor,passes through the discharge line and enters the condenser. Whel in the air cooled condenser coil, the hot gas condenses to liquid inside the tubes as it gives up heat to the cooler outside air being drawn across the condenser coil ty the condenser fans.
The condensed liquied refrgerant then leaves the condenser and enters the expasion device.as the refrigerant passes through the expasion device, its pressure and the temperature is decreased to the point theat some of the liquid flashes to vapor. The expansion device controls the amount of fflasing in order to maintain a certain superheat to ensure no liquied droplets entor into the compressor suction.after leaving the expansion device, the refrigerant enters the evaportator and the ccle is repeated.ln order to fit almost any comfort or process cooling application–from new construction to retrofit.
