(54)	EVAPORATIVELY COOLED REFIGERATION SYSTEM AND METHOD

(57) An evaporatively cooled refrigeration system (100) includes a refrigerant, a gas/liquid separator (102), an expansion valve (108) in fluid connection to the gas/liquid separator (102), an evaporator (106) to receive the refrigerant from the expansion valve (108), a compressor (118) configured to compress the refrigerant in fluid connection to the evaporator (106), and a gas cooler (120) in fluid connection to the compressor (118). The gas cooler (120) includes an indirect heat exchanger (140) to convey the refrigerant and facilitate heat from the refrigerant and a spray system (130) to spray an evaporative coolant on the indirect heat exchanger (140). Evaporative cooling provided by the evaporative coolant on the coil is configured to cool the refrigerant below a dry bulb ambient air temperature.
