Abstract: A refrigeration system includes first and second compressors, a condenser, first and second evaporators, and a valve. The first compressor is fluidly connected to first suction and discharge lines. The second compressor is fluidly connected to second suction and discharge lines. The second suction line is fluidly connected to the first discharge line. The condenser receives refrigerant from the second compressor. The first evaporator receives refrigerant from the condenser and discharges refrigerant to the first suction line. The second evaporator receives refrigerant from the condenser and discharges refrigerant to the second suction line. The valve is disposed between the first evaporator and the first suction line. The first suction line receives refrigerant when the valve is in a first position. The second suction line receives refrigerant when the valve is in a second position. The first compressor is bypassed when the valve is in the second position.
