Abstract
The present disclosure relates to a refrigeration system that includes an evaporator disposed along an evaporator line, a compressor system disposed along a compressor line, a condenser disposed along a condenser line and configured to condense the refrigerant compressed by the compressor system to heat a second fluid stream, and an outdoor coil disposed along a coil line and configured to receive the refrigerant from the condenser or from a discharge line, to selectively transfer heat to or from the refrigerant, and to selectively transfer the refrigerant to the evaporator or to a suction line. The refrigeration system includes two valves and three expansion valves disposed along the different refrigerant flow lines, and a controller configured to determine a simultaneous heating/cooling operating mode of the refrigeration system and to control the valves and expansion valves to operate the refrigeration system in the desired mode.
