The present application provides a refrigeration system. The refrigeration system may include an evaporator assembly, a suction header assembly with a suction header heat exchanger therein, and a liquid header in communication with the suction header heat exchanger.

Integrated suction header assembly

An apparatus includes a first compressor, a first load, a second compressor, a second load, and a heat exchanger. The first compressor compresses a first refrigerant. The first load uses the first refrigerant to remove heat from a space proximate the first load. The first load sends the first refrigerant to the first compressor. The second compressor compresses a second refrigerant. The second load uses the second refrigerant to remove heat from a space proximate the second load. The second load sends the second refrigerant to the second compressor. The heat exchanger receives the first refrigerant from the first compressor and receives the second refrigerant from the second compressor. The heat exchanger transfers heat from the first refrigerant to the second refrigerant. The heat exchanger discharges the first refrigerant to the first load and discharges the second refrigerant to the second compressor.

Cooling system with intermediary heat exchange

The present application provides a refrigeration system. The refrigeration system may include a suction header, a compressor, a suction header oil return line in communication with the suction header and the compressor, and an oil line control system. The oil line control system may include a sensor and a valve to open and shut the suction header oil return line in response to the sensor.

Oil line control system

An apparatus includes a first compressor, a first load, a second compressor, a second load, a first heat exchanger, and a second heat exchanger. The first compressor compresses a first refrigerant. The first load uses the first refrigerant to remove heat from a space proximate the first load. The first load sends the first refrigerant to the first compressor. The second compressor compresses a second refrigerant. The second load uses the second refrigerant to remove heat from a space proximate the second load. The second load sends the second refrigerant to the second compressor. The first heat exchanger receives the first refrigerant from the first compressor. The first heat exchanger transfers heat from the first refrigerant to a fluid. The second heat exchanger receives the second refrigerant from the second compressor. The second heat exchanger transfers heat from the fluid to the second refrigerant.

Cooling system with intermediate heat exchange fluid loop

An apparatus includes a compressor, a load, a heat exchanger, and a heater. The compressor compresses a refrigerant. The load uses the refrigerant to remove heat from a space proximate the load. The load sends the refrigerant to the compressor. The heat exchanger receives the refrigerant from the compressor. The heat exchanger transfers heat from a fluid to the refrigerant. The heat exchanger discharges the refrigerant to the compressor. The heater adds heat to the fluid.
