Abstract
An apparatus includes a flash tank, a load, a first compressor, a heat exchanger, and a second compressor. The flash tank stores a refrigerant and releases the refrigerant as a flash gas. The load uses the refrigerant to remove heat from a space proximate the load. The first compressor compresses the refrigerant from the load and directs the refrigerant to the flash tank. The heat exchanger transfers heat from the refrigerant from a high side heat exchanger to the refrigerant released from the flash tank as the flash gas. The second compressor compresses the refrigerant released from the flash tank as the flash gas.
Claims14
An apparatus comprising:
- a flash tank that stores a refrigerant and to release the refrigerant as a flash gas;
- a freezer that receives the refrigerant from the flash tank such that the refrigerant from the flash tank removes heat from a space proximate the freezer when the refrigerant from the flash tank is in the freezer;
- a first compressor that compresses the refrigerant from the freezer and directs the refrigerant to the flash tank before the refrigerant reaches a second compressor;
- a desuperheater that removes heat from the refrigerant compressed by the first compressor before the refrigerant from the first compressor reaches the flash tank;
- a heat exchanger that transfers heat from the refrigerant from a high side heat exchanger to the refrigerant released from the flash tank as the flash gas;
- and
- the second compressor compresses the refrigerant released from the flash tank as the flash gas.
A method comprising:
- storing a refrigerant in a flash tank;
- releasing the refrigerant from the flash tank as a flash gas;
- receiving, at a freezer, the refrigerant from the flash tank such that the refrigerant from the flash tank removes heat from a space proximate the freezer when the refrigerant from the flash tank is in the load;
- compressing, using a first compressor, the refrigerant from the freezer;
- directing the refrigerant from the first compressor to the flash tank before the refrigerant reaches a second compressor;
- removing, using a desuperheater, heat from the refrigerant compressed by the first compressor before the refrigerant from the first compressor reaches the flash tank;
- transferring, using a heat exchanger, heat from the refrigerant from a high side heat exchanger to the refrigerant released from the flash tank as the flash gas;
- and
- compressing, using the compressor, the refrigerant released from the flash tank as the flash gas.
A system comprising:
- a high side heat exchanger that removes heat from a refrigerant;

- a first compressor that compresses the refrigerant from the freezer and to direct the refrigerant to the flash tank before the refrigerant reaches a second compressor;
- a desuperheater that removes heat from the refrigerant compressed by the first compressor before the refrigerant from the first compressor reaches the flash tank;
- a heat exchanger that transfers heat from the refrigerant from the high side heat exchanger to the refrigerant released from the flash tank as the flash gas;
- and
- the second compressor compresses the refrigerant released from the flash tank as the flash gas.
