(54) | COOLING SYSTEM |
(57) This disclosure relates generally to a cooling system. An example embodiment includes a system (200) including a flash tank (110), a first load (120A), a second load (115), a first compressor (130), a second compressor (125), a first valve (205), and a second valve (135). The flash tank (110) stores a refrigerant. The first and second loads (120A, 115) use the refrigerant to cool first and second spaces. The first compressor (130) compresses the refrigerant from the first load (120A) during a first mode of operation and a flash gas from the flash tank (110) during a second mode of operation. The second compressor (125) compresses a mixture of the refrigerant from the first and second loads (120A, 115) during the first mode of operation. The first valve (205) directs the flash gas from the flash tank (110) to the first compressor (130) during the second mode of operation. The second valve (135) directs the compressed flash gas from the first compressor (130) to the first load (120A) during the second mode of operation to defrost the first load (120A).
