Abstract:
1. A refrigeration system for cooling a space using a refrigerant, the refrigeration system comprising: a refrigeration circuit including a controller programmed to control the operation of the plurality of variable capacity compressors to match the capacity of the plurality of variable capacity compressors to the load when the first compressor and the last compressor are each running below maximum capacity and above minimum capacity by increasing the capacity of the last compressor in the queue and not increasing the capacity of the first compressor in the queue when the capacity of the plurality of variable capacity compressors is lower than the load and by decreasing the capacity of the first compressor in the queue and not decreasing the capacity of the last compressor in the queue when the capacity of the plurality of variable capacity compressors is higher than the load.
