摘要：A refrigeration system includes a first refrigerant circuit having a first compressor, and a cond refrigerant circuit having a cond compressor, the cond refrigerant circuit parate from the first refrigeration circuit. A variable frequency drive
(VFD) is in signal communication with the first compressor and the cond compressor and is configured to enable a variable speed operation of the first and cond compressors. A controller is in signal communication with the VFD. The controller is programmed to lectively switch the first and cond compressors between a variable speed operation using the VFD and a fixed speed operation such that in a first mode the first compressor is operated in the fixed speed operation and the cond compressor is operated in the variable speed operation, and in a cond mode the cond compressor is operated in the fixed speed operation and the first compressor is operated in the variable speed operation.生日祝福语搞笑
