A refrigeration rack is a refrigeration machine fitted with two or more compressors, able to supply several cooling points at the same time. It is an efficient way to match real energy demand, with the following advantages:
• The installation keeps running if one compressor fails.
• A high COP.
• The load is handled by staging the compressors in sequence.
• Fast pull-down by bringing all available compressors on line.
• Significant energy savings
