MILAN, ITALY, March 27, 2012 – For large HVAC systems Emerson Climate Technologies designed the new Copeland Scroll™ ZP725K compressor for the refrigerant R410A. With a capacity of 158kW* the new Copeland Scroll™ ZP725K opens the door to a widespread use of this refrigerant for air-cooled multi-scroll chillers with a capacity up to 1 MW and up to 1.25 MW if water-cooled. This extra large scroll can easily be combined with other scroll compressors that are identical or lower in size or capacity to offer several possible combinations. This flexibility and reduced complexity is ideal for manufacturers who produce systems with different capacities and enables them to keep only a few compressors in stock. All the assembly designs are Copeland qualified and key in increasing the system seasonal efficiency due to the wide range of capacity modulation – up to the possibility of 12 steps with uneven trio assemblies. Publications from the Eurovent directory demonstrate that systems with scroll technologies and R410A have an overall better seasonal performance compared to similar systems using different refrigerants and compression technologies. Moreover, Emerson’s new CoreSense™ Communications provides the enhanced protection and diagnostic required and expected by this demanding range of applications in HVAC systems. Via RS485 Modbus the system controller is able to gather compressor’s status and working conditions and can adapt or avoid altogether system downtime.
