The chiller and screw compressor can be used for air-conditioning applications
At Mostra Convegno Expocomfort this month, German compressor and systems manufacturer GEA introduced its new ammonia chiller and screw compressor designed for air-conditioning applications.
“We managed after seven years to produce a semi-hermetic [compact] screw compressor [including an oil separator] for ammonia”, Dirk Oschetzke, product manager screw compressors, GEA, told ammonia21.com, “Everyone thinks from the same look and feel it’s like a [HFC] chiller but It’s different”.
The compressor has copper winding helping to increase the efficiency of the overall system and a suction cooled motor.
The company also introduced a chiller using the semi-hermetic [compact] screw compressor developed by GEA. They believe that with the price of HFCs increasing due to the decreased HFC quota under the new European F-Gas Regulation the product will allow end users the ability to install a future proof solution.
“Everyone is unsure we have new refrigerants, the price [of refrigerant] is going up”, Oschetzke, explained “For this kind of chiller of 1.2MW we have [..] 60 kg of charge ammonia. Others {HFC chillers} have 400 kg of [HFCs] that [can cost] 10,000 euros”.
GEA is not selling the chiller commercially yet but is field testing the product and will start selling it to the market in the near future.
