Component manufacturer Güntner expects the industrial and commercial cooling industry to go for ammonia and CO2, based on feedback from customers at Chillventa 2016.
At the 2014 Gustav Lorentzen conference in Hangzhou, China, a comparative study was presented examining the applicability of five single stage vapour compression heat pumps (VCHP) using the refrigerants R134a, R290, R717LP, R717HP and R744. The study considers operational and economic constraints such as refrigeration equipment availability and positive Net Present Value of Investment. It concludes that the LP R717, HP R717 and transcritical R744 heat pumps are advantageous when considering the
ammonia21.com reporters attended a series of presentations on low charge ammonia refrigeration systems during the Nashville IIAR research panels. Presentations from Creative Thermal Solutions, Azane and Mayekawa highlighted new opportunities for expanding ammonia’s application range, thanks to the changing legislative environment. However, a change in perception is necessary for this to become reality, which could be achieved thanks to lower charge systems.
