Reliable and high efficiency R744/R717 cascade heat exchanger

The refrigeration industry has seen a growing interest in using carbon dioxide (CO2) as secondary media combined with ammonia in cascade applications. Carbon dioxide requires lower pumping cost and smaller pipes then glycol and brines.

However the higher pressure levels of CO2 creates a challenge for the CO2/ Ammonia cascade heat exchanger, mainly related to pressure and thermal fatigue.

Alfa Laval has invested significant time and effort in the R&D of semi-welded plate heat exchanger technology for cascade duties. This presentation focuses on the benefits of this groundbreaking new solution with the potential to revolutionise future system design.

Navigating a changing refrigerants market

A massive change is currently underway in the refrigerant market. Driven by environmental concerns, legislation is pushing a gradual phasing out of traditional refrigerants in favour of low GWP refrigerants to address climate change and global warming. The impact of these new rules will dramatically alter the way heating and cooling applications are performed in a wide range of industries over the coming years. Businesses, where these applications are central, are thus facing a major question: Which refrigerant makes the best sense for my HVAC duty?
