LOW GWP REFRIGERANTS
Legislative changes and import caps mean the industry is moving towards low global warming potential (GWP) refrigerants. Heat exchanger technology has to deal with the different charac- teristics of these new gases. Alfa Laval has devel- oped very specific heat exchanger product de- signs to address the challenges of these current and new low GWP refrigerants. For example, the Alfa Laval DynaStatic distributor is a key feature in the inlet to improve the evaporation of R32 and other new refrigerants.
CERTIFICATIONS MATTER
Designing for energy efficiency is more impor- tant than most people think, and certifications are one way to guarantee performance. A cor- rectly designed heat exchanger in a cooling tow- er allows you to save a significant amount of en- ergy. In an incorrectly sized differential, every 0.3 degree difference is a sacrifice of a cost of 1.25KW per second passing through the heat exchanger.
Alfa Laval plate heat exchangers are certified to the world’s most recognised standard, which is the AHRI (Air-Conditioning, Heating, and Re- frigeration Institute) certification.
DATA CENTRES SET NEW STANDARDS
Data centres have long set the standards in terms of energy efficiency ratings for commer- cial buildings in Australia, but even there, great- er PUE (Power Usage Effectiveness) can be achieved by optimising cooling systems and de- signs. The use of AHRI certified heat exchangers negates the need for external testing, which saves time and gives you guaranteed perfor- mance. Immersion technology is another trend to watch, as cooling requirements continue to increase in this growth industry.
TAKE ENERGY SAVINGS FURTHER WITH WASTE HEAT RECOVERY
In any operation, there is almost always room to continue reducing power consumption and re- lated costs. The secret is in reclaiming the energy
lost as exhaust gas heat and using this in areas such as hot water generation in areas like hospi- tals, laundries or other process lines. As the pio- neer in waste heat recovery, Alfa Laval has the technology and expertise to help you further in- crease your energy efficiency with the Micro ex- haust gas economiser.
