GREEN GUIDE PART TWO
This decreases stress on the motor, helping to extend the machine’s lifespan and ensure the cooling aspects of your business stay up and running. The use of an inverter
eliminates the need for the start relays, start capacitors and run capacitors required in on-off compressors.
Fewer parts that can fail from everyday wear and tear also helps to provide a better long- term return on your equipment investment. Additionally, having fewer parts and decreased equipment stress levels leads to significant operating noise reduction.
Hydrocarbon (Natural) vs.
Hydrofluorocarbon Refrigerant The global warming potential of
refrigerant gas drops from 3922 all the way down to 3 when using a natural option, like R-290, rather than a hydrofluorocarbon (HFC) refrigerant, like R-404A. Additionally, the total refrigerant charge drops from 350g to less than 150g, significantly reducing your direct carbon footprint. Switching to a natural
refrigerant can reduce energy consumption by up to 20%. Using that natural refrigerant in a VCC, rather than in an on-off compressor, can reduce energy consumption by another 20%, providing an ROI that can pay for itself in as little as six months. It’s a win-win
combination for sustainability and profitability.
Ambient vs. Prod Ambient vs. Product Temper- ature
Compared to on-off compressors, VCCs recover from door openings much faster. Operating at variable speeds enables these compressors to more easily and quickly regulate the delta between product and ambient temperatures. The higher the temperature delta, such as in freezers and other equipment operating at lower temperatures, the greater the ROI a VCC provides.
In fact, VCCs have shown a
20% average pulldown reduction, enabling the compressor to run at lower, energy-saving speeds. This ability to better regulate temperature also makes VCCs a highly effective solution for food preservation and medical applications, where products are very sensitive to temperature oscillations.
Compact vs. Conventional Layout
VCCs are not only energy efficient, they are space efficient, too. A VCC with natural refrigerant generates the same cooling capacity of a conventional on-off compressor using HFC gas, but in a much more compact equipment layout. By freeing up more
merchandising space in
commercial cabinets without changing any external
dimensions, manufacturers can more creatively design equipment and provide more flexible layout options to stores.
The Advantages of VCCs are Obvious
After comparing the benefits of VCCs with natural refrigerant vs. on-off compressors, it’s easy to see why so many businesses are adopting this more efficient and reliable technology. It helps you to significantly reduce the environmental impact of your business while realizing energy savings that positively impact your bottom line.
Major refrigeration brands, like Embraco, a portfolio brand of Nidec Global Appliance, now offer a wide range of VCC and natural refrigerant options.
These trusted suppliers can help you access all the environmental — and, just as importantly, financial — benefits of making the switch to a more cost-effective way to increase equipment lifespan, company sustainability and ROI.
