SECOP CEO Søholm: HFC phase-down triggering hydrocarbons growth

With global HFC phase-down discussions and the drive for energy efficiency improvements picking up speed, the market for hydrocarbon technology is ripe for growth – particularly in the United States, SECOP CEO Mogens Søholm told at Chillventa yesterday (12 October).

“The best example of these recent big changes is the United States. A couple of years ago, you’d have never believed the US would change this quickly. But today they are very focused both on improving energy efficiency and phasing out HFCs,” said Søholm.

In 2011, the US Environmental Protection Agency approved R290 for commercial food refrigeration, and R600a (isobutane) and R441A (a hydrocarbon blend) for domestic refrigeration. Last year, the agency expanded the regulations, allowing R290 in domestic refrigeration and R600a and R441A in commercial refrigeration. But the charge limits for commercial and domestic applications, in line with UL standards, were set at 150g and 56g, respectively. 

“I strongly believe that with more insight into and knowledge of the technology, regulators will figure out that today’s charge limit of 150g should probably increase,” Søholm said.

He believes the advantages of moving to hydrocarbons are so significant in terms of energy efficiency and environmental impact that the only conceivable obstacle to their wider uptake is flammability. “But […] today’s technology knowhow limits those risks,” he said, pointing out that hydrocarbons have already been used safely in household domestic appliances in Europe and Asia for many years.

There are three key topics for us at Chillventa: natural refrigerants, energy efficiency, and the variable speed aspect – going electronic with these products.

At the heart of SECOP’s product offering for hydrocarbons at Chillventa is the new SLVE compressor, which is more powerful than previous models thanks to its use of energy-optimised components.

“There are three key topics for us at Chillventa: natural refrigerants, energy efficiency, and the variable speed aspect – going electronic with these products,” said Søholm.

SECOP is also showcasing new variable speed drive ‘DLV’ and ‘NLV’ series compressors for use in commercial cooling systems.

“We believe the whole market is changing focus, especially in light commercial. Where we’re putting our development money these days for light commercial is a full range of hydrocarbon compressors – mainly R290,” said Søholm.

“If you convert a traditional R134a system to hydrocarbons, you gain a lot of efficiency by changing the refrigerant alone. If you add variable speed technology on top of that, then you see improvements – in terms of energy efficiency and noise, for example – that are tremendously large,” the SECOP boss said.

The variable speed drive enables needs-based adjustment of cooling capacity and ensures high efficiency even in partial load operations. Compared to fixed speed refrigeration compressors, variable speed drives can achieve energy savings of up to 40%.

Chillventa 2016 is taking place in the German city of Nuremburg from 11-13 October.
