The lab will be used to test both single-part refrigerants and various refrigerant blends.

R-32 is an attractive alternative to R-410A because it offers an excellent balance of cost, performance, and low environmental impact, said Scot Swan.

Contractors report that while they have been kept busy maintaining refrigeration systems in grocery stores, restaurant work has slowed down.

Let’s look at how the density of refrigerant entering the compressor’s cylinders affects the mass flow rate of refrigerant through the compressor.

If customers are seeking a more environmentally friendly alternative to HCFCs, there are many options available.

The theme for the second year of this event is “Cold Chain 4 Life.”

The SNAP Rule 23 would allow the use of R-32 and R-454B in new units.

In this month’s troubleshooting problem, the equipment is a reach-in food and beverage storage unit.
