One of the ways to overcome the flammability is the use of a secondary loop system by which the refrigerant is isolated to the outside of the working environment.
Replacements for HFC-134a such as HFC-152a and carbon dioxide will be addressed in the technical sessions and workshop, which will include in-depth discussion of electric and secondary loop air-conditioning systems.
Some of the ways the chain is using sustainable practice includes plastic bins in the produce department, nightshades on chiller cases at night, reusing display packaging up to five times, investment in secondary loop refrigeration systems and LED lights, Munoz said.
The secondary loop is maintained at a lower temperature than the primary loop and is fed with water from the primary loop as necessary to maintain this temperature.
