Buying new, higher-efficiency refrigeration equipment can be cost prohibitive, which is why making targeted retrofits or upgrades to existing systems may make the most sense for many food retailers.

A grocery store owner in Georgia does a daily inspection of all refrigerated and frozen case temperatures using a laptop computer with specialized commercial software.

When servicing a refrigeration system, it is important to accurately determine the true cause of the failure. Misdiagnosing the problem can often create additional system issues for you and the customer.

The TXV also simultaneously controls a set amount of evaporator superheat while, under these same conditions, assuming the range and capacity of the valve is not exceeded.

These technologies continue to evolve and change as systems become more efficient and as new methods are discovered to improve the refrigeration cycle. As such, the importance of continuing education cannot be emphasized enough.

The higher the inlet water temperature, the more sensible heat must be removed from the water and the longer the freeze cycle. The latent heat removed causes the water to change state, thus producing ice.

At the symposium, industry experts from Danfoss, refrigeration OEMs, end users, regulators, advocacy groups, and refrigerant producers came together to discuss some of the challenges facing the industry, as well as new technologies and megatrends that will impact every aspect of the commercial refrigeration market.

To obtain the heat content (enthalpy), it would be necessary to know both the pressure and temperature at this point and then use a thermal dynamic superheat table for this specific refrigerant.

Many end users, as well as refrigeration engineers and contractors, attended Food Marketing Institute’s (FMI’s) 2018 Energy & Store Development Conference in Atlanta, looking for advice on how to respond to these trends.
