supermarket refrigeration
Industrial refrigeration consumes more energy per cubic foot than any other utility load. Refrigerated facilities are energy intense and have a large peak demand. This demand creates significant impact on the grid. For an owner or operator, these facilities are expensive to operate. Thermal storage creates the opportunity to save energy and reduce or shift peak demand – resulting in energy cost savings. It also increases system resiliency. More
This field study evaluated the performance of variable frequency drives retrofitted to condenser fans in supermarket refrigeration systems. More

Refrigeration is a massive energy consumer in commercial and industrial buildings. According to the International Institute of Refrigeration's Role of Refrigeration in the Global Economy, it consumes around 17 percent of all electricity in the commercial sector alone. Rising demand and a warming climate mean almost certain expansion for refrigeration. This also means tremendous opportunity for energy savings; effort has gone into implementing many measures to reduce energy use in refrigeration across the country. More
Q-Sync motors are a new type of innovative, highly efficient and cost-effective, permanent magnet synchronous (PMSM) motor. Between our own field research and the existing literature, studies find that in reach-in and walk-in cooler and freezers, Q-Sync motors cost-effectively use 50% - 80% less energy than traditional shaded-pole (SP) and permanent split capacitor (PSC) motors, and are even more efficient than the newer electronically commutated (EC) motors.

Refrigeration is a massive energy suck in commercial and industrial buildings. So much so that tremendous effort has been put into measures to reduce energy use in refrigeration systems across the country. Even though the industry has worked tirelessly to install system controls, there is still a long way to go. Our research team has continued to look for more aggressive solutions in the refrigeration world. Here is a summary of a few of our experiences with new approaches to energy efficiency in refrigeration. More
