6 Commercial Walk-In Cooler & Freezer Maintenance Tips
Maintained walk-in coolers and freezers function better. Because of this, they operate more efficiently than a cooler that is not maintained, which in turn means less money spent on bills.
Refrigeration Problem of the Week: Freezer Compressor at Risk
Large commercial and industrial refrigeration systems are, despite their mammoth size, routinely affected by small, unseen issues. Small, of course, referring to the physical component experiencing the issue (fuses, switches, wiring) and not to their potential negative impact.
Coolers/Freezers and Energy Efficiency 101: The Definitive Lighting Guide
The lighting solutions we will evaluate are: fluorescent, metal halide, high-pressure sodium, and LED. LED solutions may seem like costly investments upfront but their long-term cost of ownership and efficiency improvements over the other fixtures may actually surprise some people.
In Connected, Smart Technologies, the HVACR Industry Sees a Real Game-Changer
Anette Meyer Holley, general manager of BSRIA, sees service and maintenance as an industry to benefit greatly. “We estimate the U.S. market to reach some $8B in 2018,” Holley said. “Smart maintenance has become a real business opportunity.”
Contractors and Customers Alike Can’t Live Without Refrigeration Controls and Monitoring
“It’s almost like the check engine light in your car.” This is how Charlie Sternberg, owner of S&S Refrigeration Co. in New Jersey, described the base value of NRM’s monitoring platform to greenHVACR magazine.
Is HVAC/Refrigeration Automation the Next Big Thing for IoT?
Lighting, heating systems, and refrigeration systems can all stand to be improved either through incorporation into a Building Management System or equipped with their own specific controls and automation tools.
Walk-in Cooler/Freezer Electric Defrost 101 [Part 1]
Here’s a basic rundown: there are defrost heater elements located within the coils of your freezer evaporator units. They are controlled by a time clock and turn on during certain times of the day to keep coils free of ice.
Historically Cold Climate can Wreak Havoc on Air-Cooled Condensing Units
The use of low pressure refrigeration controls (LPC) is mostly found in smaller, refrigerated boxes such as beer coolers. LPC systems operating in low ambient temperatures may experience upset as system pressures are not sufficient to close normally adjusted LPC switches.
