Walk-in Cooler/Freezer Electric Defrost 101: Efficiency [Part 3]
Now that we know what electric defrost is, how it works and how much it costs—it’s time to talk about how to use it more efficiently by implementing several control strategies.
Walk-in Cooler/Freezer Electric Defrost 101: Cost [Part 2]
Last week, we wrote about why you need electric defrost for your commercial freezer and how it works. This week, we break down the costs associated with defrost, and the potential costs of ice build up on evaporator coils.
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.
The Future of HVACR Energy Efficiency: Monitoring-Based Commissioning
Monitoring-Based Commissioning is a combination of controls, sensors, software and sometimes ‘human review,’ that constantly monitors equipment by way of algorithms and real-time data to detect faults and optimize performance.
Refrigeration Smart Controls and Peak Energy Demand Reduction
Effective demand-limiting strategies will often increase overall energy usage, but they have the potential to yield a lower electric bill in facilities where demand charges are high.
NRM is Proud to Play a Role in the Dunkin’ Brands, National Grid, and Eversource Energy Management Program
The energy management program, available to Dunkin’ Brands franchise owners, seeks to identify opportunities to improve the energy management capabilities of DD locations. NRM has retrofitted hundreds of coolers with their smart controls and energy efficiency measures in coordination with the program.
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.”
In the Grocery Game, Refrigeration and HVACR Must Keep Evolving
As laid out in this article in ACHR News, specific systems are being designed for specific desires. “The days of centralized direct-expansion (DX) systems aren’t necessarily over, but those systems have been joined by a host of new technologies…”
Hey, HVACR Contractors, Here Are 5 Ways Smart Controls Can Improve Your Client Relationships
In today’s post, we would like to highlight how such a platform can result in more consistent preventative maintenance appointments, and improve visibility between refrigeration contractors and their clients (from installers to maintenance technicians).
Evaporator Fan Cycling: Is it Really a Risk?
In most walk-in coolers and freezers, the evaporator fans run 24/7/365, at full speed. This makes evaporator fans an obvious place to look for energy savings in commercial refrigeration. But is it safe to turn them off?
