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.
Liquid Subcooling: What it is and When to Apply it
In an exhaustive article for ACHR News, Brian Orr, cofounder of a service company, and founder of HVACRSchool.com, describes it in short: “subcooling tells you that you have a full line of liquid refrigerant in the liquid line.”
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…”
HVACR Contractors: the Key to a Healthy Relationship with Your Customers? Communication
In the relationship between HVACR contractors and their customers who rely on the complex, expensive refrigeration equipment to keep their business alive, neither partner has it easier than the other. Especially when that relationship exists in the restaurant and service industry.
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.
Governor Wolf Establishes Statewide Clean Energy and Energy Efficiency Goals in PA
Governor Wolf laid out his goals for the state for 2025 and then for 2050. The main goals are a reduction in carbon emissions by 26% by 2025, and a whopping 80% by 2050.
Engineer’s Corner: An Opinion on Calculated Versus Deemed Savings Approach
In a deemed savings approach, pre-determined kW and kWh savings are attributable to energy efficiency measures in a particular type of application and in a calculated approach, specific variables involved in the application must be determined beforehand to then calculate the savings.
Coolers/Freezers and Energy Efficiency 101: The 6 Types of Cold Rooms and Their Temperature Requirements
Cold storage. Refrigerated warehouse. Frozen storage. Walk-in cooler. Reach-in cooler. Walk-in freezer. Working with commercial refrigeration systems, you may see these descriptors thrown about sometimes to describe the same space.
Compressor Short Cycling: A Hard-to-Find Energy Waster
Short cycling occurs in your compressor when a mechanical failure is causing the run times to terminate prematurely and since set point has not been achieved, it restarts shortly afterward, thus requiring more compressor ‘ON’ time to compensate.
