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.”
Lights Out for Expanded Lighting Energy Efficiency?
The administration is seeking to undo an Obama-era regulation that applies to specialty lightbulbs, leaving it out of the upcoming 2020 federal efficiency standards. These types of bulbs include the decorative globe-like bulbs in bathroom fixtures, reflectors in recessed lighting, and more.
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).
Decreasing Energy Costs as a Produce Facility — a PMA Webinar
The Produce Marketing Association (PMA) hosted an educational webinar about ways in which produce businesses can decrease energy costs, and pursue sustainability goals. Three guest speakers shared their expertise and described the tools and measures they implemented to achieve their desired results.
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?
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.
Energy Audits Reveal Areas Where Cold Storage Facilities Can Save Money
In many facilities, large refrigeration systems are running at 100% capacity and 24/7. This is an area for massive savings because there are controls products out there that automate run times and provide measures that more efficiently meet temperature requirements.
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.
