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.
2018 E. Coli Outbreak can be Learning Opportunity for Leafy Greens Industry
The worst E. Coli outbreak in over a decade has affected a widespread swathe of the country—reaching as far as Alaska—but seems to have originated from just one location: Yuma County in southwest Arizona.
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.
Coolers/Freezers and Energy Efficiency 101: Lighting Impact on Refrigerated Load Savings
While upgrading lighting fixtures to more efficient LEDs is a practice that in-and-of-itself reduces electrical usage, many are not aware that this measure also bears an indirect effect on refrigerated load savings.
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.
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.
As Companies Continue to Alter Their Processes to Adhere to FSMA, Some Remain Skeptics
“I would assess this more as a band-aid than a cure-all.” That’s the opinion of John Bovay, a faculty member of UConn and a researcher who dissected the FSMA in a white paper for the journal Applied Economic Perspectives and Policy.
A Quick Crash Course in Suction P-Traps for HVACR
A suction p-trap is a discharge line trap that serves an important function both when the compressor is on and in the act of cooling, and when the compressor is off. It’s a critical piece for the equipment’s proper and efficient operation.
6 Ways to Ensure an Evaporator Fan Energy Efficiency Retrofit is Done Right
The upside to a well-implemented controls retrofit can be huge. The most advanced bring a whole suite of features and capabilities, including adaptive defrost control, web connectivity, intelligent alarms, sophisticated diagnostics and data analytics, and powerful controls for your entire refrigeration system.
6 Do-It-Yourself Ways to Reduce Your Commercial HVAC Energy Costs
Behind refrigeration, HVAC (heating, ventilation and air condition) is the most energy-intensive mechanism in commercial and industrial spaces. In the average commercial building, HVAC accounts for 15% of the building’s energy consumption.
