Refrigeration Problem of the Week: Short Cycling in a Quick-Serve Restaurant’s Freezer
Short cycling is a common issue that often goes undetected because the system is running, and safe temperatures in the space are still maintained, but it’s excessively running much more than it needs to.
5 Easy Ways for New England Businesses to Combat Winter Electric Rate Hikes
People say there are only two guarantees in life: death and taxes. But if you live in New England, lately it seems expecting electric rate hikes in the winter is the third thing to add to the list.
2017 Sees the Finalization of New WICF Regulations for Energy Efficiency; Compliance by 2020
These new standards will have an impact on a wide range of refrigeration systems. They will affect everything from low-temperature dedicated condensing systems, to more common systems like medium- and low-temperature walk-ins.
Where’s the Most Expensive Ice in the World? On Your Evaporator Coils
When evaporator coils ice up, efficiency drops dramatically, temperature set points are hard to maintain, it could damage equipment, and it puts perishable products at risk. Run time increases and operating costs can potentially go up by over 100%.
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.
Refrigeration Problem of the Week: Evaporator Fans Shut Off Manually
Evaporator fans being turned off by employees is a common, routine occurrence in convenience store walk-ins. The fans are usually turned off during deliveries, product stocking, and inventory, situations where the noise and cold air make for less-than-ideal working environments.
Tripped Circuit Breaker? Sometimes The Easy Diagnosis Isn’t So Easy
Approaching issues with expensive, complex refrigeration systems with a deferential mindset is very problematic. It often doesn’t get to the root of the issue, and allows for the potential for future system failure.
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.
