Oil-Filled Temperature Sensors for HVACR 101
Oil-filled temperature sensors are one of three, general sensor options along with electronic or gas-filled. Oil-filled may be worth considering if, for example, you wanted to track something like the internal temperature of stored product. This blog post introduces oil-filled temperature sensors.
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.”
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.
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?
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.
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.
4 “Check Engine” Warnings for Your HVACR System
Refrigeration systems have a great deal of both mechanical and electrical components that need periodic maintenance to keep it running at its most optimal. The easiest comparison is to imagine your business’ refrigeration system as your car.
3 Solenoid Valve Issues That Can Derail Your HVACR’s Energy Efficiency
The solenoid valve is an integral piece of an efficiently operating system. It is electrically switched open by the thermostat during a call for cooling, and its basic function is to prevent or allow refrigerant flow.
