This product line now includes three new refrigeration leak sealants: AC Leak Freeze nano UV, AC Leak Freeze nano Mini-Split UV, and AC Leak Freeze nano Mini-Split. Using a patent-pending, quick-installing applicator, all three contain the same AC Leak Freeze formula and its nano particle sealing technology for nano-sized leaks, such as those caused by formicary corrosion.
Ventilation systems designed for office buildings may recirculate most of the air and only supply a small percentage of fresh air, but architectural and building codes require that laboratory rooms and vivaria use only fresh outside air for ventilation. This design difference explains why laboratories require so much more energy to operate.
Packaged in a smaller box, the new design connects devices using less DIN rail space. It allows four interoperability functions that can be installed in one device.
Johnson Controls Inc. conducts an annual Energy Efficiency Indicator survey to track current and planned investments, key drivers, and organizational barriers to improving energy efficiency in facilities.* This year marks the 12th edition of the survey, with over 1,900 respondents represented from 20 countries, including 100 leaders from the U.S.
The light load-bearing capacity of a 19th-century timber roof dictated an innovative HVAC retrofit for a historic downtown building renovation that's now home to the Detroit Institute of Music Education, a state-of-the-art music academy.
So with such an obvious demand for workers, why are kids choosing to enter other industries? Well, findings from the Electric & Gas Industries Association (EGIA) Foundation’s 2018 Industry Study "Bridging the HVAC Employment Gap" point to lack of awareness and poor reputation.
The IoT and communicating equipment is pushing the next level of diagnostics for HVACR technicians. Onboard and advanced diagnostics are becoming more commonplace as technicians continue to redefine their daily diagnostic and troubleshooting challenges.
Much as a doctor performs tests to gather clues about a patient’s ailment, service technicians use tools and procedures to accurately pinpoint why an HVACR system will not function properly. The principles guiding these troubleshooting steps are universal, even if their implementation is not.
Guest instructors Anthony Reikow, trainer for Bensalem, Pennsylvania-based B. J. Terroni Co., and Eric Grant, regional sales manager for Fernox, made a compelling case for “keeping it clean” when it comes to hydronic system performance and efficiency.
