The North American Sustainable Refrigeration Council recently presented a natural refrigerant seminar and live CO2 demo at the Danfoss headquarters in Baltimore, Maryland.
This hunger for knowledge about refrigerants is apparent all around the industry. At the recently held AHR Expo, for example, there were several information sessions offered on refrigerants, and all were packed with attendees who wanted to know more.
Our Lady of Guadalupe Catholic Church’s community center in the Tempe, Arizona suburb of Guadalupe now has state-of-the-art HVAC thanks to variable refrigerant flow equipment, accessories, and installation labor donations from RectorSeal, Panasonic Air Conditioning Group (a division of Panasonic Corp. of North America), and Woody’s Heating and Air Conditioning.
A critical step in the installation of a built-up (field-piped) refrigeration system is the startup and commissioning of the equipment, which simply means verifying the operation of the system and its components. Although this seems obvious, it is a step that is occasionally skipped or done too quickly to be effective.
Evacuation is often called “vacuum” or “pulling a vacuum,” and it’s one of the most important parts of the HVACR installation and repair process where the refrigerant circuit is involved. Our goal should be to keep the closed refrigeration circuit clean, dry, and tight — just like I was taught since the very first week of HVAC school.
The global demand for cooling is growing exponentially, which could place serious strains on electrical grids around the world. This increasing demand is coming primarily from developing nations in hotter parts of the world, such as India, where the peak electricity load for air conditioning could reach 45 percent in 2050, up from 10 percent today.
Intermatic Inc. announced a new strategic partnership with LAE Electronic, a global manufacturer of compact refrigeration control solutions. The partnership expands Intermatic’s capabilities within the HVACR OEM space and brings new solutions to customers throughout North America under the LAE by Intermatic brand.
Dakota Refrigeration’s large service area can result in lengthy travel time to the job-site. Mike’s team was challenged with a refrigeration equipment install 200 miles from the shop. This means incurring additional costs for weekly drive time, employee lodging, and daily allowances.
