New VRF A/C Training Center Epitomizes HVAC/R Industry’s Trend Toward Installation Aesthetics
April 8, 2013
Fort Worth, Texas–The hundreds of HVAC/R contractors expected to attend air conditioning system classes at distributor, Quietside’s newly-expanded training center will learn as much about installation aesthetics as they will about Samsung’s Variable Refrigerant Flow (VRF) systems

“There’s an HVAC/R trend that’s pressuring contractors to make an air-conditioning installations look as good as they function,” said Matt Wall, system air conditioning engineering and VRF technical trainer, Quietside-Texas, Fort Worth, Texas, which is the master distributor of Samsung air conditioning products in North America.  ”Architects and engineers are realizing the visual impact a competed project makes on building owners and prospective clients can greatly affect their future business.  Air conditioning systems can’t just work well anymore, they have to look great tooThis aesthetics trend was the Quietside technical support staff’s impetus for showcasing not only Samsung’s DVM Plus III Series VRF equipment, but also accessories that create a professional appearance.  Therefore, Wall specified Aspen Pumps for condensate management, the PD-Series of lineset ducting and Big Foot Systems equipment mounts for supporting the VRF–all which is available from the new Engineered Products division of RectorSeal Corp., Houston.

Contractors attending any of Quietside’s 16 two-day VRF training seminars every year now get hands-on demonstrations of the training center’s working VRF equipment and the installation accessories. The two-day seminars cover everything from VRF basics and installation to wiring, commissioning and now accessories.

The Carrollton, Texas office of HVAC/R contractor, Bell Mechanical, Baton Rouge, La., installed one 10-ton heat recovery unit supplying nine evaporator coils; and two 8-ton heat recovery units and one 8-ton heat pump, which supplies one evaporator coil each. The outdoor, ground-level equipment supplies the 1,200-square-foot training center, warehouse, assembly area and offices that were included in the expansion of the five-year-old, 52,000-square-foot building, one of four Quietside distribution facilities in the U.S. “VRF systems are really driving the trend of using all these accessories to make a project look professional,” said Mike Bell, president, Bell Mechanical.

Quick and easily-assembled mounting supports are the aesthetic foundation for an aesthetic installation, according to Wall. The three DVM units are mounted on Big Foot Systems’ prefabricated 1.6-square-inch corrosion-resistant, hot-dipped galvanized tube modules supported by 1-square-foot UV-protected, glass-filled nylon footings with anti-vibration mat bases.  The VRF units are 18-inches off the ground for easier serviceability and protection against landscaping tools.  The modular supports were assembled within minutes and reduce mounting costs by more than half versus I-beam rails, poured cement pads or other conventional methods. Leveling the equipment requires only wrenching one or more of the four adjustable support legs.

Lineset protection duct makes the most noticeable difference in installation aesthetics, Wall said. Each unit’s linesets are enclosed in their own gray 4.7-inch-diameter round PVC plastic ducts from RectorSeal’s PD-Series. The lineset ducts themselves are also supported every 10 feet by a series of  piping support footings.  Bell Mechanical used three elbows and two flanges on each of the three runs that total more than 60 linear feet.  ”Protective ducts also help contractors maintain level piping throughout the run and avoid sagging or low spots that can lead to oil migration issues,” said Wall.

“Lineset protection ducts are invaluable for retrofit work, because generally there’s no opportunity to hide linesets under roofs and inside walls as exists with new construction projects,” said Bell, who uses lineset protection ducts and condensate pumps regularly on ductless air conditioning.

GasGuard™ Locking HVAC/R Refrigerant Valve Caps Help Prevent Leaks, Theft & “Huffing”
April 3, 2013

The GasGuard new product press release pasted below will save lives. RectorSeal wants contractors to become more aware that teens are dying from “huffing,” a new trend of inhaling poisonous refrigerant out of HVAC/R outdoor units. One solution is to prevent access to refrigerants by installing locking caps, such as GasGuard, which is now an International Mechanical Code mandate for new installations. By 2015, the IMC will require all contractors to install a locking cap of some kind any time they open a system–old or new.

But don’t take our word for it about this shocking trend. Here are some excerpts from the United Parents to Restrict Open Access to Refrigerants (UPROAR) website.

The Center for Disease Control and Prevention (CDC) reports that nationwide, 13.3% (up from 12.4% in 2005) of all surveyed students had used inhalants to get high one or more times during their life (lifetime inhalant use).

For more refrigerant specific stats: An analysis of 144 Texas death certificates by the Texas Commission on Alcohol and Drug Abuse involving misuse of inhalants found that the most frequently mentioned inhalant (35%) was Freon (51 deaths). Of the Freon deaths, 42 percent were students or youth with a mean age of 16.4 years.
