Parking on the ‘GREEN’ Level A Quarterly Showcase of Innovation for the Parking Industry


Technology: Variable Refrigerant Flow (VRF) BY STEVE LITTLE


T


HIS ISSUE’S TECHNOLOGY FEA- ture focuses on the newest rage to take hold of the heating, ventilating and air conditioning (HVAC) market:Variable Refrigerant Flow, or simplyVRF.


The bestway to explain it is this: Until now,when using split


HVAC systems, you placed one condensing unit outdoors and tied it into one indoor furnace/coil combination, as you have in your home.This has been themode of operation since the incep- tion of air conditioning. Now, with vast improvements of electronic controls and


state-of-the-art manufacturing techniques, what has been com- monplace in Europe and Asia for decades – VRF – has surfaced in the United States, and it is taking its rightful position. Now, you can put one condensing unit outside and amultitude of small air-handling units (or fan/coils) inside. Here is the coolest part (no pun intended):You can heat in


one room and cool in another at the same time, simultaneously. It doesn’t get any better than that. And it doesn’t get anymore effi- cient than that, either. Parking garage owners can experience some of the most


difficult temperature control issues on their properties due to large glass exposures and shifting wind patterns. VRF has come to the rescue. Now, an owner can cool the elevators while heating the lob-


bies, offsetting costly energy. Today, if the single packaged air conditioning unit that serves all levels of controlled space on your property fails, your whole facility is affected.WithVRF, a single floormay be all that suffers upon a failure.


VRF systems can use your existing ductwork or it can be


wall-mounted, surface-mounted or recessed.A retrofit of your existing property is do-able with VRF because it requires only core drilling and a piping layout. Also, don’t overlook attractive federal tax incentives and


your local utility incentives to help fund an upgrade to your HVAC system. Some of the players in this market include Pana- sonic/Sanyo, Mitsubishi, Daikin and LG. The SanyoVRF system, for example, was recently installed


in the new Carmel (IN) City Center, a 1 million-square-foot, $300-million multi-use development about 10 miles north of downtown Indianapolis. This installation – maybe the largest VRF project inAmerica today – is gaining national attention.The individual temperature control benefits and energy savings com- pared with othermore costly systems are reportedly unmatched.
