The pressure is on for facility managers during renovations. They not only face the usual day-to-day operational challenges but must also minimize the disturbances that construction can cause. If they don’t, occupants complain. The good news: Replacing an HVAC system or updating an old one doesn’t have to be just one more complaint-worthy disturbance. Variable Refrigerant Flow (VRF) systems are minimally disruptive during the installation process. Here are three reasons why:
SIMPLIFIED INSTALLATIONS VRF outdoor units’ small footprint have a profound effect: They can be transported in an elevator and can be installed in tighter spaces because they require less piping and duct space than conventional HVAC systems. A smaller footprint means fewer disturbances to the occupants – no cranes outside the window and no rooftop space lost to a condenser farm.
FLEXIBLE INSTALLATIONS Even building interiors enjoy a smooth retrofit experience with VRF. The ability to mix and match 11 indoor unit styles means each office, apartment, classroom or other space can be cooled and heated
by the unit that works best for that space. No need to install ductwork when a floorstanding ductless unit will work; no need to take up visual space with a wall-mounted unit when a ceiling-recessed unit will work. Occupants will barely notice their new system and it operates nearly silently!
LIGHTER WEIGHT VRF systems are up to 31 percent lighter than chilled-water systems, providing easier handling and the ability to distribute the weight across an existing structure. Alternatively, VRF outdoor units can
be mounted on the ground. This reduced need for structural support (compared to conventional HVAC systems) means occupants won’t be bothered by the noises and vibrations of heavy construction.
