Manufacturers of all sizes are introducing energy recovery ventilators (ERVs); heat recovery ventilators (HRVs); blowers; air curtains; high-velocity systems; and high-volume, low-speed (HVLS) fans that push the industry forward in response to a demand for more efficient ventilation systems.
At up to 93 percent efficiency, Ventacity heat recovery ventilators (HRVs) and energy recovery ventilators (ERVs) deliver fresh outdoor air within a few degrees of room temperature, reducing heating and cooling loads and HVACR equipment energy requirements by up to 50 percent.
Not that long ago, if a conversation centered on heat pumps, it was fairly safe to assume that the equipment referred to ducted, split-system, electric, air-source units. That assumption started to change a few years ago with the growing popularity of ductless heat pumps.
The challenge of prioritizing IAQ and using high ventilation rates is to cost effectively treat the fresh outdoor air for temperature and humidity. For the past 15 years, Drury Southwest has utilized rotary energy recovery wheels manufactured by Airxchange Inc. in new hotel constructions and HVAC system renovations.
Selling end-users just an energy recovery ventilator (ERV) without realizing the options or wheel’s long-term performance benefits cheats a facility out its full energy-saving potential, which is ironically the premise for energy recovery in the first place.
Energy Recovery Ventilation Tool Quantifies the Benefits
