Hitachi SmartFlex™ VRF systems rank impressively high in the ratings that matter most for VRF technology
Hitachi SmartFlex™ VRF systems rank impressively high in the ratings that matter most for VRF technology: simultaneous cooling and heating efficiency (SCHE) and integrated energy efficiency ratio (IEER). The traditional measure of HVAC equipment, energy efficiency ratio (EER), measures system efficiency at full load. Using EER ratings may be appropriate for equipment that operates in a traditional cycle (fully on or fully off), but it is not appropriate for properly sized VRF systems, Since VRF systems have the ability to spend the vast majority of time at part load, reaching full load only on the hottest or coldest days. Hitachi SmartFlex™ VRF systems thereby excel against truer measures of efficiency and the following should be considered when evaluating solution choices:
VRF systems effectively address the ongoing challenge of climate control in buildings - balancing comfort and efficiency - by delivering just the right amount of heating and cooling to every space using no more energy than necessary. VRF technology achieves this balance by using DC inverter scroll compressors to save energy and avoid the wear and tear of frequent cycling. These compressors improve air conditioning efficiency by modulating refrigerant delivery to each specific zone to meet demand.
