Energy-recovery ventilation is more efficient

Panasonic’s latest energy-recovery ventilation units are 6% more efficient than earlier products, an improvement that is due to a new counter-flow heat exchanger to replace cross-flow elements. When installed with an air-conditioning system, the air-conditioning load is reduced by 20% compared to regular ventilation. The improvement translates to a reduced vertical profile of the heat-exchange element, from 287 to 230 mm, which also makes the units quieter in operation. The compact counter-flow element has a plastic frame and large air passages to resist clogging. The element and non-woven cloth filter require cleaning just once or twice a year to maintain optimum efficiency. Six models provide ventilation rates from 250 to 1000 m3/h. They are 270 or 338 mm deep, according to capacity. Noise levels are less than 32 dB(A) for units up to 500 m3/h on the high setting, with 37.5 dB(A) for the 1000 m3/h model.
