The HRV illustrated above is shown installed in the roofspace, (sourcing OUTDOOR AIR). Many homes where ventilation is to be retrofitted, have space problems – between two story floors, flat roofs, etc, presenting what appear to be insoluble problems with regard to installing an HRV. CLEANAIRE has a range of over 22 models of HRVs to suit every home.
We have models for …..walls, outdoors, rooftop, underfloor, basement, etc -- whatever the problem we are almost certain to have a solution.
CLEANAIRE HRVs are designed to ventilate homes with 100% fresh outdoor air, at the rate recommended in NZ Standard 4303 "Ventilation for Acceptable Indoor Air Quality" ie one air change every 3 hours. Each model has two ultra-quiet fans, one to exhaust stale humid air and another supply fan to replace exhausted air with dry warm outdoor air. Heat from the exhaust air stream is "captured" by a heat exchanger and recycled to preheat the incoming cold, fresh outdoor air. The fresh outdoor air becomes dry when it is warmed by the heat exchanger. Introducing fresh, warm, dry air into your home evaporates and controls condensation (similar to a motor car windscreen warm air demister, or hair or clothes dryers).
Polluted, damp indoor air is continuously exhausted and replaced by 100% fresh outdoor air. Excess humidity is positively exhausted to outside with the foul air and, in some conditions condenses on the heat exchanger plates (exhaust side only) to be disposed of by the HRV drain.
Continuous trickle ventilation with fresh, warm outdoor air dilutes indoor air contaminants, which are positively removed by the exhaust fan. The result is an indoor environment that is always fresh and healthy.
The CLEANAIRE HRV performs best when winter conditions are at their worst, day and night. In an average (heated) home, additional heat (or sunshine) is unnecessary.
