Product Description:

Air2energy offer a range of heat and energy recovery ventilators, suitable for various residential and commercial/industrial applications including households, childcare centres, schools, industrial buildings/factories, and high humidity areas such as indoor swimming pools.

Heat recovery ventilators (HRVs) operate using a heat exchanger between inbound and outbound air flows. In winter for example, cool and fresh outside air is drawn into the building via exhaust fans. Simultaneously, warm, moist and polluted inside air is drawn through the HRV and out of the building.

As both air streams pass through the heat exchanger, a proportion of the heat from the warmer (outgoing) air is transferred to the cooler (incoming) air.

The result for the building is fresh, improved air quality, while reducing the required energy consumption and sizing of air conditioning units. A similar, but opposite, process occurs in summer.

Energy recovery ventilators (ERVs) are closely related to HRVs, but also transfer the humidity levels of the exhaust air to the intake air.

air2energy HRVs and ERVs optimise energy efficiency and are stated to provide heat/energy recovery up to 81% (residential) and 80% (commercial).

The systems can be used stand-alone, or in conjunction with HVACs to improve efficiency.

If used with a standard HVAC system with a Co-efficient of Performance (CoP) of 2.5-3, Venmar HRV and ERV systems could be expected to significantly raise this CoP to approx 5.5 (awaiting confirmation).They can also result in reduced size of HVAC system required.

High efficiency filtration: They also have optional high efficiency filtration of 90% (10-40 micron standard, but down to 1 micron).

This is sufficient to filter out most dust, PM10, PM5 and PM2.5s (carcinogenic fine particulates from diesel and other combustion processes), food smells, even most bacteria, moulds and large viruses.

Apart from removing pollutants, the main additional benefit of this type of electronic filtration is the low pressure resistance created (Hospital or HEPA grade filtration requires large amounts of energy to push air through extremely fine pores in the fitration media, whereas electronic filters do mostly the same task, and almost to the same level of perfromance, but without the high energy and maintenance costs of HEPA filtration.

Reduced pollution and dust of internal air also has additional benefit of reducing need for cleaning, and provides relief to dust and chemical sensitive individuals.
