Watch full course –

The course will provide a description of residential HRV (Heat Recovery Ventilator), ERV (Energy or Enthalpy Recovery Ventilator) and Smart DCV (Demand Control Ventilation) systems. Energy and humidity impact on a residence in different climatic regions and varying occupancy will be presented. The importance and value of active monitoring and control of indoor air quality will be discussed.

There is a growing demand for products and systems that can supply continuous fresh filtered outside air into an apartment or home while minimizing energy use. These products help avoid the need to open doors and windows that can lead to the loss of conditioned air within the home. Open doors and windows can also cause the entry of dust and insects, a reduction in security and exposure to adverse weather.

To help meet this demand, Fantech is introducing a new range of Energy Recovery Ventilators for residential and small commercial applications that will supply continuous ventilation into the occupied space.

The Aerofresh decentralized energy recovery unit that provides continuous fresh air to ensure a home feels fresh and comfortable to live in The system utilises an innovative ceramic core heat exchanger that delivers up to 82% heat recovery. . An Aerofresh unit can help improve the indoor air quality and ensure home occupants enjoy a healthier indoor environment. Aerofresh helps to prevent condensation and mould growth as well as maintain low concentrations of contaminants such as CO2 and VOCs.

Outside air coming in through windows and doors can be a major contributor to a home’s heating and cooling costs. The Aerofresh decentralized energy recovery unit provides pre-conditioned fresh air into the home which helps to reduce these energy costs by lowering demand on the heating and cooling systems.

How Aerofresh works
1. Aerofresh units are ideally installed in pairs and at maximum practical distance from each other
2. Both units are synchronised with each other and alternate their air flow direction from exhaust to supply every 70 seconds
3. This operation transfers the thermal energy from the exhaust air to the incoming fresh air, and therefore conditions the air before it comes into the home

When installed in pairs, the Aerofresh units can be wired in 2 ways:
1. As a balanced energy recovery system providing the home with pre-conditioned fresh air.
2. Wired to the exhaust fan or fans to provide make-up air when fan is activated. Aerofresh then reverts to balanced energy recovery when exhaust fan is switched off.
