Airconditioning for the quality of living.

Heat Recovery Ventilator will provide

  • fresh air into a building,
  • extract stale air from the building,
  • filter the fresh air entering the building to remove pollutants,
  • recover heat from the stale air using a heat exchange core,
    and transfer the recovered heat to the incoming fresh air.

Ventilation

The new homes of today have greatly reduced levels of natural ventilation which reduces heat loss, positively contributing to the energy efficiency of the property. However, a lack of proper ventilation can lead to a build up of contaminants that can affect the health of a building’s occupants. The need for ventilation in new homes is so important that a section of the building regulations (part F) is devoted solely to this issue. Part F recognises the role to be played by heat recovery ventilation to not only meet the ventilation requirement but also to comply with the energy efficiency requirements of the building regulations.
Each and every one of us requires fresh air to survive, with each person exhaling between 10 and 75 litres of carbon dioxide and 175 grammes of water vapour per hour. A family of four produces between 10 and 15 litres of water vapor each day through cooking, washing and breathing. Dust mites have proven links with over 80% of asthma cases and thrive when humidities are high. What’s more within a typical home there are traces of ammonia, acetic acid, methane, nitrogen monoxide and formaldehyde from cleaning products and building materials.
Unless ventilation is added these contaminants will linger within the home and will affect both the health of the occupants and can lead to damage to the fabric of the building itself. A well designed fresh air system can reduce these levels significantly, replacing contaminants with clean fresh air.

HRV stands for Heat Recovery Ventilator. It is a technology that has been used for the last 40 years worldwide to provide high quality indoor air into buildings for the benefits of the occupants. HRV technology is used for commercial and industrial buildings as well as residential buildings.

A genuine HRV system will provide the following:

  • fresh air into a building,
  • extract stale air from the building,
  • filter the fresh air entering the building to remove pollutants,
  • recover heat from the stale air using a heat exchange core,
    and transfer the recovered heat to the incoming fresh air.

HRV systems are systems delivering fresh filtered air from outside the building (external to the building and associated roof space) to living and bedrooms and extracting stale air from high moisture areas such as bathrooms, kitchens and laundries. Typically, an HRV is able to recover 70 to 90 percent of the heat from the exhaust air depending on the type of exchanger and transfer it, via the heat exchanger to the incoming air.
