Why combined heating and ventilation systems are essential

  • 27 Mar 2015

Nordair Niche has provided McDonald’s Restaurants with an effective combined heating and ventilation system to improve air circulation and quality

The importance of good ventilation

Good ventilation is important in commercial buildings: without effective air circulation, pollutants, gases and bad odours can build up.

Mould can also begin to grow, compromising the health of employees and making environments unhygienic.

The quality of air can also deteriorate when production processes are underway.

For instance, automotive manufacturing processes can produce oil haze and chemical processes can create unpleasant vapours.

The Control of Substances Hazardous to Health (COSHH) regulations require employers to to manage substances that can have an impact on their worker’s health.

Effective ventilation acts as an effective solution: it can remove lingering dangerous chemicals and reduce the risk of mould forming.

Combined heating and ventilation systems

Combined heating and ventilation systems can improve air quality whilst optimising energy efficiency. Nordair Niche has suggested that these systems can improve air circulation in commercial buildings.

The company’s direct and indirect gas fired units, for example, can provide a building with both fresh and warm air.

Direct fired units have been designed to supply the right amount of fresh air necessary to meet the changing requirements of a building.

Working on a patented air recirculation system, the units are also able to simultaneously maintain a constant supply of fresh air into the burner.

The systems’ dampers automatically adjust to provide the required amount of tempered outside air.

The units are also able to pressurise the air inside the building to distribute it evenly and reduce the creation of ‘cold spots’.

Heat recovery is used within the the ventilation systems to reduce running costs and CO2 emissions.

Ventilating McDonald’s Restaurants

Nordair Niche recently collaborated with Mitsubishi Electric to create a heating and ventilation and cooling system for McDonald’s Restaurants across the UK.

Nordair Niche’s new Air Handling Unit was used for cooling, heating and ventilation: after installation, each McDonald’s site cut its running costs by over £4,500.

It also helped the restaurant chain to cut its carbon emissions and reduce its energy consumption by around 35%.

The units were combined with Mitsubishi Electric’s Air Source Heat Pumps to ensure that the ventilation systems operated as efficiently as possible.

As well as reducing running costs, the energy efficient systems were also able to provide McDonald’s customers with a consistent and comfortable temperature.
