Ventilation Systems

Joule supplies complete ventilation systems from mechanical ventilation & heat recovery, mechanical extract ventilation and demand control ventilation. Each ventilation system is carefully designed and installed so the correct ventilation rate and energy efficiency is at optimum level.

The ventilation systems supplied by Joule control indoor air quality by diluting and displacing indoor pollutants efficiently. Designing the correct ducting with each ventilation system ensures the highest efficiency with low energy use.

Demand Control Ventilation

Demand Control Ventilation

Demand Controlled Ventilation (DCV) is an automatic adjustment of ventilation equipment according to the choice of the occupant. DCV is a control method that modulates the volume exchange of fresh air or outside air into an enclosed space such as a home or office space by mechanical air conditioning equipment.

The InvaVent by Joule DCV system applies humidity sensitive technology to air inlets, grilles, and exhaust units located in rooms where humidity reflects the level of indoor pollution (lounge, bedrooms, bathrooms).

Mechanical Extract Ventilation

Mechanical Extract Ventilation

The InvaVent Mechanical Extract Ventilation systems are predominantly used in dwellings and apartments with five wet rooms or less (dwellings up to 300m² / 3200 sq ft). The sleek compact mechanical extraction ventilation unit is generally installed in the roof space and ducted to all wet rooms. The low energy unit runs at a low ventilation rate continuously extracting stale polluted air from rooms where the most moisture is generated e.g. kitchens and bathrooms.

Fresh air is normally provided from outside to habitable rooms by trickle ventilators fitted on windows, creating a flow of clean fresh air throughout the dwelling. The extract air is ducted from “wet rooms” to the outside and the extract rate is normally boosted at times when excessive moisture is being generated, such as when cooking or bathing.

Mechanical Ventilation & Heat Recovery

Mechanical Ventilation & Heat Recovery

The InvaVent Mechanical Ventilation & Heat Recovery systems by Joule takes control of the dwelling, improving health, wellbeing and lifestyle. Mechanical Ventilation with Heat Recovery removes stale damp air and replaces it with pre-warmed fresh filtered air creating a healthier environment with fewer pollutants.

Fresh air is supplied into the mechanical ventilation & heat recovery system via an external wall vent or roof cowl. The air distribution duct system supplies fresh air at the correct temperature to individual rooms as needed and vents the extract air to the outside.

Up to 96% of the heat is recovered from the extract air and transferred to the fresh air.
