The HVR Zero sets a new benchmark for the future generation of low energy hybrid ventilation systems that integrate heat exchange ventilation strategies. It provides natural ventilation, hybrid mixing ventilation and low energy mechanical heat recovery ventilation in one compact unit. The system operates completely autonomously to ensure optimum indoor air quality with the lowest possible energy use - in terms of both the energy consumption of the ventilation system and overall building energy usage.
The HVR Zero is a Hybrid Ventilation unit that combines the benefits of natural ventilation with additional support from fans in a traditional mechanical ventilation system.
The system comprises of an intelligent and fully automatic control system coupled with a low energy ventilation system which switches between operational modes dependent on season, external/internal temperature conditions and indoor air quality (IAQ). At all times the system will utilise natural ventilation as its primary mode, then as the internal room temperatures or CO2 concentration increases, the low energy internal fan will operate to provide fan assisted natural ventilation at variable speeds dependent on the internal room conditions. System automatically provides secure night time cooling through natural ventilation opening or fan assisted if required. Winter ventilation automatically modulates dampers to mix re-circulated air with external air to ensure optimum ventilation temperatures.
