Effective, compliant ventilation of multi-occupancy rooms is simplified with an innovative concept from Gilberts of Blackpool.
The air movement specialist’s Mistrale Fusion (MFS)Terminal delivers optimum internal air control for less than £5.00/room/annum1. The initial single-sided through-structure unit provides a one box, stand-alone solution, requiring no additional ductwork or plant. The Mistrale MFS is, says Gilberts, the first in a new series that revolutionises energy-efficient ventilation in non-domestic buildings.
“There is nothing else like it on the market,” says Gilberts’ Sales Director Ian Rogers. “In one unit, it ticks all the boxes in terms of natural ventilation criteria in multi-occupancy rooms such as classrooms.”
Installed through the external façade or window, Mistrale MFS mixes internal and external air to ventilate the internal space. A mixing damper within modulates airflow to allow the new, fresh air to mix with the warm exhaust air, thus extracting its heat without the need for an exchanger. The integrated low energy fan energises to blend the internal air, ensuring an even distribution of airflow, with control over temperature and CO2 levels within, and maintenance of a comfortable internal environment for occupants.
Just 2 no Mistrale MFS128 single-sided units will ventilate a standard 32 person classroom, achieving the 8litres/sec/person fresh air required by current Department of Education Building Bulletin (BB101) and PBSP guidelines.
Each unit also achieves relevant acoustic considerations: its operational ‘noise’ is less than 30dbA, and it has been engineered to absorb external noise to keep within the classroom criteria required by BB93.
Gilberts has further taken care to attain compliance with Building Regulations Approved Document L: Mistrale MFS attains air leakage better than legislative requirements- 5m3/HR/m2, and a U value of 1W/m2/°C. As with all Gilberts’ ventilation solutions, it delivers efficient weather performance via its bespoke louvre system.
