  How does it work? 

Mechanical Ventilation with Heat Recovery (MVHR) provides fresh filtered air into a building whilst retaining most of the energy that has already been used in heating the building. Heat Recovery Ventilation (HRV) is the solution to the ventilation needs of energy-efficient buildings. Properly fitted into a commercial setting, an HRV system provides a constant supply of fresh filtered air, maintaining the air quality whilst being practically imperceptible. 
MVHR works quite simply by extracting the air from the polluted source within the building e.g. office, warehouse, production, canteen/kitchen, toilets, etc. The extracted air is taken through a central heat exchanger, where the heat is recovered into the supply air. This works both ways as if the air temperature inside the building is colder than the outside air temperature, then the cool air is maintained in the building.
