1.0 APARTMENT VENTILATION

Note: It is strongly recommended to read the Operational Guide for this chapter.

Figure 2 Ventilation Schematic

Cilantro has installed a Nuaire MVHR Ventilation Unit in the Apartments, Located in the Utility

Cupboard.

The Home Air Circulation Fan Unit moves air around your property at such a low level that you never

feel it, but it takes all the stale air from inside your house and replaces it with clean fresh air, 24

hours a day, 7 days a week. Your home is ventilated without the need to open windows which can

let in noise, fumes and can compromise security.

It will supply filtered fresh air to the living areas and will extract air and fumes from the wet areas:

Bathrooms, En-suites, Kitchens and Utility Cupboard. The fresh air supply will be pre-heated through

the MVHR heat exchanger element using the heat on the extracted air (previously pre-filtered).

When the integrated humidity sensor detects a higher humidity than the one set up in the system, it

will turn on the Boost extract fan in the bathroom & Kitchen areas. The boost extract fan will remain

on until the humidity has gone below the setpoint. The unit will also turn into Boost mode when

light switches in Bathrooms and Kitchen are turned on.

 MVHR supplies & extracts air

continuously at a low rate with

boost facility to extract pollutants

and supply fresh outdoor air at a

higher rate as required

 Can be controlled either; -

Manually via single or multiple

switches - Automatically, typically

via humidity or other sensors These

should be clearly marked and

located in an accessible location

in or near the wet rooms -

Normally the MVHR unit is sited

remotely in a loft space or

cupboard and ducted via rigid

duct to outside air using the most

economical route

 Replacement

introduced into bedrooms and

living

areas

therefore background ventilators

in windows are not required
