System Description
The whole house ventilation system has been professionally designed and
manufactured in Ireland by ProAir Heat Recovery Ventilation Systems Ltd. It has been
installed and tested in accordance with the relevant EN standards and in conformity to
Part F and B of the DOE SI 497 of 1997 & DOE SI 581 of 2002 Regulations.
It has been designed to:
• Continuously ventilate all the rooms in your house in a controlled manner to give a
healthy environment.
• Remove moisture & odours thereby preventing condensation build-up, mould
growth etc.
• Provide a draught free environment with the required amount of filtered fresh air
for the occupants.
• Minimise the energy losses by recovering the heat from the extracted stale air &
transferring up to 90% of this heat to the incoming fresh air.
The principle behind energy efficient whole house ventilation is to continuously
supply fresh air & extract stale air, such that the air is changed in the house around ten
times per day. Air is supplied to living areas (bedrooms living room) and extracted
from service areas (bathrooms, kitchen, utility).
It is normal to feel a very slight air movement at supply points. This air will be within
2 degrees of the average temperature of your house (17-19°C) but may still feel cool.
This is because of the movement of the air and because your body temperature will be
normally around 37°C.
The temperature of the supply air is dependant on the average of all the extract points.
If one extract point is at low temperature (because a bathroom window was opened in
winter and forgotten) then this will bring down that average and cause supply air
temperature to be low throughout the system.
The ProAir system in your house is the PA 600 model shown in fig.1 It is designed to
operate 24 hours / day, 7 days/week, running at a low speed while the house is
normally occupied. At other times when there is higher than normal water vapour
generated (cooking & showers) the system can be triggered, extract higher volumes of
air, for a pre-defined period.
