Introduction 

 

The  Brookvent  aircycle  1.1/1.2  is  an  extremely  compact  and  highly  efficient  Mechanical  Heat 
Recovery Ventilation (MHRV) system, specifically designed smaller dwellings with restricted space.  
 
The  system  should  be  run  continuously  24  hours  a  day,  and  should  only  be  disconnected  by  a 
competent person during service or maintenance. 
 
Heat  Recovery  ventilation  works  best  in  new  homes,  which  are  extremely  airtight  and  have  high 
efficiency  ratings.    These  dwellings  require  a  high  level  of  fresh  air  to  ensure  a  healthy  living 
environment. 
 
The  system  works  by  drawing  stale  air  from  ‘wet  rooms’  such  as  Bathrooms,  WC’s  and  Kitchens, 
recovering  up  to  90%  of  the  heat  from  this  air  using  a  highly  efficient  heat  exchanger,  before 
expelling  the  waste  air  outside  the  home.    At  the  same  time,  fresh  air  is  drawn  into  the  home, 
filtered  and  warmed  by  the  recovered  heat  and  supplied  into  the  ‘habitable  rooms’  such  as 
bedrooms, dining rooms and living rooms.
