Ventilation systems with heat and moisture recoveryExtremely economical and quiet, yet large power reserves to have the best indoor air quality even at a large party. Is of course part of the basic equipment.
For 3 decades I have observed that ventilation systems with heat recovery almost do not spread because of absurdly high prices. Here I explain why a ventilation system, which every ventilation engineer would call “The mother of oversizing”, is the most economical solution and belongs to the basic equipment of a “GEMINI next Generation” house. 00:14 AustoBau Salzburg and Wels energy saving fair first seen in 1992 00:59 Absurd surcharge for comfort ventilation at prefab house manufacturer 02:06 Residential 30-year loan calculator 02:49 Would such an upcharge list be conceivable when buying a car? 03:43 Effect of pipe diameter on electricity consumption 05:14 Air exchange and efficiency diagram 06:29 Assumed efficiencies at 100 m³/h 07:12 Sunny dry cold -5° 20% outside - 18° 40% inside with 70 m³/h 09:00 Cloudy humid 2° 80% outside - 18° 40% inside with 70 m³/h 10:14 Sunny dry cold -5° 20% outside - 22° 50% inside with 100 m³/h 11:28 Cloudy humid 2° 80% outside - 22° 50% inside with 100 m³/h 11:41 Sunny dry cold -5° 20% outside - 25° 50% inside with 100 m³/h 13:29 Cloudy humid 2° 80% outside - 25° 50% inside with 100 m³/h 13:46 CO2 chart for 2 people, 165 m³, 0, 20, 50, 100, 200, 500 m³/h 15:21 CO2 diagram for 6 people 15:36 CO2 diagram for 16 people 16:37 Remove cover, behind it connections power and RS485 Modbus 16:57 USB to RS485 adapter for connection to smart home computer 17:48 Blower door test common for passive houses 18:24 Ventilation system in normal operation 18:40 Ventilation system as Blower door Test: much pressure difference, the house is tight 18:56 Very little pressure difference only: the house is leaking 19:13 Unwanted air exchange through leaks 19:52 Air risk defense mode: in case of nuclear accident and radioactive cloud 21:28 Behind the service door 22:55 End Music: Andy Mangele |
