*1: fresh air (from outside the house); can be either cold or hot; must atleast be o°C or above; at days this is not reached the air entering via this pipe must be heated, see [http://en.wikipedia.org/wiki/Heat_recovery_ventilation here].
*2: cold stale air (from inside the house). This cold, humid and smelly air is vented outside the house
*3: warm stale air (from inside the house)
*4: purified (no longer humid, smelly) warm air (from inside the house)
*5: heat exchange core
*6: circulation fan (placed at high up to prevent water damage)
*7: circulation fan (placed at high up to prevent water damage)
*8: air filter (removes smells and water from the indoor air)
*9: air filter (removes pollen, dirt and water from the outside air)
*10: sloped bottom; condensate drips along this bottom plate towards the drain
*11: sloped bottom; condensate drips along this bottom plate towards the drain
*12: drain
