I have an old box type air conditioner in our family room that I installed about 15 years ago.
At the time the ratings were in HP. It is a 3 HP unit,probably the biggest you could get at the time.
The family room is roughly 60m2.and it cools this room effectively
Looking at swapping it over for a split system only because of the noise factor.
When I look at the conversion tables they tell me that 3HP = 2.2 KW.yet the sizing tables tell
me I need a 6-7 KW unit to cool this area.The say that 2.2 KW unit is ok for small bedrooms,study's etc.
Whats going on?
