[TRNSYS-users] Air to Air Heat Pump

[David BRADLEY]

Rémi,
   a traditional air-to-air heat pump typically has a coefficient of 
performance (COP) of about 1.5 to 2 meaning that for every unit of 
energy you put into the compressor you deliver about 1.5 to 2 units of 
thermal energy to the air stream. So very roughly, your 10kW heat pump 
would have a rated heating power between 5 and 7kW.  These are very 
rough numbers, however and I would highly recommend that you go to the 
website of a heat pump manufacturer and find some product literature for 
a device with a 10kW heating capacity to see what the heating power 
(really the compressor power when in heating mode) is.
Kind regards,
  David
