Re: [TRNSYS-users] Air to Air Heat Pump

[David BRADLEY <d.bradley@tess-inc.com>]

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

Hello Trnsys users,

I would like to simulate an air to air heat pump for a 804m² room by using type 954  with the following parameters to have an room temperature equal to 20°C
10 kW Rated heating capacity
5000m³/h Total air flow rate
No auxilary heating system.
Outlet air temperature : 37°C

What would be the Rated heating power of such heat pump ?

Thank you for any kind of help in advance.

Rémi
