Hello, I am having difficulty in calculating F and was wondering if anyone could help. F is the heat flux in W/m2 between the Heat Pump-House system from the Atmosphere. Now I have the Energy 'lost' from the house walls into the atmosphere. If we don't consider any other parameters, this energy would be the same exact amount of energy that I need to add into the House to maintain a constant temperature. By looking at some of the Heat Pump specs and by knowing that the Coefficient of performance is 2.5 I should be able to calculate the energy heat has to transfer from the outside into the inside. The difference between the heat flux lost from the House into the atmosphere and what the heat pump extract from the atmosphere would give me the NETT COOLING of the atmosphere due to the Heat Pump. Which is my F in W/m2. Now I'm a bit confused on how I go and do that really... Im fine with the sentence before the bold text but then I just get lost... Thanks John
