I have decided on a counterflow heat exchanger with air to air properties.

I know the volume of the house, and the air change rate is 3 times this per hour.

I know the temperatures of Hot air in and Cold air in.

I also know or have calculated Specific heat Capacity, Density and Mass Flow Rate.

I have set my calculations up on a spreadsheet, however i am now stuck as some equations require Hot temperature out and cold temperature out.

Thanks in advance
