I've be looking at the specs for Heat Recovery Ventilators (HRV).
They commonly state that they can recover 85% of the heat. How is that possible? To me you could only every recover 50% in a perfect situation because of the equal volume of airflow's. Won't the air temperatures just stop at...
Thanks I have read a bit but am still stuck... Where do I start?
I want to see how much freon needs to change state from liquid to gas to absorb about 22kJ of energy...
I don't know what to research or where to start but I would like to know much energy a compressed gas a requires to turn back into a gas if it is a liquid. Is there a term I should research and a formula like with specific heat?
The problem I am trying to solve is how much heat does X...
