Combined heat and power - Thermal and Power ratio

Posted: 09 Mar 2011 04:36 AM PST

Hi Guys!!

I was wondering what happens when you are trying to design a chp system that will be installed on a building that has a thermal to power ratio that is transient. How do you match the optimum size machine/technology if in some months you need to supply more power and in others more heat?

Thanks
