Dear TRNSYS users,

Thanks for your help!

Only the specific heat capacity is set in the collector module, but if I want to use R134a, the working medium will undergo a phase change in the collector, and the specific heat capacity will also change.

I want to ask for help, how to use this working medium in a collector for a direct expansion solar heat pump?

Best regardsŁĄ
