Hi Folks:
I have modeled some PTHP with variable speed compressors.
I am getting simultaneous heating and cooling during the winter months. See attached spreadsheet.
I have not specified humidity control and the throttling range is .3. The heat set point is 72 and the cool set point is 75.
Any ideas?
Thank you,
