Revision history [back]

I design a samll house, using OpenStudio 1.7.2, with a ground source heat pump (GSHP) for space heating, cooling, and hot water use. But I got a serious trouble in HVAC modeling. Overall scheme is like this:

(1) the main system is GSHP (2) space conditioning is supplied by underfloor radiant heating and cool air from the ceiling. That is, water heated by GSHP circulates underfloor tubes, and chilled water coil exchanges heat with outdoor air to cool the air during summer.

I think water-to-water GSHP is desirable for heating, and water-to-air for cooling. However, I have no idea of how combine those water-based loop and air loop to support for a single thermal zone. And please let me know if you possibly know how to construct GSHP with radiant floor heating without implementing "district heating or cooling" plant object.
