I'm wondering if anyone can offer some advice on the best approach to get hot water for slab heating (say, 25C) in winter, and chilled water for dehumidication and slight slab chilling in the summer from an air source heat pump. The project is a small (10,000 sq.ft.) commercial building. We'd be best to size off of chilling capacity of 25 tons, which will require some supplemental heat (likely oil-fired boiler) as heating exceeds cooling in our climate. Anyway my problem is that the project's HVAC engineer has experience only with air source heat pumps that connect to air handling units and is a loss as to what to connect to generate heated/cooled water. I'd appreciate any direction.
