Cooling and Dehumidifying With A High Velocity System (SpacePak) and HRV
I'm mid-project on a 2000 sq ft addition to an existing Victorian in Toronto, Canada.
For all intents and purposes the 2nd and 3rd floor addition are independent of the main and basement below. We have radiant floors off a HE boiler. Very tight house with R30 walls and R60 roof.
For a variety of reasons we've elected to cool using a spacepak and heat pump. There is an independent HRV going from bathrooms to bedrooms.
My questions are:
- If I size the cooling to right at my heat gain calculation (or even a touch under) can I add a dehumidifier to help the system out on the design days and be more efficient on the shoulder days when dry is all the comfort we need.
- Can I introduce the dehumidification to my HRV ducting where it will run more hours and reduce the need to run my heat pump or air handler.
Any advise is greatly appreciated.
