I'm looking for design suggestions of ventilation for my house. I'm not a HVAC pro, but former contractor, more than capable of building/installing anything, but need some approach/design guidance. Here's the context:
I have a typical 1960's ranch house located in coastal SF Bay Area. In a recent remodel I installed radiant floors, new windows and doors, and spray foamed most of the envelope. We have no AC and no mechanical ventilation, except bath fans. I have not tested how tight it is, but it gets stuffy fairly quickly when closed up, which is admittedly rare -- temperate climate, kids and dogs coming and going, doors and windows often left open, etc. It's a totally open plan, basically one long room, and a wing with two bedrooms and baths which have doors, but no other interior walls in the house. Thermostat is fixed at 65 and it's generally perfectly comfortable.
There are three ventilation enhancements I'd like however, and I'm wondering if I can do it with one system. First, I'd like a little forced ventilation in the bedrooms -- they get stuffy when the doors (interior) and windows are closed, which isn't often, but still it would be nice. Second, I'd like make-up air for range hood. Third, I'd like whole house air during the occasional hot summer evenings. The pattern here is that when it's hot it can be 85-90 in the day, but by 9pm it's almost always dropped to 60 or less and blasting outside air in would cool effectively.
I've looked at off-the-shelf balanced ventilation systems, but there are not many plain systems (non ERV/HRV). I don't think I need the added complexity of heat recovery in my climate and lifestyle. And of course none of them qualify as make-up air for my 1000cfm range hood.
So I was thinking, can I do something like take a Fantech MUAS 1600 (14" EC inline fan, filter, motorized damper, controls) and duct it to a couple large'ish registers in the kitchen and the living room (which are just either end of one room about 16'x60'), and with a couple small branches to the bedrooms, and then run it at very low speed always on, targeting balanced flow with three always on 50cfm bath/laundry exhaust fans, and then crank it up for range make-up and hot evening cooling.
Is this plausible?
