Laying out mini-splits for a new home
I have a new home in the design stage and have been working with with my HVAC sub and the wholesaler to layout and locate mini-splits for the project. The house will be 2550 sq.ft. on a slab with R40 walls, R75 ceiling and very tight. We are in zone 5, floor plan is attached. We will be installing an ERV for fresh air.
The HVAC guy and the wholesaler want to put a head in each bedroom as well as the entry, office, family room and great room and run them off of 2 separate outdoor units. Their concern is to provide uniform temps throughout the house.
I am concerned that we are putting more equipment in than is necessary. Most of the projects I have seen discussed in these forums have used fewer heads.
Are there any standards for laying out these systems? How are bedrooms normally handled? Any general advice? (especially from those who have lived with this type of system)
Your comments will be appreciated.
