ABSTRACT:
A zoned HVAC system for a building is provided with three control zones: an internal zone (14), a perimeter zone (16) and a skin zone (18). The internal zone (14) provides cooling of internal heating loads from equipment and personnel as determined from internal zone (14) thermostats (43, 46, 48). Perimeter zone (16) provides cooling against interior and solar heating loads, with thermostats (51, 52, 53, 54) controlling associated sectors dampers (56, 57, 58, 59). The skin zone (18) provides both heating and cooling against thermal transmissions through the building exterior (10). Each skin zone sector (30, 31) is assigned to a plurality of perimeter zones (24, 25, 26, 27). Operation of a skin zone sector (e.g. 30) is effected by a control box (e.g. 64) receiving inputs from perimeter zone thermostats (e.g. 51, 52) with a control output functionally related to the perimeter zone sector with the lowest cooling demand.
