Abstract
The open-face frames of electric heat modules used with a pair of centrifugal fans in a roof top type air conditioning unit are mounted with their upwardly open faces spaced downwardly away from the downwardly facing discharge opening of the fans, rather than up tight against the discharge opening, so that there will be a bypass of at least some of the discharge air from the fan around the module to reduce the resistance to air flow imposed by the module. The arrangement achieves a good balance between the use of relatively high watt density heater while avoiding undue resistance to air flow through the heater. The invention also provides a convenient module mounting arrangement in which the inboard end walls of the modules are supported in a complementary hook and eye arrangement with mounting straps depending from the sides of the discharge openings of the centrifugal fans.
