SUPERMARKET ENVIRONMENTAL CONTROL SYSTEM ABSTRACT OF THE DISCLOSURE An air temperature regulating or conditioning control apparatus for use in a space having one or more refrigerated display fixtures. The fixtures have an open refrigerated display zone separated from the conditioned room space by one or more planes (curtains) of refrigerated air substantially lower in temperature than the conditioned room space, which absorb energy from the room air adjacent these planes thereby causing it to be cooled. The apparatus comprises a housing having a return air chamber and a make- up air chamber isolated from the return air chamber. Each of these parallel chambers has an outlet connected to a mixing compartment for mixing the conditioned air received from both chambers. An air moving means is connected to the mixing compartment for displacing the mixed conditioned air through air flow convection ducts back into the space. Each of the chambers further has an air intake or inlet, a filter section and a cooling section. The inlet of the return air chamber is supplied primarily with air cooled by the refri- gerated display fixtures. The room space is maintained at a substantially constant temperature throughout unaffected by the refrigeration effect of the display fixtures upon the room space air.
