  • the fan system includes a housing communicating with a coiled passage.
  • the housing has an intake and an outlet each with a mouth, the mouths of the intake and outlet being oriented substantially 180° from one another.
  • a centrifugal scroll caged blower is mounted in the housing and an electric motor is connected to rotate the blower.
  • Baffles are provided within the housing for directing air in separate paths through the housing intake to an inlet of the blower and from the blower through the housing outlet, the flow of the air through the housing mouths lying in substantially parallel planes.
  • US 3 050 961 A describes a refrigerator including insulating means enclosing a blow freezing compartment and an above freezing compartment, means forming an evaporator compartment separated from said compartments containing an evaporator portion, means for circulating air from said below and above freezing compartments through said evaporator compartment in heat transfer with said evaporator portion and in commingling relationship and returning the cooled air to said above and below freezing compartments, said circulating means including means for proportioning the circulation of the air to maintain said below and above freezing compartments at temperatures below and above freezing respecitvely, and cooling means for precooling said air circulating from said above freezing compartment prior to its commingling with said below freezing compartment air.
