Abstract: Apparatus for dehumidifying or otherwise conditioning the air in a room has a cabinet housing a pair of units side by side. Each unit is essentially a conventional dehumidifier but has its evaporator and evaporator fan above its condenser, compressor and condenser fan and is separated therefrom to establish an upper evaporator section and a lower condenser section. The cabinet has outside air inlet ports opening into the upper and lower sections with each controlled by adjustable dampers. The cabinet also has a port through which air is discharged to the outside by the condenser fans. Separate conditioned air outlets open from the upper section into the room. In addition, the cabinet has ports in its ends to admit air from the room into the upper and lower sections and these are also provided with adjustable dampers.

Abstract: An automatic stoker boiler has a heat transfer compartment above a combustion chamber which is divided by a horizontal partition inclined upwardly from the rear end of the boiler towards but terminating short of the front end thereof to provide a restricted port between the thus established upper and lower portions. An endless link belt establishes the lower portion of the combustion chamber and hot gas conduits extend from the upper portion through the heat transfer compartment to the exhaust and which is provided with a draft inducing fan and adjustable damper. Underfire air under the control of an adjustable damper is introduced into the lower portion of the combustion chamber upwardly through the belt and air jets are delivered into the combustion chamber through the front end both above and below the port. A standby fluid fuel burner is located in the rear end of the upper chamber portion.
