Abstract: The invention discloses a humidifying device which consists in a thermally conductive casing which is adapted and correctly dimensioned to fit over a conventional electrical radiator without preventing it from heating the ambiant air simultaneously. The casing is destined to be at least partially filled with water, and upon the radiator generating heat, the water temperature will gradually increase and water will evaporate into the ambiant air through outlets in the top of the casing due to the heat being conducted through the radiator and casing to the water. The water vapor outflow rate can be selectively adjusted by means of a pivotable heat deflector or alternately by adjusting the distance between the radiator and the casing. A sponge member filled with bactericide is inserted into the casing and is submerged in water.

Abstract: A room humidifier in combination with a source of potable water and a source of heated fluidic material, such as a room hot water radiator, room steam radiator, room baseboard convector, remote steam boiler or remote hot water boiler. Potable water from its source is supplied to cover a heat exchanger in the humidifier to a desired level. Such potable water is heated by the heated fluidic material flowing through the heat exchanger, causing the formation of water vapor which collects within the humidifier. The desired relative humidity in the room is attained and maintained by control means which causes the flow of the heated fluidic material through the heat exchanger to form such water vapor and the control means causes a fan to operate to draw room air through the humidifier to render such room air moisture-laden and to blow such moisture-laden air into the room.

Abstract: A conventional baseboard radiator has a flat cover, an open metal box about the same width as the cover is supported on the cover in heat-conducting fashion. Support clips hook over the rear panel of the box and extend between the baseboard radiator and the wall to hold the box in position. A coarse screen is stretched across the top of the box and over the top of the ends. Tabs are struck out from the end panels of the box and are received by openings in the mesh to hold the screen in place.

Abstract: A humidification system for use with a baseboard style heater having a shallow, elongated convector casing, with extensive heat transfer surfaces therein, the system including a shallow evaporator tank combined with an external reservoir connected to the evaporator tank by way of a water level control. The evaporator tank is located above the fins and coils of the heater and has a deeply indented bottom portion to provide an extended heat transfer surface for rapidly heating a shallow layer of water within the evaporator tank. Convectional flow past the evaporator heat transfer surfaces is promoted by openings into the top of the evaporator. An adjustable cover on top of the evaporator regulates the air flow therethrough, and hence the degree of humidification.

Abstract: Air conditioning apparatus (10) comprising a cabinet (12) housing a heat exchanger (42) means (30) to draw ambient air into the cabinet, through the heat exchanger and through main outlet means (22), a steam generator (44) and a vapor mixing chamber (48) within the cabinet, means (50) to supply steam to the mixing chamber in which steam is mixed with ambient air to produce humidified air, and outlet means (54) through which the humidified air is expelled such that mixing with the conditioned air expelled from the main outlet is minimized.
