Abstract: A purification dehumidifier includes a housing, a fan, a dehumidifier assembly, and a purifier assembly. The housing includes an air inlet, a dehumidified air outlet, and a purified air outlet. An air duct in communication with the air inlet, the dehumidified air outlet, and the purified air outlet is formed in the housing. The fan is arranged in the air duct and configured to introduce an airflow into the air duct from the air inlet and blow the airflow in the air duct out from at least one of the dehumidified air outlet or the purified air outlet. The dehumidifier assembly is arranged in the air duct and corresponding to the dehumidified air outlet. The purifier assembly is arranged in the air duct and corresponding to the purified air outlet.

Abstract: An HVAC system includes an indoor heat-exchange coil disposed between a supply air duct and a return air duct. A damper is disposed in a re-circulation duct and is moveable between an open position and a closed position. A controller is configured to determine if the HVAC system is operating in a heating mode or an air-conditioning mode. Responsive to a determination that the HVAC system is operating in the air-conditioning mode, the controller is configured to determine if the variable-speed indoor circulation fan is operating at a minimum speed and if the relative humidity measured by the humidity sensor is above a pre-determined threshold. Responsive to a determination that the variable-speed indoor circulation fan is operating at the minimum speed and the relative humidity of the enclosed space is above the pre-determined threshold, the controller signals the damper to move to the open position.

Abstract: An air channeling sub-system includes a mechanical cooling section and a direct evaporative cooling section. The direct evaporative cooling section is located downstream from the mechanical cooling section. Cooling air is channeled through the air channeling sub-system and into a room that receives supply air from the air channeling sub-system. If a first set of control conditions is met, the air channeling sub-systems is operated in an economizer mode. The economizer mode includes controlling an amount of return air that is blended with outside air and channeling the blended air through the direct evaporative cooling section to evaporate water into the blended air to control humidity. If a second set of control conditions is met, the air channeling sub-system is operated in a free cooling mode. The free cooling mode includes channeling cooling air to the room while the mechanical cooling section and direct evaporative cooling section are shutdown or inhibited from operation.

Abstract: A method for operating a gluing system (10) for gluing blanks for producing and/or packaging cigarettes or other smokable objects, in which the blanks are conveyed along glue valves (11) of the gluing system (10), in which case, in order to control and/or regulate the glue valves (11), a superordinate master controller (13) respectively transmits values of at least one control and/or regulation parameter to individual controllers (15) which are assigned to the glue valves (11), are subordinate to the master controller (13) and are each connected to the superordinate master controller (13) via a suitable data connection, the subordinate controller (15) using said values to control and/or regulate the glue valve (11) assigned to it.

Abstract: A heat exchanger comprises: a first medium inlet operable to receive a first medium into the heat exchanger; a first medium outlet operable to expel the first medium from the heat exchanger; a second medium inlet operable to receive a second medium into the heat exchanger; a second medium outlet operable to expel the second medium from the heat exchanger; and a plurality of parallel tubes running from the second medium inlet to the second medium outlet operable to carry the second medium from the second medium inlet to the second medium outlet, the plurality of tubes including: a first section of a first plurality of tubes, at least one of the first plurality of tubes having a first diameter, situated so that the first medium first flows from the first medium inlet over exterior walls of the first plurality of tubes and through gaps between the first plurality of tubes; and a second section of a second plurality of tubes, at least one of the second plurality of tubes having a second diameter that is different

Abstract: An improved humidifier system for adding humidity to an air stream of an HVAC system. The humidifier system includes an air path that is configured to accept air from a first HVAC duct and return air to a second HVAC duct. A damper is disposed in the air path to selectively substantially block the flow of air in the air path, or to substantially not block the flow of air in the air path. In some cases, the damper may be a motorized damper, and the humidifier system may include a controller that is configured to cause the motorized damper to not substantially block the flow of air in the air path during a call for humidifier operation, and to substantially block the flow of air in the air path after the call for humidifier operation ends. Alternatively, the damper may be manually actuated, and an HVAC controller may be configured to notify when the damper should be moved (e.g. between seasons).

Abstract: In an air feeder for supplying air with a predetermined temperature and humidity into a cup in a resist coating unit provided in a coating and developing system, a cooling section, a by-pass, a heating section, a humidifying section, and a blower are provided. 55% of introduced air is cooled in the cooling section, 45% of the introduced air passes through the by-pass, and mixed air of the cooled air and the air from the by-pass is heated in the heating section and humidified in the humidifying section, thereby enabling energy-saving and space-saving temperature and humidity control.

Abstract: An apparatus for maintaining an enclosed space proximate a selected comfort level, and for conserving utilities, the apparatus comprising a housing in communicating relation with the enclosed space and the external environment and having an evaporative cooler for cooling the enclosed space and having a predetermined operating efficiency, and a spaced apart air conditioner for either selectively cooling or heating the enclosed space, having a baffle that restricts airflow to the air conditioner and an operating efficiency different from the evaporative cooler, and a control mechanism for automatically and selectively switching back and forth from operation of the evaporative cooler to the air conditioner in response to ambient conditions of the external environment and the operating efficiencies of the evaporative cooler and the air conditioner.

Abstract: An air dehumidifying and conditioning system (20) draws incoming air (32) through a fan (40) and uses heat from the fan (40) and fan motor (48) to heat air discharged from the fan. The system then divides air discharged from the fan into a supply stream (50) and a scavenge stream (52). The supply stream is passed through a pre-cooler (60A) and an air cooler (60) for cooling and dehumidification. If necessary, the scavenge stream is heated with a pre-heater (62A) and a supplemental heater (62). The dehumidified air of the supply stream (50) is then heated by passing through a heat exchanger (80), with the heating by the heat exchanger being accomplished using the scavenge stream (52). Should no heating, cooling, or dehumidifying be required, a bypass stream (54) formed from the scavenge stream (52) is transmitted to the conditioned space.

Abstract: A room dehumidifier includes a closed refrigerant cycle apparatus with an evaporator coil inclined at 20 from vertical on an air inlet side of the dehumidifier, which also includes openings in the cabinetry to allow a substantial portion of inlet air to bypass the evaporator coil, a fan and orifice plate arranged downstream of the evaporator coil, bypass openings to draw air through the cabinet, and a condenser coil arranged vertically on an outlet side of said fan. The fan blows air through the condenser coil and out back side louvers of the cabinet. A drip bucket is located beneath the evaporator coils and a compressor is located beneath the condenser coils.
