摘要:
A humidifier is disclosed which includes a desiccant wheel (54), and a heat exchanger adapted to heat-exchange air dehumidified in an absorption chamber (60) with air introduced into a regeneration chamber (70). The heat of the air dehumidified in the absorption chamber (60) can be used to increase the temperature of ambient air introduced into the regeneration chamber (70), thereby reducing the load of a heater (56) to heat the temperature of the ambient air introduced into the regeneration chamber (70), and thus, achieving a reduction in the power consumption of the heater (56).

Der Rotationswärmeaustauscher weist ein Gehäuse (1) auf, in welchem ein Rotor (5) gelagert ist. Dessen Luftkanäle (6) tragen eine sorptive Beschichtung, die der Feuchterückgewinnung dient und im wesentlichen nur Wassermoleküle aufnimmt. Ferner ist eine gehäusefeste, ringförmige Scheibe (10) vorgesehen, die eine umlaufende, federartige Lippe (11) aufweist. Letztere drückt abdichtend gegen eine axiale Fläche eines auf dem Rotor (5) angeordneten Ringes (7). Eine Trennwand (2) teilt das Gehäuse (1) in einen Zuluft- und einen Abluftkanal (3,4). Die Kanten der Trennwand (2) dichten gegen die Stirnflächen des Rotors (5) ab und tragen hierzu jeweils eine Leiste (13) aus geschlossenzelligem Schaumstoff, die mit einem Band (14) aus elastischem, abriebfesten Kunststoff beschichtet ist. Das Band ist breiter als die Leiste und kann sich an den Rändern aufwölben. Auf der dem Ablufteintritt zugewandten Seite des Rotors bildet die Trennwand (2) eine Doppelspülkammer (12). Der Rotationswärmeaustauscher verhindert Stoff- und Geruchsübertragungen und genügt höchsten hygienischen Anforderungen.

The outgoing air discharged from said room (11) is heated, flows through the adsorption dryer (3) for regeneration and is discharged as discharge air. The inventive device comprises a cooler (6) that is arranged in a fresh air channel (13) between the room (11) to be conditioned and a regenerative heat exchanger (5), and is mounted downstream of the adsorption dryer (3) in the direction of the air flow. The cooler (6) is linked with a cold source that has a medium level of coldness.

摘要:
A method for conditioning air for an enclosure in which a supply air stream is cooled with a refrigerant system containing a variable compressor by passing the air over a cooling coil to reduce the temperature thereof; the thus cooled supply air stream is then passed through a segment of a rotating desiccant wheel under conditions which increase its temperature and reduce its moisture content, and then delivered to the enclosure. The desiccant wheel is regenerated by heating a regeneration air stream with the condensing coil of the refrigerant system, and then passing the heated regeneration air stream through another segment of the rotating desiccant wheel. At least one condition of the supply air stream, the regeneration air stream, and/or the refrigerant system is sensed or monitored and the output of the compressor is controlled in response to the sensed condition.

A low-humidity working apparatus comprising a housing (8) forming a working chamber (9), a dehumidifier (18), and an air supply means, wherein the metal housing (8) is provided with a laterally elongated operating hole (30), a plurality of strip flexible sealing members are arranged close to each other and suspended in the operating hole (30), a laterally elongated window hole (31) is disposed close to and above the operating hole (30) and closed with a light-transmitting window plate. The dehumidifier (18) circulates the air in the working chamber (9) by sucking the air therefrom, cooling the sucked air by an evaporator (48) of a compression refrigerator (41), dehumidifying the cooled air by a dehumidifying agent-carrying dehumidifying rotor (61), and returning the low-humidity air from the dehumidifying rotor (61) to the working chamber (9). The air supply means supplies outside air to the dehumidifying rotor (61) via an evaporator (58) to maintain the positive air pressure in the working chamber (9) and prevent the outside air supplied through the operating hole (30) from being mixed in the air in the working chamber (9). Thus the operation is conducted at a high efficiency by inserting the hands from the operating hole (30) into the working chamber (9) the interior of which is maintained at a low humidity.

摘要:
An improved method and apparatus for indirect evaporative cooling of a fluid stream to substantially its dew point temperature. Plate heat exchanger has perforations (11) and channels (3, 4 and 5) for gas on a dry side and wet side. There is a trough formed in a portion of the plate that temporarily holds evaporative fluid which is in contact with the wick material on the wet side surface of the plate. The evaporative fluid flows through the trough by way of liquid perforations into the next trough. The trough of a plate with a wet side up, the liquid perforations are on the side creating a reservoir to wet the opposing wick materials. As streams flow across the dry side (9), transferring heat to the plate. Working gas stream (2) flows across the dry side and through perforations to channels (5) on wet side (10), which it then cools by evaporative cooling as well as conductive and radiative transfer of heat from plate.
