Heater device for desiccant rotor dehumidifier

A heater device applied in a desiccant rotor dehumidifier for supplying regeneration hot air to the desiccant rotor comprises a metal case having an air inlet and an air outlet; heating elements supported by insulative material and mounted adjacent to the desiccant rotor; and an insulative plate installed in parallel to the heating elements and parting the heating elements with the air inlet. The insulative plate is formed with a plurality of via holes suitably distributed for the intake air coming from the air inlet passing through, being heated by the heating elements and evenly passing the desiccant rotor through the air outlet. The insulative plate also splits and bypasses a part of the intake air to cool down the desiccant rotor that has been heated and regenerated.

Desiccant refrigerant dehumidifier systems

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.

Air desiccant system and method for automotive climate control

A method and system for climate control uses a desiccant in an automobile. The desiccant removes humidity or moisture from air passing through the ventilation system. The desiccant is recharged or dried by application of a vacuum. The lower pressure generated by the vacuum reduces the temperature at which water evaporates or boils off of the desiccant material.

Method and apparatus for extracting water from air using a desiccant

The present invention provides a method and apparatus for extracting liquid water from moist air using minimal energy input. The method can be considered as four phases: (1) adsorbing water from air into a desiccant, (2) isolating the water-laden desiccant from the air source, (3) desorbing water as vapor from the desiccant into a chamber, and (4) isolating the desiccant from the chamber, and compressing the vapor in the chamber to form liquid condensate. The liquid condensate can be removed for use. Careful design of the dead volumes and pressure balances can minimize the energy required. The dried air can be exchanged for fresh moist air and the process repeated. An apparatus comprises a first chamber in fluid communication with a desiccant, and having ports to intake moist air and exhaust dried air. The apparatus also comprises a second chamber in fluid communication with the desiccant. The second chamber allows variable internal pressure, and has a port for removal of liquid condensate. Each chamber can be configured to be isolated or in communication with the desiccant. The first chamber can be configured to be isolated or in communication with a course of moist air. Various arrangements of valves, pistons, and chambers are described.
