Abstract:
A dehumidifying system supplies a gas free of organic substances. The dehumidifying system includes a holding case, and a rotor rotatably held in the holding case and bearing an adsorbent. The interior of the holding case is divided into an adsorbing zone and a regenerating zone by partition plates attached to the holding case. A process gas is supplied into the adsorbing zone. The process gas processed in the adsorbing zone is supplied into an objective space. A regenerating gas is supplied into the regenerating zone to eliminate moisture and organic substances adsorbed by the adsorbent in the adsorbing zone from the adsorbent.
Abstract:
A humidity controller apparatus (20) contains an adsorption rotor (24) and a heater (25). A first passage (21) along which a first air stream flows and a second passage (22) along which a second air stream flows are formed in the humidity controller apparatus (20). The amount of heat exchange between the first and second air streams and the amount of moisture exchange between the first and second air streams vary by adjustment to the rotating speed of the adsorption rotor (24), and the humidity controller apparatus (20) is switched between a dehumidification operation and a humidification/heating operation. During the dehumidification operation, the rotating speed of the adsorption rotor (24) is set low. The first air stream is dehumidified by the adsorption rotor (24) and then supplied to the inside of a room. The second air stream is used for regeneration of the adsorption rotor (24) and then discharged to the outside of the room. During the humidification/heating operation, the rotating speed of the adsorption rotor (24) is set high. The first air stream receives heat and moisture from the adsorption rotor (24) and then is supplied to the inside of the room. The second air stream is heat/moisture-adsorbed by the adsorption rotor (24) and then discharged to the outside of the room.

The filter assembly also includes a noise suppression element that reduces sound waves or noise emanating from any equipment, such as a compressor. The filter assembly can include a particulate filter portion for removing physical or particulate contaminants, a chemical filter portion for removing chemical contaminants, or can have both portions.
Abstract:
There is disclosed a method of manufacturing a ceramic honeycomb structure, which is capable of controlling a length of slurry pressed into each cell of the honeycomb structure when predetermined cells are plugged at an end surface of the honeycomb structure. A film 4 is attached to an end surface of the honeycomb structure 1. Holes 3a, 3b through the film 4 are made at a position corresponding to openings of predetermined cells 2a, 2b. The end surface is immersed into slurry 6 stored in a container 5 and the end surface is pressed so that the slurry 6 is pressed into the openings of the predetermined cells 2a, 2b. When the holes are made, two or more types of holes 3a, 3b having different diameters are made.
Abstract:
Disclosed is a heating element which can also absorb gas, especially a heating element usable as an interior material for buildings which serves both as a heater and an absorber capable of absorbing harmful gas present in the room. This heating element comprises: a molded product comprising a high-temperature carbonized charcoal which has been carbonized at a temperature of about 800° C. or above; and at least two electrodes which can energize the molded product, wherein current is applied to the electrodes to generate heat. The molded product comprising a high-temperature carbonized charcoal, which has been carbonized at a temperature of about 800° C. or above is excellent as a heating element and, at the same time, has an excellent capacity capable of adsorbing various gases. Mixing a low-temperature carbonized charcoal, which has been carbonized at a temperature of about 500° C. or below into the molded product and, further, a combination of the molded product with alginic acid or calcium oxide can provide a heating element having excellent absorption activity.
Abstract:
High density adsorbent structures may be constructed in parallel passage contactor configurations using improved high density adsorbent sheets. Improved high density adsorbent sheets may be formed using adsorptively active support or substrate materials upon which adsorbent material is applied, such as by coating processes, so that in the resulting high density adsorbent structure both the substrate and the coated adsorbent material are active in adsorption processes. Alternatively, improved high density adsorbent sheets may be formed comprising precursor materials, such as certain clays, which may be coated onto known support materials and thereafter converted to active adsorbent materials using known conversion techniques. This produces high-density adsorbent sheets comprising adsorbent material without inert binder material fractions. Improved self-supporting adsorbent sheets also may be formed without using support material, resulting in higher adsorbent densities relative to known adsorbent sheets.
