摘要:
Echangeur thermique rotatif (10) permettant de récupérer la chaleur ou la fraîcheur et/ou l'humidité provenant d'écoulements de gaz. L'échangeur thermique comprend un logement (12) refermant des conduits (16, 18) d'écoulement de gaz. Le rotor d'échange thermique (22) fait partie d'une unité de rotor amovible (55) comprenant également un cadre (28) sur lequel le rotor est tourillonné, une paroi transversale (56) ayant un orifice destiné à loger le rotor, un moteur (40) d'entraînement du rotor, et une plaque de couverture (38) destinée à couvrir un orifice (36) situé dans le logement (12) à travers lequel l'unité de rotor peut être retirée. Disposé entre la paroi transversale (56) et la surface périphérique (62) du rotor (22) se trouve un joint périphérique (60) orienté radialement, auquel sont connectés, à l'intérieur de la zone du cadre (28), un joint axial (82) et un joint diamétralement opposé (48) respectivement.
摘要:
In dehumidifying systems which produce a controlled humidity environment in an enclosed volume using a circular desiccant bed system, a problem encountered is that sections of the desiccant bed cannot be absolutely isolated with respect to a section in process use and a section subjected to heated reactivating air flow. A co-mingling of process air and heated reactivating air may occur due to sealing problems and imbalances between the two air streams. The invention utilizes a carousel ring (2) mounted in a box frame (1), with a plurality of axial modular desiccant beds (2a through 2g) which are separated from each other by angular dividers (11a through 11e). A sector divider (53, 54) is provided within the carousel to separate process air flow (98) and regeneration air flow (96) and to provide isolated process and regeneration chambers for air flow through groups of individual beds. The modular beds are cyclically shifted by an indexed linear actuator (6) in a process-reactivating-process cycle as the carousel ring rotates about central axle (4).

An air conditioning apparatus (100) comprises an inlet module (1), an airflow guiding module (2) a hygroscopic wheel (3) a dehumidification heating module (4) and an internal recirculation heating module (5). The airflow guiding module (2) includes an air channel switching unit (21), an outflowing air channel (22) in air communication with an external environment outside of an air-conditioning environment, and an inflowing air channel (23) in air communication with the air-conditioning environment. The air conditioning apparatus of the present invention meets various requirements for air conditioning. In addition, when the air conditioning apparatus performs a dehumidification process, the hygroscopic wheel (3) and the dehumidification heating module (4) is applied to remove the moisture of the air conditioning flow of the inflowing air channel (23), and thus the relative humidity of the air-conditioning environment is directly reduced so as to increase the dehumidifying efficiency.

Control systems for recovery wheels, ventilation systems with recovery devices, buildings having ventilation, and methods of controlling recovery wheels and controlling or modifying ventilation systems. A parameter of ventilation systems or recovery devices, such as the speed of a recovery wheel, may be controlled as a function of pressure, differential pressure, flow rate, or fan speed, for example, to provide appropriate purge flow to maintain purge effectiveness and limit the carry-over of contaminants from a return/exhaust airstream to an outside/supply airstream, for instance, in a variable air-volume system. A purge angle may be set at a minimum position commensurate with a maximum flow rate and recovery-wheel speed may be reduced at lower flows to maintain purge effectiveness. In some embodiments, temperature and humidity are measured, and wheel speed is also controlled as a function of these measurements. Systems may utilize sensors, input devices, digital controllers, variable-speed drives, and alarms.

摘要:
A method by which water may be extracted from the air even without a supply of electricity from a power source or even without a supply of fuel, as well as an apparatus therefor, is disclosed. The apparatus used for the method for extracting water from the air comprises at least a rotatably mounted hygroscopic moisture-absorbing rotor having at least one region through which air can pass in the direction of thickness thereof; a passage for regeneration through which air for regeneration is circulated, of which both ends are opened at the opposing two surfaces of a regeneration region, respectively, the regeneration region being a part of the moisture-absorbing rotor, at which the moisture-absorbing rotor that absorbed moisture is regenerated; and a drain hole for taking out condensed water from the passage for regeneration.
