Ventilator Device For Dehumidification

Abstract

A ventilation device and the method of use thereof for dehumidification of residential attached or detached garages, sheds, greenhouses, RVs, motorhomes and other similar structures. This device and method uses an extraction ventilator to dry out the structure's environment, and reduce the interior humidity using a motorized fan to expel moisture latent air out of the structure. The fan continuously runs at minimal speeds to continuously exhaust interior air and ventilate the structure, thereby controlling the garage environment, while eliminating backdrafts, and preventing animals, snow and rain from entering the structure. The device uses a dehumidistat control to activate the fan to maximum ventilation capacity when the humidity reaches the set point, exhausting ambient air and extracting excess humidity from the structure. Once the humidity drops below the set point, the dehumidistat deactivates and returns the ventilator to minimum speed operator.

Description

TECHNICAL FIELD [0001] The present invention relates to a humidity control device and to controlled humidity transfer during ventilation of a structure. BACKGROUND OF THE INVENTION [0002] New and better construction methods and materials have resulted in more air tight construction, to the point where ventilation has become a necessity for humidity control in annex structures such as newer built or newly renovated garages, pool or garden structures or in similar structures. [0003] Furthermore, normal usage of these structures (garages, sheds, greenhouses, pool houses) enhances and naturally creates humidity issues. Introduction of wet and humid equipment to these structures is common (snowblowers in winter, cars anytime of the year, pool houses in general, sprinklers in greenhouses in hot days makes them to hot and humid for plants . . . ) creating excess humidity which can damage contents and the structure itself if not resolved. [0004] These structures are often open in the daytim...

AI Technical Summary

Benefits of technology

[0007] The present device uses a structure's natural air permeable characteristics in order to control its environment by eliminating excess humidity resulting from changes in environment from added moisture in the structure, such as parking a wet car in a garage structure or wet pool accessories in a pool shed.

[0008] The device is equally effective to regulate a structure's environment by eliminating possible condensation and preventing corrosion due to outside environmental changes such as rain, snow, cold mornings, hot humid afternoons and the like.

[0010] The interior air withdrawn from the structure is exhausted outside into the atmosphere, removing the stalest and dampest air. Normally external ambient air is drier (lower relative humidity) than moisture laden interior air. The present system forces air circulation of drier outside air into the structure while exhausing moist interior air, and thereby reduces humidity in the structure for humidity control. Nonetheless, even where there is high exterior humidity, continuous circulation of air in the structure is desirable to minimize condensation.

Problems solved by technology

Furthermore, normal usage of these structures (garages, sheds, greenhouses, pool houses) enhances and naturally creates humidity issues.

. . ) creating excess humidity which can damage contents and the structure itself if not resolved.

These structures are often open in the daytime for use and closed overnight, which lets in humidity in the daytime and traps it in overnight causing humidity and excess moisture or condensation issues.

Summertime movement or infiltration of air from outside can result in condensation, which can lead to mold formation and odors, as well as structural damage and rust formation on tools and equipment.

Current household ventilation systems do not address the issues of these auxiliary structures in view of the risk of air contamination into living areas.

De-humidifiers with condensate coils address localized indoor humidity problems, however they are very costly to operate and do not address indoor air quality.
