Description

AREA

[0001] The present disclosure relates generally to a solar-powered window drying evaporator system for desert regions for room air cooling and dehumidification. GENERAL STATE OF THE ART

[0002] Conventional cooling technologies include evaporative coolers, desiccant-based dehumidification systems, and chilled water coils, each addressing specific aspects of temperature and humidity control. Evaporative coolers lower air temperature through evaporation but increase humidity, limiting their effectiveness in humid climates. Desiccant systems utilize hygroscopic materials but require external energy for regeneration. Chilled water coils enable simultaneous cooling and dehumidification but rely on energy-intensive refrigeration infrastructure. Solar energy has been integrated into cooling systems for power generation and desiccant regeneration, but existing solutions are typically complex, centralized, and unsuitable for compact or window-mounted applications. A need remains for an integrated, energy-efficient, and renewable cooling system. SUMMARY

[0003] The subject matter of the present invention is defined in the claims. BRIEF DESCRIPTION OF THE FIGURES Fig. Figure 1 illustrates a solar-powered window drying evaporator system for desert areas for room air cooling and dehumidification. DETAILED DESCRIPTION OF THE INVENTION

[0004] Existing cooling systems are unable to provide effective cooling and humidity control simultaneously in a compact, window-mounted configuration. Evaporative coolers increase humidity, chilled water coils require significant energy and infrastructure, and dehumidifying systems rely on external regenerators, limiting their suitability for small-scale, renewable energy-based applications.

[0005] The invention discloses a solar-powered window drying evaporator system for desert regions, configured to deliver cool, dehumidified air into interior spaces. The system comprises an evaporative cooling unit with vertical panels equipped with porous sleeves and a fan positioned to draw outside air through the moistened sleeves to initiate evaporative cooling. A water circulation module, including upper and lower trays and a pump, maintains continuous water circulation through the porous sleeves to ensure sustained cooling performance. A cold water cooling coil positioned downstream of the fan is configured to further lower the air temperature and condense moisture from humid air, thereby enhancing cooling performance.The cooled air is then passed through a desiccant wheel containing a silica gel matrix that absorbs excess moisture and releases air within a comfortable humidity range. A solar-powered air heating module regenerates the desiccant wheel by removing the absorbed moisture using hot air generated from solar radiation. A solar panel power module supplies electrical energy to the fan, pump, and desiccant wheel, enabling off-grid operation. This integrated configuration allows for evaporative cooling, condensation, desiccant dehumidification, and solar energy utilization in a single, window-mounted system suitable for residential and commercial buildings.

[0006] Fig.Figure 1 illustrates a solar-powered window dehumidifying evaporator system 100, adapted to deliver cool, dehumidified air into interior spaces. The system 100 comprises an evaporative refrigerator 102 with vertical panels equipped with porous sleeves and a fan positioned to draw outside air through the moistened sleeves. A water circulation module 104, connected to a processor, includes an upper and lower tray and a pump to circulate water through the porous sleeves, thus enabling continuous evaporative cooling. A chilled water coil 106 is located behind the fan to condense moisture from the humid air and further reduce the air temperature.The cooled air is directed into a desiccant wheel 108, which contains a silica gel matrix that absorbs excess moisture and releases air within the humidity range comfortable for humans. A solar air heating module 110, also connected to the processor, regenerates the desiccant wheel by removing the absorbed moisture, while a solar panel power module 112 supplies the fan, pump, and desiccant wheel with electrical energy, thus ensuring sustainable operation.
