1results about How to "Guaranteed regeneration effect" patented technology

This invention discloses a PTC regeneration bypass control method for window-type oxygen-enriched membrane fresh air systems, belonging to the field of air handling equipment control technology. The method includes: real-time monitoring of the oxygen-enriched membrane component performance degradation rate, dew point of the drying unit, indoor carbon dioxide concentration, and indoor-outdoor temperature difference; comprehensively determining the oxygen-enriched membrane performance degradation and the drying unit regeneration needs, and calculating and selecting the optimal time point with the least impact on the indoor environment to initiate regeneration, taking into account indoor air quality and heat load conditions; first switching to bypass ventilation mode to maintain basic air exchange, while simultaneously regenerating the drying unit and independently expelling moisture outdoors; and smoothly switching back to the original operating mode after regeneration is complete. This method solves the problems of improper regeneration timing, impact on indoor ventilation and comfort during regeneration, and high regeneration energy consumption in existing technologies, achieving efficient, energy-saving, and intelligent regeneration and maintenance of core consumables while ensuring continuous indoor air quality.
