The Sharp AY-XP18HR provides 18000 BTU cooling and reverse cycle heating capability combined with integrated Plasmacluster Ion purification for mid-to-large residential zones and light commercial interiors. Sharp's dynamic DC inverter motor ensures smooth, modulated operation, significantly curbing energy usage and maintaining narrow temperature bands. Active ionisation continuously purifies indoor air, actively targeting airborne microbes, volatile compounds, and lingering cooking aromas. The unit features multi-directional motorised louvres that distribute conditioned airflow evenly across wide open-plan floorplates and contemporary extensions. Incorporating an independent dehumidifier setting, the AY-XP18HR effectively extracts excess moisture during humid British summer days. With its anti-corrosive outdoor condenser casing, eco energy-saving setting, and robust low-ambient heating capability down to freezing winter temperatures, this system offers complete all-season climate dependability.
