How this estimate works

Assumptions, in the open.

It is a budgetary figure (roughly ±20%) based on typical cooling densities for Saudi buildings, a climate factor for your city, and current installed market rates per ton of refrigeration. A site survey and detailed load calculation always follow before any offer.

Variable Refrigerant Flow — one outdoor system serving many indoor units, modulating capacity to each zone's demand. It offers individual room control and strong part-load efficiency compared with conventional DX systems.

Design ambient temperature (Riyadh ~46–48°C), glazing and orientation, insulation, ceiling height, occupancy and internal loads, and run hours. The calculator captures the main factors; our engineers refine the rest on site.

Yes — for factories, halls, showrooms and kitchens, Oxycom’s IDEC (Indirect Direct Evaporative Cooling) is often the lowest-cost option. Tick “commercial kitchen” or ask us in the form.

Disclaimer — indicative figures only. This calculator provides indicative estimates for initial guidance. It uses simplified climate profiles and typical assumptions; actual performance, savings, capacities and equipment selection depend on a site survey and a project-specific engineering study. The results do not constitute an offer, a quotation, a performance guarantee or a commitment of any kind by Dosan Energy, and may not be relied upon for contractual or design purposes.
