What does the Room Area Air Conditioning calculator do?

It estimates the cooling load of a room and recommends suitable air conditioner capacity in kW and BTU/h based on heat gains from walls, windows, people, equipment, and ventilation.

Which calculation modes are available?

Two modes: Quick (fast approximate result) and Pro (detailed input for more accuracy, including windows, insulation, and ventilation).

What inputs are required?

Room area, ceiling height, indoor and outdoor temperatures, number of occupants, lighting, equipment load, and optionally window area, orientation, insulation, and air change rate.

How is the cooling load calculated?

The tool sums heat contributions from walls, windows, solar gain, lighting, equipment, occupants, and ventilation, then applies a safety margin to determine total load.

How is the recommended AC size shown?

Results include total cooling load in watts, recommended capacity in kilowatts, and the equivalent in BTU/h.

What are the limitations?

Assumes steady-state conditions, average material properties, and typical ventilation rates. For precise design, full HVAC modeling is required.
