HVAC design in Harat Al Sham

The decision depends on the building area, number of spaces and how it is used. In large commercial and hotel buildings a chiller gives flexible control and simplifies central maintenance. In apartments and smaller villas a split or ducted system usually fits better. The calculated heat load is what determines the right choice for your building.

Large glazing exposed to Jeddah's sun raises the heat load noticeably, especially on west and north-west facades. We calculate solar gain through each facade separately, and this can change the unit type selected for that room or require extra diffusers to handle the higher load.

Yes. When no drawings exist we visit the site and measure every space ourselves, recording facades, glazing and how each room is used. The survey takes longer than reviewing ready drawings, but the calculations still rest on real measurements rather than estimates, which is what makes the results reliable.

The drawings specify diffuser types, positions and sizes to match ceiling height and room shape, and show where dampers are needed to balance airflow to each zone. These details matter because a diffuser in the wrong place wastes a large part of the system capacity even when the units are correctly sized.

Yes. The top floor typically carries a higher heat load because the roof is directly exposed to the sun, which affects duct sizes and the number of diffusers needed on that level. We design each floor separately based on its own calculated load and show where dampers are needed to balance airflow between floors.

It depends on exact shop area, occupancy, windows and interior depth. We visit and measure heat load even for very small spaces, as wrong sizing wastes electricity or leaves the shop too warm.

Outdoor units are mounted on narrow facades, small projections or sometimes inside the shop itself in a ventilated space. We visit and assess available options and choose the best location based on actual building reality.

Weak wiring is common in Harat Al Sham. We inspect electrical lines on the visit and recommend a dedicated circuit for the AC if needed, or select a lower-consumption unit.

Trapped heat and high humidity significantly increase thermal load. We select a unit with slightly higher capacity than standard and ensure proper condensate drainage to prevent mould. All factored into design.
