The total area (m 2) of ceiling, floor, external walls, external glazing (windows and doors) and internal walls (separating walls/doors) to other rooms or areas that are not included in the air conditioned room.The dimensions of the room to be air conditioned: length (m), width (m), height (m).The region (climate area) that the room is located in.To use the FairAir Cooling Load estimator you will need to know: Simplifications for residential applications include ignoring load diversity and simplifying calculation of latent cooling loads. Ventilation air load – Heat gain from minimum outdoor ventilation air provided in occupied spaces.Īll of these separate loads are then added together to get the full cooling load on the air conditioner for that room.Infiltration air load – Heat gain from air infiltrating from outside and adjoining spaces through doors and other openings.Internal loads – Heat gains from lights, appliances, equipment, activities and people.Solar load – Sensible heat gain through transparent building fabric elements (windows, doors).Transmission load – Sensible heat gain through walls, floors and ceiling.A room air conditioning load is made up of heat flowing into the room through the following components:
