AIRAH recommends a full load calculation be completed by an air conditioning contractor or designer.

The FairAir Cooling Load estimator is an estimate only, based on a series of assumed default values and a series of user inputs. Small Window Air Conditioners efficiently save. Window AC units are relatively smaller than Split ACs, thereby saving up on that ever important square footage. It is good, easy-to-install option for those who find Split AC expensive. The number of occupants in the room and the type of room usage, either living room or bedroom.īased on the user input and the in-built default assumptions, the FairAir Cooling Load estimator will provide an estimate of the cooling load for that room.įind out more about Reducing the Cooling Load of a Room.įind out more about Energy Efficiency, Installation and Maintenance. A Window Air Conditioner, also referred as Window AC or room air conditioner, is designed to cool a single room.

The type of any glazed windows and doors, and the orientation of the glazed areas (the compass direction they face), and the extent of any shading that applies to the glass, such as permanent overhangs and awnings or internal blinds and curtains.

The type of construction of the main building elements: roof/ceiling, floor, internal and external walls, including whether they have been insulated or not.

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).

Even the least-expensive units we researched for our review of the best window air conditioners got a score of 11, and all of our picks were rated 12 or 12.1. A big 14,000 BTU air conditioner should only use 1,250 watts. A mid-size 8,000 BTU AC should use fewer than 715 watts.

Transmission load – Sensible heat gain through walls, floors and ceiling For a small bedroom, a 5,000 BTU window unit should only use 450 watts.

A room air conditioning load is made up of heat flowing into the room through the following components:
