The design temperature for cooling load is the temperature at which the cooling system must be able to operate in order to meet the cooling needs of the building. This temperature is determined by the climate of the area, the type of building, and the desired indoor temperature. Generally, the design temperature for cooling load is set at the highest temperature that the building is expected to experience during the hottest months of the year. This temperature is usually between 75-95°F, depending on the climate and the building’s insulation.
