What is the design heat load for a heating system? The design heat load of a heating system is the amount of heat supplied to a building per unit of time, at a certain outdoor temperature, in order to maintain thermal balance in the room and meet the desired indoor temperature. The design heat load Q′ for the heating system consists of two parts: one is the heat loss through the building’s envelope, Q1′, that is, the heat that escapes from the interior to the exterior through the building’s doors, windows, floors, roof, and other structural elements ； The other part consists of the cold air infiltration heat loss Q′, which is the heat required to warm the cold air that enters the room through gaps in doors and windows, and the cold air intrusion heat loss Q′, which is the heat required to warm the cold air that enters the room as a result of doors and windows being opened.
The amount of heat supplied by the heating system to a building per unit of time.
It refers to the heating load corresponding to the outdoor calculated temperature for heating. Based on the outdoor design temperature specified in the \"GB 50019-2015 Code for Design of Heating, Ventilation and Air Conditioning in Industrial Buildings,\" the heating system must supply a certain amount of heat to the building per unit of time in order to achieve the desired indoor temperature.
