根据《民用建筑供暖通风与空气调节设计规范》（GB50736-2012）

According to 7.2.7 on page 48 of the "Code for Design of Heating, Ventilation and Air Conditioning of Civil Buildings" (GB50736-2012), the cooling load of the building air conditioner is calculated according to the non-steady-state method. It is mainly formed by the hourly cooling load formed by the unsteady heat transfer introduced through the enclosure structure, the hourly cooling load formed by the heat of solar radiation entering through the glass window, and the heat dissipation of the human body, lighting and equipment Hourly cooling load and other loads. The cold load is calculated according to the non-steady state method, and the cooling load is as follows

According to the Design Specification for Heating Ventilation and Air Conditioning in Civil Buildings (GB50736-2012) page 7.2.7, the cold load of building air conditioning is calculated according to the non-steady state method of each time-by-time cold load. Mainly by the protective structure of the introduction of non-steady-state heat transfer formed by the time-by-time cold load, through the glass window of the sun radiation heat formation of the time-by-time cold load, the human body, lighting and equipment and other aspects of cooling formation of time-by-time cold load composition. The cold load is calculated according to the non-steady state method, the method is as follows

According to 7.2.7 on page 48 of code for design of heating ventilation and air conditioning of civil buildings (gb50736-2012), the cooling load of building air conditioning is calculated by the unsteady state method. It is mainly composed of hourly cooling load formed by unsteady heat transfer from enclosure, hourly cooling load formed by solar radiation through glass window, hourly cooling load formed by heat dissipation from human body, lighting and equipment. The cooling load is calculated according to the unsteady state method. The method is as follows
