Analysis and Calculation of Heating Load for a Residential Building.

The accuracy of heat load calculation directly affects the effectiveness of the heating system. The design specifications for Heating, Ventilation, and Air Conditioning (HVAC) building load calculations utilized the Tianzheng HVAC software (THS) load calculations and HDY-SMAD software (HSS). A 14-story residential building in Qingdao was taken as an example. The calculation of the heat load was biased and the results were compared with those calculated by the THS and HSS. The results showed that the winter load calculated was 251.3 kW by using HSS. The heat index per unit area in winter was 49.9 W/m2. The heat index per unit area was 32.6 W/m2 in summer.
