After obtaining the CAD drawings provided by the architectural professional, the HVAC professional engineers must first determine the cold and heat load of the building to carry out the design of the profession. The existing HVAC CAD software can almost calculate the building load, but Because the functions of each software are different in details, there is a big difference in the operation of human intervention. In the acquisition of the temperature difference between the rooms on both sides of the wall, Haochen HVAC software has obvious advantages.
Room search for architectural drawings
In order to realize automatic analysis and obtain the temperature difference between the rooms on both sides of the wall, first search the room for the architectural drawings, run the “Load Calculation-Automatic Arrangement†command, pop up the window below, and click “Select the floor plan for automatic numberingâ€. You can search all the rooms in the frame selection on the drawing and filter out the rooms that do not need to participate in the calculation.
Next, analyze the properties of the interior and exterior walls of the building map, and realize it through the function of “recognizing inside and outsideâ€. At this point, the preparation work for the room search is completed, and the "load calculation-tool-read building map" is run to import the building information in the drawing into the load calculation window. During the reading process, the "matching template to add load object data" needs to be selected. This will match the room in the drawing with the setting parameters of the room template manager, and complete the automatic setting of the room temperature and humidity and the room load object.
After reading the building information, we look at the "interior wall" of the room load object one by one. At this time, the software has recognized the heating conditions on both sides of the inner wall and automatically handles the inner wall load in two modes:
1. The rooms on both sides of the inner wall are heated. The software will calculate the internal wall load on the higher side of the room temperature, and calculate the internal wall load according to the heating design temperature difference between the two rooms. When the temperature difference between the two rooms is less than 5 °C, the software The load on the inner wall can be ignored as required by the specification;
2. The room on one side of the inner wall is warmed and the other side is not warmed. The software will calculate the internal wall load on the side of the heating room. By default, the load result is obtained by “temperature difference correction, correction factor 0.5, and room temperature is not equalâ€.
