The designs included the system of a certain restrant’s center air-condition in NanChang. The whole air-contion section was plotted according to the different function-region, including: fan coils and the system of fresh air all-air system microtome-ceil air system The main-machine and fan coils’ choice were based on the calculation of cold-load. And through the numeration of blast voume and water flux, the standard of air duct and water pipe was determined. The most disadvantage resistance and pressure of the loop-road were checked up to ensure the machine of fresh-air and water pump. According to the parameter which was offerd by the correlate air-condition design handbook, the choice of fresh-air machine, water pump and the hot water machine was finished. Then the part of the sanitation-hot-water was performed. At last, the whole design was shown on the drawing.
