Upon completion of the program is determined, the wind and water systems for the resistance calculation, in the calculation process, the comprehensive economic factors, and other factors that determine the quality of pipe, duct hose pipe to determine the path, the path of resistance is the most unfavorable results, combined with the cold load, such as selecting the appropriate air volume air conditioning end products as well as auxiliary equipment. In the design process, find a variety of manufacturers product samples, understand today the manufacturing level, and follow the HVAC design relevant standards and regulations, to discuss the design problems encountered and lessons learned. According to the design process and the calculation results using CAD drawing standard floor air conditioning system plan, water system diagram, the wind system diagram, isometric drawings.
