The order of viewing the floor plan is: ground floor--floor--roof--basement--large drawing. It is necessary to understand the arrangement of air ducts and water pipes on each floor plan, the position and number of risers, the number and position of the plan and the size of water treatment equipment. air, position of air conditioning outlet accessories, air specifications. ducts and water pipes, etc., and understand the impact of HVAC planes on civil engineering Requirements for building construction and decoration, coordination of types of works, stastatistics of the number of devices, equipment and accessories in the aircraft and length of pipelines as a basis for the HVAC project budget and material procurement.
No. The fresh air machine room is mainly used for air supply, exhaust and air treatment, aiming to provide a clean and comfortable indoor environment.
