[Fujian] Archives Ventilation and Air Conditioning engineering construction programme
A new archives in Fujian Province is a high-rise building with one floor underground and eight floors above the ground. The cornice height is 39.2M. The total building area is 40810m2, and the basement is mainly the parking garage and equipment room. The design scope of this project includes: the design of central air conditioning system and corresponding ventilation and smoke control system for single buildings above the ground, the design of central dust collection system for archives warehouse, the design of ventilation and smoke control for underground garage and equipment room, and the design of ventilation for underground civil air defense material warehouse. All elevator machine rooms are reserved with split air conditioning sockets by the electrical discipline. Installation requirements of air conditioning water system: 1. The pipes shall be cut by mechanical method. When the pipe diameter is large or cannot be cut by mechanical method, the oxyacetylene flame shall be used for cutting. The cutting section shall be perpendicular to the pipe centerline, and the internal and external diameters of the pipes on the section shall not change; Pipe groove shall be machined. The cut section and groove surface of the pipe shall be free of cracks, burrs, etc. after processing, and shall be processed to a smooth surface. 2. Before installation, the completed piping section shall be carefully checked with the construction drawing to confirm the connection part with the unit, and consider the installation of equipment, then confirm the construction scheme, and prepare the equipment and materials for installation. Confirm whether the construction environment meets the requirements. 3. Before the installation of pipes and pipe fittings, the rust and dirt on the inner and outer walls shall be cleaned, and then the compressed air shall be used to blow them clean. When the inner and outer walls of the pipes are clean, the pipe orifices at both ends shall be sealed for installation to keep the inner and outer walls dry. Before installation, all valves shall be subject to assembly performance inspection to check whether their actions are correct and flexible...... 4. Pipeline welding shall be carried out according to Code for Construction and Acceptance of Field Equipment and Industrial Pipeline Welding Engineering (GBJ236-82). For the welding of pipes with different diameters, if the difference between the diameters of the two pipes is not more than 15% of the small pipe diameter, reduce the diameter of the end of the large pipe and weld it with the small pipe...... 5. The connecting pipe between the water pipe and the fan coil shall be straight, and no leakage is allowed. The slope of the air condensate pipe connected to the fan coil unit is 1%, and the air condensate pipe of the air conditioner must be equipped with a water seal. The slope of the pipe is 1%, and no reverse slope is allowed...... 14. After the installation of the pipe and before the commissioning of the system, the pipe shall be marked. Pipeline signs shall be marked layer by layer according to water supply and return of freezing pipe, water inlet and outlet of cooling pipe, so as to facilitate the management and maintenance of the system. 15. Before the system is officially put into operation, the chilled water and cooling water must be treated with medicated water, and preservatives, scale inhibitors and bactericides must be added.
