中央空调系统设计及气流组织形式优化

Design of central air conditioning system and optimization of airdistribution formAbstractThe design is the hospital inpatient complex building,located in Maoming City,Guangdong Province.According to the requirements,the central air conditioning system isdesigned to design a safe and healthy indoor environment for indoor medical staff and patients.The total construction area is about 26428 m',the area on the ground is 22313 m',the totalair conditioning area is 13972.55 m',there are 15 floors on the ground,the building height is57.6 meters,and the functions include inpatient,outpatient,office and ward.In the air conditioning design,the water machine system is mainly used for the first floorto the fifteenth floor above the ground,and the end cooling capacity is about 1546.2kw.Interms of energy saving,three 830kw screw machines are used,and the same opening rate ofthe main engine is 93.14%.The design description includes:calculating the room cooling load of the system throughTianzheng;analyzing the differences of various air-conditioning systems and selecting themost suitable scheme;selecting and checking the air-conditioning terminal unit;designing andarranging the fresh air system;simulating the air supply and return modes in the room throughsoftware,and analyzing the air distribution;arranging,designing and hydraulic checking thechilled water pipeline;air pipe and water Heat preservation of pipe;treatment of noisereduction and vibration reduction.Keywords:Hospital;central air conditioning;airflow simulation.
