This drawing is the air conditioning and ventilation design and construction drawing of a comprehensive gymnasium in Sichuan, with a total building area of 39416 ㎡, including 12360 ㎡ for garage, 9487 ㎡ for commerce, 12569 ㎡ for gymnasium and 5000 ㎡ for natatorium.
Design content: The project includes the ventilation and air conditioning system of underground garage, equipment room, shopping mall, ground commercial room, office room, equipment room, swimming pool, basketball court, smoke control and exhaust system of the whole building, and positive pressure air supply of staircase.
Air conditioning system: the total air conditioning area of the project is 18264.09m2. Total cooling load: 4601.71kw, cooling index: 251.90 w/㎡, thermal load: 2494.30kW. Thermal index: 136.57W/m2.
1. The building area of the gymnasium is 7000 ㎡, the design cooling load is estimated to be 1750kW, the cooling index is 250w/㎡, and the heating load is 1100kW. Thermal index: 157W/㎡. (The cold index of the office is 150w/㎡, and the heat index is 110w/㎡
2. The commercial building area is 9487 ㎡, the design cooling load is estimated to be 2100 kW, the cooling index is 221 w/㎡, and the heating load is 1400 kW. Thermal index: 147W/㎡.
3. The gymnasium uses a gas direct fired lithium bromide absorption cold and hot water unit, one ZX-233HZ, Q=2330KW, Q heat=1856KW, COP=1.36, variable frequency refrigeration pump KHB-150-315A, L=374m3/h,H=28M, Variable frequency cooling pump KHB-300-200, L=720m3/h,H=28M。 (One for standby and one for use)
4. Gas direct fired lithium bromide absorption cold and hot water unit is selected for commercial use, with one ZX-233HZ, Q=2330KW, Q heat=1856KW, COP=1.36, variable frequency refrigeration pump KHB-150-315A, L=374m3/h,H=28M, Variable frequency cooling pump KHB-300-200, L=720m3/h,H=28M。 (One for standby and one for use)
5. The natatorium uses a three in one machine, with a refrigerating capacity of 190kw, heating capacity of 229kw, residual pressure of 800pa (2 sets), and the winter heat source is supplied by the refrigerator in the gymnasium.
6. The gymnasium adopts cross flow cooling tower LRCM-HS-700, L=700m3/h, and the commercial uses cross flow cooling tower LRCM-HS-700, L=700m3/h
