2、 Design scope: 1. Swimming pool circulating water treatment equipment system; 2. Swimming pool water heating constant temperature system; 3. Indoor air treatment (constant temperature and humidity) system of swimming pool. 3、 System design: 1. The swimming pool and swimming pool use the same set of equipment, with a total water volume of about 476 m3, a cycle period of 6 h, and a circulation flow of 83.3 m3/h; The additional coefficient is 1.05; 2. Pool water circulation mode: mixed flow (counter flow) type, taking 30-40% of the circulation flow from the bottom of the pool and 60-70% of the circulation flow from the pool surface for circulation, and evenly distributing water from the pool bottom, so as to facilitate the effective circulation of the water body and the uniform mixing of cold and hot water. When the return pipe at the bottom of the pool is closed, the system is counter flow circulation; 3. Water temperature of swimming pool: design water temperature 28 ℃; 4. Pool water heating mode: the ground source heat pump heat source (provided by Party A) and the hybrid air source heat pump are combined to heat and stabilize the swimming pool. In daily use, the heat recovered from the air dehumidification of the hybrid air source heat pump is used to stabilize the swimming pool water body, and the ground source heat pump is used to supplement the heat when it is insufficient; 5. Circulating filtration equipment: based on the requirements of the new water quality standard, the design selects the plate and frame diatomite filter unit with high filtration accuracy and currently more advanced to ensure the quality of effluent. 6. Pool water disinfection method: ozone assisted chlorine disinfection method. 4、 Electrical configuration description: 1. Initial heating time of swimming pool: ≤ 48h; 2. Configuration power of heat source required for initial heating: ≥ 254.4Kw; 3. Equipment configuration: diatomite filter unit power: 5.5Kw, mixed air source heat pump: 38.64 Kw; The hybrid air source heat pump is normally open during daily operation, and can provide water heating output power of 87.6Kw to meet the needs of air heating, dehumidification and heat recovery for constant temperature of water body; 4. The total distribution power of all equipment is about 55Kw. 5、 Air constant temperature and humidity system: 1. Designed air exchange rate of natatorium: ≥ 3 times/h, air exchange rate of equipment: 22000m3/h; 2. Design wind speed of supply and return air ducts: ≤ 6.5m/s, sectional area of main air duct: ≥ 1.0m2; 3. Dehumidification capacity of swimming pool space: ≥ 80L/h; 4. Design air temperature of natatorium: ＞ water temperature of swimming pool 1-2 ℃. 6、 Others: 1. UPVC pipes with pressure rating of 1.0MPa are selected for the circulating system of the swimming pool; 2. PPR hot water pipes are selected for shower heating system, solar heating system and forced shower system, and the pressure rating is 1.6MPa; 3. Accessories not specified or noted (swimming lane line, pool lamp, overflow port, water supply port, sewage suction port, escalator, etc.) shall be constructed with reference to atlas 04S107.
