For the Suzhou area, approximatelyA 1,500㎡ industrial factory building requires special attention to the installation of the central air conditioning system to ensure efficient operation, meet process requirements, and reduce long-term operational costs.
I. Preliminary Planning and Load Calculation
Cool Load Estimation:A 1,500㎡ factory with a height of 6-8 meters would have a cooling load of approximately 180-240 kW (120-160 W/㎡) based on industrial standards, which needs to be adjusted according to the heat generated by equipment, personnel density, and process temperature and humidity requirements.
For areas within the factory with varying temperature and humidity requirements (such as assembly areas, storage areas), it is recommended to use a multi-split system or a water system terminal with independent zoning control.
Section II: Aircraft Selection and Layout
Chassis Type: Prioritize air-cooled modular chillers or water-cooled screw chillers (if cooling water is available), with the former suitable for Suzhou's low-temperature operating conditions during winter.Above -5°C, it operates; the latter has higher energy efficiency.
Position Requirements:
Outdoor Unit: Keep away from heat sources (such as boiler rooms), avoid direct sunlight, and reserve≥1-meter maintenance space is required, with multiple units arranged horizontally to prevent heat recirculation.
Indoor Unit: Utilize side-air delivery method (air outlets positioned on the short side), with a throw distance to cover the entire area, avoiding dead zones; return air should be connected through ducts, and it is prohibited to use the ceiling space directly for return air.
Expansion tank: Located at the highest point of the system, it requires frost protection (due to the damp cold winter in Suzhou, it is recommended to add insulation).
III. Local Environment Adaptation in Suzhou
Humidity Control: Suzhou's Average Annual Humidity ReachesOver 75% require dehumidification features, such as rotary or refrigerant dehumidification, particularly suitable for precision manufacturing workshops.
Corrosion Protection: For factories near Taihu Lake or chemical zones, outdoor machines must be equipped with stainless steel casings or coated with anti-corrosion paint. After copper tube welding, nitrogen should be filled for protection against oxidation.
IV. Key Installation and Construction Points
Foundation Reinforcement: The main unit and pump must be installed on a concrete foundation (thickness)≥20cm, with the load-bearing design based on 1.5 times the operating weight of the equipment (including the ice storage system).
Vibration and Noise Reduction:
- Additional rubber shock absorbers (thickness ≥ 2cm) are installed between the main unit and the base, while the air duct hangers use spring shock absorbers.
- Strict environmental protection requirements are in place in certain areas of Suzhou (such as the Industrial Park area), with noise levels needing to be controlled at ≤65dB(A) during daytime.
Pipe Construction: Copper Pipe Welding Post24-hour pressure hold leak detection (pressure ≥ 4.0 MPa), condensate drain slope ≥ 1%, to prevent backflow of condensate during the Suzhou rainy season.
Proposed Solution (Example)
System Configuration:2台风冷模块 units (each with a cooling capacity of 130kW) + 8 jet units (each with a volume flow rate of 6000 m³/h) + a fresh air enthalpy heat exchanger.
Cost Estimation: Equipment+Installation costs approximately 250,000 to 300,000 yuan (inclusive of local labor premium in Suzhou).
