Industrial air conditioning is one of the core infrastructure components in production workshops. A suitable industrial air conditioning unit not only significantly enhances employee comfort and productivity but also effectively ensures the stable operation of precision equipment. However, selecting the right industrial air conditioning is a complex engineering system, far from being a simple"Area Matching." Incorrect selection can lead to poor refrigeration performance, high energy consumption, frequent equipment failures, and even impact the entire production process.

Tianxiang Electromechanical will introduce the key considerations for selecting industrial air conditioning systems in factories, providing you with a practical selection guide.

One, select air conditioning units starting from the cooling load requirements.

Cooling load calculation is the cornerstone of the entire selection process, directly determining the cooling capacity required for the air conditioning. In industrial environments, heat sources are complex and professional calculations are essential; estimating based on experience is highly discouraged.

Key considerations for heat loads include:

Thermal Insulation of Enclosure Structures: Material, thickness, and thermal insulation of roofs, walls, and floors; area and type of doors and windows.

Heat dissipation from equipment: The heat generated by the operation of production equipment, machine tools, furnaces, etc., which is usually the main heat source within the factory building.

Staff Cooling: Number of permanent staff.

Lighting Heat Dissipation: Power of all lighting equipment.

新风 Load: The cooling burden introduced by introducing outdoor fresh air to maintain the车间 air freshness.

Professional Recommendation: Always entrust HVAC engineers to use professional software for detailed calculations to determine the total cooling load (unit:The company has reserved 10%-20% surplus capacity (kW) to accommodate future production increases or process upgrades.

Choose the appropriate type of air conditioning system

Selecting the most suitable system type is a critical step, based on the factory's size, structure, usage characteristics, and budget.

1. Split-type Air Conditioner，SuitableSmall workshop, office, partial cooling, low initial investment, easy installation, but lower energy efficiency, multiple outdoor units.

2. Multi-connection System，No Chinese content provided.Medium-sized workshop, areas requiring independent zoning control, flexible control, high energy efficiency, high installation requirements, and limited pipe length.

3. Air-cooled pipeline central air conditioning，No Chinese content provided.Medium-sized factory, overall cooling, space with ceiling.Uniform air distribution, compatible with fresh air integration, requires ceiling space occupancy.

4. Water-Cooled Chiller Unit，No Chinese content provided.Large-scale factory, long operational hours, high energy efficiency, extremely high energy efficiency ratio, low operation costs, requires cooling towers and machine rooms.

5. Air-cooled screw unit，AppropriateLarge factory, water-scarce areas: No cooling towers required, water-saving but slightly lower energy efficiency than water-cooled systems.

6. Evaporative Cooling Air Conditioners，Not providedHigh-temperature, low-humidity workshop with minimal humidity requirementsExtremely energy-efficient and providing fresh air, but its cooling capacity is significantly affected by humidity.

7. Rooftop Air Conditioner Units，No Chinese content provided.Large single-story factory and warehouse, with no indoor space occupied, requiring reinforced roof load-bearing capacity.

Selection Suggestion: For large industrial factories, water-cooled chillersA combination of modular air handling units and fan coil units is typically the most energy-efficient and economically viable solution in the long term.

Section III: Factory Air Conditioning Performance and Function Considerations

Once the system type is confirmed, it's essential to delve deeper into the following performance indicators:

1. Efficiency Metrics: Focus on the IPLV (Integrated Part Load Performance Ratio). Factory air conditioners are not typically operating at full load most of the time, making the IPLV value a more accurate reflection of their energy-saving levels in daily operation than the nominal EER/COP values.

2. Reliability and Stability: Industrial air conditioning systems must withstand rigorous 7x24 continuous operation tests. Choosing a well-established, mature brand and a quality-reliable industrial compressor (such as scroll or screw type) is crucial.

Adaptability to the Environment

Protection LevelFor dusty workshops, select equipment with IP54 or higher ratings to prevent dust from entering.

Explosion-proof Certification: Workshops in the oil, chemical, and spray painting industries, where flammable and explosive risks are present, must use explosion-proof air conditioners.

Corrosion-Resistant Technology: In environments prone to corrosion, such as electroplating, chemical processing, or coastal areas, it is essential to select products that have been specially treated for corrosion resistance.

4. Air Distribution Method: Factory buildings are typically high in ceiling, so it's advisable to avoid direct cold air flow. We recommend using spherical nozzles, swirl diffusers, and other long-distance air distribution methods to allow cold air to naturally descend, creating a uniform and comfortable airflow pattern, thereby avoiding energy waste.

5. Smart Control: Modern industrial air conditioning systems should support centralized control, variable frequency regulation, and remote monitoring for easy implementation of refined energy management and preventive maintenance.

Four: Other Non-Negligible Factors

Total Investment Budget: Weighing the initial equipment investment against the long-term operational costs such as electricity and maintenance fees. High-efficiency equipment may have a higher purchase cost, but could offer a better long-term return.

Electricity Capacity: Large air conditioning systems consume a significant amount of power, so it's essential to confirm in advance whether the factory transformer has enough capacity to support it.

Proper Planning: Pre-arrange equipment installation locations (roof, ground), space, and ductwork/Installation route for water pipes. Also consider ease of daily cleaning and maintenance, as well as the availability of spare parts.

Industrial air conditioning selection is a rigorous technical decision-making process. We strongly recommend contacting a professional HVAC service provider or design unit. Suzhou Tianxiang Electrical and Mechanical offers customized solutions.
