1. Case : Precision Temperature Control Project for ElectronicManufacturing Workshop, Bac Ninh Province
2. Project Background
Bac Ninh Province is a key electronic manufacturing hub in Vietnam, where outdoor summertemperatures often hit 35-38°C. This workshop specializes in precision electronic componentassembly, demanding stable indoor environment (temperature fluctuation s1°C, relative humidity55%-65%). Vietnam faces periodic power shortages, and traditional central air conditioning systemsare too energy-intensive and costly for the enterprise, hindering stable production.
3.Technical Solution
Adopt a combined indirect and direct evaporative cooling system: Equip 4 indirect evaporativecooling units to pre-cool outdoor air and remove excess moisture, 12 direct evaporative air coolers forfurther temperature reduction, and an intelligent PLC control system for automatic regulation basedon real-time environmental data.
4.Implementation Effects
Environmental Performance: Indoor temperature maintained at 26-28°C, relative humidity58%-62%, fully complying with precision manufacturing requirements; high-temperatureequipment failure rate reduced from 12% to less than 2%.
Cost Efficiency: 55%-60% less energy consumption than traditional central air conditioning, annuselectricity savings of approximately 420,000 RMB, with an investment payback period of only 8months.
Productivity Improvement: Labor productivity up by 22%, product defect rate down by 1.5%.
