Many factory owners run into pitfalls when planning workshop cooling.
Choosing equipment by guesswork leads to insufficient cooling and sweltering workshops, or over‑sized units wasting massive electricity costs
Lengfengge, an expert in workshop cooling, shares the professional calculation method. Four key dimensions determine your required cooling capacity, easy for beginners to understand
Dimension 1: Workshop Area & Ceiling Height (Basic Cooling Load) This is the baseline for cooling‑capacity calculation, adjusted for air‑tightness and height: ✅ Well‑sealed, low‑ceiling workshop: 150W per square meter ✅ Poorly‑sealed, high‑ceiling or well‑ventilated workshop: 200‑250W per square meter
Dimension 2: Heat Dissipation from On‑site Staff (Human Heat Source) Heat output varies greatly according to labor intensity for accurate calculation: ✅ Light‑industry, sedentary or light‑duty work: 100‑150W per person ✅ Heavy‑duty work, handling and frequent movement: 150‑200W per person
Dimension 3: Heat Generation from Equipment (Most Critical Factor) The hidden major heat source in workshops. Wrong calculation renders air‑conditioners ineffective!
Machinery such as injection molding machines, film blowers and extruders generate massive heat during operation. Sum up the total kilowatt heat output of all heat‑producing equipment. This is vital for satisfactory cooling performance.
☀️ Dimension 4: Ambient Heat Balance (Easily Overlooked) Poor cooling results often stem from neglecting this factor!
Take into account rooftop sun exposure, west‑facing solar radiation, frequent opening of doors and windows, and constant personnel & equipment access. These factors disrupt constant‑temperature conditions and consume cooling capacity. This is also the most experience‑dependent and challenging calculation in the industry.
