How to Measure Factory Cooling Energy Savings
Published by QIANGSHENG · Jingdong Smart Electric Co., Ltd.
Measure cooling electricity before and after a change, using comparable operating conditions and the same equipment boundary. Adjust for changes in weather, production and operating hours before attributing the difference to the new system.
Record a usable baseline
Collect cooling-system meter readings, shift hours, production activity and indoor conditions over a representative period. State whether the readings include pumps, fans and auxiliary equipment. A whole-factory electricity bill can conceal changes unrelated to cooling.
For a candidate floor-standing unit, record the rated input and model details from the Column Air Conditioner specifications, then use measured system consumption to evaluate actual savings.
Compare like-for-like service
Track whether the new installation maintains the same temperature, humidity and occupied area. Lower electricity use while delivering less cooling is not evidence of improved efficiency.
Report the calculation transparently
Energy reduction (%) = (baseline kWh − comparison kWh) ÷ baseline kWh × 100. Use a positive, comparable baseline and document any adjustments. Report water and maintenance changes separately when translating the energy result into operating-cost savings.
