How to Calculate Industrial Air Conditioner Payback
Published by QIANGSHENG · Jingdong Smart Electric Co., Ltd.
Simple payback in years equals the relevant investment divided by positive annual net operating savings. Use total installed cost for a retrofit evaluation, or the incremental cost when comparing two purchase options.
Include the complete installation cost
List equipment, freight, applicable import costs, electrical work, piping, installation and commissioning. Use the same scope for each proposal and identify costs that are already committed.
For a floor-standing proposal, identify the model from the Column Air Conditioner range and request its complete installed cost before calculating payback.
Calculate annual net savings
Start with the difference in annual electricity cost, then account for changes in water, maintenance and other recurring costs. Use the applicable local tariff and expected operating schedule. Rated input power alone does not establish annual consumption.
Illustrative example, not a customer result
If an installation costs US$20,000 and reduces net operating costs by US$5,000 per year, simple payback is 20,000 ÷ 5,000 = 4 years. These figures are hypothetical and are not a QIANGSHENG performance claim. If net savings are zero or negative, there is no positive simple payback.
Check sensitivity before buying
Recalculate with lower operating hours and smaller energy savings. Simple payback does not include financing, discounting or residual value. Ask for a project-specific comparison using your actual costs.
