Water-Cooled vs Air-Cooled AC: What Should a Factory Compare?
Published by QIANGSHENG · Jingdong Smart Electric Co., Ltd.
Water-cooled and air-cooled systems differ in how they reject heat. Neither is the best choice for every factory. Compare the complete equipment package, site utilities and performance at the same design conditions.
Heat rejection and installation scope
Ask each supplier to identify the heat rejection equipment and every required connection. An air-cooled proposal should show outdoor airflow and clearances. A water-cooled proposal should identify the water circuit and any separate heat rejection equipment.
Water use and maintenance
If the water-cooled design includes a cooling tower, allow for make-up water, blowdown and water treatment. These requirements belong in the comparison alongside equipment purchase and electricity consumption.
A useful comparison request
Give both suppliers the same load, indoor targets, operating schedule and project location. Request total installed cost, full system electrical input, expected water use and maintenance scope. Ask them to state exclusions so that an incomplete quotation does not appear artificially cheaper.
If a floor-standing unit is under consideration, use the Column Air Conditioner model tables to prepare your comparison, then confirm the complete installation scope with the supplier.
