Many factory owners report that their evaporative‑cooling energy‑saving air conditioners deliver far weaker cooling after more than a year of operation.
Poor cooling does not always mean the unit is broken. Check these points one by one first
Clogged outdoor heat‑dissipation unit The outdoor unit handles heat dissipation for the whole system. Dust buildup on filter screens and limescale deposits inside water pipes block heat dissipation and sharply reduce cooling capacity.
Dirty and blocked heat exchanger of the indoor unit The built‑in water‑pipe heat exchanger inside the indoor unit accumulates grime over time. Blockages lower heat transfer efficiency and prevent cold air from circulating properly.
Increased heat sources in the workshop Additional production equipment installed later generates more heat. The air conditioner cannot keep up with rising heat output, so the workshop fails to cool down.
Impact of plant environmental conditions Roof‑top placement, western exposure and poor workshop insulation allow constant hot outdoor air to flow in. This raises the cooling load and makes temperature control difficult.
Simple self‑check tips When cooling weakens, first verify whether the outdoor unit lacks water or suffers from limescale blockages, then clean the indoor filter screens. Do not rush to call maintenance technicians. Most issues can be fixed with simple cleaning!
