Problem Dimension Mapping
表格
Problem Dimension
Problem Type
Procurement & model selection
Power mismatch between condensing unit and air cooler; confusion among L‑Box / V‑Box / U‑type / H‑type condenser; mis‑selection of hydrophilic aluminium fin specification; wrong evaporator type (DD‑7 / DD‑100) for cold room temperature; mis‑judge cabinet‑type vs open‑type condensing unit application boundary
Installation & construction
Wall‑mount all‑in‑one unit wall load‑bearing risk; L‑box condenser ventilation obstruction; H‑type horizontal air outlet airflow short‑circuit; 15 mm copper tube welding standard; ceiling‑suspended evaporator load capacity; floor‑standing unit foundation flatness; water defrost air‑cooler drainage gradient
Working condition adaptability
Coastal salt‑fog corrosion of hydrophilic aluminium fins; high‑humidity cold room evaporator frosting frequency; fan‑less condenser FNH series ambient temperature limit; open spiral condensing unit dust‑proof requirement; stainless‑steel air cooler applicable scene threshold
Process & component failure
Copeland scroll compressor liquid slugging; hydrophilic aluminium fin fouling heat‑exchange attenuation; H/V/L/U type heat exchanger partial blockage; air‑cooler rounded‑edge casing condensate accumulation; multi‑fan motor evaporator single‑motor failure cascade effect; water‑defrost system blockage
Maintenance & common misconceptions
Maintenance cycle for galvanized sheet cabinet condensing unit; mis‑operation for fan‑less condenser FNH‑12; improper defrost parameter setting for DD‑series air cooler; mixing compressor oil types; vacuum‑pumping threshold before commissioning; misjudge between cabinet‑type and open‑type unit later‑stage maintenance cost
Custom‑made project risk
Custom condensing unit parameter verification risk; mismatch between custom air‑cooler fan quantity and cold‑room volume
