A cleanroom air-conditioning package that uses a refrigerant evaporator coil for direct sensible cooling and dehumidification without a chilled-water circuit.
- Direct Refrigerant Cooling
- Matched Condensing System
- Controlled Dehumidification
- Cleanroom Filter Staging
مقدمة المنتج
The cleanroom direct-expansion air-conditioning unit combines a refrigerant evaporator coil with cleanable filters, a drainable condensate section and variable-speed supply fan. A matched outdoor condensing unit or remote condenser rejects heat without requiring a central chilled-water plant. Multiple compressor stages or inverter capacity allow the coil to follow varying cleanroom load, while reheat can stabilize room temperature during dehumidification. Refrigerant piping, oil return and coil distribution are designed for the selected distance and lift.
الخصائص الرئيسية
Variable or multi-stage compressor capacity reduces cycling under partial sensible load.
A drainable insulated coil section contains condensate produced during moisture removal.
Reheat and fan-speed control support temperature stability during latent operation.
مخاوف المنتج للعملاء
DX systems must match refrigerant capacity, air volume and coil temperature closely to avoid cycling, water carryover and unstable humidity.
A single large compressor repeatedly starts and stops at low cleanroom load.Inverter or staged compressors modulate closer to the active sensible and latent demand.
An unevenly fed evaporator leaves parts of the coil warm and reduces dehumidification.Matched distributors and expansion control maintain stable refrigerant feed across circuits.
Condensate is carried downstream during high latent load.Proper coil face velocity, eliminator clearance and a full drain pan control water.
Long refrigerant piping causes oil-return and capacity problems.Pipe size, traps and allowable lift are selected for the matched compressor and circuit.
