A Unité de condensation refroidie par air
A factory-assembled outdoor refrigeration unit that rejects cleanroom cooling loads directly to ambient air and supplies liquid refrigerant to a remote DX coil.
- Direct Ambient Heat Rejection
- Staged Scroll Compression
- Weather-Resistant Cabinet
- Remote DX Coil Service
Introduction de produit
The air-cooled condensing unit combines scroll compressors, a finned outdoor condenser, axial fans, refrigerant controls and electrical protection in one weather-resistant enclosure. It connects to a remote evaporator coil in an air-handling unit, keeping compressor noise and rejected heat outside the controlled area. Independent refrigerant circuits and staged fan control can follow varying sensible and latent loads while accessible service panels simplify routine inspection.
Key Features
Tandem scroll circuits allow capacity steps and retain partial cooling when one circuit is isolated.
Separate liquid and suction service connections support remote AHU evaporators and properly routed field piping.
Removable coil guards and hinged control access keep fans, compressors and electrical components serviceable from the perimeter.
Préoccupations du client produit
Outdoor condensers must reject a variable cleanroom load without introducing cooling water or compromising refrigeration reliability.
A mechanical room has no condenser-water loop or cooling-tower connection.Axial fans move ambient air across the condenser coil, eliminating condenser-water pumps and treatment equipment.
A single compressor cycle creates unstable supply-air temperature at low load.Multiple scroll stages and fan steps provide smaller capacity increments for steadier remote-coil control.
Long refrigerant runs can cause oil-return and pressure-drop problems.Properly sized suction and liquid connections, receivers and service valves support engineered remote-evaporator piping.
Outdoor coil fouling raises head pressure and power demand.Full-face coil guards and perimeter access allow inspection and cleaning without dismantling the cabinet.
