Compresor de tornillo chiller
A medium-to-large liquid chiller using twin-rotor screw compression for robust continuous-duty cooling and smooth capacity control.
- Twin-Rotor Screw Compression
- Continuous Capacity Control
- High-Capacity Cooling
- Air- or Water-Cooled Options
Introducción del producto
The screw compressor chiller uses meshing helical rotors to compress refrigerant continuously, providing fewer capacity pulses than reciprocating machinery and reliable operation at medium and large duty. Slide-valve or variable-speed control follows changing chilled-water load, while an economizer can improve capacity at favorable operating conditions. The compressor can be paired with air-cooled condenser coils or a water-cooled shell-and-tube condenser. Oil management, discharge temperature and evaporator flow are supervised by the unit controller.
Características clave
Slide-valve or variable-speed modulation adjusts capacity without relying only on start-stop cycling.
Economizer and liquid-injection options can support capacity and compressor temperature control.
Air-cooled and water-cooled arrangements allow the compressor platform to match the available heat sink.
Preocupaciones del producto del cliente
Screw chillers perform best when oil management, minimum load, water flow and condensing conditions remain within the compressor operating envelope.
Low plant load forces frequent compressor starts.Variable capacity and correctly sized system volume maintain longer stable operating cycles.
Oil remains in the evaporator during prolonged low-load operation.Oil separation, return control and minimum refrigerant velocity protect compressor lubrication.
Sudden process load changes cause chilled-water temperature excursions.Fast capacity modulation and leaving-water control respond without waiting for another compressor stage.
High discharge temperature limits operation at extreme conditions.Economizer, liquid injection or appropriate condensing control keeps the compressor within its map.
