CWS DC Inverter DC35 RC

Typowe problemy

• Refrigerant undercharge or overcharge from field servicing without proper evacuation
• Seawater-cooled condenser fouling or scaling reducing heat rejection
• Compressor drive/inverter fault codes triggered by onboard supply voltage fluctuation
• Seawater pump impeller wear or airlock reducing condenser water flow
• Refrigerant leaks at brazed joints from vibration over time
• Condensate drain blockage causing water ingress into cabin spaces

Lista kontrolna przeglądu

• Electronic leak detection at refrigerant joints and fittings
• Suction and discharge pressure measurement against manufacturer's target range for the ambient/seawater condition
• Seawater strainer inspection and cleaning
• Condenser flow rate and tube-side cleanliness check, acid-clean if scaled
• Compressor current draw check against nameplate rating
• High/low pressure safety cutout function test
• Electrical connection and terminal tightness check
• Condensate drain and insulation check for leaks or sweating

Zakresy są typowe dla tej klasy konstrukcyjnej. Decydujące są zawsze dokumenty producenta dla danego numeru seryjnego.

Krytyczne części zamienne

• Seawater pump (complete, or impeller/seal kit)
• Filter drier
• High/low pressure safety switches
• Compressor (inverter-matched, long lead time)
• R410A refrigerant plus recovery/charging equipment

Bezpieczeństwo

• Refrigerant under pressure - frostbite/injury risk on accidental release
• Electrical hazard at compressor terminals and inverter drive
• Hot surfaces at the compressor discharge line
• Limited access in the machinery space where units are typically installed

Przegląd klasyfikacyjny

Air conditioning plant is not normally a classed item in itself. Refrigerant systems above certain charge quantities may fall under environmental/ODS regulation (F-Gas or equivalent) requiring logged leak checks and certified technicians. Where the unit interfaces with fire dampers in the accommodation ventilation system, that interface remains subject to normal fire safety survey.

Szacowana trwałość: Marine DC inverter chillers of this class are generally expected to give 8-15 years of service under normal yacht duty cycles with proper maintenance; compressor life is condition-dependent rather than a fixed hour figure - confirm against manufacturer's warranty/design documentation.
