Marine HVAC and refrigeration support

Shipboard heating, ventilation, air conditioning, provision refrigeration, chillers, and control-room cooling protect people, cargo, food, and temperature-sensitive equipment. Marine systems face salt, vibration, restricted plant space, variable seawater temperature, and limited redundancy. Attendance can cover fault diagnosis, planned service, leak repair, component replacement, refrigerant handling, duct and fan work, balancing, controls, and commissioning.

Environmental and survey context

MARPOL Annex VI regulation 12 controls ozone-depleting substances and requires relevant records for applicable installations and ships. Refrigerant recovery, purchase, charging, leakage, and disposal may also be governed by flag, port-state, and national technician-certification rules. Surveyors can review the ODS Record Book, equipment inventory, deliberate-emission controls, and evidence of approved handling. Refrigerant type must be positively identified before mixing, recovery, or charging.

Typical service scope

• Performance checks using temperatures, pressures, superheat, subcooling, current, flow, and alarm history
• Leak detection, pressure testing with an appropriate medium, evacuation, dehydration, charging, and recovery
• Compressor, condenser, evaporator, fan, pump, valve, filter-drier, thermostat, sensor, and control repairs
• Provision-room checks, defrost optimisation, insulation and door-seal inspection, air balancing, and duct cleaning support
• Commissioning report recording refrigerant movements, measurements, parts used, remaining defects, and operating condition

Prepare the service request

Provide the vessel, port, system maker and model, refrigerant, charge quantity, cooling capacity, space served, fault symptoms, alarm codes, trend readings, previous work, suspected leak, spares onboard, and sailing deadline. Confirm whether the plant can be stopped, whether food or cargo needs temporary cooling, and whether refrigerant supply or disposal is required. Good diagnostic information helps mobilise the correct gauges, recovery equipment, refrigerant, and parts on the first visit.
