Key Responsibilities

• Design, install, commission, and troubleshoot refrigeration and cooling systems.
• Strong knowledge of refrigerants, refrigeration cycles, and refrigerant properties.
• Perform cooling load calculations, heat-load calculations, compressor capacity calculations, and system sizing.
• Select suitable compressors, condensers, evaporators, expansion valves, and other refrigeration components.
• Handle refrigerant charging, recovery, vacuuming, leak testing, and system evacuation.
• Diagnose issues related to high/low pressure, superheat, subcooling, temperature fluctuations, compressor performance, and refrigerant flow.
• Knowledge of single-stage and cascade refrigeration systems will be preferred.
• Hands-on experience with compressors such as Bitzer, Copeland, Danfoss, SECOP, Embraco, Tecumseh, etc.
• Good knowledge of refrigerants such as R404A, R134a, R407C, R410A, R290, R23, R508B, etc.
• Strong knowledge of centralized AC systems, including chilled-water systems, AHU, FCU, cooling towers, chillers, pumps, and related HVAC equipment.
• Perform HVAC cooling-load calculations and equipment capacity selection.
• Troubleshoot centralized AC and refrigeration systems and identify root causes of failures.
• Prepare technical reports, maintenance schedules, and system performance reports.
• Ensure proper preventive and corrective maintenance of refrigeration and HVAC systems.
• Coordinate with production, service, and R&D teams for equipment installation and troubleshooting.

Required Technical Skills

• Strong understanding of refrigeration cycles and thermodynamics.
• Excellent calculation and analytical skills related to refrigeration and HVAC systems.
• Knowledge of TR calculation, BTU/hr, kW cooling capacity, CFM, airflow, temperature difference (T), superheat, subcooling, and pressure-temperature relationships.
• Good understanding of compressor, condenser, evaporator, expansion valve, and refrigerant piping selection.
• Knowledge of centralized AC/chiller systems.
• Ability to read and understand P&ID, refrigeration circuit diagrams, electrical/control diagrams, and technical drawings.
• Knowledge of temperature controllers such as Dixell, Carel, Elitech, etc., will be an advantage.

Qualification

• B.E./B.Tech/Diploma in Mechanical Engineering, Refrigeration & Air Conditioning, HVAC, or a related field.
• 3+ years of relevant experience in refrigeration, HVAC, centralized AC, chillers, cooling systems, or low-temperature equipment.
