HVAC/Refrigeration Engineer

zero-to-one product R&D journey

• Designing the

  complete vapour compression refrigeration cycle

  for a water-cooled AC system
• Thermodynamic modelling and optimization of:
• Compressor (scroll, rotary, or BLDC)
• Condenser (shell-and-tube, plate)
• Evaporator coil (DX type or flooded)
• Radiator heat exchanger (air-water, fan-assisted)
• Expansion device (TXV, capillary)
• Designing a

  closed-loop water cooling circuit

  with pump and radiator sizing
• Simulating airflow and heat rejection using:

• CFD tools

  (e.g., ANSYS Fluent, SolidWorks Flow Simulation, OpenFOAM)

• Thermal system solvers

  (EES, CoolProp, TRNSYS, or similar)
• Creating physical models for:
• Water-side and air-side pressure drop
• Heat transfer coefficients (film, convective, fin)
• Radiator surface efficiency
• Supporting CAD design, prototype layout, testing, and instrumentation
• Conducting controlled tests for temperature drop, power consumption, and COP estimation

• Degree in Mechanical / Thermal / HVAC / Energy Engineering (M.Tech/B.Tech)
• Strong theoretical grounding in:
• Vapour compression cycle
• Heat exchangers (air-water, water-water)
• Fluid flow & thermodynamics
• 3–5 years of experience in HVAC or refrigeration product development

• Hands-on experience in CFD simulation and thermal modelling tools

  :

• ANSYS, SolidWorks Simulation, OpenFOAM, EES, or equivalent

• Familiar with refrigerant properties (R410a, R32, R290) and selection criteria
• Good understanding of system COP, compressor loading, and delta-T optimization
• Bonus if experienced in:
• Prototype building and lab testing
• BLDC/EC fans, microchannel heat exchangers, or PCM-based cooling

• You'll work on

  first-principles R&D

  , not just assembling catalogs
• Build a

  closed-loop, energy-saving cooling product

  with real-world impact
• Collaborate directly with the founder on every design iteration
• Influence product IP, filing patents, and performance benchmarks
• Potential leadership or full-time CTO-level track for long-term contributors
