Solar Ejector Refrigeration Formulation:
• Entrainment Ratio: ω = ṁsec / ṁpri ∝ √[(Tg−Tc)/(Tc−Te)]
• Thermal COP: COPth = Q̇cool / Q̇solar_gen
• Required Solar Area: Asolar = Q̇gen / (G · ηcoll) [m²]
• Completely compressor-free thermal refrigeration.

📘 Calculation Methodology & Solar Ejector Standards

Supersonic Jet Entrainment

High-pressure motive vapor expands through a convergent-divergent nozzle to supersonic speeds ($M > 2$), creating a low-pressure zone that sucks vapor from the evaporator.

100% Thermal Drive (No Compressor)

Solar thermal energy directly powers the cycle. Only a tiny liquid feed pump is required, consuming less than $1\%$ of the electrical energy of vapor compression chillers.

Key Engineering Assumptions

  • 1D gas dynamic model of supersonic constant-pressure mixing.
  • Saturated vapor conditions at generator and evaporator exits.
  • Applicable to solar air conditioning, industrial steam ejectors, and food cold storage.
