Refrigeration Cycle Calculator
Calculate COP, refrigeration capacity, compressor work, and system efficiency for vapor-compression refrigeration cycles.
Step 1: Temperature Parameters
Typical Temperature Ranges
Evaporator: -40°C to 10°C. Condenser: 30°C to 60°C. Ideal refrigeration cycle assumes isentropic compression and constant pressure heat transfer.
Step 2: System Parameters
Performance Metrics
COP (Coefficient of Performance) = Cooling Effect / Compressor Work. Higher COP indicates better efficiency. Typical COP range: 2.0-5.0.

Carnot COP Reference
Carnot COP = T_evap / (T_cond – T_evap) [in Kelvin]. Actual COP is always lower due to irreversibilities.
Refrigerant Properties at Operating Conditions
Refrigeration Cycle Formula
COP = Q_evap / W_comp = (h₁ – h₄) / (h₂ – h₁)
Where h₁ = enthalpy after evaporator, h₂ = enthalpy after compressor, h₄ = enthalpy after expansion valve. Based on vapor-compression cycle with isentropic compression.
