Refrigerant Calculator brings saturation pressure/temperature conversion, refrigeration cycle analysis and floating setpoint estimates together in one app for refrigeration technicians, engineers and students. PRESSURE AND TEMPERATURE • Convert pressure to saturation temperature or temperature to pressure. • Search an offline library of 163 fluids and mixtures by name, code or formula. • Choose gauge or absolute pressure and work with bar, psi, kPa, MPa, °C, °F and K. • Select dew or bubble point for mixtures and consult available fluid properties and operating ranges. REFRIGERATION CYCLES • Analyze single-stage and two-stage cycles with real-fluid thermodynamic properties from CoolProp. • Review cooling capacity, compressor power, COP, mass flow and thermodynamic states. • Use pressure-ratio-based efficiency estimates within their supported ranges, or enter an isentropic efficiency. • Find the intermediate condition that minimizes total compressor power in the two-stage model. Compare a manual setting with the model optimum in kW and percent. • Export a PDF calculation report with inputs, results, equations, assumptions and references. OTIMIZ IUS Explore intelligent floating setpoint scenarios and estimated energy and cost savings. In this version, this module is limited to R717 (ammonia) and available Brazilian locations. Results depend on the entered operating conditions and assumptions. Worldwide support for Otimiz ius is coming soon. EVERYDAY USE • Keep calculation history and favorite conversions or cycles on your device. • Switch between light and dark themes. • Use the interface in Portuguese, English or Spanish. • Perform calculations offline without creating an account. The results support technical analysis and do not replace equipment manufacturer data, applicable standards or professional assessment. Cycle results describe the selected model and assumptions; they are not measured equipment performance.
