Refrigeration Workflow

Bring thermodynamic states from your trusted refrigerant property source. Abecator connects them into superheat, subcooling, compressor efficiency, refrigeration effect, mass flow, COP, capacity and cycle energy-balance checks.

01 — SATURATION & LINE TEMPERATURES

Define superheat and subcooling references.

Use saturation temperatures from the same refrigerant property source as the enthalpy states. For blends, apply the correct bubble/dew convention.

02 — CYCLE ENTHALPIES

Supply states 1–4 from the same property model.

Typical convention: 1 compressor inlet, 2 actual compressor outlet, 2s isentropic outlet at discharge pressure, 3 condenser outlet, 4 expansion-device outlet.

03 — SYSTEM SIZE

Choose mass-flow or cooling-capacity basis.

Calculation basis Refrigerant mass flowkg/sCapacities are solved from the supplied refrigerant mass flow.

No refrigerant property values are guessed by this workflow. Your temperatures and enthalpies stay in the browser and are not collected by anonymous analytics.

Superheat / subcoolingInspect saturation-reference temperature differences separately. Compressor efficiencyCheck the enthalpy-based compressor relation independently. COP & capacityFocus on cooling capacity, power and COP. Vapor-compression cycleInspect the cycle enthalpy balance independently.

PROPERTY-PACKAGE INDEPENDENT

The workflow checks the cycle. It does not pretend to be a refrigerant database.

That separation matters. Saturation states and enthalpies should come from a trusted source appropriate to the refrigerant, blend convention and pressure range.

Abecator then applies transparent energy relations to check whether those states form a coherent engineering cycle.

Temperature margins. Saturation and line temperatures produce superheat and subcooling.

Compression. h1, h2s and h2 produce isentropic efficiency and compressor work.

Cycle performance. h1–h4 produce refrigeration effect, COP and mass-flow/capacity scaling.

Balance. Evaporator + compressor should reconcile with condenser duty for one consistent cycle state.
