This formula uses 4 Variables

Variables Used

Theoretical Coefficient of Performance - Theoretical Coefficient of Performance is the ideal performance of a vapour compression refrigeration cycle under ideal conditions without losses or inefficiencies.
Enthalpy of The Vapour Refrigerant at T1 - (Measured in Joule per Kilogram) - Enthalpy of The Vapour Refrigerant at T1 is the total heat content of the refrigerant vapour at the initial temperature point in a vapour compression refrigeration cycle.
Sensible Heat at Temperature T3 - (Measured in Joule per Kilogram) - Sensible Heat at Temperature T3 is the heat energy required to change the temperature of a substance at a specific temperature point T3.
Enthalpy of The Vapour Refrigerant at T2 - (Measured in Joule per Kilogram) - Enthalpy of the Vapour Refrigerant at T2 is the total heat content of the refrigerant vapour at the second point in the vapour compression refrigeration cycle.

STEP 1: Convert Input(s) to Base Unit

Enthalpy of The Vapour Refrigerant at T1: 260 Kilojoule per Kilogram --> 260000 Joule per Kilogram (Check conversion here)
Sensible Heat at Temperature T3: 90 Kilojoule per Kilogram --> 90000 Joule per Kilogram (Check conversion here)
Enthalpy of The Vapour Refrigerant at T2: 350 Kilojoule per Kilogram --> 350000 Joule per Kilogram (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

COP_th = (h₁-h_f3)/(h₂-h₁) --> (260000-90000)/(350000-260000)

Evaluating ... ...

COP_th = 1.88888888888889

STEP 3: Convert Result to Output's Unit

1.88888888888889 --> No Conversion Required

FINAL ANSWER

1.88888888888889 ≈ 1.888889 <-- Theoretical Coefficient of Performance
