This formula uses 4 Variables

Variables Used

Enthalpy of the Vapour Refrigerant at T1 - (Measured in Joule per Kilogram) - Enthalpy of the vapour refrigerant at T1, i.e at the suction of the compressor.
Liquid Enthalpy at Point 1 - (Measured in Joule per Kilogram) - Liquid enthalpy at point 1 is the enthalpy at the saturated liquid line.
Dryness Fraction at point 1 - Dryness Fraction at point 1 is used to quantify the amount of water within the steam at point 1.
Latent Heat of Fusion - (Measured in Joule per Kilogram) - Latent Heat of Fusion is the amount of heat required to convert one unit amount of substance from the solid phase to the liquid phase — leaving the temperature of the system unaltered.

STEP 1: Convert Input(s) to Base Unit

Liquid Enthalpy at Point 1: 100 Kilojoule per Kilogram --> 100000 Joule per Kilogram (Check conversion here)
Dryness Fraction at point 1: 0.1 --> No Conversion Required
