Webrefrigerant (two-phase mixture) is evaporated to a saturated vapor at state point 1. The latent enthalpy necessary for evaporation is supplied by the refrigerated space surrounding the evaporator. The amount of heat transferred to the working fluid in the evaporator is called the refrigeration load. qL = h1 − h4 Notes: basil mix ai 使い方WebREFRIGERATION CYCLE • Pressure-enthalpy chart – Used to create a graphical representation of a system – Pressure scales on the vertical axis (psia) – Enthalpy scale along the bottom of the chart – Horseshoe curve represents the saturation curve – Refrigerant is saturated on and under the curve • Enthalpy is defined as heat content basil moreau hallWebSpecific enthalpy (kJ/kg) Specific entropy (kJ/kg-K) Temp.
