Air at 30 °C, 1.05 bar, and 80% relative humidity enters a dehumidifier operating at steady state. Moist air exits at 15 °C, 1 bar, and 95% relative humidity. Condensate exits in a separate stream at 15 °C. A refrigerant flows through the cooling coil of the dehumidifier with an increase in its specific enthalpy of 100 kJ per kg of refrigerant flowing. Heat transfer between the humidifier and its surroundings and kinetic and potential energy effects can be ignored. Determine the refrigerant flow rate, in kg per kg of dry air.

Question
Air at 30 °C, 1.05 bar, and 80% relative humidity enters a dehumidifier operating at steady state. Moist air
exits at 15 °C, 1 bar, and 95% relative humidity. Condensate exits in a separate stream at 15 °C. A refrigerant
flows through the cooling coil of the dehumidifier with an increase in its specific enthalpy of 100 kJ per kg of
refrigerant flowing. Heat transfer between the humidifier and its surroundings and kinetic and potential
energy effects can be ignored. Determine the refrigerant flow rate, in kg per kg of dry air.
