Outdoor air handling system of liquid desiccant combined with heat recovery of exhaust air

The system employs the technique of temperature & humidity independent processing, improving the chilled water temperature for air conditioning. Presents respectively the psychrometric chart and system flow chart of the outdoor air handling system by single liquid desiccant system and liquid desiccant combined with enthalpy exchanger. With an actual energy efficient retrofit example, analyses the energy conservation effect and emission reduction. The result shows a favorable effect of 1.36 GJ/h energy conservation and 132.5 kg/h emission reduction in the design condition.
