Design and Performance Evaluation of Solar Liquid Desiccant System

Human comfortness is essential now a day because of the improvement in life style and increasing atmospheric temperature. Electrical air conditioning machines are not most suitable for large buildings because of the higher power consumption and shorter life. Central air conditioning or chilled water system is more reliable for easy operation with a lower maintenance cost for large building. With large buildings such as commercial complex, auditorium, office buildings are provided with central air conditioning system. Educational and research institutions, Hotels, Hospitals, malls etc. are also need human comfortness, as the population of student community increase year by year. The effective design of central air conditioning or a chiller system can provide lower power consumption, capital cost and improve aesthetics of a building. This paper establishes the results of cooling load calculation of different climate conditions by installing dehumidifier. By using CLTD method and Carrier program then the results are compared for a single-story building which is a part of an institute. Cooling load items such as, Electrical equipments, people heat gain, lighting heat gain, infiltration and ventilation heat gain can easily be putted to the MS-Excel programme. The programme can also be used to calculate cooling load due to walls and roofs. And results were compared with the standard data given by ASHRAE and CARRIER Fundamental Hand Books, hourly analysis programme and results are satisfactory. It is also seen that in this paper cooling requirement of without dehumidifier is about 20 % more as compare to with dehumidifier for climate condition of Thiruvanathapuram, Kerala in India. It will be a significant for a large commercial building.
