20. Investigation of Effect of Using Evacuated Tube Solar Collector on Solar Pond Performance

The present study deals with the performance investigation of a solar pond integrated with an evacuated tube solar collector system. The experimental cylindrical solar pond system (with a radius of 0.80 m and a depth of 1.65 m) with an evacuated tube solar collector was built in Cukurova University in Adana, Turkey. The solar pond was filled with salty water of various densities to form three salty water zones (e.g. upper convective zone, non-convective zone and heat storage zone). Heat energy was collected by solar pond and evacuated tube solar collectors. The heat collected by collector was transferred to the heat storage zone of the solar pond with a heat exchanger system. Several temperature sensors connected to data acquisition system were placed vertically inside of the solar pond and inlet and outlet of the heat exchanger in the storage zone of the pond. The studies were performed using an evacuated tube solar collector integrated with the solar pond.
