“…The exergy analysis of a passive solar still combined with heat storage system is presented in meteorological conditions taken at Errachidia city (Latitude: 31°58'N, Longitude: 4°20'W, Morocco) by Mohamed Asbik [13], to determine the magnitude of exergy losses during the heat storage/retrieve period. Paraffin wax is used as phase change material (PCM) to store/retrieve energy in the process of changing the aggregate state from solid to liquid.…”

In this paper, an effort has been made to evaluate the convective heat transfer coefficient and mass of water evaporated from a single slope passive solar still for different water depth (0.01, 0.015, 0.02 and 0.025 m) by various thermal models like Dunkle's model, Chen et al.'s model, Clark's model, Adhikari et al.'s model, Kumar and Tiwari's model, Zheng Hongfei et al.'s model and Tsilingiris model. These models were studied and compared with the experimental work. Also, the energy and exergy efficiency were calculated and the percentage deviation between experimental and theoretical prediction also listed out. The experimental validation of energy and exergy efficiency using different thermal models was carried out at Chennai, Tamil Nadu, India. By comparing the theoretical values of the hourly yield with the experimental data it was found that Dunkle's, Chen et al.'s model and Tsilingiris model gave better conformity between the forecasted and experimental results. Kumar and Tiwari's model yield is very high where as Clark's model, Adhikari et al.'s model and Zheng Hongfei et al.'s model predicts lower values as compared with the experimental results.

Pure and fresh water is being scarce day by day. Although Bangladesh is a riverine country, pure drinking potable water is not a cheap commodity. Most of the people in the cities boil water to drink, and people of the villages take tube-well's water directly, which might have high amount of heavy metal like arsenic. Solar still is a cheap and very useful renewable technology, which can be used in Bangladesh extensively everywhere at the rooftop as a pure water source. Objective of this paper was to find a low cost portable and easily maintainable passive solar still for southern part of Bangladesh. All the parameters of passive solar still are studied, and it is found that an inclined stepped solar still with passive condenser, internal and external reflectors, black cotton wick, and with optimum design values can be the desired still, which would give maximum yield. Finally, the optimum values of the parameters are used to propose a cheap design.

A humidification-dehumidification (HDH) solar desalination process with active and passive air circulation is proposed, in which the phase change material (PCM) is used to recover the latent heat of vapor condensation to increase the fresh water production. The experiments show that the cost of fresh water is 23.47 Yuan/t, the gain output ratio of the unit is 13.37, and the water production is increased by 84.4% compared with the dehumidifier without using PCM. The heat transfer between the heat pipe and the PCM (I) (paraffin) and the high thermal conductivity PCM (II) are tested and simulated.
