Abstract

A modified open regeneration system suitable for humid climates is proposed. The upper part of the open solar regenerator is covered with a single glazing where the desiccant can be heated without water evaporation. Evaporation starts at the beginning of the open surface. For this type of regenerator, the regeneration efficiency is defined as the ratio of energy used to evaporate water from the open surface to the total radiation falling on the glaze and open surfaces. The effect of flow length of the regenerator (for the glaze and open surfaces) has been taken into consideration in evaluating regeneration efficiency. Effects of some of the operating parameters are briefly discussed in this paper.
