Development of design charts for solar cooling systems. Part Ⅱ: Application of the cooling f-chart

摘要

This work includes the evaluation of the solar contribution in solar cooling systems by the newly developed solar cooling design chart. The effect of collector area and storage volume on the solar fraction is well taken into account in the cooling design charts. The results of several experimental installations are compared with the present cooling f-chart predictions. The agreement is very good, which verifies the validity of design predictions by the new cooling f-chart. Changing the collector area in a solar cooling system has a similar effect on the solar fraction as that in a solar heating system. Storage volume appears to show an optimum in a solar cooling system with a marked influence on the solar contribution. The cooling f-chart may be used in equation form for design purposes. Design by solar cooling design charts is applicable for different building constructions, solar collector types, length of cooling season, location and meteorological conditions.
