Note:
There are two basic configurations of a thermal storage tank in a solar cooling facility. These are Stratification and Wellmixed configuration. Experimental results show that for solar cooling applications, having a well-mixed temperature in the
thermal storage tank produce more daily cooling energy than in a stratified one, although the solar field efficiency is lower.
This gives the facility more autonomy of operation in the afternoon, when the sun goes down and radiation is not enough for the application and there is still a considerably amount of thermal load in Spanish dwellings. Effects on the facility produced
by Well-mixed configuration are: efficiency reduction on the solar collector’s field, 0,27, higher daily COP’s, 0,33 , and extended solar cooling time of about two hours.
