Abstract
In this paper, we study on the theoretical analysis for practical application of the basic one which was already reported in the part (I). First of all, we reduce some calculating methods for the output water temperature of the thermal storage tank, using the following response coefficient of water temperature ε. [numerical formula] These methods are (1) an accurate method by an electronic computer, (2) a method by a close approximate equation and (3) a method by calculating charts formed on diverse thermal load patterns. Secondly, we produce the analysis for frequency response as a useful method in case that load input is expressd by frequency functions. And last, we produce a calculating method for thermal response, and Investigate the influence of heat gain and loss of the thermal storage tank on indicial response and frequency response. Thus it is proved that insulation covering the thermal storage tank set underground is useless except upward side.
