Mathematical modeling of solar domestic hot water system (SDHWS) with thermal storage tank

摘要

This paper depicts detailed operation of water heating with solar all glass evacuated tube collector has been evaluated experimentally and numerically. A precise model of the system has been advanced to observe the execution of solar powered heating system and the perfection analysis of the evacuated tube collector. The model has been considered by the experimental data on various parameters such as circulation system, changes of temperature in the collector, number of storage tank, flow rate of water and ground reflectance that are responsible to assess. Efficiency of evacuated tube collector and storage tank insulation has been calculated for any changes in size and volume. The model can also be used to obtain numerical solar fraction considering the effects of insulation regarding of changes in temperature and mass flow rate of water. Overall efficiency of solar evacuated tube collector has been obtained by using the produced model for the system and also the result has been conducted for a typical multifamily installation to measure the system performance throughout the year.
