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

Abstract

This project work depicts detailed operation of water heating with evacuated tube solar collector has been evaluated experimentally and mathematically. The main source of energy is the renewable energy that does not affect the environment. In order to observe the performance of solar powered water heating system, a precise model of the solar water heating system has been developed. Detailed mathematical analysis is conducted using the developed model considering the obtained experimental data on various parameters such as circulation system, changes of temperature in the collector area, number of storage tank and insulation volume, piping size and mass flow rate of water and ground reflectance those are responsible to assess and evaluate the performance analysis of the solar hot water system. Efficiency of evacuated tube collector and storage tank insulation has been calculated for any changes in size and volume. This project also demonstrates that the produced mathematical model can also be used to obtain numerical solar fraction considering the effects of any changes in the size of a collector and storage tank insulation due to the changes in temperature and mass flow rate of water. Overall efficiency of solar evacuated tube collector is proposed using the produced model for the solar heating system and also annual simulations have been conducted for a typical multifamily installation to assess the performance of the system throughout the year.
