Abstract

Simulation of a Solar Domestic Water Heating System with Different Collector Efficiences and Different Volumen Storage Tanks

Highlights

  • During the last years of the twentieth century, extensive efforts to alleviate global warming of the earth caused by emission of carbon dioxide in atmosphere have been undertaken

  • The simulations performed by using this software, give the solar fractions for several system designs with different solar colectors and different storage volumes

  • For the simulations performed on an annual basis, the storage tank volume is investigated in the range from 50 to 300 l, and required demand water temperature at 45°C

Summary

Introduction

During the last years of the twentieth century, extensive efforts to alleviate global warming of the earth caused by emission of carbon dioxide in atmosphere have been undertaken These emissions are generated by intensive burning of fossil fuels in order to satisfy the growing energy needs of humanity. Solar systems for DHW production should be optimally designed and operated This way, the energy effectiveness of these systems are often investigated, by using experiments or through modelling and simulations [1,2]. This paper shows the results of the computer simulations carried out in order to investigate the effectiveness of a particular type of the solar system. Such a system should consist of two main elements as solar collector and a storage tank. The simulations performed by using this software, give the solar fractions for several system designs with different solar colectors and different storage volumes
