Abstract

Energy is a prime requirement of modern society. the use of energy from finite fossil fuels is recognized as changing the global climate through the excessive release of greenhouse gases. In India, from buildings consume 47% of the primary energy while industry and agriculture account for 28% and transportation 25%. In buildings 2/3rd of the energy need comes from dwellings and the remaining 1/3rd comes from commercial activity. cooling is the basic need for buildings in hot and sunny climates in Indian regions and during, summer season, in hot climates there is an increase in electricity consumptions due to cooling load. Indian country facing an electricity shortage crisis which becomes worse in summer due to high demand for cooling. The advancement of technology in domestic comfort specially indoor circulation of conditioned air has resulted in an escalation of household energy consumptions in India specially in summer and due to extensive use of cooling load. Due to high demand for cooling, a country wide energy crisis is witnessed during this time. In this research, a solar water heating of a residential house using the abundant and universal sources is proposed for a residentials house in India for mitigating this energy shortage and for offering a sustainable solutions to the problem. The paper presents a mathematical model of the house on TRNSYS simulation software along with the simulation results of coupling of the several components operating in parallel with the cooling systems. The results demonstrated that, the proposed model of household solar cooling system may be satisfactory used for a residential house or HVAC systems in Indian scenario. The system was modeled using TRNSYS software and its components to represent the various parts of the solar heating system. Assumptions, modelling of different components and their limitations of simulations have been depicted as per the requirement of the proposed research work.
