This book was released on 2015 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gas instantaneous water heaters are increasingly used as auxiliary energy sources for renewable energy domestic hot water systems. Currently the gas used by these systems is measured and modelled only very approximately. Accurately assessing consumption is important as gas can supply up to 50% of the energy. Gas auxiliaries used in these arrangements are also predominantly designed as stand-alone devices and typically integrated into renewable systems in a very basic manner. This research seeks to fill two important gaps. First, how does the gas instantaneous water heater actually perform as part of a renewable water heater? Second, once performance can be measured and modelled accurately, what improvements in energy use might be made through novel ways of integrating the gas auxiliary with the renewable energy water heater? This study adopts a broad approach in examining these gaps. A number of existing test methods for gas instantaneous, air source heat pump, solar and electric storage water heaters are reviewed in detail. A number of different gas instantaneous water heater test standards are compared experimentally. The effect of water use patterns on the energy use of various water heating technologies is investigated both experimentally and with modelling. The carbon emissions of a number of different types of water heater is calculated after a detailed review of CO2 emissions of the New Zealand electricity generating system during both dry and wet years. A new experimental test method is developed to characterise the steady state performance of a gas instantaneous water heater. This performance characterisation is then used in a TRNSYS model together with established models of renewable energy water heaters to predict energy consumption. Integrated systems using novel control and hydraulic connection arrangements are then compared to other water heating systems. The current methods of determining the gas consumption of auxiliary water heaters may understate energy use by as much as 15%. Improved control system integration saves an average of 17% in energy and 11% in carbon dioxide emissions compared to other high efficiency water heating systems. Improved hydraulic arrangements result in 4.5% savings. The change in energy conversion ratio with differing water use patterns of some water heaters can exceed the differences exhibited between technology types and competing models of similar technology. If consumers are to choose their water heaters based on comparable running costs or emissions, accurate measurement and modelling of gas auxiliaries is required. Current test methods do not appear to provide the required accuracy. There are also opportunities for significant improvement in energy use through better integration of gas auxiliaries with renewable energy residential water heating systems.
Book Synopsis Electrification of Domestic Hot Water to Aid the Integration of Renewable Energy in the California Grid by : Alejandro Cervantes
Download or read book Electrification of Domestic Hot Water to Aid the Integration of Renewable Energy in the California Grid written by Alejandro Cervantes and published by . This book was released on 2020 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water heating in residential buildings, also known as domestic hot water (DHW), is the third largest use of energy after appliances and space conditioning. About 90% of the residential buildings in the state use natural gas fueled water heaters, 6% use electricity, and a small percent use liquefied petroleum gas (LPG) or solar water heaters. The current energy use associated with residential water heating is small relative to the total amount of energy consumption in the residential building sector, but it is still a contributor of greenhouse gas (GHG) emissions. Improving hot water systems can be beneficial for bill customer savings, energy use, and water savings. Heat pump water heaters (HPWH) can function as grid batteries by using the water tank capability of thermal storage. The use of aggregated electrical DHW systems to store extra electricity during peak generation times or during low utility time of use (TOU) rates has the potential to alleviate some of the curtailed renewable energy power generation sources in the California grid while reducing carbon emissions and customer cost. Water heating technology was simulated using the Building Energy Modeling software California Building Energy for Code Compliance (CBECC-Res) and the California Simulation Engine (CSE). Different climate zones were explored to compare the electricity needed for a water heater operation given the same input parameters of water draw profiles and building envelope. The results show the feasibility of using HPWH and ERWH technology to participate in demand response management programs. The demand response capability of HPWH and ERWH show that they could be useful tools to accommodate surplus energy from solar generation during the solar peak hours. Whether the demand response is implemented using traditional HPWH or ERWH units, the capability of the technology to act on control signals is a necessary condition for a successful program.
