The role of control optimization in improving the operation of solar water heating systems in green buildings

Due to the increasing decline in fossil fuels such as oil and gas and the pollution caused by these fuels , the use of renewable energy to meet energy needs is nowadays considered as one of the cheapest and cleanest solar energy. It is of particular importance. Among solar systems , domestic hot water supply systems with solar thermal water heaters are more in demand , which requires further research to increase efficiency and reduce the cost of these systems. Solar water heating systems (SWH) are well known and effective structures that transfer solar energy to heat. In this paper, the water consumption of buildings using solar energy (solar water heaters) is discussed. The advantage of this paper over other papers is the methods of controlling the solar water heater and simulating the temperature in different climates. The need to use new energy (solar, etc.) reduces pollution and reduces costs. This article differs from other articles in simulation and control methods. As such, this paper examines the control mechanisms. The SWH system is designed to assist the building manager in achieving targeted energy management goals. In particular, three control approaches to improve energy management have been studied by considering different scenarios in terms of the actual climate pattern and the hot water demand of a commercial building. The operational efficiency of the SWH system is also controlled by auxiliary heaters such as heat pumps and electric heaters as circulation pumps. Proposed approaches can improve operations.
