Abstract

The preservation of natural water and electricity resources is essential for the development of smart cities. Indeed, water and electricity are highly dependent and must be analyzed together to improve the energy efficiency. This article is about the study of the integration of renewable energy and smart solutions in a water heating system. The existing system uses mainly heat pumps to cover the most of the hot water needs. The purpose of this work is to explore possible solutions to optimize the electricity and the water consumption of the installation.

3. Insertion Of Solar Thermal System

3.1 Description of a Solar Thermal System

Solar thermal system is generally divided into 5 subsystems (Ministry of Housing and Urban Policy, n.d.):

  • •

    Collection: a set of solar collectors that transform solar radiation into thermal energy.

  • •

    Transfer: a solar hydraulic circuit that connects the collectors to each other and distributes energy throughout the entire system.

  • •

    Storage: solar storage tanks.

  • •

    A back-up system (electric): it provides the necessary energy to guarantee at all times the hot water needs, especially during periods of low sunlight.

  • •

    Regulation: A device for regulating, measuring and controlling the system.
