Abstract: A water energy conversion system includes a control unit, a first gas-water energy conversion device, a second gas-water energy conversion device, a water supply device, a storage tank and a heat source unit. Water for different purposes is supplied by the water supply device that collects and transmits various kinds of water resources. Operations of the storage tank as well as the first and second gas-water energy conversion devices are based on water as the basis and a carrier of energy conversion to provide effective energy conversion and recycling. By further employing the heat source unit, high-efficiency cooling, heat dissipation or heat absorption can be achieved with minimal power and water consumption. Thus, the water energy conversion system is applicable for energy conversion, energy regulation and supply for air of indoors and outdoors of a building to realize effects of water storage and supply, anti-flooding, and energy saving and storage.

Abstract: A building energy storage and conversion apparatus includes at least a control unit, an electric power conversion unit, an energy conversion unit and a thermoelectric conversion unit to regulate energy sources of the electric power conversion unit. The energy conversion unit generates cold/heat energy which is stored through a heat storage equipment (for cold/heat energy). The cold/heat energy can be released when needed. When the cold/heat energy is in a surplus state, it can be converted to electric power through the thermoelectric conversion unit or stored in the form of electric power. Thus energy resources can be converted and utilized in an optimal fashion to achieve energy self-sufficiency of a building. Moreover, energy exchange with other buildings in the neighborhood can be done to balance demand and supply.
