Systems and methods utilize a cogeneration system for providing heating, cooling, and/or electricity to an enclosure. The system includes a heat engine for heating and supplying electricity to the enclosure through fluid transfer from the heat engine to the enclosure to transfer thermal energy from the fluid to the enclosure. The system further includes a heat pump configured to supply at least heating and cooling to the enclosure through movement of fluid from the heat pump to the enclosure to transfer thermal energy from the fluid to the enclosure.

Systems and methods utilize a cogeneration system for providing heating, cooling, and/or electricity to an enclosure. The system includes a heat engine for heating and supplying electricity to the enclosure. Coupled to the heat engine is a first conduit configured to transfer fluid from the heat engine to the enclosure to transfer thermal energy from the fluid to the enclosure. The system further includes a heat pump configured to supply at least heating and cooling to the enclosure. Coupled to the heat pump is at least a second conduit. The second conduit is configured to move fluid from the heat pump to the enclosure to transfer thermal energy from the fluid to the enclosure.

A combined heat and power system generates energy and efficiently captures a percentage of such energy that would otherwise be lost to, among other things, control the temperature and humidity of a house or dwelling.

There is herein described energy storage systems. More particularly, there is herein described thermal energy storage systems and use of energy storable material such as phase change material in the provision of heating and/or cooling systems in, for example, domestic dwellings.

The integrated solar absorption heat pump system includes an absorption heat pump assembly (AHPA) having a generator, a condenser in fluid communication with the generator, an evaporator/absorber in fluid communication with the condenser and the generator, and a heat exchanger in communicating relation with the evaporator/absorber; a solar collector in fluid communication with the generator of the AHPA; a photovoltaic thermal collector in communicating relation with the evaporator/absorber of the AHPA; a plurality of pumps configured for pumping a fluid throughout the system to provide the desired heating or cooling; a power storage source, e.g., a solar battery, in communicating relation with the photovoltaic thermal collector; and a coil unit in communicating relation to the evaporator/absorber for receiving an air-stream. The absorption heat pump assembly can include an absorber and a solution heat exchanger.

An electric water heater tank adapted for connection to a controller, the tank including one or more electrical heating elements temperature sensing means mounted on the exterior of the tank wall and adapted to obtain a measurement of the temperature of the water in the tank, the temperature sensing means and each heating element being connected to an externally accessible connection means. The tank can include one or more heating element control means each connected to a corresponding one of the heating elements. The element control means can be connected to the externally accessible connection means.

A combined heating and power system is configured to generate energy as well capture a large percentage of energy that would otherwise be lost using components, including heat transfer components, embedded within a vessel to transfer energy in the form of heat to liquid within the vessel.
