An energy generating system for generating thermal energy and electrical energy for a premises. The system includes an engine that drives an AC power generator to supply supplemental or standby power to the premises. The thermal energy given off by the engine is also coupled to the premises to provide heat thereto. A processor controls the various parameters of both the energy generating system and the premises to coordinate the proper heating and cooling thereof.

Building heating and/or cooling methods are provided that can include: distributing fluid from within conduits within a concrete floor of a building to conduits within grounds surrounding and/or supporting the building; diverting at least some of the fluid exiting the conduits within the grounds surrounding and/or supporting the building to a dehumidifier operably associated with the interior of the building; and returning the at least some of the fluid from the dehumidifier to the conduits within the grounds surrounding and/or supporting the building.

Systems and methods are disclosed for exchanging thermal energy between a drain liquid and a source liquid for heating or cooling of the source liquid. One method for heating a source liquid may involve transferring heat from a drain liquid using a heat pump. A system may include a refrigerant, a source liquid and a drain liquid, two or more heat exchangers that facilitate an exchange of thermal energy, and a means for transporting the refrigerant.

A hybrid photovoltaic and radiant heating and cooling device is provided, wherein the device comprises a photovoltaic panel; a radiant heating and cooling panel; a first heat-exchanging pipe in direct contact with a back surface of the photovoltaic panel; a second heat-exchanging pipe in direct contact with a back surface of the radiant heating and cooling panel; and a thermal storage tank fluidly connecting the first and the second heat-exchanging pipes, wherein the tank is arranged between the first and second heat-exchanging pipes.

An energy transfer system that includes a tank comprising an outer wall having a circumference. A first fluid pathway surrounds a portion of the circumference of the tank. A second fluid pathway seals the portion of the circumference of the tank and the first fluid pathway from the environment.

The present invention relates to a heat transmitting system for providing a heat medium with a set temperature, characterized in that a heat transmitting system may include: a heat source; a heat source; a plurality of heat storage tanks that stores heat media heated by the heat source respectively; a heat exchanger that is transmitted with heat from the heat media stored in the heat storage tanks; a heat source pump that transmits the heat media transmitted from the heat source to the heat storage tanks; an inlet side-heat source header that is connected with respective inlet ends of the plurality of heat storage tanks; a heat source header valve that is provided between the inlet side-heat source header and the respective inlet ends of the plurality of heat storage tanks; an outlet side-heat source header that is connected with respective outlet ends of plurality of the heat storage tanks; an outlet valve of heat storage tank that is provided to respective outlet ends of plurality of the heat storage tanks; a header outlet valve that is provided between the heat source and the outlet side-heat source header; a heat transmitting line that is connected between the outlet side-heat source header and an inlet end of the heat exchanger, thus transmitting the heat medium to the heat exchanger; and a heat transmitting pump that is provided to one side of a exchanger outlet line connecting the heat transmitting line or the heat exchanger and the inlet side-heat source header.

A control system for controlling a heater includes a power converter, a sensor circuit, and a controller. The power converter supplies an adjustable power to the heater, and the sensor circuit is configured to measure an electrical characteristic of the heater. The controller is coupled to the power converter to control the power to the heater, and is configured to select a state model control, as an operation state of the heater, from among a plurality of defined state model controls. The controller controls the power supplied to the heater based on the operation state of the heater and on the electrical characteristics of the heater.

The present disclosure is directed toward a control system for controlling a heater that includes at least one heating element. The control system includes a power converter operable to supply an adjustable voltage output to the heater, a sensor circuit that measures an electrical characteristic of the heating element of the heater, a reference temperature sensor that measures a reference temperature of a reference at the heater, and a controller. The controller is configured to calculate a primary temperature of a heater element based on the electrical characteristic and determines the voltage output to be applied to the heater based on at least one of the reference temperature and the primary temperature. The controller is configured to operate in at least one of an operation mode and a learn mode, and execute protection protocols when voltage is being supplied to the heater.
