A system and method for conditioning air within an air handling system of a building is provided. The building has a hot water source and a cold water source. The conditioning system includes at least one heating-cooling unit connected to the air handling system, a primary water storage device, at least one heat pump, and a controller. The heating-cooling unit, which includes at least one chilled beam, is operable to transfer heat into or out of air passing within the air handling system of the building. The primary water storage device is operable to store a volume of water within a predetermined temperature range. The primary water storage device is in communication with the hot water source and the cold water source. The heat pump is connected to the primary water storage device and the chilled beam. The controller is adapted to selectively drive the heat pump to transfer heat between the primary water storage device and the chilled beam. The controller is also adapted to selectively control the system to transfer heat into or out of the primary water storage device to maintain the water within the primary storage device within the predetermined temperature range.

Hot water heating systems and methods for heating the atmosphere within a predefined area. The systems include a hybrid water heating and storage apparatus configured to heat and store water including a heat pump and an electric heating tank. The systems include a recirculating pump configured to selectively draw a hot output flow of heated water from the electric heating tank, pass the heated water through a heat exchange fixture to heat the atmosphere within a predefined area, and direct the water back to the electric heating tank from the heat exchange fixture as a cold input flow. The systems further include thermostat electrically coupled to the recirculating pump and positioned within the predefined area configured to sense the temperature of the atmosphere within the first predefined area and selective operate of the recirculating pump based on a sensed temperature and a user selected temperature.

Example embodiment relate to a device for heating room air and a liquid. Room air enters and exits the device via an air inlet and an air outlet, and the liquid enters and exits the device via a liquid inlet and a liquid outlet. The heat transfer device transfers the thermal energy produced by an energy unit to the liquid in an interaction area of a medium line. A conveying device moves liquid and/or air between a medium container and the medium line. A control unit controls the conveying device. In case the device is intended to heat only room air in an air mode, the control unit, in a preparation step, controls the conveying device such that the conveying device moves air from an air cushion in the medium container through the medium line.

A dual function water heater and air-conditioning unit including air-conditioner and water heater subassemblies. In the operational cycle illustrated, the unit heats the water in a geyser and operates an air-conditioner in cooling mode. The geyser heat exchanger acts as a condenser in which the refrigerant transitions from a vapor phase to a liquid phase. The liquid refrigerant is conveyed to an interior unit expansion valve where the liquid refrigerant is flash evaporated and conveyed to the interior unit heat exchanger operating as an evaporator, in which adiabatic cooling of the refrigerant causes extraction of heat from air flowing over the interior unit heat exchanger tubes. The extracted heat is transferred to the refrigerant, causing evaporation of the liquid refrigerant to a gaseous refrigerant, which is directed, from the internal unit heat exchanger to the compressor, for repetition of the cycle.

An air heating apparatus includes an expansion tank storing water, a water heating device that receives heat from combustion gas generated by a combustion reaction and heats the water, a heating heat exchanger that receives the water heated by the water heating device and conducts heat exchange between air to be released for heating and the water, a fan that supplies the air to the heating heat exchanger, a case in which the water heating device, the expansion tank, the heating heat exchanger, and the fan are disposed, and a panel assembly electrically connected with at least one of the expansion tank, the water heating device, the heating heat exchanger, or the fan. The panel assembly includes a panel device at least partially exposed outside the case, and a position of the panel device is fixed in a state in which the panel device is rotated relative to the case.
