Abstract: A heating and cooling system for use with hot, cold and source fluid circuits. A conduit module couples a heating/cooling module with the fluid circuits. The conduit module includes four three-way valves to communicated fluid from and to the fluid circuits to first and second heat exchangers in the heating/cooling module. The first heat exchanger is used to heat a fluid flow and the second one chills a second fluid flow. The conduit module simultaneously supplies a hot fluid flow to a hot fluid circuit and a cold fluid to a cold fluid circuit. The source fluid is routed by the conduit module. A method of circulating fluid is also disclosed.

Abstract: In a first aspect, a system for heating, cooling, or both heating and cooling a room is disclosed. The system includes a panel with a first, second, and third wall. The second wall is disposed between the first and third walls and separated by a plurality of partitions. The partitions create a first and second row of elongated channels. Each channel in the first row is bounded on two sides by two partitions and on two other sides by the first and second walls. Each channel in the second row is bounded on two sides by two partitions and on two other sides by the second and third walls. The first row of channels is a fluid layer configured to allow heated or cooled fluid to pass through. The fluid layer is in thermal communication with the room. The second row of channels is an insulating vacuum layer, with a reduced pressure that is at least 20% less than atmospheric pressure.

Abstract: The present invention relates to a method for controlling setting of reversible heat pump assemblies (100) of a district thermal energy distribution system (1) in either a heating mode or a cooling mode. The method comprises: determining, at a control server, a first set of the reversible heat pump assemblies (100) to be set in the heating mode during a future time period; determining, at the control server, a second set of the reversible heat pump assemblies (100) to be set in the cooling mode during the future time period, wherein the second set of the reversible heat pump assemblies (100) is separate from the first set of the reversible heat pump assemblies (100); sending, from the control server (200) to the reversible heat pump assemblies (100) of the first set of the reversible heat pump assemblies (100), a respective control message to set the respective reversible heat pump assembly (100) in the heating mode for the future time period; sending, from the control server (200) to the reversible heat pump assemblies (100) of the second set of the reversible heat pump assemblies (100), a respective control message to set the respective reversible heat pump assembly (100) in the cooling mode for the future time period; and setting the respective reversible heat pump assembly (100) in either the heating mode or the cooling mode for the future time period.

Abstract: The present disclosure provides 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.
