摘要： A high-efficient central chiller plant system with variable load by phase change material thermal energy storage includes a refrigeration unit and a phase change thermal energy storage. The refrigeration unit operates under the highest COP. If the refrigerating output is higher than the demand of cooling load, the phase change thermal energy storage stores energy by the phase change. Contrarily, if the refrigerating output cannot meet the demand of cooling load, the phase change thermal energy storage releases energy to supply the insufficient cooling load of the refrigeration unit. So that users can set the operation strategy of the refrigeration unit according to the usage statistics, and let the refrigeration unit operate efficiently with the cooperation of the phase change thermal energy storage, thereby effectively improving the energy efficiency of the system operation to save energy. Compared with the existing central chiller system, it saves energy more than 40%-70%.

摘要： A heating, ventilation, air conditioning, and refrigeration (HVACR) system includes a heating fluid circuit, a cooling fluid circuit, and a storage fluid circuit. A thermal system of the HVACR system absorbs energy from the storage fluid circuit and rejects it to the heating fluid circuit. The storage fluid circuit includes thermal storage tanks containing thermal storage material that can provide energy for heating or absorb energy for cooling depending on the state of the thermal storage material. Heating can be provided using the heating fluid circuit and the heat provided by the thermal system. Cooling can be provided using the cooling fluid circuit by absorbing energy from the conditioned space using a cooling fluid and rejecting energy from the cooling fluid to the storage fluid circuit including the thermal storage tanks. The thermal storage tanks can also have heat added to them using an air source heat pump system to provide sufficient storage for heating operations.

摘要： Recovery system for the recovery of thermal energy from waste water from building, which system comprises a heat pump adapted to absorb thermal energy from a non-freeze liquid circulating through the heat pump and arranged to deliver thermal energy to water flowing through the heat pump, a heat exchanger device that is in contact with said waste water, and a pipeline system disposed between the heat pump and the heat exchanger device, and in which non-freeze liquid can circulate. The heat exchanger device is designed so that the non-freeze liquid passes through the heat exchanger device, whereby the non-freeze liquid is able to absorb thermal energy from the waste water. Further, the system comprises a collector tank, and a pipeline system for supplying waste water to the collector tank. The heat exchanger device is disposed in the collector tank, wherein the non-freeze liquid can absorb thermal energy from waste water in the collector tank.

摘要： A system including a heat exchanger with two or more channels is provided. The system includes means for one or more source channels and one or more load channels. The source channels and load channels are enclosed for containing and channeling a heat-bearing fluid through the heat exchanger. The source channels and load channels are integrated as components of complete source circuits and load circuits with the purpose of conveying the heat-bearing fluids between heat/cold loads and the heat exchanger. The system also includes means for providing thermal storage that may be used for sensible heat storage, latent heat storage, or a combination of sensible heat storage and latent heat storage. Within the system there are means for putting the source channels, load channels and thermal storage means in intimate thermal communication with one another for the purpose of exchanging heat in all flow-directions.

摘要： In a split system heat pump cooling and heating system, an auxiliary hot water storage tank is provided as an energy storage bank. Two sets of coils run through this storage tank, a first set carrying hot refrigerant from the heat pump to deposit energy and a second set carrying hot potable water to remove energy. Valve and switch matrixes are operated at the heat pump to provide hot potable water from the energy storage bank during both normal space heating and cooling operations of the heat pump.

A bypass chamber (37) located in the manifold (15) between the flow chamber (35) and the return chamber (36) receives flow water from the flow chamber (35), which has not been drawn off by the heat exchange circuits (8, 9), through a communicating passageway (40). Heat exchange water from the bypass chamber (37) is returned through second outlet ports (55, 56) to others of the heat sources (3, 5, 7).
