Abstract: A heat recovery wheel for a heat exchanger includes a wheel rim defining an outer perimeter of the heat recovery wheel, and a plurality of wheel passages located between the wheel rim and the wheel axis. The plurality of wheel passages are at least partially defined by one or more passage fins. At least a portion of a passage fin of the plurality of passage fins extends non-parallel to the wheel axis between a first wheel end and a second wheel end. The plurality of wheel passages are configured for flow of a first airflow and a second airflow therethrough for thermal energy exchange between the first airflow and the second airflow.

Abstract: A heat recovery wheel for a heat exchanger includes a wheel rim defining an outer perimeter of the heat recovery wheel, and a plurality of wheel passages located between the wheel rim and the wheel axis. The plurality of wheel passages are arranged in a plurality of radial layers relative to a wheel central axis. Each layer is defined by a first shaped material having a first cross-sectional shape and a second shaped material assembled to the first shaped material, the second shaped material having a second cross-sectional shape. Radially adjacent layers of the plurality of layers are secured directly to one another, and the plurality of wheel passages are configured for flow of a first airflow and a second airflow therethrough for thermal energy exchange between the first airflow and the second airflow.

Abstract: The present disclosure relates to heat exchangers and heat exchange systems such heat exchangers. The heat exchangers include a shell having an inlet and an outlet and heat exchange tube bundles arranged therein. The shell includes a first region communicating with the inlet configured to accommodate the heat exchange tube bundles and a refrigerant input from the inlet. The refrigerant performs heat exchange with a fluid in the heat exchange tube bundles. A second region is arranged between the first region and the outlet and communicates with the first region and the outlet. A heating device is disposed in the second region. Embodiments may optimize spatial layout of the heat exchanger tube bundles, effectively improving the utilization of shell space of the heat exchanger the heat transfer efficiency of the heat exchanger at the same material cost, and enhance the overall performance, safety and reliability of the system.

Abstract: A thermally enhanced heating system and a method for thermally enhancing a HVAC system are provided. The thermally enhanced heating system preferably includes an outdoor HVAC unit and an indoor HVAC unit. The indoor HVAC unit includes a first heat exchanger for transferring heat from a refrigerant, a second heat exchanger for transferring heat from a fuel source, and a third heat exchanger for transferring heat to the refrigerant. The outdoor HVAC unit includes an outdoor heat exchanger for transferring heat from an outdoor air to the refrigerant, a pump configured to circulate the refrigerant, and an ejector configured to combine the refrigerant from the outdoor heat exchanger and the third heat exchanger. Preferably the outdoor HVAC unit is operated to circulate the refrigerant through a first refrigerant circuit and a second refrigerant circuit, and combine refrigerant in the first refrigerant circuit and the second refrigerant circuit.
