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 arranged in a plurality of layers relative to a wheel central axis. One or more parting elements are located between adjacent layers of the plurality of layers, each of parting elements a strip having a strip width less than an axial length of the plurality of layers. 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 heating, ventilation, and air conditioning (HVAC) system includes a vapor compression cycle comprising a heat exchanger and an expansion device arranged in fluid communication with the heat exchanger. A fluid is configured to circulate within the vapor compression cycle in a first direction during a first mode and is configured to circulate within vapor compression cycle in a second, opposite direction during a second mode. A receiver is fluidly coupled to the vapor compression cycle at a connection point. The connection point is positioned between the heat exchanger an the expansion device and the receiver is positioned vertically above the connection point.

Abstract: A refrigerated system includes a heat recovery system defining a heat recovery fluid flow path. The heat recovery system includes an ejector having a primary inlet and a secondary inlet and a first heat exchanger within which heat is transferred between a heat recovery fluid and a secondary fluid. The first heat exchanger is located upstream from the primary inlet of the ejector. A second heat exchanger within which heat is transferred from a heat transfer fluid to the heat recovery fluid is upstream from the secondary inlet of the ejector. At least one recovery heat exchanger is positioned along the heat recovery fluid flow path directly upstream from the first heat exchanger.
