Abstract: A compensator for an indoor unit of a reversible heat pump is disclosed. The compensator comprises a conduit of a predefined profile having a first end, and a second end. The first end of the conduit is adapted to be fluidically coupled to a thermal expansion device and a primary header of the indoor unit, such that the conduit remains above a connection point between the conduit, the thermal expansion device, and the primary header. The compensator is configured outside the indoor unit in one or more configurations. The compensator stores excess charge created between heating and cooling modes of the heat pump.

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.

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.
