Abstract
A unit, such as a transport refrigeration unit, may include a plurality of components arranged in multiple stages. At least a portion of the componentsmay be arranged in a serial or parallel manner. A position associated with the plurality of components may be selected to control a load on a power source, such as an engine. For example, a position for each of the components may be selected so as to maximize a delivery of available power from the power source to the unit. In some embodiments, one or more controllersmay measure a parameter associated with the power source and select a position for one or more of the components. In some embodiments, an economized refrigeration cycle may be used. Capacity may be staged from a single stage compression cycle or mode to a multistage compression cycle or mode, with a corresponding increase in capacity via subcooling.
