Embodiment Construction

[0019]Reference will now be made in detail to exemplary embodiments of the application, examples of which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals will be used throughout the drawings to refer to the same or like parts.

[0020]FIG. 1 is a diagram that shows an embodiment of a transport refrigeration system. As shown in FIG. 1, transport refrigeration system 100 can include a transport refrigeration unit 10 coupled to an enclosed space within a container 12. The transport refrigeration system 100 may be of the type commonly employed on refrigerated trailers. As shown in FIG. 1, the transport refrigeration unit 10 is configured to maintain a prescribed thermal environment within the container 12 (e.g., cargo in an enclosed volume).

[0021]In FIG. 1, the transport refrigeration unit 10 is connected at one end of the container 12. Alternatively, the transport refrigeration unit 10 can be coupled to a prescribed position on a side or more t...

Abstract

Embodiments of transport refrigeration systems, apparatus, and/or methods for the same can provide exemplary verification for operating characteristics thereof. In one embodiment, a calculated compressor mid stage pressure can be verified using a prescribed relationship to other transport refrigeration system characteristics.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]Reference is made to and this application claims priority from and the benefit of U.S. Provisional Application Ser. No. 61 / 254,280, filed Oct. 23, 2009, and entitled PARAMETER CONTROL IN TRANSPORT REFRIGERATION SYSTEM AND METHODS FOR SAME, which application is incorporated herein in its entirety by reference.TECHNICAL FIELD[0002]This invention relates generally to transport refrigeration systems and methods for same and, more particularly, to methods and apparatus for controlling vapor compression systems.BACKGROUND OF THE INVENTION[0003]A particular difficulty of transporting perishable items is that such items must be maintained within a temperature range to reduce or prevent, depending on the items, spoilage or conversely damage from freezing. A transport refrigeration unit is used to maintain proper temperatures within a transport cargo space. The transport refrigeration unit can be under the direction of a controller. The controller e...
