Power savings apparatus for transport refrigeration system, transport refrigeration unit, and methods for same
First Claim
1. A transport refrigeration unit for regulating the temperature of an enclosed volume, the transport refrigeration unit comprising:
- a refrigeration module operatively coupled to said enclosed volume, said refrigeration module including;
a supply port to output air to said enclosed volume at a supply temperature;
a return port to return air from said enclosed volume to the refrigeration module at a return temperature;
at least one component configured to operate in a first cooling mode and an economy mode; and
a controller configured to change a length of a subsequent operating interval for said at least one component in said economy mode based on at least one previous operating interval of said at least one component in said economy mode.

Abstract
Embodiments of systems, apparatus, and/or methods can control conditions such as temperature within a container of a transport refrigeration system. Embodiments can include a controller for controlling the transport refrigeration system to reduce power consumption. Embodiments of systems, apparatus, and/or methods for operating the same can control cycling of a transport refrigeration unit to conserve power where a subsequent cycle time in a power savings mode is based on at least one previous cycle time. In addition, components can be enabled based on monitored conditions to reduce power consumption.

17. A computer program product comprising a non-transitory computer usable storage medium to store a computer readable program that, when executed on a computer, configures the computer to perform operations to operate a transport refrigeration unit, the operations comprising:
-
operate the transport refrigeration unit in a power savings mode for a first period; switch the transport refrigeration unit to operate in a first mode; and operate the transport refrigeration unit in the power saving mode for a second period in the power savings mode having a different length than the first period in the power savings mode, wherein the length of the second period is a function of the first period. - View Dependent Claims (18)

19. A method of operating a transport refrigeration unit, comprising:
-
operating the transport refrigeration unit in a power savings mode for a first cycle; switching the transport refrigeration unit to operate in a first mode; and operating the transport refrigeration unit in the power saving mode for a second cycle having a different length than the first cycle in the power savings mode, wherein the length of the second cycle is based on a length of the first cycle.
