Startup control systems and methods for high ambient conditions
First Claim
1. A refrigeration system, comprising:
- a startup mode control module thatreceives (i) an off time of a compressor of the refrigeration system and (ii) an indication of an ambient temperature during the off time,determines whether the off time of the compressor and the indication of the ambient temperature indicate that the compressor is in a high ambient temperature startup condition based on an amount of time that the ambient temperature is greater than a temperature threshold within the off time, andselects, based on the determination, between a normal startup mode and a high ambient temperature startup mode; and
a compressor control module thatoperates the compressor in the normal startup mode in response to the startup mode control module selecting the normal startup mode,operates the compressor in the high ambient temperature startup mode in response to the startup mode control module selecting the high ambient temperature startup mode, andtransitions from the high ambient temperature startup mode to the normal startup mode after a predetermined period associated with operating in the high ambient temperature startup mode.

Abstract
A refrigeration system includes a startup mode control module that receives at least one parameter associated with operation of a compressor of the refrigeration system, determines whether the at least one parameter indicates that the compressor is in a high ambient temperature startup condition, and selects, based on the determination, between a normal startup mode and a high ambient temperature startup mode. A compressor control module operates the compressor in the normal startup mode in response to the startup mode control module selecting the normal startup mode, operates the compressor in the high ambient temperature startup mode in response to the startup mode control module selecting the high ambient temperature startup mode, and transitions from the high ambient temperature startup mode to the normal startup mode after a predetermined period associated with operating in the high ambient temperature startup mode.

7. A method of operating a refrigeration system, the method comprising:
-
using a startup mode control module, receiving (i) an off time of a compressor of the refrigeration system and (ii) an indication of an ambient temperature during the off time, determining whether the off time of the compressor and the indication of the ambient temperature indicate that the compressor is in a high ambient temperature startup condition based on an amount of time that the ambient temperature is greater than a temperature threshold within the off time, and selecting, based on the determination, between a normal startup mode and a high ambient temperature startup mode; and using a compressor control module, operating the compressor in the normal startup mode in response to selecting the normal startup mode, operating the compressor in the high ambient temperature startup mode in response to selecting the high ambient temperature startup mode, and transitioning from the high ambient temperature startup mode to the normal startup mode after a predetermined period associated with operating in the high ambient temperature startup mode. - View Dependent Claims (8, 9, 10, 11)
