Abstract
A unique method of operating a refrigeration system for rapidly pulling down a refrigerated container temperature includes the use and algorithm for operating several system components. The refrigeration system is preferably provided with a suction modulation valve, a compressor unloader and an economizer circuit. By utilizing each of these components in combination with one another, and at various stages during the pull down capacity and energy efficiency of the refrigeration system are optimized, while maintaining the system operation within preset limits.
