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 ofthe refrigeration system are optimized, while maintaining the system operation within preset limi...


[ What is claimed is:] [1.] A sealed refrigerated container comprising:a refrigerated box;a refrigeration system for cooling said box, said refrigeration system being provided with a compressor, evaporator, condenser, a throttle valve, an economizer circuit, a suction modulation valve, and an unloader valve for the compressor; anda control for said refrigeration system, said control being programmed to achieve a decrease in the temperature of said box by operation of said compressor, said unloader valve, said suction modulation valve and said economizer ...
