Abstract
A closed refrigeration system is provided with a mass flow limiting device located upstream of the suction inlet of a compressor. The device limits the mass flow supplied to the compressor during pulldown and startup to prevent overloading the motor or engine driving the compressor but has minimal influence on the refrigeration system under equilibrium conditions since it is designed for the specific system parameters.
