METHOD FOR CONTROLLING A COMPRESSOR OF A REFRIGERATION SYSTEM, SAID COMPRESSOR HAVING A MOTOR, AND COMPRESSOR OF A REFRIGERATION SYSTEM

摘要

A method for controlling a compressor of a refrigeration system wherein refrigerant flow through the compressor is controlled by at least one valve, whereby the valve is opened or closed in a cycle of consecutive time intervals of an identical length, so that the valve is either completely closed or completely open during a time interval, whereby a. determining a percentage capacity for the compressor corresponding to the current refrigeration requirement of a refrigeration location, b. determining the open time percentage of the valves over a number of time intervals, c. opening the valve is opened for the following time interval when the ratio of the percentage capacity is greater than that of the open time percentage previously determined, and d. closing the valve for the following time interval when the ratio of the percentage capacity is smaller than that of the open time percentage of the valves previously determined.
