Abstract

Method of operating a refrigeration system of the type having a multiple cylinder compressor (10) or multiple compressor including steps of operating the systems under normal operating conditions, sensing operating conditions, partially unloading the compressor when sensed operating conditions indicate that the ambient temperature or high side pressure exceed a predetermined limit, and continuing the operation of the refrigeration system at reduced capacity, until the sensed conditions indicate normal operating load. Unloading is achieved by flow of high pressure refrigerant passing through a by-pass line 22 to the suction side of the compressor under the control of a pressure switch 25 or temperature control. <IMAGE>
