A refrigeration compressor used in a multi-box refrigeration system is designed with six of its eight cylinders able to be controlled for variable load conditions. If all of the reefer boxes are currently feeding, what percentage of the total number of compressor cylinders will be loaded after start up?

Question

Accepted Answer

Option A: 100%. All reefer boxes feeding indicates maximum cooling load demand; therefore, unloader mechanisms disengage, leaving 100% of the eight compressor cylinders loaded and actively pumping.
