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%. When all refrigerated boxes are actively calling for cooling and feeding refrigerant, the suction pressure remains high, keeping all controllable cylinders active resulting in 100% cylinder loading upon startup.
