Method for sequentially operating refrigeration system with multiple evaporators.

摘要

A method and apparatus for sequentially operating a refrigeration system with multiple evaporators is provided in which only one evaporator is operated at a time and is run until a detected demand for cooling associated with that evaporator is satisfied, or until a predetermined time period has elapsed which corresponds to the normal run time for that evaporator. If the run time expires prior to the demand for cooling being satisfied, and if demand for cooling by another one of the evaporators is present, then operation of the first evaporator is terminated and the other evaporator is operated. Efficiency enhancements are provided such as prematurely initiating operation of a second evaporator at the conclusion of operation of a first evaporator if it appears that a demand for cooling by the second evaporator will occur within a short period of time following termination of operation of the first evaporator. <IMAGE>
