초록 ▼

A device for controlling a single variable capacity compressor, or multiple variable capacity compressors in either parallel flow or series flow chilling systems, senses temperature and load conditions and uses feedback in conjunction with synchronously and asynchronously timed logic circuitry to automatically control loading, unloading and sequencing of the compressor or compressors in the system in selected increments, thereby yielding a significant reduction in energy consumption as well as increased precision in maintaining a desired chill temperature. Additional circuitry provides for remote manual control as well as safety shut-off and failure indication. Alternative embodiments using solid state logic, including a microprocessor embodiment, are also disclosed.

대표청구항 ▼

A refrigeration system control device for use with two variable capacity compressors comprising, a first timing means for generating a cyclic on and off signal, a first load and unload means adapted for connection to temperature sensing means for automatically generating a signal for varying by a predetermined increment the capacity of the first of said compressors in response to a signal from said temperature sensing means during the on signal of said first timing means, means for generating a second timing signal in response to said signal from said first load and unload means, said second timing signal means having first and second states, a second load and unload means adapted for connection to said temperature sensing means for automatically generating a signal for varying by a predetermined increment the capacity of the second of said compressors in response to a signal from said temperature sensing means during the on signal of said first timing means, means for generating a third timing signal in response to said signal from said second load and unload means, said third timiNg signal means having first and second states, and a first transfer means for automatically activating either said first load and unload means or said second load and unload means during the on signal of said first timing means in response to said second and third timing signals, wherein said first load and unload means is activated when said third timing signal means is in a first predetermined state and said second load and unload means is activated when said second timing signal means is in a first predetermined state.
