Abstract (en)
[origin: WO9932838A1] To regulate a cooling system operation, a value from an energy value sensor such as a thermostat (28) or pressure trol (40) is sensed and, if the value warrants a call for compressor operation, the call is made. The last compressor off-call-time (T0-T2) is stored in memory (61). If the off-call-time (T0-T2) is less than a short-cycle interval (T2-T3), the compressor (41) is delayed to allow substantial compressor pressure equalization. Compressor operation is delayed further for a percentage of the off-call-time (T0-T2). Compressor on-time (T1-T2) is also measured and, if on for a substantial interval, the compressor (4) is given a short rest (T3-T4). Improved efficiency results.
