Title: Control of refrigerating machine
Inventor: KATSUKI HIKARI
IPC: F04B49/06
Filed: 1988-07-18
Abstract: PURPOSE:To prevent the load from being started and stopped in a short time and from developing related damages and other troubles in a refrigeration cycle by introducing a change-over switch for changing, between the interval from stopping of the compressor to its restarting, the time by which the restarting of the compressor is retarded. CONSTITUTION:In a refrigeration cycle a processor 6 as its primary performance inputs an operation control keyed in by keys 8 and sets an operation mode according to the results of the key scanning. It judges whether a switch 16 is on or not and sets a timer T for a specific time. Then it judges whether the timer T has counted the set time or not. When it finds that the time is up according to the timer T, it inputs the room temperature, compares it with a relevant set value, and, on the basis of this comparison, decides whether or not it should output a signal ON for the compressor; the output of the signal ON causes the compressor to be put in operation. This sequence of judgments makes it possible to extend the time interval between the stopping of a compressor to its restarting beyond a time T. Accordingly, the temperature variation of a load can be restricted to a small range and development of damages or other troubles can be suppressed.
