Abstract
A method of controlling a reciprocating compressor comprising of starting the reciprocating compressor at a minimum speed in which a frequency of 45-52 Hz is applied, operating the reciprocating compressor at a frequency of 52˜60 Hz and operating the reciprocating compressor at a predetermined rotational speed. Therefore, an optimum amount of lubricating oil is supplied to a sliding part of the reciprocating compressor so that the reliability of parts thereof is secured.
Claims3
A method of controlling a reciprocating compressor operated by a single-phase induction motor, said method comprising the steps of:
- (1) starting the reciprocating compressor at a minimum speed in which a frequency of 45-52 Hz is applied to the single-phase induction motor;
- (2) automatically determining by a programmed microprocessor whether the compressor is operating normally;
- and
- (3) when the compressor is operating normally operating the reciprocating compressor at a predetermined normal rotational speed.
A method of decreasing noise and vibration when starting a reciprocating compressor operated by a single-phase induction motor, said method comprising the steps of:
- (1) starting the compressor by feeding power to the motor at 45-52 Hz;
- (2) automatically determining by a programmed microprocessor whether the compressor has started and is operating normally;
- (3) when the compressor has started and is operating normally, feeding power to the motor at 52-60 Hz;
- (4) automatically determining by programmed microprocessor means whether the compressor is operating normally;
- (5) when the compressor is operating normally, feeding power to the motor at 60 Hz and operating it at a predetermined normal rotational speed.
