Abstract
Disclosed is a method for controlling a solenoid valve of an air-conditioner capable of reducing power consumption of an air-conditioner. To this end, in the method for controlling the solenoid valve of the air-conditioner, when at least one compressor of the air-conditioner temporarily stops operating, power is applied to a solenoid valve connected to the compressor for a preset time.
Claims20
A method for controlling a solenoid valve of an air-conditioner comprising:
- a step in which when at least one compressor of the air-conditioner temporarily stops operating, power is applied to a solenoid valve connected to the compressor for a preset time.
A method for controlling a solenoid valve of an air-conditioner comprising:
- measuring a stop time of the compressor when at least one compressor of the air-conditioner temporarily stops operating;
- and
- applying power to a solenoid valve connected to the compressor when the measured stop time passes a preset time.
A method for controlling a solenoid valve of an air-conditioner comprising:
- applying power to solenoid valves connected to compressors of an air-conditioner only for a preset time when the compressors temporarily stop operating, so that power consumption of the solenoid valves connected to the compressors of the air-conditioner is reduced.
A method for controlling a solenoid valve of an air-conditioner comprising:
- a step in which when a stop signal for stopping at least one compressor installed at the air-conditioner is generated, the compressor is stopped;
- and
- a step in which when a stop time of the compressor passes a first preset time, at least one solenoid valve connected to the compressor is opened.
A method for controlling a solenoid valve of an air-conditioner including a first compressor and a second compressor for compressing a refrigerant;
- solenoid valves respectively connected to the first compressor and the second compressor to balance internal pressure of the first compressor and the second pressure, comprising:
- stopping the first compressor or the second compressor when a first stop signal for stopping the first compressor or the second compressor is generated;
- applying power to the solenoid valve connected to the first compressor or the second compressor when a time for which the first compressor or the second compressor stops operating passes a first preset time;
- stopping the first compressor and the second compressor when a second stop signal for simultaneously stopping the first compressor and the second compressor is generated;
- and
- cutting off power applied to the solenoid valves when a time for which the first compressor and the second compressor simultaneously stop operating passes a second preset time.
A method for controlling a solenoid valve of an air-conditioner including a first compressor and a second compressor for compressing a refrigerant;
- and solenoid valves respectively connected to the first compressor and the second compressor to balance internal pressure of the first compressor and the second compressor, comprising:
- stopping the first compressor or the second compressor when a first stop signal for stopping the first compressor or the second compressor is generated;
- applying power to the solenoid valve connected to the first compressor or the second compressor when a time for which the first compressor or the second compressor stops operating passes a first preset time;
- and
- cutting off power applied to the solenoid valves when a time for which the first compressor or the second compressor stops operating passes a second preset time after the power is applied to the solenoid valve connected to the first compressor or the second compressor,
- wherein, the first preset time is a time obtained by subtracting the time required to balance inlet pressure and outlet pressure of the first compressor or the second compressor from a minimum stop time for which the first compressor and the second compressor temporarily stops operating, and the second preset time is a minimum stop time for which the first compressor or the second compressor temporarily stops operating.
