Abstract
A compressor and an air-conditioner having a compressor are provided. The air-conditioner may be operated in a pre-set operation mode according to a detected application voltage or in a pre-set operation mode according to a pre-set time domain. A compressor temperature or an ambient temperature may be detected to operate the air-conditioner in the pre-set operation mode according to the detected application voltage or in the pre-set operation mode according to the pre-set time domain to continuously operate the compressor.
Claims20
An air-conditioner comprising:
- a compressor having a power mode in which the compressor is operated with a maximum compression capacity and a saving mode in which the compressor is operated with a smaller compression capacity than in the power mode;
- a voltage detector that detects an application voltage to determine an operation mode of the compressor;
- a temperature detector that detects an actually measured temperature to determine the operation mode of the compressor;
- and
- a controller that changes the operation mode of the compressor,
- wherein the controller divides a day into a plurality of pre-set time domains and controls the compressor to be operated in the saving mode during at least one pre-set time domain of the plurality of pre-set time domains,
- wherein the controller compares the application voltage detected by the voltage detector and a first and second reference voltage according to an application voltage detection period, and when the application voltage is higher than the first reference voltage, the controller controls the compressor to be operated in the power mode, when the application voltage ranges from the first reference voltage to the second reference voltage, the controller controls the compressor to be operated in the saving mode, and when the application voltage is lower than the second reference voltage, the controller controls the compressor to be stopped, and
- upon determination that the application voltage detected by the voltage detector is higher than the first reference voltage, the controller compares the actually measured temperature detected by the temperature detector and a first and second reference temperature according to an actually measured temperature detection period, and when the actually measured temperature is lower than the first reference temperature, the controller controls the compressor to be operated in the saving mode, when the actually measured temperature is equal to or higher than the first reference temperature but lower than the second reference temperature, the controller controls the compressor to be operated in the power mode, and when the actually measured temperature is equal to or higher than the second reference temperature, the controller controls the compressor to be operated in the saving mode.
