  • Air conditioner and method of controlling the same
    Patent number: 9267720
    Abstract: An air conditioner may include an indoor device and an outdoor device. The outdoor device may include a plurality of compressors, a plurality of bypass tubes respectively connected to the plurality of compressors, and a plurality of bypass valves respectively provided to the bypass tubes. When at least one of the plurality of compressors is stopped during operation of the air conditioner and the plurality of compressors, a bypass valve corresponding to the stopped compressor may be opened to equalize an internal pressure of the stopped compressor to facilitate a re-start of operation of the stopped compressor without adversely affecting overall performance of the air conditioner.

  • Air conditioner and control method thereof
    Patent number: 9151522
    Abstract: An air conditioning system has a controller and a receiver located between an indoor and outdoor units. The receiver serves as an auxiliary reservoir for refrigerant. The controller generates signals to adjust the amount of refrigerant to be stored in this reservoir as a way of adjusting the amount of refrigerant flowing in the system during various modes of operation. By increasing or decreasing the amount of refrigerant in the receiver, the controller may achieve or maintain a desired level of performance and/or efficiency.
