  • Outdoor unit of air conditioner and method for controlling the same
    Patent number: 9435548
    Abstract: An outdoor unit for an air conditioning system includes a tank to store defrosting liquid, a nozzle to apply defrosting liquid from the tank to a heat exchanger, a valve to control flow of the defrosting liquid between the tank and nozzle, and a controller to control the valve based on a temperature of the heat exchanger and a number of times the valve has been set to an open state during a heating mode of the air conditioning system.
    Type: Grant

  • Hot water supply apparatus associated with heat pump
    Patent number: 9234675
    Abstract: A hot water supply apparatus associated with a heat pump is provided. The hot water supply apparatus may employ a cascade heat pump including a two-stage cycle to perform a hot water supply operation. Refrigerants flowing through a heat side heat exchanger and a usage side heat exchanger may be heat-exchanged with water. Thus, the hot water supply operation may be continuously performed, without a defrosting operation, and hot water supply performance and heating performance may be improved.
