  • Patent number: 7624590
    Abstract: A multi-type air conditioner includes an outdoor unit, one or more indoor units communicating with the outdoor unit, and a liquid-stay preventing device heating and evaporating a liquefied refrigerant so as to prevent the liquefied refrigerant circulating between the indoor unit and the outdoor unit from being accumulated at a low pressure side including the indoor unit. Accordingly, a liquefied refrigerant is not accumulated in an indoor unit and a connection pipe, which are a low pressure side where the pressure is relatively low, but smoothly passes therethrough regardless of a height difference between the indoor unit and the outdoor unit. Therefore, the efficiency of the multi-type air conditioner is improved.
