    • 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. Also, because the refrigerant deficiency is prevented from occurring at a high pressure side, the reliability of the cooling operation is improved, and the liquefied refrigerant accumulated at the low pressure side is introduced into a compressor of the outdoor unit, thereby preventing damage to the compressor.
    • 一种多型空调机,包括室外机,与室外机连通的一个或多个室内机,以及液体制冷剂的加热和蒸发以防止液化的制冷剂在室内机与室外循环的液体防止装置 单元在包括室内单元的低压侧积聚。 因此,不管室内机与室外机之间的高度差如何,液体制冷剂都不会积聚在室内机和压力相对较低的低压侧但顺利通过的连接管。 因此,提高了多型空调的效率。 此外,由于在高压侧抑制制冷剂不足,所以制冷运转的可靠性提高,蓄积在低压侧的液化制冷剂被引入到室外机的压缩机中,从而防止对 压缩机。
