  • Patent number: 11044836
    Abstract: A refrigerant distribution device includes: a distribution vessel in which a refrigerant liquid flows; a refrigerant inflow pipe connected to a top portion of the distribution vessel and supplied with a refrigerant liquid; a first refrigerant outflow pipe and a second refrigerant outflow pipe connected to a bottom portion of the distribution vessel to discharge the refrigerant liquid; and a float channel switching valve that floats in the refrigerant liquid in the distribution vessel. The flow channel switching valve switches a passage to the first refrigerant outflow pipe when an amount of the refrigerant liquid in one heat receiver does not reach a reference amount of liquid, and cuts off the passage communicating with the first refrigerant outflow pipe and switches the passage to the second refrigerant outflow pipe when the amount of the refrigerant liquid in the one heat receiver reaches the reference amount of liquid.

  • Patent number: 10982874
    Abstract: An air-conditioning apparatus includes a heat pipe, which performs heat exchange. The air-conditioning apparatus provides supply air in a set state (temperature, humidity) through a change in the flow passage of ventilation air and outside air by the selective opening/shutting of dampers, cooling the outside air by spraying mist, and cooling and humidifying the supply air. The cooling temperature and humidity of the supply air is controlled at a ratio of the ventilation air passing through a cooling coil and the ventilation air passing through a bypass passage. Using a bypass passage, ventilation air can directly move to an air supply block without the intervention of the cooling coil within a heat exchange block through which a ventilation air passes.
