  • Publication number: 20200393140
    Abstract: An indoor unit includes: a blow-out port through which air is blown into a space to be air-conditioned; a refrigerant flow path through which flammable refrigerant gas flows; and a refrigerant detection sensor that detects the flammable refrigerant gas that leaks out of the refrigerant flow path. The refrigerant detection sensor faces the space. The refrigerant detection sensor includes a casing. The casing includes a gas intake port that takes in the flammable refrigerant gas. An outside-air-flow-area part of the refrigerant detection sensor is disposed outside of an air flow area through which the air blown through the blow-out port passes. The gas intake port is disposed on the outside-air-flow-area part.

  • Patent number: 10866004
    Abstract: A refrigeration apparatus includes a refrigerant circuit including a utilization unit. The utilization unit includes: a heat exchanger; first and second refrigerant pipes connected to the heat exchanger; and first and second shutoff valves each of whose opening degrees are adjustable and which are respectively provided at the first refrigerant pipe and the second refrigerant pipe. The refrigeration apparatus includes: a refrigerant leakage detector; a refrigerant pressure acquiring part; and a controller configured to adjust the opening degrees of the first shutoff valve and the second shutoff valve. In an alert state where the first shutoff valve and the second shutoff valve are both closed and the refrigerant leakage detector detects the leakage, the controller adjusts the opening degree of at least one of the first and second shutoff valves to open when the pressure of the refrigerant is greater than a predetermined threshold value.
