  • Patent number: 10724766
    Abstract: A refrigeration cycle apparatus includes a refrigerant circuit through which refrigerant is circulated, a heat exchanger unit that accommodates a heat exchanger of the refrigerant circuit and a fan, a temperature sensor disposed in an area of the refrigerant circuit adjacent to a brazed connection or in an area of the refrigerant circuit adjacent to a joint between refrigerant pipes, and a controller configured to determine the presence of refrigerant leakage based on a temperature detected by the temperature sensor. The temperature sensor is covered by a heat insulation material together with the brazed connection or the joint. The controller activates the fan upon determining that refrigerant leakage is present, and is triggered to deactivate the fan in response to the time variation of the temperature detected by the temperature sensor becoming positive.

  • Publication number: 20200208860
    Abstract: In an air-conditioning apparatus, even if gas other than refrigerant flows into an indoor unit of the air-conditioning apparatus through an air inlet of the indoor unit, a sensor does not make erroneous detection, and if refrigerant leakage occurs, the sensor reliably detect the refrigerant leakage. The air-conditioning apparatus uses refrigerant having a higher density than that of air, and includes a housing, an air inlet provided in a front surface of the housing to allow air in a room to flow into the housing, a heat exchanger that transfers heat between the refrigerant and the air that flows into the housing through the air inlet, an air outlet that allows the air subjected to heat exchange at the heat exchanger to be blown from the housing, a fan provided in an air passage extending from the air inlet to the air outlet, and a sensor that detects leakage of the refrigerant. The heat exchanger is provided above the fan, and the sensor is provided below the fan.
