摘要: An indoor unit includes an air-sending fan, an air inlet through which air of an indoor space is sucked in, and an air outlet located above the air inlet and through which the air sucked in through the air inlet is blown out to the indoor space. A control unit activates the air-sending fan when leakage of the refrigerant is detected. When M [kg] represents an amount of charge of the refrigerant in a refrigeration cycle, LFL [kg/m3] represents a lower flammable limit of the refrigerant, A [m2] represents a floor area of the indoor space, and Ho [m] represents a height of the air outlet above a floor surface of the indoor space, the amount of charge M, the lower flammable limit LFL, the floor area A, and the height Ho satisfy a relationship of M

摘要: A refrigeration cycle apparatus includes a refrigerant circuit in which refrigerant circulates, a temperature sensor provided at a position on the refrigerant circuit, the position being adjacent to a brazed portion or adjacent to a joint portion in which refrigerant pipes are joined to each other, and a controller configured to determine whether or not the refrigerant has leaked based on a detected temperature detected by the temperature sensor. The temperature sensor is covered with a heat insulating material together with the brazed portion or the joint portion.

摘要: The inside of a casing constituting an indoor unit of an air-conditioning apparatus is laterally divided by an air passage partition so that an air passage chamber housing an indoor fan and an indoor heat exchanger is defined close to a casing side panel. A space in the casing close to the casing side panel is further vertically divided by a partition having through holes and so that a pipe connection chamber housing parts of the extension pipes, flare joints, and indoor pipes is defined in an upper portion and a pipe draw-out chamber in which the extension pipes are arranged is defined in a lower portion. Gaps between outer peripheries of the extension pipes and inner peripheries of the through holes are filled with insulations.

摘要: A refrigeration cycle device uses a refrigerant having a higher concentration than air under atmospheric pressure, and is capable of preventing a region having a certain refrigerant concentration or higher from being formed even if the refrigerant leaks in a casing of the refrigeration cycle device in a nonenergized state. The refrigeration cycle device includes: a casing having a first opening and a second opening, one of which is an inlet and the other of which is an outlet, and having therein an air course providing communication between the first opening and the second opening; and a refrigerant circuit provided in the air course in the casing and filled with a refrigerant having a higher concentration than air under atmospheric pressure, the casing having a third opening providing communication between the air course and outside of the casing.
