    摘要： A refrigeration cycle device according to the present invention performs a heating operation and a defrosting operation. A refrigerant circulates in opposite directions in the defrosting operation and the heating operation. The refrigeration cycle device includes a compressor, a first heat exchanger and a second heat exchanger, a decompressor, and a flow path switch. The flow path switch switches directions of circulation of the refrigerant. In the heating operation, the refrigerant circulates in the order of the compressor, the first heat exchanger, the decompressor, and the second heat exchanger. In the defrosting operation, the refrigerant circulates in the order of the compressor, the second heat exchanger, the decompressor, and the first heat exchanger. The defrosting operation includes a first mode and a second mode. The opening of the decompressor is greater in the first mode than in the heating operation. The opening of the decompressor is less in the second mode than in the first mode.

    摘要： The inside of a casing 110 constituting an indoor unit 101 of an air-conditioning apparatus 100 is laterally divided by an air passage partition 20 so that an air passage chamber 21 housing an indoor fan 7f and an indoor heat exchanger 7 is defined close to a casing side panel 117. A space in the casing 110 close to the casing side panel 118 is further vertically divided by a partition 30 having through holes 31 a and 31 b so that a pipe connection chamber 22 housing parts of the extension pipes 10a and 10b, flare joints 15a and 15b, and indoor pipes 9a and 9b is defined in an upper portion and a pipe draw-out chamber 23 in which the extension pipes 10a and 10b are arranged is defined in a lower portion. Gaps between outer peripheries of the extension pipes 10a and 10b and inner peripheries of the through holes 31 a and 31 b are filled with insulations 19a and 19b.

    摘要： A combined system for heating (1) a main water circuit (30) comprising a condensing boiler (20) and a heat pump (11, 12, 13, 14, 16). The boiler (20) has a combustion fumes outlet (23), the heat pump (11, 12, 13, 14, 16) comprises a refrigerant circuit (11) in which a refrigerant fluid flows and a first heat exchanger (12) crossed by the circuit (11) in which the refrigerant fluid receives heat passing from a liquid state to a gaseous state. The combined heating system (1) comprises a duct (40) extending between the fumes outlet (23) of the boiler (20) and said first heat exchanger (12) so as to carry the fumes coming from the fumes outlet (23) at the first heat exchanger (12).
