摘要： A pressure increase in a compressor is suppressed. Disclosed is the use of a composition as a refrigerant in a refrigerant circuit (10), in which the composition includes one or more compounds selected from the group consisting of ethylene-based fluoroolefins, 2,3,3,3-tetrafluoropropene (HFO-1234yf), and 1,3,3,3-tetrafluoropropene (HFO-1234ze), and in the refrigerant circuit (10), the total internal volume of a refrigerant pipe (11, 12, 13, 15, 5, 19, 18, 6, 14) and a component (23, 31, 24) that are connected to a compressor (21) is greater than or equal to 0.7 times the internal volume of the compressor.

摘要： A plate-type refrigerant pipe (20) includes: a first plate (21); and a second plate (22) joined to the first plate (21) and forming a refrigerant flow path (F) together with the first plate (21), in which the first plate (21) includes a first connection portion (25A) to which a first refrigerant pipe (100A) is connected to cause the refrigerant flow path (F) and the first refrigerant pipe (100A) to communicate with each other, the second plate (22) includes a second connection portion (25B) to which a second refrigerant pipe (100B) is connected to cause the refrigerant flow path (F) and the second refrigerant pipe (100B) to communicate with each other, the first plate (21) and/or the second plate (22) includes a third connection portion (25C) to which a third refrigerant pipe (100C) is connected to cause the refrigerant flow path (F) and the third refrigerant pipe (100C) to communicate with each other, and the first connection portion (25A) and the second connection portion (25B) overlap each other in a first direction perpendicular to a joining surface (M) of the first plate (21) and the second plate (22).

摘要： A method for operating a heat pump (20; 300) includes operating in a cooling mode wherein heat is absorbed by refrigerant in the indoor heat exchanger (26) and rejected by refrigerant in the outdoor heat exchanger (24). The heat pump switches to operation in a heating mode wherein heat is rejected by refrigerant in the indoor heat exchanger, heat is absorbed by refrigerant in the outdoor heat exchanger, and there is an ejector (60) motive flow and ejector secondary flow. In the heating mode a refrigerant pressure (P H ) or temperature (T L ) is measured and, responsive to the measured refrigerant pressure or temperature, at least one of a fan speed is changed and a needle (132) of the ejector is actuated.
