Abstract: A system has: a compressor having a suction port and a discharge port; an ejector having a motive flow inlet, a suction flow inlet, and an outlet; a separator having an inlet, a vapor outlet, and a liquid outlet; a first heat exchanger; an expansion device; and a second heat exchanger. Conduits and valves are positioned to provide alternative operation in: a cooling mode and a heating mode. In the cooling mode, a needle of the ejector is closed. In the heating mode refrigerant passes sequentially from a first section of the second heat exchanger to a second section. In the cooling mode refrigerant passes in parallel through the first section and the second section.

Abstract: A method for controlling a vapour compression system (1) is disclosed. Malfunctioning of a gas bypass valve (8) is registered. An actual opening degree of the gas bypass valve (8) is derived, and a target opening degree of the gas bypass valve (8) is derived, based on one or more control parameters of the vapour compression system (1). The actual opening degree is compared to the target opening degree, and the vapour compression system (1) is controlled based on the comparison, and in order to match a mass flow of gaseous refrigerant through the gas bypass valve (8) to the actual opening degree of the gas bypass valve (8).

Abstract: The present invention provides a refrigerant-containing composition by using a refrigerant that has a refrigerating capacity equivalent to that of widely used R404A, and a low GWP. Specifically, the present invention provides a composition that contains a refrigerant containing difluoromethane (R32), pentafluoroethane (R125), 1,1,1-trifluoroethane (R143a), 2,3,3,3-tetrafluropropene (R1234yf), and 1,1,1,2-tetrafluoroethane (R134a) in specific concentrations.

Abstract: A system for condensing and phase separating a refrigerant fluid includes a condenser inlet header configured to receive a stream of refrigerant vapor. A condenser is in fluid communication with the condenser header and is configured to receive vapor and produce a mixed phase fluid stream. An elongated manifold separator including multiple mixed phase inlets is configured to separate mixed phase fluid received from the condenser. Resulting vapor and liquid streams exit vapor and liquid outlets of the manifold separator.

Abstract: A cooling device includes a number of cooling tubes arranged in parallel such that a first cooling fluid and a second cooling fluid can flow in the cooling tubes. A tank communicates with the cooling tubes to allow the first cooling fluid or the second cooling fluid to flow through the cooling tubes. A diaphragm is located inside the tank to separate the tank into a first space allowing the first cooling fluid to flow therein and a second space allowing the second cooling fluid to flow therein. The diaphragm is coupled to the tank to be rectilinearly movable in a direction of an arrangement of the plurality of cooling tubes.

Abstract: A heat management system disclosed herein is used for a vehicle. The heat management system may include an electric device, a first heat exchanger, a second heat exchanger, a first channel, a second channel, a first pump, a second pump, a first channel valve, a second channel valve, a bypass channel, and a controller. The controller may be configured to, when one of the first pump and the second pump operates abnormally, control the first channel valve and the second channel valve such that the flow of the first heat medium from both of the first channel and the second channel to the first heat exchanger is allowed and activate the other of the first pump and the second pump.
