摘要： A refrigeration cycle system includes a refrigeration cycle apparatus and a refrigerant storage portion. The refrigeration cycle apparatus includes an indoor unit, an outdoor unit, a gas-side connection pipe, and a liquid-side connection pipe. The refrigerant storage portion stores the refrigerant present inside a refrigerant circulation path. The refrigerant storage portion communicates with the refrigerant circulation path through a first storage portion pipe and a second storage portion pipe. The first storage portion pipe causes a first refrigerant pipe of an outdoor refrigerant flow path and the refrigerant storage portion to communicate with each other, or causes the gas-side connection pipe and the refrigerant storage portion to communicate with each other. The second storage portion pipe causes the second refrigerant pipe of the outdoor refrigerant flow path and the refrigerant storage portion to communicate with each other.

摘要： A thermal management system includes a closed-circuit refrigeration system (CCRS) that includes a vapor cycle system (VCS). The VCS includes a receiver configured to store a refrigerant fluid; a liquid separator; a compressor; a condenser; at least one evaporator configured to extract heat from at least one heat load that is in thermal conductive or convective contact with the evaporator; and a thermal energy storage (TES) that stores a phase change material. The thermal management system further includes a liquid pumping system (LPS) that includes the TES, the at least one evaporator, and the liquid separator, with the LPS further including a pump. The VCS is configured to operate one at a time in at least one of three operational modes that are a TES cooling mode, a heat load cooling mode, or a pump-down mode. The LPS is configured to operate in the heat load cooling mode.

摘要： An air-conditioning apparatus can suppress occurrence of disproportionation (an autolytic reaction) when HFO1123 refrigerant or a refrigerant mixture containing HFO1123 is applied. The air-conditioning apparatus includes a controller controlling at least one of an operation frequency of a compressor, an opening degree of an expansion valve, and an air amount of a fan sending air to a heat-source-side heat exchanger so that a temperature and a pressure of the refrigerant discharged from the compressor do not exceed threshold values.

摘要： A heat pump including an integrated system for the management of refrigerant charge is provided. The heat pump includes an indoor line and an outdoor line that are connected to a compressor through a reversing valve. Refrigerant charge is managed by coupling the inactive line to the suction side of the compressor. For example, the heat pump can include an expansion valve to couple the inactive line to the compressor to supplement the flow-rate of refrigerant. The heat pump is operable in a dedicated water heating mode and a space cooling and water heating mode in some embodiments, while other modes of operation are contemplated in other embodiments.

摘要： A refrigerant recovery operation method for use in a refrigerator in which a freezing chamber and a refrigerating chamber are independently cooled is disclosed. The refrigerator and the method for controlling the same guarantee a sufficiently long refrigerant recovery operation time by performing the refrigerant recovery operation not only when the compressor starts operation but also before the compressor stops operation, resulting in implementation of the highest operation efficiency of a refrigerating chamber. The refrigerator guarantees high reliability of the compressor by increasing the refrigerant recovery amount within a predetermined pressure range in which the compressor can operate, and maintains an optimum refrigerant amount by variably controlling the refrigerant recovery operation time according to the outdoor air temperature, resulting in improvement of energy efficiency.

摘要： An air-conditioning apparatus includes an outdoor unit, an indoor unit having an indoor heat exchanger, and a controller for executing a pump down operation. The outdoor unit has an accumulator of a capacity (Va), a compressor, an outdoor heat exchanger, an expansion valve, a large-diameter tube, which are joined by refrigerant pipes. The capacity (Vhi) of the indoor heat exchanger is greater than the capacity (Vho) of the outdoor heat exchanger. The large-diameter tube, which is larger in diameter than the refrigerant pipes, is provided so that the capacity (Vt) of the large-diameter tube satisfies the formula: capacity (Vt)>capacity (Vhi)−capacity (Vho)−capacity (Va).
