摘要： A heat exchange unit includes a heat exchanger including a plurality of heat transfer tubes and a plurality of refrigerant distributors. Each of the plurality of refrigerant distributors includes an inlet pipe through which refrigerant flows into the refrigerant distributor and a plurality of distribution pipes through which the refrigerant flows out of the refrigerant distributor. Each of the plurality of distribution pipes is connected to a corresponding one of the plurality of heat transfer tubes. The inlet pipe of the refrigerant distributor having a relatively low average value of levels of the plurality of distribution pipes connected to the plurality of heat transfer tubes has a smaller inside diameter than the inlet pipe of the refrigerant distributor having a relatively high average value of levels of the plurality of distribution pipes connected to the plurality of heat transfer tubes. In each of the plurality of refrigerant distributors, the distribution pipe that is included in the plurality of distribution pipes and that is connected at a relatively low level to the heat transfer tube has a smaller inside diameter than the distribution pipe that is included in the plurality of distribution pipes and that is connected at a relatively high level to the heat transfer tube.

摘要： A method for controlling a vapour compression system (1) is disclosed, the vapour compression system (1) comprising at least one expansion device (8) and at least one evaporator (9). For each expansion device (8), an opening degree of the expansion device (8) is obtained, and a representative opening degree, ODrep, is identified based on the obtained opening degree(s) of the expansion device(s) (8). The representative opening degree could be a maximum opening degree, ODmax, being the largest among the obtained opening degrees. The representative opening degree, ODrep, is compared to a predefined target opening degree, ODtarget, and a minimum setpoint value, SPrec, for a pressure prevailing inside a receiver (7), is calculated or adjusted, based on the comparison. The vapour compression system (1) is controlled to obtain a pressure inside the receiver (7) which is equal to or higher than the calculated or adjusted minimum setpoint value, SPrec.

摘要： Provided is an air-conditioning apparatus including a switching valve and a bypass circuit. The switching valve is provided between an expansion valve and an outdoor heat exchanger. The bypass circuit has a first end connected to a refrigerant pipe connecting a compressor and an indoor heat exchanger to each other, and a second end connected to the switching valve. During a heating operation, the air-conditioning apparatus causes a rotating member of the switching valve to rotate to sequentially connect, to the bypass circuit, flow passages of the outdoor heat exchanger connected in parallel, to thereby defrost the outdoor heat exchanger while performing the heating operation.
