摘要： A refrigeration apparatus has a refrigerant circuit formed by connecting a compressor, a condenser, an expansion valve, and an evaporator by a refrigerant pipe. The refrigeration apparatus includes a temperature duration time measuring unit, and a target evaporation temperature calculating unit. The temperature duration time measuring unit measures a high-temperature duration time in a thermo-off state, the high-temperature duration time being time during which the temperature of the interior of a to-be-cooled space is higher than a lowering threshold which is set with reference to a target interior temperature. The target evaporation temperature calculating unit updates the target evaporation temperature by decreasing the target evaporation temperature by a set subtraction coefficient, after the high-temperature duration time becomes greater than or equal to an update reference time.

摘要： Within a warm circuit, a first heat exchanger is in heat exchanging contact with a heat source. A second heat exchanger is in heat exchanging contact with a space to be heated. Within a cold circuit, a third heat exchanger is in heat exchanging contact with a heat sink. A fourth heat exchanger is in contact with an external region. A valve device is to connect the warm circuit with the cold circuit. An actuating device is to switch the fourth heat exchanger into a de-icing mode. The valve device enables mixing of coolant at least partially from a portion of the warm circuit into the cold circuit.

摘要： A refrigeration apparatus uses R32 as refrigerant, and includes a compressor, a condenser, an expansion mechanism, an evaporator, a branch flow channel branching from a main refrigerant channel joining the condenser and the evaporator, a first opening adjustable valve disposed along the branch flow channel, an injection heat exchanger, a first injection channel, a refrigerant storage tank disposed along the main refrigerant channel, and a second injection channel. The injection heat exchanger exchanges heat between refrigerant in the main refrigerant channel and refrigerant passing through the first opening adjustable valve. The first injection channel guides refrigerant that flows in the branch flow channel and that exits from the injection heat exchanger to the compressor or the suction passage. The second injection channel guides a gas component of refrigerant accumulated inside the refrigerant storage tank to the compressor or the suction passage.

摘要： A method is provided for managing a flooded start of a compressor in a vapor compression system. Following an initial bump start, a determination is made as to whether working fluid in a liquid state remains in the sump of the compressor. If working fluid in a liquid state remains in the compressor sump, an additional bump start of the compressor is completed, followed by another determination as to whether working fluid in a liquid state still remains in the compressor sump. If working fluid in a liquid state remains in the compressor sump, another bump start of the compressor is initiated and the sequence repeated until no working fluid in the liquid state remains in the compressor sump. A normal start of the compressor may be initiated after determining no working fluid in the liquid state remains in the compressor sump.

摘要： A heat exchanger comprises a first header (1), a second header (2) spaced apart from the first header (1) by a predetermined distance, flat tubes (3) each of which defines two ends connected to the first and second headers (1, 2), respectively, to communicate the first and second headers (1, 2), fins (4) interposed between adjacent flat tubes (3), and a flow member defining a fluid-flow passage and forming a partition-wall-type heat-exchanging unit with the second header (2). A refrigeration system comprises a compressor, a condenser, a throttle device, and an evaporator that is the heat exchanger. The compressor, condenser, throttle device, and evaporator are connected sequentially, and at least part of refrigerant flowing out of an outlet of the condenser enters into the flow member to exchange heat with a refrigerant flowing out of an outlet of the evaporator.

摘要： A refrigerator includes a compressor compressing a refrigerant, a condenser condensing the refrigerant compressed in the compressor, a refrigerant tube guiding a flow of the refrigerant condensed in the condenser, an expansion device decompressing the refrigerant condensed in the condenser, and an evaporator evaporating the refrigerant decompressed in the expansion device. The evaporator includes an evaporation tube through which the refrigerant decompressed in the expansion device flows, a coupling tube through a refrigerant heat-exchanged with the refrigerant of the evaporator flows, and a heat-exchange fin coupled to the evaporation tube and the coupling tube.

摘要： The heat exchanger includes heat exchange units. Each of the heat exchange units includes a plurality of plate fins and a plurality of flat tubes. The plate fins are arranged spaced apart from one another at intervals so as to allow air to flow therebetween. The flat tubes each have an L shape by bending and inserted through the plate fins so that a refrigerant flows therethrough in a direction in which the plate fins are arranged. The heat exchange units are combined to each other so as to form a rectangular shape. Thus, heat exchange can be efficiently performed by increasing the mounting area.
