摘要： A heat exchanger includes: a surface with a water-repellent coating. The surface has a surface structure that includes protrusions. Condensed water droplets, each having a droplet diameter that allows a subcooled state to be maintained even under a predetermined freezing condition, combine with one other on the surface and generate an energy. The surface structure uses the energy to remove the combined condensed water droplets from the surface.

摘要： A heat exchanger includes a plurality of flat tubes, a header collecting tube connected to the flat tubes, and fins joined to the flat tubes. The header collecting tube includes a first partition member partitioning an internal space into upper and lower internal spaces, a second partition member partitioning the upper internal space into first and second spaces, an inflow port formed at a bottom part of the first space, an upper communicating passage, a lower communicating passage. A third partition member partitions the lower internal space into an ascension space and an inflow space. A lower communicating port allows refrigerant to pass from the inflow space to the ascension space. The lower communicating port and the refrigerant passages of the flat tubes that are connected to the lower internal space are arranged so as not to overlap each other as viewed along the longitudinal direction of the flat tubes.

摘要： A liquid refrigerant distributor is used for a falling liquid film evaporator. The liquid refrigerant distributor includes a gas-liquid two-phase pipe through which a gas-liquid two-phase refrigerant flows, and a first refrigerant tub including a liquid reservoir section into which the gas-liquid two-phase refrigerant flows from the gas-liquid two-phase pipe. The first refrigerant tub further includes a droplet collector configured to collect droplets contained in a gas refrigerant separated by the liquid reservoir section.

摘要： A refrigeration cycle apparatus uses a sensor that measures temperature of a plurality of refrigerant pipes in a contactless manner. A refrigeration cycle apparatus includes a refrigerant circuit in which a compressor, a heat-source-side heat exchanger, an expansion mechanism, and a use-side heat exchanger are connected in sequence. The refrigeration cycle apparatus includes a temperature detector that detects temperatures at a plurality of points in a contactless manner, and a heat-source-side controller. At least one heat-source-side heat exchanger and the use-side heat exchanger includes a plurality of refrigerant pipes through which refrigerant to be heat-exchanged flows, and a flow rate adjuster. The flow rate adjuster adjusts flow rate of the refrigerant flowing through each of the plurality of refrigerant pipes. The temperature detector detects respective temperatures of the plurality of refrigerant pipes. The heat-source-side controller controls the flow rate adjustment unit based on the temperatures detected by the temperature detector.

摘要： A heat exchanger for an air conditioning device includes flat tubes, a vertically extending header collecting tube connected to the flat tubes, and fins joined to the flat tubes. The header collection tube has a loop structure including partition members, inflow ports, and upper and lower communicating passages. The partition members partition first and second spaces. The flat tubes are connected at the first spaces. The inflow ports are located in lower parts of the first spaces. The upper communicating passages communicate the upper parts of the first and second spaces to guide refrigerant from the first spaces into the second spaces. The lower communicating passages communicate the lower parts of the first and second spaces to guide refrigerant from the second spaces towards spaces above the inflow ports in the first spaces to return the refrigerant from the second spaces to the first spaces.

摘要： A refrigeration cycle apparatus efficiently performs a cooling operation and a heating operation using a low-pressure refrigerant and a high-pressure refrigerant. A refrigeration cycle apparatus using a first refrigerant having 1 MPa or less at 30° C. and a second refrigerant having 1.5 MPa or more at 30° C. performs a heating operation by performing a two-stage refrigeration cycle including a use-side refrigeration cycle using the first refrigerant and a heat-source-side refrigeration cycle using the second refrigerant, and performs a cooling operation by performing a single-stage refrigeration cycle using the first refrigerant.

摘要： A shell and plate heat exchanger includes a shell forming an internal space, and a plate stack housed in the internal space. A plurality of refrigerant channels communicate with the internal space, and a plurality of heating medium channels are blocked from the internal space. Each of the refrigerant channels is adjacent to an associated one of the heating medium channels with heat transfer plate interposed between. Each of the heat transfer plates includes a first communication hole that communicates with the heating medium channels to introduce the heating medium, a second communication hole formed below the first communication hole that communicates with the heating medium channels to emit the heating medium, and a guide crossing between the first and second communication holes to guide the heating medium that has flowed into the heating medium channels from the first communication hole toward side portions of the heat transfer plate.
