  • Publication number: 20240133588
    Abstract: A storage type heat pump hot water supplying apparatus includes: control circuitry to control a compressor frequency and a pump rotational speed, the compressor frequency being an operating frequency of the compressor, the pump rotational speed being a rotational speed of a water pump. The control circuitry is configured to control, in a heat accumulating operation for accumulating hot water in the hot water storage tank, the pump rotational speed so that the actual hot water discharge temperature becomes equal to a target hot water discharge temperature. The heat accumulating operation includes a first operation and a second operation after the first operation. The compressor frequency in the first operation is higher than the compressor frequency in the second operation. The target hot water discharge temperature in the first operation is lower than the target hot water discharge temperature in the second operation.

  • Publication number: 20230126980
    Abstract: A refrigeration cycle apparatus includes a refrigerant circuit and refrigerant. The refrigerant is a zeotropic mixed refrigerant. At least one of the condenser and the evaporator has a first heat exchange unit located windward and a second heat exchange unit located leeward in a first direction in which air flows. Each of the first heat exchange unit and the second heat exchange unit has an inflow passage and an outflow passage for the refrigerant that are located in a plurality of stages arranged in the second direction crossing the first direction. The refrigerant flows out from the outflow passage of the second heat exchange unit into the inflow passage of the first heat exchange unit. The outflow passage of the second heat exchange unit is located in the same stage as the outflow passage of the first heat exchange unit in the second direction.

  • Publication number: 20230067007
    Abstract: A refrigeration cycle device includes: a refrigerant circuit which circulates a mixed refrigerant containing at least CF3I and HFO1123, the RC including a compressor, an expansion valve, an indoor heat exchanger, an outdoor heat exchanger and a refrigerant reservoir; an injection pipe having a first end at a first height within the refrigerant reservoir and a second end connected to the compressor; and an injection valve included in the injection pipe. The CF3I has the greatest fluid density among refrigerants contained in the mixed refrigerant. The first height is higher than a height at which an end of a refrigerant pipe, other than the injection pipe, is located within the refrigerant reservoir.

  • Publication number: 20230043875
    Abstract: A heat exchanger for an air conditioner for which a zeotropic refrigerant mixture is used is obtained, and the heat exchanger, when used as an evaporator, enables reduction of the amount of required refrigerant without deteriorating the heat transfer performance. The heat exchanger includes: a plurality of fins stacked together at predetermined intervals therebetween; first heat transfer pipes which extend through the plurality of fins, in which a heat medium flows, and which have a plurality of grooves in the inner surface of the pipes; and second heat transfer pipes extending through the plurality of fins, having one end connected to one end of the first heat transfer pipes to form one heat medium flow path, being smaller in pipe diameter than the first heat transfer pipes, and having an inner surface shape providing a pressure loss per unit length smaller than that of the first heat transfer pipes.

  • Publication number: 20220381465
    Abstract: An air conditioner comprises: a refrigerant circuit configured to circulate refrigerant through a compressor, a condenser, an LEV and an evaporator; a first temperature sensor configured to sense the temperature of liquid refrigerant at the inlet port of the evaporator; and a controller configured to control the compressor and the LEV. In a case where a temperature sensed by the first temperature sensor is lower than a frosting reference temperature, the controller increases the opening degree of the LEV and also increases the operating frequency of the compressor as compared with a case where the temperature sensed by the first temperature sensor is higher than the frosting reference temperature.
