  • Patent number: 9651282
    Abstract: An air-conditioning system includes a pump that sends, to an evaporator, a cooling fluid that exchanges heat with a refrigerant at the evaporator, and a first heat exchanger that exchanges heat between ambient air and the cooling fluid that has undergone the heat exchange at the evaporator. A sensible heat exchange cycle is formed by annularly connecting the evaporator, the heat exchanger, and the pump by using a pipe. This system is also includes an air-sending unit that sends air to a second heat exchanger, moisture absorbing-and-desorbing devices that are provided at a passage of the air sent by the air-sending unit and that are disposed in front of and behind the first heat exchanger, and an air-path switching device that reverses a passing direction of air passing through the moisture absorbing-and-desorbing device, the first heat exchanger, and the moisture absorbing-and-desorbing device.

  • Patent number: 9528713
    Abstract: A combined hot water supply and air-conditioning device heat source even in a case where the outside air temperature is high such as in summertime. In heating operation, a combined hot water supply and air-conditioning device controls the capacity of a heat source unit-side heat exchanger equipped to a heat source unit to thereby achieve a balance between the load of the heat source unit, and the total load of indoor units and a hot water supply unit.

  • Patent number: 9389005
    Abstract: In a two-stage compression refrigeration cycle device, a low-pressure side compression mechanism and a high-pressure side compression mechanism are intermittently operated to control such that the temperature of air blown into a freezer approaches a target temperature. Under the control, the high-pressure side compression mechanism is first stopped, and then the low-pressure side compression mechanism is stopped. Further, when a reference time has elapsed after driving the high-pressure side compression mechanism, then the low-pressure side compression mechanism is driven. The refrigeration cycle device can reduce a high-pressure side pressure difference upon driving the high-pressure side compression mechanism, and can also reduce a low-pressure side pressure difference upon driving the low-pressure side compression mechanism.
