Definitions

  • An object of the invention is to overcome the above problem, and is to provide a refrigeration cycle apparatus that can continue the operation regardless of failure of any of multiple refrigerant circuits.
  • a refrigeration cycle apparatus according to an embodiment of the invention is provided in claim 1.
  • the refrigerant flow switching devices 4a, 4b, 4c, and 4d switch the flow of refrigerant upon the switching between a cooling mode and a heating mode.
  • elements having an identical configuration may be collectively referred to as, in this case, "refrigerant flow switching devices 4.”
  • the air-side heat exchangers 5a, 5b, 5c, and 5d function as condensers in the cooling mode and as evaporators in the heating mode.
  • the air-side heat exchangers 5a, 5b, 5c, and 5d allow the refrigerant and the air supplied by the air-side heat exchanger fans 6a, 6b, 6c, and 6d to exchange heat with each other, for example.
  • the main expansion valves 7a, 7b, 7c, and 7d serve as pressure reducing valves or expansion valves, and decompress to expand the refrigerant.
  • a typical example of the main expansion valves 7a, 7b, 7c, and 7d is an electronic expansion valve having a controllable opening degree.
  • the main expansion valves 7a, 7b, 7c, and 7d having an identical configuration may be collectively referred to as "main expansion valves 7."
  • the water-side heat exchangers 8a, 8b, 8c, and 8d allow the refrigerant flowing in the respective refrigeration cycles 2 and the water (heat medium) to exchange heat with each other.
  • the water inlets of the water-side heat exchanger 8a and the water-side heat exchanger 8b are connected in parallel with a water pipe 9a.
  • the water outlets of the water-side heat exchanger 8c and the water-side heat exchanger 8d are connected in parallel with a water pipe 9b.
  • the water outlet of the water-side heat exchanger 8a and the water inlet of the water-side heat exchanger 8c are connected in series with a water pipe 9c.
  • the water outlet of the water-side heat exchanger 8b and the water inlet of the water-side heat exchanger 8d are connected in series with a water pipe 9d.
  • the water-side heat exchangers 8a, 8b, 8c, and 8d correspond to the "heat medium-side heat exchangers" in the present invention.
  • the water pipes 9c and 9d correspond to the "first heat medium passage” and "second heat medium passage,” respectively, in the present invention.
  • elements having an same configuration may be collectively referred to as "water-side heat exchangers 8.”
  • a high humidity of the air and a low temperature equal to or lower than 0 degrees C at the heat transferring surfaces of the air-side heat exchangers 5 cause the water vapor in the air to condense and freeze and thus generate frost on the heat transferring surfaces.
  • the frost on the air-side heat exchangers 5 increases the wind resistance thereof, resulting in insufficient performance of the air-side heat exchangers 5. This problem requires a defrosting operation for melting the frost on the air-side heat exchangers 5, which needs a heat source for melting the frost.
  • the heat source controller 11 determines whether any one of the four refrigeration cycles 2a, 2b, 2c, and 2d is to conduct the defrosting operation. If any one of the refrigeration cycles is to conduct the defrosting operation; then the process goes to Step S5; otherwise the process goes to Step S1.
  • the heat source controller 11 conducts the defrosting operation of the refrigeration cycle 2 being a target. The process then goes to Step S1.
  • the water-side heat exchangers 8 according to Embodiment 2 are individually disposed in the respective refrigeration cycles 2a, 2b, 2c, and 2d. Even if any water-side heat exchanger 8 is punctured by freezing of water, for example, the other refrigeration cycles 2 can continue the operation for the moment because of the independent water-side heat exchangers 8.
  • the water from the refrigeration cycle 2a and the water from the refrigeration cycle 2b join each other in the water pipe 9g.
  • This configuration can suppress a decrease in the temperature of the water entering the refrigeration cycle 2c and the refrigeration cycle 2d and thus can stabilize the heating operations of the refrigeration cycle 2c and the refrigeration cycle 2d.
  • Fig. 5 is a schematic diagram illustrating the configuration of the refrigeration cycle apparatus according to Embodiment 3 of the invention.
  • the basic configuration of the heat source device 1 according to Embodiment 4 is same as that of the heat source device 1 according to Embodiment 1.
  • the following description of Embodiment 3 thus focuses on the difference from Embodiment 1, i.e., the configuration of the water pipes 9 and additional valves 12 in the water pipes 9.
  • the water inlets of the water-side heat exchanger 8a and the water-side heat exchanger 8b are connected in parallel with a water pipe 9m.
  • the water outlets of the water-side heat exchanger 8c and the water-side heat exchanger 8d are connected in parallel with a water pipe 9n.
  • the water outlet of the water-side heat exchanger 8a and the water inlet of the water-side heat exchanger 8c are connected in series with a water pipe 9o.
  • the water outlet of the water-side heat exchanger 8b and the water inlet of the water-side heat exchanger 8d are connected in series with a water pipe 9p.
  • This heat source controller 11 can vary the combination of the water pipes 9 in which water flows by switching the valves 12 depending on the operational mode of the heat source device 1.
  • the heat source controller 11 can also vary the range of the flow rate of water in the heat source device 1.
  • the heat source controller 11 can vary the combination of the water pipes 9 in which water flows and also vary the range of the flow rate of water in the heat source device 1 by switching the valves 12. That is, the range of the flow rate of water in the heat source device 1 can be varied by on-site operations of the heat source controller 11 to transmit signals to the valves 12 for switching the valves 12, without reconstruction of the water pipes 9.
