Definitions

  • the first valve is controlled to open so that the pipe between the heating device and the heat exchanger of the outdoor machine is connected, so that the heating device participates in Defrosting operation;
  • the first valve is controlled to close so that the heating device and the outdoor unit heat exchanger are The pipe between the two is disconnected, so that the heating device does not participate in the defrosting operation, and the second valve is controlled to open so that the corresponding pipe between the indoor unit and the outdoor unit heat exchanger is connected, and then Enabling the indoor unit to participate in the defrosting operation;
  • the temperature of the heating device includes an inlet water temperature and an outlet water temperature
  • the preset condition includes a defrost temperature threshold
  • the heating device participates in defrosting when the heating device is in the open state, and does not participate in the defrosting when the heating device is in the closed state.
  • the heating device does not participate in defrosting, so that the heating device can be fully utilized for defrosting and will not be frozen, so that the air conditioning system can operate normally.
  • the defrost signal is sent to the detection module 130, and the detection module 130 detects the opening and closing state of the heating device 13 according to the defrost signal. It can be understood that in other embodiments, the defrost signal may be sent to the control module 150 so that the control module 150 controls the detection module 130 to detect the opening and closing state of the heating device 13.
  • the defrost signal can be sent to a terminal that wirelessly communicates with the air-conditioning system 100, and the terminal includes but is not limited to a mobile phone, a tablet computer, a personal computer, a wearable device, other air-conditioning system 100, and the like.
  • Wireless communication can be realized through Bluetooth, WIFI, infrared, mobile network communication (such as 4G, 5G, etc.).
  • the defrost signal may also be generated by the remote controller of the air conditioning system 100 or the aforementioned terminal, and transmitted to the control device 200.
  • control module 150 controls the first valve 17 to close, so that the pipeline between the heating device 13 and the outdoor heat exchanger 15 is disconnected. In this case, it can be avoided that the internal pipes of the heating device 13 are frozen when the heating device 13 participates in the defrosting operation, which affects the subsequent normal operation of the heating device 13.
  • the defrosting operation of the heater 15 prevents the internal pipes of the heating device 13 from freezing.
  • the function of the preset condition is to prevent the heating device 13 from being damaged due to low temperature.
  • the preset conditions can be understood as anti-low temperature conditions or anti-freezing conditions.
  • the heating device 13 when the heating device 13 is in an on state, the heating device 13 will perform heating and have a higher temperature. In this case, the pipes in the heating device 13 are not easily frozen, so that it is convenient for the heating device 13 to participate in the defrosting operation.
  • the heating device 13 When the heating device 13 is in the closed state, the heating device 13 has a lower temperature. In this case, let the heating device 13 not participate in the defrosting operation, so that the pipes in the heating device 13 are not easily frozen to protect the heating device 13 from being affected.
  • the participation of the indoor unit 27 in the defrosting operation means that the control module 150 controls the second valve 29 to open to communicate with the pipeline circuit where the corresponding indoor unit 27 is located, so that the high-temperature refrigerant passes through the indoor unit 27 to the outdoor unit heat exchanger 15.
  • Step S170 When the heating device 13 participates in the defrosting operation and the temperature of the heating device 13 meets the preset condition, control the first valve 17 to close, or end the defrosting operation.
