Compared to the air conditioning unit shown in the foregoing, in this embodiment, the throttle valve 63 is disposed on the water inlet pipe 21, and is used for controllably adjusting the throttle area of the water inlet pipe 21, and the throttle area of the water inlet pipe 21 is adjusted by adjusting the opening of the throttle valve 63, so as to adjust the water inlet flow.
In an alternative embodiment, the operation parameters further include a temperature parameter of the electric cabinet, the electric cabinet further includes a temperature sensor 64, and the temperature sensor 64 is used for detecting the temperature parameter when the electric cabinet is operated; the controller 61 is specifically configured to determine a temperature parameter detected by the temperature sensor 64, and adjust the opening of the throttle valve 63 according to the temperature parameter, so as to adjust the flow rate of the water inlet pipe 21.
When the outdoor unit 5 is operated in the non-cooling mode, the throttle valve 63 is controlled to be closed, the solenoid valve 62 is shut off, and the water inlet pipe 21 is closed. In this embodiment, the first water inlet of the water inlet pipe 21 is communicated with the condensate water pipe 3, the first water outlet is connected to the heat exchange module, the electromagnetic valve 62 and the throttle valve 63 are both arranged on the water inlet pipe 21, the cut-off of the water inlet pipe 21 is realized by controlling the cut-off of the electromagnetic valve 62 and the cut-off of the throttle valve 63, the condensate water cannot enter the heat dissipation device 12, and the heat exchange operation of the electric cabinet is stopped.
When the operation state of the outdoor unit 5 is the cooling operation, the electromagnetic valve 62 is controlled to be electrified and opened; when a plurality of outdoor units 5 are operated in the same unit, the controller 61 adjusts the opening degree of the throttle valve 63 based on the temperature parameter detected by the temperature sensor 64.
The specific process of the controller 61 for adjusting the opening of the throttle valve 63 according to the temperature parameter is as follows:
when the temperature parameter detected by the temperature sensor 64 is greater than the set temperature threshold, the opening of the throttle valve 63 on the water inlet pipe 21 of the outdoor unit 5 to which the temperature sensor 64 belongs is controlled to be opened by 80% -100%, specifically, 80%,90% or 100%.
When the temperature parameter detected by the temperature sensor 64 is smaller than the set temperature threshold, the opening of the throttle valve 63 on the water inlet pipe 21 of the outdoor unit 5 to which the temperature sensor 64 belongs is controlled to be opened by 30% -50%, specifically, 30%,40% or 50%.
Thus, with the embodiment shown in fig. 5, when the plurality of outdoor units 5 are connected in parallel, the condensed water is preferentially supplied to the outdoor unit 5 with higher temperature of the electric cabinet by adjusting the opening of the throttle valve 63 when the plurality of outdoor units 5 perform the cooling operation, so that the heat generated by the electric control device can exchange heat with the condensed water with low temperature, and the heat exchange capacity of the water is larger than that of the refrigerant at the same flow rate due to the large specific heat capacity of the water, and the energy of the system is not consumed, thereby realizing the efficient and energy-saving heat dissipation operation.
In an alternative embodiment, the outdoor unit 5 further includes a fan for accelerating the heat dissipation of the heat dissipation device 12. Thus, the controller 61 controls the fan through driving the fan driving module inside the electric cabinet, and helps to accelerate heat dissipation. When the temperature parameter detected by the temperature sensor 64 is greater than the set temperature threshold, the controller 61 drives the fan to operate, thereby assisting in accelerating heat dissipation.
The present invention is not limited to the structure that has been described above and shown in the drawings, and various modifications and changes can be made without departing from the scope thereof. The scope of the invention is limited only by the appended claims.
