Problems solved by technology

When one of the fan components in the air handling unit fails, the whole unit must be shut down at the same time. If the faulty fan causes the motor fan blade to reverse due to the reverse air duct, it will cause damage to the motor itself, power supply system and control system.

Embodiment 1

[0070] Such as figure 1 As shown, an embodiment of the present invention provides a fan assembly, including: at least one fan 100 and at least one damper 200, the damper 200 is arranged at the air inlet of the fan 100 in one-to-one correspondence, and the number of the damper 200 is the same as that of the fan. The number of 100 corresponds, and at least one damper 200 is configured to be suitable for performing an opening and closing action according to an operating state of a corresponding fan 100 of the at least one fan 100 .

[0071] In this embodiment, the fan assembly includes at least one fan 100 and at least one damper 200, wherein each fan 100 and each damper 200 are provided in a one-to-one correspondence, and each fan 100 is provided with a The damper 200 , the opening and closing of the damper 200 can switch whether the air inlet of the fan 100 can take in air, and the damper 200 performs the opening and closing action according to the operation state of the correspo...

Embodiment 2

[0076] Such as figure 1 As shown, another embodiment of the present invention provides a fan assembly, including: at least one fan 100, the same number of dampers 200 as the at least one fan 100, and the dampers 200 are arranged at the air inlet of the fan 100 one by one, The air valve 200 is used for opening and closing according to the operating state of the corresponding fan 100 .

[0077] Wherein, the damper 200 is a gravity one-way damper, which is used to close the damper 200 corresponding to the fan 100 in the shut-down state when the fan 100 is in a stopped state.

[0078] In this embodiment, the air valve 200 can be selected as a gravity one-way air valve.

[0079] Such as figure 2 As shown, when the fan 100 corresponding to the damper 200 starts to operate, the fan 100 drives air to flow, and the flowing air can overcome the gravity of the blades of the damper 200, so that the damper 200 is in an open state, and the flow control can be controlled from the inlet of...

Embodiment 3

[0083] Such as figure 1 As shown, another embodiment of the present invention provides a fan assembly, including: at least one fan 100, dampers 200 and damper drivers having the same number as at least one fan 100, and the dampers 200 are arranged on the fans 100 in one-to-one correspondence. The air inlet, the air valve 200 is used to perform opening and closing actions according to the operating state of the corresponding fan 100 . The damper driver controls the opening and closing action of the damper 200 corresponding to the fan 100 according to the running state of the fan 100 .

[0084] In this embodiment, the fan assembly also includes a damper driver, which is connected to at least one damper 200, and the damper driver can control the opening and closing of the damper 200, realizing the control of the damper 200 according to different situations. The effect of controlling the opening and closing actions of the damper 200 makes the opening and closing state of the damp...

Abstract

The invention provides a draught fan assembly, an air treatment device, a control method and a readable storage medium. The draught fan assembly comprises at least one draught fan and at least one airvalve, the at least one air valve is arranged at an air inlet of the at least one draught fan in a one-to-one correspondence mode, and the at least one air valve is configured to be suitable for executing opening and closing actions according to the operation state of the corresponding draught fan in the at least one draught fan. The air valves execute the opening and closing states according tothe operation states of the corresponding draught fans, the opening and closing states of the air inlets of the draught fans can be switched according to the operation states of the draught fans, thematching degree of the opening and closing states of the air inlets of the draught fans and the operation states of the draught fans is improved, it is avoided that in the related art, after one draught fan in the draught fan assembly breaks down and stops, a whole draught fan assembly needs to be completely stopped is overcome, and it is guaranteed that even if the faulty draught fan exists in the draught fan assembly, the remaining non-faulty draught fans can still normally operate.

Description

technical field [0001] The invention belongs to the technical field of air handlers, and in particular relates to a fan assembly, an air handler, a method for controlling the air handler, and a computer-readable storage medium. Background technique [0002] Air handling units are more and more applied to the ventilation of various public places. When one of the fan components in the air handling unit fails, the whole unit must be shut down at the same time. If the faulty fan causes the motor blade to reverse due to the reverse air duct, it will cause damage to the motor itself, power supply system and control system. Contents of the invention [0003] The present invention aims to solve one of the technical problems existing in the prior art or related art. [0004] To this end, a first aspect of the invention proposes a fan assembly. [0005] A second aspect of the invention proposes an air treatment device. [0006] The third aspect of the present invention proposes a...
