Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments:
As shown in fig. 1 and 2, a digital variable air volume device includes a variable air volume box 1, an air inlet 11, an air outlet 3, a fan 4, an adjusting area 2, a temperature sensor 10 and a controller 9, where the air inlet 11 is disposed at one side of the variable air volume box 1, the air outlet 3 is disposed at the other side of the variable air volume box 1, the air inlet 11 and the air outlet 3 are communicated to form a ventilation channel, that is, after the air volume enters the variable air volume box 1 from the air inlet 11, the air volume is discharged from the air outlet 3, and the fan 4 is disposed at the air outlet 3. The fan 4 is preferably a direct current fan 4, and is a direct current fan 4 with continuously adjustable flow.
The air outlet 3 is connected to the adjustment area 2 via a ventilation duct (not shown) so that the air discharged from the air outlet 3 is fed into the adjustment area 2 via the ventilation duct.
The adjusting area 2 is provided with a controller 9, a temperature sensor 10, a return air inlet 13 and an air supply outlet 12. The adjusting area 2 can be set to be multiple to adapt to different application scenes; or a plurality of independent areas are divided in one conditioning area 2, for example, the conditioning area 2 is divided into a first area 5, a second area 6 and a third area 7 in fig. 1, and the first area 5, the second area 6 and the third area 7 can correspond to a first room, a second room and a third room in an actual application scene, and can be adapted to different actual application scenes and requirements. When there are a plurality of (at least two) adjustment areas 2, each adjustment area 2 is connected to the corresponding air outlet 3 one by using an independent air duct and a ventilation passage.
The air supply opening 12 is connected to the ventilation channel through an air duct (not shown) or directly, so that the air supply opening 12 is communicated with the air outlet 3, and the air supply opening 12 supplies air into the regulation area 2, thereby changing the air volume and temperature in the regulation area 2. The air sent into the adjusting area 2 from the air supply opening 12 flows through the adjusting area 2 to become turbid, and is finally discharged through the air return opening 13. Only the air pipe, the air inlet 11 and the air outlet 3 need to be arranged at a user side (namely in the adjusting area 2), and the sizes of the air pipe, the air inlet 11 and the air outlet 3 can be very small, so that the small-sized building air conditioner occupies a very small space in a small-sized building, and is convenient to install and maintain.
Temperature sensor 10 is connected with controller 9, controller 9 with fan 4 electric connection, temperature sensor 10 are used for detecting the temperature in the regulatory region 2 to send the temperature signal who gathers to controller 9, controller 9 controls the operating condition of fan according to the temperature signal who gathers and preset temperature value. When the acquired temperature value is greater than the preset temperature value, the controller 9 controls the fan 4 to increase the working power so as to increase the air output of the air outlet 3, thereby increasing the air output in the adjusting area 2; when the acquired temperature value is smaller than the preset temperature value, the controller 9 controls the fan 4 to reduce the working power so as to reduce the air output of the air outlet 3, thereby reducing the air output in the adjusting area 2; when the collected temperature value is equal to the preset temperature value, the fan 4 continues to work at the current working power. Therefore, the air supply quantity can be automatically adjusted according to the indoor load, the air supply quantity is matched with the indoor load, the comfort level is improved, and the energy-saving effect is obvious. Above can be through controlling fan 4 operating condition according to temperature signal, for example set up comparator or comparison circuit in the controller, take the comparator as an example, the signal of the comparator is the temperature value of gathering, and another way signal of comparator is predetermined temperature value, is connected to fan 4 through the output of comparator, then can be according to the operating condition of fan of output result control of comparator.
the controller 9 is electrically connected with the control panel 8, and the control panel 8 is used for operating the controller 9, so that the working state of the fan 4 can be controlled through the control panel 8, including the opening and closing and the working power of the fan 4.
The control panel 8 comprises a display 81 and operating keys 82, so that the temperature value in the current regulation area 2 can be observed in real time and the control fan 4 can be operated conveniently.
The controller 9 is internally provided with a signal processing circuit 91, the signal processing circuit 91 comprises a PID operation processing circuit 911, the PID operation processing circuit 911 processes a temperature value and a preset temperature value acquired by the temperature sensor 10, and sends a corresponding control signal according to a processed result to control the working state of the fan 4. The operating state of the fan 4 can be controlled more stably by the PID operation processing circuit 911, so that the temperature in the regulation area 2 can be controlled more accurately.
