However, the internal resources of DDC are very limited and cannot be exceeded, and many programs are solidified in DDC. When choosing, it should be compared with the actual application mode according to the inherent program mode of DDC. If the two modes are the same, you can choose. If it is not the same, then this kind of DDC cannot be selected

The invention discloses a variable air volume air-conditioning tail end device and an air volume control method thereof. The device comprises a box body, an air speed sensor and an air volume balance controller, wherein the box body is provided with an air inlet and an air outlet; the air speed sensor comprises a direct-current generator, a blade disc and a plurality of rotor wings; the direct-current generator comprises an armature shaft and is arranged at a middle position of the air outlet along the axial direction of the box body; the blade disc is sleeved on the armature shaft of the direct-current generator; the rotor wings are uniformly connected to the blade disc along the circumferential direction of the blade disc at intervals; and an output end of the direct-current generator is connected with an input end of the air volume balance controller. According to the air volume control method, the temperature serves as main controlled quantity or auxiliary controlled quantity, the air volume serves as another controlled quantity, and PID regulation control is adopted, and therefore, the control of the variable air volume air-conditioning tail end device on the air volume can be simple and direct on the basis that meeting accuracy control is met.
Description
technical field [0001] The invention relates to the field of central air-conditioning terminal air volume control, in particular to a variable air volume air-conditioning terminal device and an air volume control method thereof. Background technique [0002] As we all know, since the energy consumption of central air-conditioning occupies a significant proportion in building energy consumption, people pay more and more attention to energy-saving technology of air-conditioning. Due to the complexity of the central air-conditioning system, the simplified control of the air-conditioning system is more and more sought after by people. [0003] As an energy-saving and efficient air-conditioning system, the VAV air-conditioning system adjusts the air volume sent into the room by changing the air volume terminal device, and adjusts the air volume of the air conditioner main unit (AHU) accordingly to meet the air volume demand of the system. The VAV air conditioning system can auto...
