Abstract
The utility model discloses a new trend multizone CO2 controlling means, it is including the new trend unit that intelligent control ware, new fan and every room set up, interim the new trend unit includes power -driven air valve executor and CO2 sensor, and the new trend is connected through the fresh wind tube to the air inlet end of new fan, and the air outlet of new fan passes through blast pipe and every room UNICOM, and the air outlet in every room sets up power -driven air valve executor and CO2 sensor, and CO2 sensor is connected with the intelligent control ware respectively with new fan. The utility model discloses an independent domain arrangement CO2 sensor is accurate to judge whether certain regional CO2 concentration exceeds standard and according to the new amount of wind of quantity automatically regulated that exceeds standard. CO2 concentration reaches the hop count that new fan delivery was progressively reduced to demand concentration in the air. At the blast pipe installation pressure controller of new fan, segmentation constant voltage control can prevent that the tuber pipe from uttering long and high -pitched sounds.
Description
Technical field
The utility model relates to a kind of new wind multizone CO
2control device, belongs to the technical field that new general mood body controls.
Background technology
CO
2density is large compared with air, works as CO
2time few to human body without harm, but can affect the breathing of people when it exceedes a certain amount of, reason is that the carbonate concentration in blood increases, and acidly strengthens, and produces acid poisoning.CO in air
2volume fraction when being 1%, feel unhappy, dizzy, palpitaition; Come over dizzy during 4%-5%.Make people's obnubilation when more than 6%, breathe stopping gradually so that death.
Therefore the CO in necessary control room
2concentration, avoids producing harm to human body.
Existing CO
2control CO just
2sensor is arranged on total backwind tube or a certain room, and measuring points placement is not enough, and measuring and adjusting is inaccurate.Its control logic and method can not meet in actual use CO
2content control effectively.
Utility model content
The problem that the utility model solves is that the defect existed for prior art provides a kind of new wind multizone CO
2control device.
The utility model object is achieved through the following technical solutions:
A kind of new wind multizone CO
2control device, comprise the new wind unit that intelligent controller, new blower fan and each room are arranged, interim described new wind unit comprises electric air valve actuator and CO
2sensor, the air intake of new blower fan connects new wind by fresh wind tube, and the air outlet of new blower fan is by ajutage and each room UNICOM, and the air outlet in each room arranges electric air valve actuator and CO
2sensor, CO
2sensor is connected with intelligent controller respectively with new blower fan.
Arrange pressure sensor in ajutage, described pressure sensor is connected with intelligent controller.
Intelligent controller also arranges remote communication module.
Described electric air valve actuator is communicated by RS485 with between intelligent controller.
Compared with existing control technology, the utility model has control effects useful as follows:
The utility model arranges CO by isolated area
2sensor accurately judges certain region CO
2whether concentration exceeds standard and automatically regulates resh air requirement according to the quantity that also basis exceeds standard.As CO in air
2concentration reaches the hop count that demand concentration progressively lowers new fan delivery.At the ajutage setting pressure controller of new blower fan, segmentation Isobarically Control can prevent airduct from uttering long and high-pitched sounds.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with concrete example, the utility model is described in further detail, and described is to explanation of the present utility model instead of restriction.
As shown in Figure 1, a kind of new wind multizone CO of the utility model
2control device, comprise the new wind unit that intelligent controller 1, new blower fan 2 and each room are arranged, interim described new wind unit comprises electric air valve actuator 3 and CO
2sensor 4, the air intake of new blower fan connects new wind by fresh wind tube 5, and the air outlet of new blower fan is by ajutage 6 and each room UNICOM, and the air outlet in each room arranges electric air valve actuator and CO
2sensor, CO
2sensor is connected with intelligent controller respectively with new blower fan.
Arrange pressure sensor 7 in ajutage, described pressure sensor 7 is connected with intelligent controller 1.
Intelligent controller also arranges remote communication module.
Described electric air valve actuator is communicated by RS485 with between intelligent controller.
Systematical control principle
1, Fresh air handling units air inlet arranges motor switch air-valve, and link with Fresh air handling units state, header pipe arranges pressure sensor.
2, each region arranges CO
2sensor, arrange according to region area, region air outlet arranges electric control valve.
3, control system is according to the region CO gathered
2concentration values compares with setting value, if exceed standard, control band powered supplied air valve opening, ensures that IAQ is up to standard.
4, control system compares with settings according to header pipe's pressure sensor detected value, regulates new wind air quantity, keeps blast pressure constant.
5, each intelligent control unit is by communication interface, realizes the data remote detecting data field running status.
The utility model carries out control and the adjustment of relevant device according to the change of controling parameters; The running status of the new blower fan of dynamic monitoring etc. and energy consumption data; Different according to the position of forced draft, the cellular system taken various forms; Accept network system (or other system) instruction by 485 communication interfaces, and the service datas such as pressure fan are fed back to network system.
