Brief description of the drawings
Fig. 1 is the system module figure of VMC in the embodiment of the present invention.
Accompanying drawing is marked:1st, control module, 2, detection module, 3, executing agency.
Embodiment
Reference picture 1 is described further to the embodiment of the present invention.
A kind of VMC, including control module, power module, display module, detection module and executing agency, display Module, detection module and executing agency are connected with control module;Detection module include PM2.5 sensors, VOC sensors, Indoor temperature transmitter, outdoor temperature sensor, defrost temperature sensor and humidity sensor, executing agency include air-supply Machine, exhaust blower, electrostatic precipitator, defroster, heater and anion generator.
Control module includes central processing unit, keyboard input module, Analog input mModule, AD conversion module, switching value Output module and relay output module;Display module, keyboard input module, Analog input mModule and output switch parameter mould Block is coupled with central processing unit, and the input of relay output module and the output end of switching value output module are coupled, pressure fan, The output of exhaust blower, electrostatic precipitator, the power input of defroster and anion generator with relay output module End coupling.Therefore, Analog input mModule is used for the detection data for inputting each sensor feeding, and detection data pass through AD conversion Central processing unit is sent to after module conversion, central processing unit sends control letter according to detection data to switching value output module Number, the switching value output module, come the work of control relay output module, pressure fan, row is controlled to realize according to control signal Blower fan, electrostatic precipitator, defroster and anion generator start and stop.Keyboard input module is key-press input plate,
The operation principle of the VMC is:The PM2.5 values of room air, VOC sensors are detected by PM2.5 sensors The quality of room air is detected, quality parameter includes formaldehyde, benzene, ammonia, alcohol, carbon monoxide, methane, propane, larane, benzene second The combustion fumes such as the organic volatile such as alkene, propane diols, phenol, toluene gas and cigarette, timber, paper, outdoor temperature sensor inspection Survey outdoor temperature, defrost temperature sensor is mountable to detect the temperature of pressure fan and exhaust blower, blower-use is in will be outdoor Air feeding is indoor, and exhaust blower is used to indoor air being discharged to outdoor, and electrostatic precipitator is used for the fresh air that will be fed into interior Dedusting is carried out, heater is used to heat the indoor fresh air of feeding, realizes the temperature control to room air, anion generator For producing anion, the content of the anion in the indoor fresh air air of feeding is improved.
Another object of the present invention is to provide a kind of control method of VMC, by using this kind of control method, So that more rationally perfect to the control mode of VMC, so as to ensure good ventilation effect and reach the mesh of energy-conservation 's.
To achieve the above object, the invention provides following technical scheme:
When exhaust blower and pressure fan are opened, electrostatic precipitator and anion generator start, and anion generator Stop after the work T1 times, exhaust blower and pressure fan working time add up to reach after the T2 times, are again started up anion generator, and Anion generator stops after the work T1 times;When exhaust blower and pressure fan closing, electrostatic precipitator and anion generator are closed Close.Therefore, the start and stop of electrostatic precipitator are consistent with exhaust blower and pressure fan start and stop, it is ensured that the fresh air of feeding has relatively low Dust content, and anion generator is after a period of time is started, it is automatic to close, it both ensure that containing for anion in room air Amount, reduces energy consumption again.Above-mentioned T1 is 1~60 minute, and T2 is 1~90 hour.
Further, indoor air quality is detected by VOC sensors, and is set according to the sensitivity of VOC sensors Air quality is determined for three kinds of levels of excellent, good, poor, and testing result is shown in real time on display module;
The VMC has multiple-working mode, specifically includes:
Intelligent control mode, when detection module detects indoor air quality difference, control module adjust automatically exhaust blower With pressure fan be high-speed state, when air quality reaches it is good or excellent when, adjustment exhaust blower and pressure fan recover wind speed setting, when When outdoor temperature is less than design temperature P1, control module adjust automatically exhaust blower and pressure fan are that gap is run, and exhaust blower with The rotating speed of pressure fan is kept for startup duration when original state and synchronous gap operation, exhaust blower and the operation of pressure fan gap For T3, dwell time is T4, until when outdoor temperature is more than or equal to P2, exhaust blower and pressure fan recover continuous operation;It is above-mentioned T3 is 1~90 minute, and T4 is 1~90 minute.
Automatic mode, with one week for a cycle, is divided into 6 period operations daily, can be according to the actual requirements to each with note Slot setup exhaust blower and the wind speed of pressure fan is high, medium and low, the 4 kinds of states in pass, and the exhaust blower and pressure fan that the present invention is used are equal For buncher, wherein, the rotating speed of high, medium and low state is respectively 3000rpm, 2000rpm, 1000rpm, and setting operation passes through Keyboard input module realizes that, when VMC is in automatic mode, user to VMC without operating again, fresh air system System can be according to the working condition for being set in each period control exhaust blower and pressure fan with note;Automatic mode needs user manual Control is enabled and exited, and manual mode is entered after exiting.
Manual mode, user can control exhaust blower and turn of pressure fan by keyboard input module according to the actual requirements Speed, operation is very easy;
Anti-freezing pattern, exhaust blower and pressure fan are run for gap, and exhaust blower and the rotating speed of pressure fan keep original state And startup duration when synchronous gap operation, exhaust blower and the operation of pressure fan gap is T5, dwell time is T6;Above-mentioned T5 For 1~60 minute, T6 was 1~90 minute.Anti-freezing pattern needs user to enable and exit manually by keyboard input module, exits Enter manual mode afterwards.
Sleep pattern, when being set as sleep pattern, exhaust blower and pressure fan are the slow-speed of revolution, after the operation T7 times, automatically Sleep function is exited, manual mode is entered after exiting, T7 is 5~10 hours, and sleep pattern is typically enabled at night, both ensure that Control to indoor air quality, can reduce the energy consumption of exhaust blower and pressure fan again, additionally it is possible to which reduction is by exhaust blower and air-supply The noise that machine is caused, the sleep of user is not influenceed.
The VMC that the present invention is provided also has functions of child lock, children's maloperation is prevented, particular by key-press input Module realizes self-locking, therefore, the control method of the VMC provided by using above-mentioned technical proposal, the present invention so that new Wind system has various control pattern, and user can use different control models according to actual conditions, to reach best control Effect, on the one hand ensures that to indoor air quality good control can be reached, on the other hand, can also optimize VMC Operational mode, reach the purpose of energy-conservation.
