Description of drawings Fig. 1 is each element circuit annexation block diagram of the present invention;
Fig. 2 is the block diagram that is electrically connected with the associated components of the common VMC of forming of the present invention.
The controller of a kind of fresh air energy-saving system of the specific embodiment and control method thereof, its controller mainly are made up of driving power, logic control circuit, indoor temperature transmitter signal receiving circuit, outdoor temperature sensor signal receiving circuit, moisture signal receiving circuit, air intake machine executive circuit, exhaust blower executive circuit, air-conditioning switch executive circuit, display executive circuit etc.Simultaneously, controller and indoor temperature transmitter, outdoor temperature sensor, humidity sensor, air intake machine, exhaust blower, air-conditioning etc. form can with the VMC of air-conditioning interlock.
Embodiments of the invention are described below, but the content of invention is not limited to this:
Embodiment: Fig. 1 is each element circuit annexation figure of the present invention, and Fig. 2 is the block diagram that is electrically connected with the associated components of the common VMC of forming of the present invention.
At first, outdoor temperature sensor and indoor temperature transmitter are installed in the outside in room and the appropriate location of indoor (omit among the figure and draw) respectively, pernicious gas Jian of popping one's head in is contained in indoor place near human body; With air intake machine and the appropriate location of exhaust blower mounted in pairs above room wall or furred ceiling, connect civil power after the present invention connected by the annexation of Fig. 2.The air-conditioning switch executive circuit can adopt existing on the market " universal remote control " know-why in the present embodiment, and the emission wireless signal realizes different types of air conditioners is assert and effectively controlled the Push And Release of air-conditioning.Controller be provided be used for function setting key and display lamp and LCD display be set, can see the situation that is provided with of the function that temperature and each need to carry out.
The control method of the present invention of giving an example below:
1, new wind function: through the logic control circuit setting advance, on the rotating speed of exhaust blower the function for the eliminating indoor pollution that is fit to VMC, its function and existing VMC are just the same, mainly utilize new wind flow and get rid of indoor pollution.
2, cooling energy-saving function: at night in summer (can select for use the new wind that constantly flows to substitute air-conditioning temperature-reducing the daytime that comprises early autumn and Chun Mo), actual showing, about 10 ℃ of the day and night temperatures of this section China in period the greater part.Like night in summer: on the button of controller, be provided with to possess and introduce outdoor new wind condition, the temperature value T1 when air-conditioning can be shut down, also promptly control the temperature threshold values that air-conditioning is shut down.Temperature value T2 when simultaneously, fan starting being set.The set temperature value of opening air-conditioning before if sleep is 26 ℃, T1 can be set so about 26 ℃.T2 can be set to≤T1, and guaranteeing after air-conditioning is shut down, indoor temperature does not also rise when too high, and blower fan introduces new wind lowers the temperature with regard to OnNow.Controller is analyzed indoor temperature transmitter, outdoor temperature sensor temperature detected and compare with the T1 that has been provided with, T2 respectively through microcomputer chip; When outdoor temperature is reduced to T1 or its following numerical value; Controller promptly sends stopping signal through the air-conditioning switch executive circuit to air-conditioning, makes air-conditioning get into stopped status.After this; Indoor temperature can be shut down gradually because of air-conditioning and risen; When indoor temperature transmitter records indoor temperature and rises to the temperature T 2 of setting (T2 can be set to≤T1), controller through advance, the executive circuit of exhaust blower starts air intake machine and exhaust blower, outdoor new wind is introduced into the room.Simultaneously, the air of indoor dirt is discharged outdoor by exhaust blower.At this moment, because system works is interval at fast shelves, indoor air is in quick circulation status, realizes utilizing outdoor cold wind to be the room purpose of lowering the temperature.Like this; Both introduced fresh air, and utilized China's big characteristics of many local day and night temperatures in summer to use the natural air cooling again, one side is saves energy significantly; Avoid closing whole night night in summer the door cooling of turning on the aircondition on the other hand again, it is to have occurred " air conditioner disease " of discomfort because of air is obstructed.
3, function is dyed in safe blowdown: indoor near have a rest and the appropriate location of sleep install be used for the detecting chamber internal contamination like the various sensors to human injury's gas such as formaldehyde, benzene; Logic control utilize gas sensor to detect and through corresponding executive circuit control into, the duty of exhaust blower; When the indoor harmful gas pollution exceeds standard; Will start into, exhaust blower dilution and get rid of indoor harmful gas, reach the purpose of air-safety.
4, the function of drying: when humidity sensor records indoor humidity and exceeds standard, controller through heating with or its work of dehumidifier executive circuit control, ensure the indoor humidity set humidity requirement that suits.
Should; Those of ordinary skills are under enlightenment of the present invention; Also can make other distortion or improvement, as: the internal circuit configuration of converter unit circuit etc., all can realize the object of the invention; In every case do not change controller according to the signal of temperature sensor and to advance, exhaust blower and the interlock of air-conditioning control characteristic, all should be regarded as mentality of designing of the present invention, scheme and protection domain.
