By above-mentioned logic control method, the three zones of all-in-one machine are realized:
Fresh air system operation function: when system detection to outdoor temperature is lower than room temperature, and indoor and outdoor temperature difference is less than 8
Degree Celsius, then start fresh air system, outdoor air is come in from the fresh air outdoor air inlet of fresh air conditioner all-in-one machine at this time, passes through the
Primary filter is then passed through second level filter screen, then by following blower, then by fixed blinds export all-in-one machine, wind direction
Be downwardly into interior, while indoor high temperature air be discharged to outdoor by air exhaust passage, realize the extraneous cleaned air of low temperature into
Come, the interior of high temperature is gone out this cyclic process.
Air-conditioning system operation function: when fresh air system operation, if high temperature alarm occurs in room temperature, indoor and outdoor temperature is poor
When greater than 8 degrees Celsius, the blower of fresh air system is closed, and closes air exhaust passage Electric air valve, indoor and outdoor air circulation is blocked, opens
Dynamic air-conditioning system, at this moment compressor starts work, and evaporator fan and condenser fan are started to work, evaporator fan work
When, interior of equipment cabinet air enters interior of equipment cabinet, and as channel enters evaporator storehouse, air inside evaporator storehouse, air with
Evaporator fin contacts, and heat is absorbed by fin in air, this is air themperature decline, and evaporator storehouse is discharged and enters in cabinet
Portion.With the flowing of air conditioner coolant, the heat that evaporator absorbs is brought to inside compressor, continues to flow with refrigerant, heat
Amount is finally reached on condenser, condenser fan operation, and for outdoor air by first order filter screen into such as condenser storehouse, this is empty
Gas is contacted with condenser fin, and the heat absorption on condenser wing is taken away, and is discharged big outdoor.This process does not stop circulation fortune
The displacement of interior of equipment cabinet heat is ceaselessly discharged to outdoor by row, realizes cooling rapidly.
In air-conditioning system operational process, room temperature is reduced, when indoor and outdoor temperature difference returns within 8 degrees Celsius, again
Fresh air system is opened, air-conditioning system is closed.Another situation, in air-conditioning system operational process, if appointing in air quality data
It when one item data is higher than preset value, then controls exhaust switch module and reopens, fresh air system operation, air-conditioning system are closed, directly
Into air quality data, all data are below preset value.
Filter net system operation function: when system detection to differential pressure pickup numerical value reaches setting value (0.3kPa), i.e.,
Illustrate that filter screen blocking occurs seriously, at this moment system starts strainer self-cleaning program, and self-cleaning system comes among two-stage strainer
It returns and moves up and down, dust catcher is started to work, and the suction chamber air entry in dust catcher module rubs back and forth in the screen surface of the second level
Cleaning motion is wiped, the dust accumulated on strainer is all drawn into suction chamber, under the action of powerful suction fan, by it
Dirty air is discharged in outlet chamber, then is ejected by the gas outlet of outlet chamber, and the air-flow ejected is directly to the first order
At this moment the bulky grain dust block of accumulation above first order filter screen is blown out to outdoor by filter screen together.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for the common of this field
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In the protection scope of the utility model.
