The key of present embodiment is on the basis of the closure that guarantees refrigeration (heat) system, can realize Based Intelligent Control and the exchange gas external world, and main purpose is in time harmful (danger) gas in the closed system to be discharged.
So-called intelligence ventilation is meant that the action of ventilation is to be discerned automatically according to certain pre-conditioned and certain principle by the control system of air-conditioning self, and control is accomplished automatically.The main principle of foundation is safe and energy-conservation.So-called safety be meant control system can own detecting box in the concentration of harmful (danger) gas, whenever guarantee that through automatic vent harmful (danger) gas can not exceed standard in the cabinet.The ventilation duration also can be confirmed based on the concentration of harmful (danger) gas.So-called energy-conservation being meant guaranteed the energy loss minimum in scavenging period.
In order to achieve the above object; Native system should comprise an intelligent controller that contains single-chip microcomputer; Can gather outer temperature of cabinet and the probe that is harmful to (danger) gas concentration in the cabinet for one group; And accomplish the control and drive circuit and relevant conversion and interface circuit that ventilation is moved, also have a cover machine driving and an actuator certainly.One cover Intelligent Recognition Control Software also is the indispensable part of this system.
The mechanical structure of air exchange system is as shown in Figure 1.This device comprises that but one is installed in the ventilation door 2 of the folding on 1 body of air-conditioning chamber, the mechanical device of control ventilation door 2 foldings and the motor 3 of drive mechanism action, and motor adopts the 12V direct current machine.
The concrete working method of present embodiment ventilation door 2 ventilations is following:
Under the normal condition, ventilation door 2 is in closed condition, and sealant 9 can guarantee fully that air-conditioning chamber 1 and the space that needs temperature control constitute the space of complete closed, guarantee the effective energy-saving working method.
When direct current machine 3 counter-rotatings, drive screw rod 4 and reverse synchronously, promote slide block 5 and move to direction away from motor, slide block 5 drives push rod 6 and moves simultaneously, opens so promote ventilation door 2.
When direct current machine 3 was just changeing, driving screw rod 4 just changeed synchronously, and pulling slide block 5 moves to the direction near motor, drove push rod 6 and moved simultaneously, so pulling ventilation door 2 is closed.
Direction through changing the screw thread on the screw rod 4 also can be opened the door when motor just changes, and closes the door during counter-rotating.
Ventilation door 2 is by with processor (single-chip microcomputer) be control system basis that core the constitutes realization Based Intelligent Control that imposes a condition in the present embodiment.Ventilation door 2 normally is in closed condition, fully guarantees the requirement of air-conditioning system sealing work, guarantees the maximum energy-saving working method.When detecting harmful (danger) gas, system reached certain concentration; When affirmation needs exhaust; System promptly gets into intelligent vent sequence, and single-chip microcomputer can be chosen in a release (being generally one day) in the period automatically, control exhaust when the temperature difference in the cabinet, outside the cabinet is minimum.Send the exhaust instruction by single-chip microcomputer, open ventilation door 2, fresh air outside is sucked in the air-conditioning chamber 1, will be harmful to (danger) gas simultaneously and discharge by internal fan.Exhaust reached after the scheduled time, and single-chip microcomputer can send instruction again and cut out ventilation door 2.
The drive controlling of ventilation door 2 is accomplished by the specially designed simple and reliable circuit of a cover in the present embodiment, and principle is shown in figure two.The 12V power supply is through a double-point double-throw switch K 1Be connected to direct current machine 3.K 1During release ,+12V power supply can make direct current machine just change K 1During adhesive ,+12V power supply can make the direct current machine counter-rotating.Whether direct current machine rotates then also receives other two limit switch K 2, K 3Control, K 2For closing door limit switch, K 3Be the door open limit switch.The break-make of these two switches then receives the control of slide block 5.Two switches are closure when not receiving slide block 5 compressings, become open circuit when receiving slide block 5 compressings, can find out that on structure slide block 5 can not oppressed two limit switches in switch door process.Have only when slide block 5 and just can oppress a switch in two switches during at the two ends extreme position.
We at first have a look the process of closing the door, K at closing time 1Be in release condition, when door is closed by opening, K 2It is closed not suffering oppression, as long as+12V has electricity, and direct current machine 3 promptly can just change pulling and close the door.When door is closed fully, when sealant 9 had sealed door, slide block 6 was just in time pushed down and is closed door limit switch K2, so K2 breaks off, cut off the 12V power supply, the direct current machine stall, and ventilation door 2 stops at closed condition.
Under the state of closing the door, as long as single-chip microcomputer is seen a high level off to switch gate control end and made double-point double-throw switch K 1Adhesive, make+the 12V power supply delivers to direct current machine with reverse state, and this moment is because limit switch K 3Do not suffer oppression, circuit is in on-state, and direct current machine reverses immediately, so ventilation door 2 begins to open.When door is opened to a certain degree, when promptly slide block 5 compressing door open limit K switch 3 made its disconnection, the 12V power supply was cut off, the motor stall, and ventilation door 2 stops at the state that is opened.
Under the state that ventilation door 2 is opened, close the door if desired, only need single-chip microcomputer to see a low level off to switch gate control end, make K switch 1Discharge and both can.Because K switch 2Be released already, so when the instruction of closing the door was sent, direct current machine can just change immediately closed the door.
Because automatically ventilation is one and relates to safe important action, must meet the standard of zero tolerance, we also are equipped with another group transducer on the position of switch door, in order to confirming the state of door, will confirm that by them a signal of opening (pass) gives single-chip microcomputer.If any fortuitous event, behind (closing the door) signal that opens the door such as sending, do not receive the signal of door opened (closing), will report to the police immediately.
Be in the mobile machine station under the open-air unattended operation state; The remote monitoring that realizes its power, environment and running status is very important; And the signals collecting of rotating ring monitoring and arrangement are gathered among the control system that is placed into special air conditioner, obviously be a solution the most easily.Therefore, the function of our integrated rotating ring monitoring in the control system of this air-conditioning.
