Description
Technical field
The utility model provides the new fan operation controller of a kind of central air-conditioning, particularly relates to a kind of operation controller that can carry out time setting, belongs to electro-mechanical arts.
Background technology
All central air-conditioning being installed in current building, in central air-conditioning, generally all Aided design can being installed by new blower fan, for improving indoor environment, regulating air quality.New blower fan is a kind of effective air cleaning facility, room air can be made to produce circulation, on the one hand outside the air discharge chamber of foul indoor, on the other hand outdoor ozone through sterilization, after the measures such as sterilization, filtration, be input to indoor again, allowing in room is all the air of fresh clean all the time.
But new blower fan and the fresh air pipeline of design and installation in building system at present in most of the cases do not use, main cause is the Starting mode inconvenience of traditional start/stop, more and the staff of new blower fan quantity because of Mei Dong building after generally opening not in time or forget closedown, significantly increase operation of air conditioner energy consumption, cause air-conditioning system operating cost high, staff is difficult to accept thus do not open new blower fan without hesitation, so the VMC in the central air-conditioning of general building is in most cases ornaments, both investment was added, regulating action is not had again to improving air quality.
Summary of the invention
The utility model provides the new fan operation controller of a kind of timeliness, solves the deficiency in background technology, and this controller can control automatically to new blower fan, makes its intermittent unlatching automatically, greatly reduces energy consumption.
Realizing the technical scheme that the utility model above-mentioned purpose adopts is:
The new fan operation controller of a kind of timeliness, at least comprise hand control switch and new blower fan major loop, breaker is provided with in described new blower fan major loop, fuse and electrothermal relay, also be provided with change-over switch, the time relay, run switch and contactor, described time relay manner of execution be electric time delay, the time relay is provided with two, be respectively very first time relay and second time relay, wherein the normally opened contact of very first time relay and the coil tandem of contactor are the first sequential circuit, it is the second sequential circuit that the coil of second time relay is connected in series with contactor normally opened contact, the normally closed electric shock of second time relay and the coil tandem of very first time relay are the 3rd sequential circuit, above-mentioned three sequential circuits also connect rear formation automatic control loop, be connected in series with contactor coil after described run switch is connected in series with hand control switch again and form Non-follow control loop, hand control switch and contactor normally opened contact also connect formation self-locking, automatic control loop is all connected with selector switch with Non-follow control loop, is provided with automatic catch, manual and lock catch in described selector switch, and when being switched to automatic catch, automatic control loop connects new blower fan major loop by selector switch, when being switched to manual, Non-follow control loop connects new blower fan major loop by selector switch.
Described major loop is provided with power supply indicator.
Run indicator is serially connected with after described contactor coil.
The timeliness that the utility model provides new fan operation controller compared with prior art has following advantage: this controller can improve the method for operation of original new fan starting/stopping, be provided with manual and automatic two kinds of patterns, need under manual mode artificially manually to control new blower fan, in automatic mode can by carrying out set of time to the time relay, thus new blower fan intermittence is opened, stop 20 minutes as being set to unlatching after two minutes.So, can either ensure that outdoor fresh air enters indoor and improves indoor air ambient, energy consumption can be reduced greatly again.
Accompanying drawing explanation
The circuit diagram of the new fan operation controller of timeliness that Fig. 1 provides for the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed specific description is done to the utility model.
The circuit diagram of the new fan operation controller of the timeliness provided in the present embodiment as shown in Figure 1, at least comprise hand control switch ST2 and new blower fan major loop, in described new blower fan major loop, be provided with circuit breaker Q F, fuse FU and electrothermal relay KH and power supply indicator HR.In described controller, sea is provided with change-over switch SAC, the time relay, run switch ST1 and contactor KM.Described time relay manner of execution be electric time delay, the time relay is provided with two, be respectively very first time relay K T1 and the second time relay KT2, wherein the normally opened contact of very first time relay K T1 and the coil tandem of contactor KM are the first sequential circuit, it is the second sequential circuit that the coil of the second time relay KT2 is connected in series with contactor KM normally opened contact, the normally closed electric shock of the second time relay KT2 and the coil tandem of very first time relay K T1 are the 3rd sequential circuit, and above-mentioned three sequential circuits also connect rear formation automatic control loop.
Form Non-follow control loop with contactor KM coil tandem again after described run switch ST1 is connected in series with hand control switch ST2, after described contactor KM coil, be serially connected with run indicator HG.Hand control switch ST2 and contactor KM normally opened contact also connect formation self-locking.
Above-mentioned automatic control loop is all connected with selector switch SAC with Non-follow control loop, is provided with automatic catch, manual and lock catch in described selector switch SAC, and when being switched to automatic catch, automatic control loop connects new blower fan major loop by selector switch; When being switched to manual, Non-follow control loop connects new blower fan major loop by selector switch.
The operation principle of the timeliness that the present embodiment provides new fan operation controller is as follows: when change-over switch SAC is positioned at right position manual gear, 1., 2. contact is connected, and Non-follow control loop connects new blower fan major loop.Now closed hand control switch ST2, contactor KM coil obtains electric, and contactor normal open switch KM is closed forms self-locking, and run indicator HG is bright, and blower fan brings into operation, and manually presses run switch ST1, and circuit is cut off, and new blower fan is out of service, realizes Non-follow control.
When change-over switch SAC is positioned at left position automatic catch, 3., 4. contact is connected, and automatic control loop connects new blower fan major loop.Second time relay KT2 normally-closed contact is in the normal state closed, very first time relay K T1 coil obtains electric, after time expand T1, very first time relay K T1 normally opened contact KT1 closes, contactor KM coil obtains electric, contactor KM normal open switch closes, run indicator HG is bright, and new blower fan brings into operation.While contactor normal open switch KM is closed, the second time relay KT2 coil obtains electric, the second time relay KT2 normally-closed contact action after time expand T2, KT2 normally-closed contact disconnects, very first time relay K T1 coil losing electricity, due to the present embodiment select the time relay be electric time delay, so switch immediate response during power down, very first time relay K T1 normally opened contact disconnects, contactor KM coil losing electricity, contactor KM switch disconnects, second time relay KT2 coil losing electricity, second time relay KT2 normally-closed contact is closed open type new round circulation again, thus realize automatically controlling, time expand T2 is the fan operation time.Can realize disconnecting after the T1 time by this and start the T2 time, suppose that ratio according to 10:1 is to arrange T1 and T2, so energy consumption is only original 10%.
