The utility model relates to a constant temperature and constant humidity air conditioner, particularly a quasi-continuous control air conditioner humidifier circuit board. In a control system A1, a relay KA1 is connected with a switch control board to input humidifier voltage; two auxiliary relays KA2, KA3 are additionally arranged in the control system; the auxiliary relays are respectively connect with the switch control board and an auxiliary circuit board which is externally and additionally arranged. The utility model can realize three-step control to cause humidifier precision to be accurate when relative humidity approaches; that is to say, the humidifier board after reformed realizes quasi-continuous control of ECOM; the humidifier precision is enhanced. Because the proposal directly supplies power for an ECOM board, signals have no delayed imagination; the problem of influencing control precision does not exist. The utility model automatically processes and limits the maximal humidifier quantity by directly taking out three voltages in the three-step control; the current of humidifier electrodes is limited.

Description
Technical field:
The utility model relates to air-conditioning unit, particularly constant-temperature constant-humidity air-conditioner.
Background technology:
Existing market increases the demand of constant-temperature constant-humidity air-conditioner, and is strict especially to humidification control accuracy requirement partly wherein.The humidification of constant-temperature constant-humidity air-conditioner partly adopts the electric pole type Steam humidifier on the whole, and its core component is the humidification control panel, and its control accuracy has influence on the precision of whole humidification system, or even the performance of air-conditioning unit.The humidification control panel has two kinds of control modes substantially: switch control (ECOM) and continuous control (ECCM).ECOM plate control operation simple (100% humidification), the humidification precision is not high, though cost is low, is not widely adopted.And the ECCM plate has the CPU of oneself, can the realization ratio regulate control humidification amount, therefore costs an arm and a leg.The ECCM plate need be by outside humidity controller control, and this has determined the precision of peripheral control unit directly to have influence on the control accuracy of ECCM plate.And the output signal of peripheral control unit can produce time-delay when feeding back to the CPU of ECCM plate, and the control accuracy of ECCM plate is reduced, but generally speaking than the control accuracy height of ECOM plate.The humidifier that uses the ECOM plate is in humidification, to continue with maximum humidification amount (for example 13kg/h) humidification, when the relative humidity of outside humidity sensor detection reaches requirement, control system is sent and is stopped the humidification instruction, humidifier quit work (humidifying plate outage), but because the humidification amount is excessive, can not stop humidification at once, tend to cause relative humidity to surpass like this humidity is set, if at the environment that requires the comparison strictness, also to start compressor and carry out refrigerated dehumidification, cause waste in many ways.
Summary of the invention:
The objective of the invention is to overcome above-mentioned not enough problem, a kind of quasi-continuous control air-conditioner humidifying circuit board is provided, air-conditioning switch is controlled and had the control accuracy that compares favourably with continuous control, and is with low cost.
The technical scheme that the utility model is adopted for achieving the above object is: a kind of quasi-continuous control air-conditioner humidifying circuit board, there is relay K A1 to link to each other among the control system A1 with the switch control panel, input humidification voltage, add 2 auxiliary reclay KA2, KA3 in control system, auxiliary reclay links to each other with switch control panel and the outside auxiliary circuit board A2 that adds respectively.
Two fixed value resistance R1 in the described auxiliary circuit board A2 and R2, R1＜R2.
Described control system A1 is provided with relay K A1, the voltage input pin of its external pin SK5-15, SK5-16 switch control panel A3 links to each other, on A1, add two auxiliary reclay KA2, KA3, KA2 external pin SK5-11 links to each other with resistance R 2 among the auxiliary circuit board A2, SK5-12 links to each other with the voltage acquisition point of switch control panel, KA3 external pin SK5-13 links to each other with resistance R 1 among the auxiliary circuit board A2, and SK5-14 links to each other with switch control panel voltage acquisition point.
The utility model is according to the operation principle of ECCM plate, the subprogram of appending to the control system (single-chip microcomputer) of existing air-conditioning unit, auxiliary circuit board of outside increase, relative humidity near the time, can realize three grades of controls, make the humidification ratio of precision more accurate, we can say that improved humidifying plate realized the quasi-continuous control of ECOM, improved the humidification precision, this programme is because of directly powering to the ECOM plate, signal does not have the time-delay imagination, do not have the problem that influences control accuracy, it is by three voltages in three grades of controls of direct taking-up, handles the maximum humidification amount that limits automatically, promptly limit the electric current of humidifying electrode, we can say that the control accuracy of transforming the back humidifying plate can compare favourably in the ECCM plate.
Description of drawings:
Fig. 1 is the utility model circuit diagram.
Fig. 2 is the utility model control system circuit diagram.
Fig. 3 is the utility model humidification control program schematic diagram.
The specific embodiment:
As Fig. 1, control system A1 shown in Figure 2 is provided with relay K A1, its external pin SK5-15, SK5-16 switch control panel A3 voltage input pin links to each other, on A1, add two auxiliary reclay KA2, KA3, the outside adds auxiliary circuit board A2, two fixed value resistance R1 in the auxiliary circuit board A2 and R2, R1＜R2, its function is by changing the loop resistance value, thereby feed back to the different voltage signal of switch control panel, KA2 external pin SK5-11 links to each other with resistance R 2 among the auxiliary circuit board A2, SK5-12 links to each other with switch control panel voltage acquisition point, KA3 external pin SK5-13 links to each other with resistance R 1 among the auxiliary circuit board A2, and SK5-14 links to each other with switch control panel voltage acquisition point.
The utility model course of work is as follows: suppose present unit be positioned at humidity be 38% indoor, the client is by being set at 45% with humidity on the controller, because humidity is not enough in the space, unit work, control system is sent humidification indication, this moment relay K A1, KA2, KA3 coil electricity, SK5-15 and SK5-16 conducting, SK5-11 and SK5-12 conducting, SK5-13 and SK5-14 conducting.Give ECOM plate power supply (24VAC) by SK5-15 like this, R1, R2 short circuit on the auxiliary circuit board, the no-voltage loss, the voltage that feeds back to the ECOM plate is 4.16VDC (corresponding humidification amount 13kg/h), can add wet current 14.04A by detection, form third level humidification like this.When ambient humidity is raised to 43%, KA1, KA2 coil electricity, SK5-15 and SK5-16 conducting, SK5-13 and SK5-14 conducting, R2 short circuit this moment, feedback voltage is 2.01VDC (corresponding humidification amount 8.6kg/h), adds wet current 9.26A, this is a second level humidification.Along with environment temperature constantly give birth to high, when reaching 44%, the KA1 coil electricity, this moment voltage through R1 and R2, feedback voltage is 0.2VDC (corresponding humidification amount 4.3kg/h), adds wet current 4.63A, the first order humidification of Here it is humidifier.(referring to Fig. 3)
When relay makes up with different open and closes, corresponding humidification amount such as following table:
| Maximum humidification amount | Humidification amount (Kg/h) | ||
| 100％ | 66％ | 33％ | |
| KA1 | Close | Close | Close |
| KA2 | Close | Open | Open |
| KA3 | Close | Close | Open |
