Description of drawings
Fig. 1 is the utility model structural representation;
In the accompanying drawing, the list of parts of each label representative is following:
1, energy-saving controller, 2, temperature sensor, 3, the pitch power supply box, 4, air-conditioning draught fan, 5, electric control valve, 6, the air-conditioning unit, 7, the refrigerant pipe.
The specific embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
As shown in Figure 1; The described intelligent constant-temperature of the utility model embodiment becomes wind variable water volume energy-saving control system; Comprise energy-saving controller 1, temperature sensor 2 and electric control valve 5; Said electric control valve 5 is by 3 power supplies of pitch power supply box, and an end of electric control valve 5 connects said energy-saving controller 1, and the other end of electric control valve 5 is connected with air-conditioning unit 6 interior refrigerant pipes 7.
When the minimum air quantity of air-conditioning draught fan 4 can not be satisfied the demand; Energy-saving controller 1 is regulated the open degree of electric control valve 5 automatically; Cold/heat medium pipe 7 supplys of control air-conditioning unit 6; Thereby the control break indoor temperature indoor temperature is controlled in the reasonable range, and the air quantity that reduces and the water yield is exactly the energy of practicing thrift.
Said energy-saving controller 1 also comprises rectification module, be the inversion module of alternating current and the driving and the holding circuit that are connected with said master control borad respectively with the DC current inversion.
Said inversion module is connected with air-conditioning draught fan 4 through electric wire; Inversion module also is connected with said driving and holding circuit; The positive input of said inversion module inserts the forward output of rectification module, and the negative input of inversion module inserts the negative sense output of rectification module.
Two over capacity capacitor C 1; The C2 access rectification module of connecting each other; The negative pole of diode inserts the forward output of rectification module, and the resistance R parallel connection inserts on the said diode, and the positive pole of diode inserts the anode of IGCT; The negative electrode of IGCT inserts the negative sense output of rectification module, and the gate pole of IGCT inserts said driving and holding circuit.Described over capacity capacitor C 1, C2, diode connected in parallel and resistance R and IGCT have played the effect of filtering and rectification.
One termination of current sensor is gone on the electric wire that is connected with air-conditioning draught fan 4 to record electric current, passes to master control borad after the other end of current sensor records.
The omnidistance operating index of keeping watch on each module of said driving and holding circuit; The electric current that senses when current sensor is excessive or when other unusual conditions occurring; Driving and holding circuit will be taked safeguard measure; The signal that gives the alarm is given master control borad, does further processing by master control borad again according to nature of trouble.
After the described system of the utility model inserts three-phase 380v, 50Hz alternating current; Convert direct current into through rectification module; Be connected into inversion module through dc bus then, described over capacity capacitor C 1, C2, diode connected in parallel and resistance R and IGCT have played the effect of filtering and rectification.After the single-chip microcomputer of master control borad calculates the temperature gap of return air temperature and design temperature; Carry out PID (proportional-integral-differential) control computing; Convert temperature gap into output frequency; Break-make through IGCT in the control inversion module becomes the identical or close alternating current of output frequency that obtains with the single-chip microcomputer computing to the direct current another mistake through the rectification module rectification, comes to drive air-conditioning draught fan 4 runnings to air-conditioning draught fan 4 power supplies with this alternating current output frequency; Thereby the exploitation speed of control air-conditioning draught fan 4, the change of air-conditioning draught fan 4 rotating speeds also will cause the variation of air-conditioning unit 6 discharges.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
