Abstract
The utility model discloses a temperature controlling wind flow changing controller used for a fan coil pipe. The temperature controlling wind flow changing controller used for a fan coil pipe is a product which belongs to the technical field of an air conditioner. The temperature controlling wind flow changing controller used for a fan coil pipe is composed of a temperature sensitive element and an electronic line. The low rotary speed and the high rotary speed of a fan motor are controlled according to the declination of the real value and the rated value of room temperature, and automatic wind flow change is realized; meanwhile, the temperature controlling wind flow changing controller used for a fan coil pipe can control the opening and the closing of an electric water valve.
Description
The utility model relates to the controller of air conditioner with blower and coiled tube temperature control variable air flow and water route switching.
Air conditioner with blower and coiled tube, at home and abroad hotel, restaurant are widely used at present, but and the temperature detect switch (TDS) of its supporting temperature that controls environment, all can not control automatic air quantity by temperature, the change of air quantity is moved or rotation two-speed or three speed switch by artificial, change the fan motor rotating speed and realize, and need two-phase capacitor motor or the additional multitap auto-transformer of two tap capacitor motors of four taps.Temperature detect switch (TDS) and Chinese utility model patent as U.S.'s Honeywell (HONEYWELL) company: 85203171.8 room thermostats all are like this.
The purpose of this utility model is that a kind of controller with ambient temperature control high and low two kinds of rotating speeds of blower fan and water route break-make will be provided, and has light switch and possess power saving function.Only need two tap two-phase capacitor motors with sort controller, do not need many taps capacitor motor or additional multitap auto-transformer.The purpose of this utility model is achieved in that

1Substrate, when having only two pulses to occur simultaneously, three plate pipe BG
1Could saturation conduction, therefore change the pulse distance of RC ring multivibrator, can change zero-crossing pulse and in the identical time, pass through BG
1The quantity of base stage.When relay J is closed, R
11Short circuit, approach O the interpulse period that ring multivibrator produces, and is similar to high level output, and the base stage that makes zero-crossing pulse can all be added to triode triggers controllable silicon, makes controllable silicon SCR
1Each all sinusoidal wave energy is passed through, and fan motor M is in full speed running.Room temperature is higher than when calming the value certain value, and the current potential that electric bridge A is ordered will be lower than the current potential that B is ordered, and makes amplifier output+12V through umklapp transformation O volt, makes BG
1By making controllable silicon SCR on the one hand
2Turn-off, dynamoelectric water valve V closes, and relay J is thrown off, and the pulse that ring multivibrator produces occurs at interval, and blanking time, length was by R
11The resistance decision.Blanking time, zero-crossing pulse can not be added to triode BG
1Base stage, controllable silicon SCR
1Also just be in closed condition, stop to power to fan motor.Motor rotates by inertia, because blanking time is extremely short, is not more than 1/2nd seconds, and the impossible stall of motor shows as rotating speed and reduces on the macroscopic view, and power consumption descends.The control relation of each waveform as shown in Figure 2, waveform 1 is a mains voltage waveform, waveform 2 is the waveform after the full wave rectifier, waveform 3 be the zero-crossing pulse waveform, waveform 4 is the oscillator output pulse waveform, waveform 5 is the voltage waveform that is added on the motor.
