The specific embodiment
Below be relevant the specific embodiment of the present invention, please refer to drawing.
Embodiment one:
Fig. 1 is the air conditioner structure figure of embodiment of the present invention, because freeze cycle and operating principle do not have direct relation with purport of the present invention, in addition, existing structure is also passable, therefore omits diagram and related description at this, and control loop once mainly is described.
Among Fig. 1,1 is AC power, and 2 is indoor set, and 3 is off-premises station, and 31 is rectifier, and 4 is frequency converter, and 5 is compressor, and 6 is relay, and 7 is the direct-acting electromagnetic valve as the air conditioner refrigerating components and parts, and 71 is the drive coil of magnetic valve 7, and 8 is the variable resistor device; The drive coil 71 of magnetic valve 7 constitutes the major part (the less important part of control loop such as binding post etc. constitute the necessary part in loop, do not give unnecessary details at this) of control loop with variable resistor device 8.
According to above structure,, DC voltage is supplied with control loop by relay 6.Variable resistor device 8 is served as by positive characteristic temperature coefficient device 8R, be specially thermistor (to call PTC in the following text) and constitute, by this structure according to characteristic shown in Figure 2 drive coil 71 supply capabilities to magnetic valve 7.
What Fig. 2 described is the characteristic of voltage and electric current, and the longitudinal axis is represented voltage V and electric current I, and transverse axis is represented time T.The voltage of this characteristic and electric current supply drive coil 71.Among Fig. 2:
Curve d represents: the variation characteristic of resistance value R that serves as the thermistor 8R of variable resistor device 8;
Curve c represents: the electromagnetic force variation characteristic of drive coil 71;
Curve b represents: the variation characteristic of current value I;
Curve a represents: magnitude of voltage V characteristic;
Among Fig. 2, set by the best thermistor 8R, it is certain that the magnitude of voltage V of characteristic a keeps, when thermistor 8R resistance value R such as characteristic curve d are shown in low-resistance value d1 state, high current value b1 when the current value I of curve b becomes magnetic valve 7 and starts offers the drive coil 71 of magnetic valve 7.As a result, coil 71 occurs as the high electromagnetic force of curve c, and magnetic valve 7 starts as core iron (nothing illustrates) moves, the state when being start and beginning.After this release,, make the resistance value R of thermistor 8R shown in characteristic curve d, become high resistance d2 because the temperature of thermistor 8R rises.As a result, the electric current I of supplying with coil 71 becomes low current value b2 shown in characteristic curve b, and the low electromagnetic force of characteristic c appears in coil 71, has guaranteed the low current that action keeps, and keeps action and keeps.The thermistor 8R of the concrete structure by control loop 8 shown in Figure 1, offer the electrical power of the drive coil of magnetic valve 7 in the control chart 2, when magnetic valve 7 actions, can pass through high current value safety action electric current, and make reliable in action carry out (being the action launching state), after the release, guarantee the maintenance electric current of low current, reliably keep its action and keep (promptly move hold mode).
Therefore, can realize reducing the consumed power of coil 71, the air-conditioning of power saving is provided.
And, because variable resistor device 8 is served as by positive characteristic temperature coefficient device 8R, be specially thermistor (to call PTC in the following text) and constitute, control loop is oversimplified, in the space of saving air-conditioning, also realize the miniaturization of low-cost and air-conditioning.
Embodiment two:
Therefore Fig. 3 has only the different of control loop structure with Fig. 1, with the prosign that indicates of Fig. 1 same section, omits explanation to it at this.Among Fig. 3, variable resistor device 9 is formed in parallel by positive characteristic temperature coefficient device 9R and fixed resistance 91, and positive characteristic temperature coefficient device 9R is served as by thermistor.Same, the drive coil 71 of magnetic valve 7 constitutes the major part (the less important part of control loop such as binding post etc. constitute the necessary part in loop, do not give unnecessary details at this) of control loop with variable resistor device 9.
Among Fig. 3, thermistor 9R is in parallel with fixed resistance 91, and an end of its tie point links to each other with relay, and an other end links to each other with an end of coil 71, and an other end of coil 71 links to each other with the capacitor 32 of off-premises station 3.
In the above structure, by the optkmal characteristics of thermistor 9R are set, as shown in Figure 4, the magnitude of voltage V of characteristic a1 keeps necessarily, and the current value I of characteristic curve b2 is lower than the thermistor 9R of fixed resistance 91 by resistance value, forms bigger current value I b1 and imposes on coil 71, action current when having guaranteed to start, as a result, as the electromagnetic force of the coil 71 of magnetic valve 7, carry out the action the same (being the action launching state) with above-mentioned action; After the above-mentioned release, utilize the variation characteristic that becomes the thermistor 9R of high resistance owing to the temperature rising, current value I forms low current value I b2 by the fixed resistance 91 of resistance value far below thermistor 9R, as keeping electric current to offer coil 71, keep action thereby keep.
The concrete structure of the variable resistor device 9 by as shown in Figure 3 obtains electromagnetic force and the resistance change characteristic same with Fig. 2, the electric current I b2's the when current value I among Fig. 4 can realize forming electric current I b1 when starting and action and keeps.
Among Fig. 4, the longitudinal axis is represented voltage and current value, and transverse axis is represented temperature.
Therefore, according to the structure of the combination in parallel with fixed resistance of PTC among Fig. 3, PTC can be set at optkmal characteristics, obtains to possess the setting of certain free degree.Because PTC and fixed resistance parallel connection, can effectively avoid the individual difference that single PTC causes because of manufacturing (when using the individual Yin Wendu of each PTC raise its high resistance fluctuation range widely different), make all-in resistance after the parallel connection more level off to the characteristic that requires; In other words, Bing Lian fixed resistance has weakened the individual difference of single PTC.
In the form of above embodiment, positive characteristic temperature coefficient device has adopted thermistor, also can use other positive characteristic temperature coefficient device.
