MEMS (MEMS, Micro-Electro-Mechanical System) silicon valve can be used as a kind of throttle valve
Product, using the working method of pilot valve driving main valve.Its pilot valve uses the silQflo based on MEMS technology, electrothermal drive
Silicon fluidic chip can realize expansion valve to linear, the proportion adjustment of refrigerant flow using pwm signal.The embodiment of the present invention
In, in cold-heat exchange system equipment, MEMS silicon valve is used, to carry out the adjusting of cold medium flux, MEMS silicon valve not only has out
The fireballing advantage of valve is closed, also, also overheating protection can be carried out to compressor by temperature controller, and when degree of superheat concussion
Between short, energy saving of system excellent effect.
MEMS silicon valve is mainly made of pilot valve and main valve, and pilot valve is one electrically driven (operated), linear, silicon materials micro electronmechanical
System.Pilot valve receives and transmits a linear driving pressure to the spool of main valve after an electric signal, in addition spring force is to balance
Driving pressure, therefore spool is as pilot valve moves.Also, in the embodiment of the present invention, there is an Intelligence Feedback mechanism, this is anti-

In the embodiment of the present invention, it further includes temperature controller that MEMS silicon valve, which not only includes the adjustable valve of aperture, can basis
The temperature that temperature controller detects carries out the PREDICTIVE CONTROL of single channel PWM form to MEMS silicon valve.
Fig. 1 is a kind of flow chart of cold-heat exchange system control method shown according to an exemplary embodiment.Certainly, cold
Heat-exchange system includes: the compressor for changing refrigerant physical state in cold-heat exchange system, and adjusts the MEMS of cold medium flux
Silicon valve, wherein the temperature controller in MEMS silicon valve is arranged in the coil of compressor.As indicated with 1, cold-heat exchange system controls
Process include:
Step 101: by the temperature controller having been turned on, obtaining the present coil temperature of compressor coil.
In the embodiment of the present invention, cold-heat exchange system includes compressor, and compressor is at work, and compressor displacement is also easy to produce
Heat will result in the decline of compressor service life and performance decline if be not excluded for.It include temperature control in MEMS silicon valve
Therefore device temperature controller can be arranged in the coil of compressor, in this way, after temperature controller starting, it can be by having been turned on
Temperature controller, obtain compressor coil present coil temperature.Preferably, can be passed by the temperature in temperature controller
Sensor obtains the Current Temperatures parameter of compressor coil, thus, processing module can be according to the current of acquisition in temperature sensor
Temperature parameter obtains the present coil temperature of compressor coil.
Step 102: when present coil temperature is greater than given threshold temperature, the aperture of MEMS silicon valve is tuned up into setting value,
To reduce the load of compressor.
If the heat due to compressor is not excluded for, the decline of compressor service life and performance decline will result in, it therefore, can
A threshold temperature is preset, when the coil temperature of compressor is more than this threshold temperature, it may be determined that compressor has heat
Amount, needs to take safeguard measure, at this point, the aperture of MEMS silicon valve can be tuned up, in this way, cold medium flux becomes larger, the function of compressor
Rate can become smaller, thus, reduce the load of compressor.
The aperture of MEMS silicon valve can be tuned up setting value according to the concrete model of MEMS silicon valve, such as: it can be adjusted from closing
To opening, alternatively, the second opening value can be adjusted to from the first opening value of MEMS silicon valve, between the first opening value and the second opening value
Poor one, two or more setting shelves values.Since the MEMS silicon valve reaction time closes 200 milliseconds hereinafter, therefore, adjusting from standard-sized sheet to complete
Big MEMS silicon valve process is very fast, less than 200 milliseconds, improves the time that valve adjusts in cold-heat exchange system, also improves
Change the efficiency of compressor load.
As it can be seen that MEMS silicon valve is used, to carry out the adjusting of cold medium flux, MEMS silicon valve in cold-heat exchange system equipment
Not only have the advantages that switch valve is fireballing, also, also overheating protection, and mistake can be carried out to compressor by temperature controller

In the 0.2S time), therefore, using the cold-heat exchange system of the MMEMS valve silicon than 30% or more ordinary electronic expansion valve energy conservation.
Meanwhile MEMS silicon valve can also be upgraded by remotely monitoring, temperature controller in the MEMS silicon valve that timely updates
Temperature algorithm or other MEMS silicon valves control software, this way it is ensured that MEMS silicon valve reaction speed, long-range realization product
Upgrading, reduces the consuming to hardware.
Certainly, in the embodiment of the present invention, when present coil temperature is less than or equal to given threshold temperature, MEMS silicon is maintained
The aperture of valve is constant.In this way, maintaining the steady operation of cold-heat exchange system.
Due to MEMS silicon valve instead of in cold-heat exchange system it is existing adjust cold medium flux electronic valve, electronics
The function that valve has, MEMS silicon valve also need to have, can according to carried in the user instruction received temperature parameter, environment temperature
At least one parameter in humidity parameter and operating mode parameter adjusts the aperture of MEMS silicon valve.This way it is ensured that cold and hot
The existing capability of exchange system, also, since MEMS silicon valve has the advantages that switch valve is fireballing, further improve cold and hot friendship
The reaction time of system is changed, so that the effect of also improving cold-heat exchange system, also improves the experience of user.
Since the temperature controller in MEMS silicon valve is used for the overheating protection of compressor, when determining that compressor stops
When only working, closing temperature controller, thus, the consuming of resource can be saved.

Row step 206.
Step 205: the aperture of MEMS silicon valve being tuned up into setting value, and executes step 207.
If MEMS silicon valve is to close, this step can open MEMS silicon valve.If the aperture of MEMS silicon valve is smaller, can
The aperture of MEMS silicon valve is tuned up, in this way, the cold medium flux that compressor passes through becomes larger, the load of compressor can be reduced, to subtract
The temperature of low compressor realizes the overheating protection to compressor.
Step 206: maintaining the aperture of MEMS silicon valve constant, and return step 207.
It is still closed if MEMS silicon valve, if MEMS silicon valve is the first aperture, then it is assumed that first aperture etc..
Step 207: judging that compressor stops working? if so, executing step 208, otherwise, return step 203.
Step 208: closing temperature controller.
