Micro-Electro-Mechanical System (MEMS) silicon valve can be used as a throttle valve product, and the operating mode of a main valve is driven by a pilot valve. The pilot valve adopts a silQflo silicon flow control chip based on MEMS technology and electric heating driving, and can realize linear and proportional adjustment of the expansion valve on the flow of the refrigerant by utilizing PWM signals. In the embodiment of the invention, the MEMS silicon valve is adopted in the cold-heat exchange system equipment to adjust the flow of the refrigerant, the MEMS silicon valve not only has the advantage of high valve opening and closing speed, but also can perform overheat protection on the compressor through the temperature controller, and has short superheat degree oscillation time and excellent system energy-saving effect.
The MEMS silicon valve mainly comprises a pilot valve and a main valve, wherein the pilot valve is an electrically driven, linear and silicon micro-electromechanical system. The pilot valve receives an electrical signal and transmits a linear actuation pressure to the spool of the main valve, plus a spring force to balance the actuation pressure so that the spool moves with the pilot valve. In addition, in the embodiment of the invention, an intelligent feedback mechanism is provided, and the feedback mechanism can perform intelligent algorithm processing according to the sensor signal and adjust the valve to perform accurate control, so that the functions of accurately controlling the actuating mechanism and quickly adjusting the valve are achieved. Wherein the MEMS silicon valve reaction time is below 200 milliseconds from full on to full off.
The corresponding equipment of the cold and heat exchange system can comprise: air conditioner, refrigerator, water heater, etc., and these heat exchange systems include: a compressor for changing the physical state of the refrigerant in the cold-heat exchange system, and an adjusting control valve for adjusting the flow of the refrigerant. In the embodiment of the invention, the refrigerant regulating control valve is an MEMS silicon valve, and the original refrigerant regulating control valve in the equipment corresponding to the cold-heat exchange system is replaced by the MEMS silicon valve. For example: the thermal expansion valve in the air conditioner is replaced by an MEMS silicon valve.
In the embodiment of the invention, the MEMS silicon valve not only comprises a valve with adjustable opening degree, but also comprises a temperature controller, and the MEMS silicon valve can be subjected to prediction control in a single-path PWM mode according to the temperature detected by the temperature controller.
FIG. 1 is a flow chart illustrating a method of controlling a heat exchange system according to an exemplary embodiment. Of course, the heat exchange system includes: the cooling system comprises a compressor for changing the physical state of a refrigerant in the cold-heat exchange system and an MEMS (micro electro mechanical systems) silicon valve for adjusting the flow of the refrigerant, wherein a temperature controller in the MEMS silicon valve is arranged in a coil of the compressor. As shown in fig. 1, the process of controlling the heat exchange system includes:
step 101: and acquiring the current coil temperature of the coil in the compressor through the started temperature controller.
In the embodiment of the invention, the cold-heat exchange system comprises the compressor, and when the compressor works, the compressor is easy to generate heat, and if the heat is not discharged and removed, the service life and the performance of the compressor are reduced. The MEMS silicon valve comprises the temperature controller, so the temperature controller can be arranged in the coil of the compressor, and after the temperature controller is started, the current coil temperature of the coil in the compressor can be obtained through the started temperature controller. Preferably, the current temperature parameter of the coil in the compressor can be obtained through a temperature sensor in the temperature controller, and thus, the processing module in the temperature sensor can obtain the current coil temperature of the coil in the compressor according to the obtained current temperature parameter.
Step 102: and when the current coil temperature is higher than the set threshold temperature, the opening degree of the MEMS silicon valve is increased by a set value so as to reduce the load of the compressor.
Because the heat of the compressor can cause the life reduction and the performance reduction of the compressor if the heat is not removed, a threshold temperature can be preset, when the coil temperature of the compressor exceeds the threshold temperature, the heat of the compressor can be determined, protective measures need to be taken, at the moment, the opening degree of the MEMS silicon valve can be adjusted to be large, the flow rate of a refrigerant is increased, the power of the compressor can be reduced, and the load of the compressor is reduced.
The opening degree of the MEMS silicon valve can be adjusted to be larger than a set value according to the specific model of the MEMS silicon valve, for example: the MEMS silicon valve may be adjustable from off to on, or may be adjustable from a first opening value to a second opening value of the MEMS silicon valve, the first opening value and the second opening value differing by one, two, or more setting values. Because the response time of the MEMS silicon valve is less than 200 milliseconds from full opening to full closing, the process of adjusting the MEMS silicon valve is very quick and less than 200 milliseconds, the valve adjusting time in a cold-heat exchange system is prolonged, and the efficiency of changing the load of the compressor is improved.
Therefore, in the cold-heat exchange system equipment, the MEMS silicon valve is adopted to adjust the flow of the refrigerant, the MEMS silicon valve not only has the advantage of high valve opening and closing speed, but also can perform overheat protection on the compressor through the temperature controller, and the superheat degree oscillation time is short, and the system energy-saving effect is excellent.
In addition, the service life of the MEMS silicon valve can exceed 100 ten thousand times, and the MEMS silicon valve has extremely quick response time (less than or equal to 0.2S time), so that a cold-heat exchange system adopting the MMEMS valve silicon can save more than 30 percent of energy compared with a common electronic expansion valve.
Meanwhile, the MEMS silicon valve can be upgraded through remote monitoring, the temperature algorithm of a temperature controller in the MEMS silicon valve is updated in time, or other MEMS silicon valve control software is updated, so that the reaction speed of the MEMS silicon valve is guaranteed, the upgrading and updating of products are realized remotely, and the consumption of hardware is reduced.
Of course, in the embodiment of the present invention, when the current coil temperature is less than or equal to the set threshold temperature, the opening degree of the MEMS silicon valve is maintained. Thus, stable operation of the heat exchange system is maintained.
Because the MEMS silicon valve replaces the existing electronic valve for adjusting the refrigerant flow in the cold-heat exchange system, the MEMS silicon valve has the functions of adjusting the opening degree of the MEMS silicon valve according to at least one parameter of the temperature parameter, the environment temperature and humidity parameter and the working mode parameter carried in the received user instruction. Like this, guaranteed cold and heat exchange system's current function to, because MEMS silicon valve has the fast advantage of ooff valve, further improved cold and heat exchange system's reaction time, thereby also promoted cold and heat exchange system's efficiency, also improved user's experience.
Since the temperature controller in the MEMS silicon valve is used for overheat protection of the compressor, the temperature controller is turned off when it is determined that the compressor stops operating, and thus, the consumption of resources can be saved.
The following operational flows are grouped into specific embodiments to illustrate the methods provided by the embodiments of the present disclosure.
In this embodiment, the heat exchange system may be a heat pump system including a compressor, and a MEMS silicon valve may be used instead of the existing thermal expansion valve, and the temperature controller in the MEMS silicon valve is provided in the coil of the compressor.
Fig. 2 is a flowchart illustrating a control method of a heat exchange system according to an exemplary embodiment, where as shown in fig. 2, a process of the heat exchange system control includes:
step 201: the compressor of the heat pump system is started to operate.
Step 202: the temperature controller provided in the coil of the compressor starts to operate.
Step 203: and acquiring the current coil temperature of the coil in the compressor through the started temperature controller.
Here, the current coil temperature of the coil in the compressor may be periodically acquired to reduce the load.
Step 204: is it determined whether the current coil temperature is greater than the set threshold temperature? If so, go to step 205, otherwise, go to step 206.
Step 205: the opening of the MEMS silicon valve is adjusted by a set value and step 207 is performed.
If the MEMS silicon valve is closed, this step may open the MEMS silicon valve. If the opening degree of the MEMS silicon valve is smaller, the opening degree of the MEMS silicon valve can be adjusted to be larger, so that the flow of the refrigerant passing through the compressor is larger, the load of the compressor can be reduced, the temperature of the compressor is reduced, and the overheat protection of the compressor is realized.
Step 206: the opening of the MEMS silicon valve is maintained and the process returns to step 207.
If the MEMS silicon valve is still closed, if the MEMS silicon valve is at the first opening, the first opening is considered, and so on.
Step 207: is the compressor stopped? If yes, go to step 208, otherwise, go back to step 203.
Step 208: the temperature controller is turned off.
Therefore, in the embodiment, the MEMS silicon valve is adopted in the heat pump system to adjust the flow rate of the refrigerant, and the MEMS silicon valve not only has the advantage of high valve opening and closing speed, but also can perform overheat protection on the compressor through the temperature controller, and has short superheat oscillation time and excellent system energy saving effect.
