Description
Technical field:
The present invention relates to a kind of refrigeration system filth blockage detection device, belong to the sensor detecting device technical field.
Background technology:
Be easy to cause foul to stop up when containing impurity in the refrigeration system, the refrigerant cycle in this moment refrigeration system is not smooth, influences refrigeration, stops up even not freeze when serious.Refrigeration system generally can be blocked in throttling element and filtrator etc. and locate, and judges that in the past stopping up is by simple temperature with feel feel refrigeration device, observes the refrigeration system high-low pressure, then utilizes experience or exclusive method to wait and determines whether it is dirty stifled.This determination methods is being stopped up when not serious, and the refrigeration system device temperature difference is not obvious, stops up refrigeration system pressure influence little the time, is difficult to judge whether refrigeration system is stopped up.
Summary of the invention
Goal of the invention:
The objective of the invention is to defective, a kind of refrigeration system filth blockage detection device is provided at the above-mentioned background technology.
Technical scheme:
The present invention adopts following technical scheme for achieving the above object:
A kind of refrigeration system filth blockage detection device comprises first temperature sensor, second temperature sensor, one-chip computer module, power module, reset circuit module, clock circuit module, sound prompting device, display module; Wherein the output terminal of first temperature sensor, second temperature sensor is connected with one-chip computer module respectively, reset circuit module, clock circuit module are connected with one-chip computer module respectively, one-chip computer module is connected with the input end of sound prompting device, the input end of display module respectively, and power module is imported power supply to one-chip computer module.
The sound prompting device is a hummer in the refrigeration system filth blockage detection device of the present invention.
Display module is a LCD display in the refrigeration system filth blockage detection device of the present invention.
Beneficial effect:
The present invention does not need to utilize experience just can judge without other operational factors of association with refrigeration system, and swift with judgement, the accuracy rate height.Pick-up unit of the present invention when there is smaller obstruction in refrigeration system, adopts this device also can detect than fine many with hand, and effect is especially outstanding.
Description of drawings:
Fig. 1 is a refrigeration system filth blockage detection device internal circuit block diagram.
Fig. 2 is that pick-up unit of the present invention uses synoptic diagram.
Among the figure 9, the refrigeration system filth blockage detection device case; 10, display screen; 11, first temperature sensor and connection lead thereof; 12, second temperature sensor and connection lead thereof; 13, refrigeration system is suspected blocking portion; 14, the clip of temperature sensor.
Specific embodiments:
Be described in further detail below in conjunction with the enforcement of accompanying drawing technical scheme:
As shown in Figure 1, a kind of refrigeration system filth blockage detection device comprises first temperature sensor, second temperature sensor, one-chip computer module, power module, reset circuit module, clock circuit module, sound prompting device, display module; Wherein the output terminal of first temperature sensor, second temperature sensor is connected with one-chip computer module respectively, reset circuit module, clock circuit module are connected with one-chip computer module respectively, one-chip computer module is connected with the input end of sound prompting device, the input end of display module respectively, and power module is imported power supply to one-chip computer module.
The sound prompting device is a hummer in the refrigeration system filth blockage detection device of the present invention.
Display module is a LCD display in the refrigeration system filth blockage detection device of the present invention.
A kind of refrigeration system filth blockage detection device that is used for detecting of the present invention, directly detect the temperature difference of obstruction place with suspicion front and back, and in output display screen, show this temperature and temperature difference, when obstruction place temperature difference is spent greater than 2, the hummer of pick-up unit will send " ticking " and be interrupted sound, points out this place that obstruction is arranged, when obstruction place temperature difference is spent greater than 10, the hummer of pick-up unit will send that " the lasting sound that ticks-------", it is serious to point out this place to stop up.
Principle of work of the present invention is: there is the throttling phenomenon in refrigeration system obstruction place, and cold-producing medium can part evaporate after throttling, makes that refrigeration system obstruction place front and back temperature is inconsistent, be that temperature difference is arranged before and after the throttling, and this temperature difference is big more, illustrates that throttling is obvious more, just stops up serious more.This device is exactly a temperature difference of measuring obstruction place front and back, and judges whether refrigeration system is stopped up, the order of severity of obstruction according to the temperature extent.
This device is made up of one-chip computer module, clock circuit module, output display circuit module, reset circuit module, hummer output circuit module, the first temperature sensor input circuit module, the second temperature sensor input circuit module, power circuit module etc.One-chip computer module writes the program of temperature detection, computing, demonstration output and hummer output by above-mentioned requirements.After having made up power supply, clock and reset circuit, one-chip computer module just can have been worked.
As shown in Figure 2, in the real work of this pick-up unit, first temperature sensor, second temperature sensor be attached to respectively in the refrigeration system suspect the front and back end that obstruction is arranged, measure its temperature respectively and be sent in the one-chip computer module, in one-chip computer module, analyze relatively, calculate temperature difference, and then be sent to displays temperature and temperature difference in the LCD display, when temperature difference was spent less than 2, hummer did not send sound; When comparing temperature difference when spending less than 10 greater than 2 degree, then one-chip computer module sends steering order, and the control hummer sends " ticking " and is interrupted sound, points out this place that obstruction is arranged; When obstruction place temperature difference was spent greater than 10, then one-chip computer module sent steering order, and the control hummer will send the lasting sound of " tick-------tick ", pointed out this place to stop up seriously.
Process of the invention process: first temperature sensor is with second temperature sensor and be connected lead and stretch out the refrigeration system filth blockage detection device case, and temperature sensor is welded on good copper of heat conduction or the aluminium flake, and is attached to the inside surface of the clip of temperature sensor.When needing to detect, the clip of two temperature sensors is clipped in the place that refrigeration system might be stopped up respectively, (easily blocking up place etc.) as joint is arranged in device for drying and filtering front and back end, kapillary leading portion or the construction, observe temperature displayed and temperature difference in the display screen, listen attentively to the sound that whether has hummer to send, hummer sends " ticking " and is interrupted sound, and explanation place has obstruction; Hummer will send that " the lasting sound that ticks-------" illustrates that this place stops up serious.
