Technical Comparison of Semiconductor (Metal Oxide) vs. Infrared (NDIR) Refrigerant Sensors
| Funkcija | Semiconductor (Metal Oxide) Sensors | Infrared (NDIR) Sensors |
|---|---|---|
| Darbo principas | React to refrigerant gas by altering the conductivity of a metal oxide surface. | Use Non-Dispersive Infrared (NDIR) absorption to detect specific gas wavelengths. |
| Argumentai "už" | – Cost-effective – Compact design – Quick response to basic gas detection | – High accuracy – Long operational life – Specific to target refrigerants (low cross-sensitivity) |
| Minusai | – Susceptible to cross-sensitivity (false readings from other gases) – Affected by humidity | – Higher initial cost – Slower response time – Larger physical footprint |
| Ideal For | Budget-sensitive applications, simple leakage alarms, or non-critical environments | Precision-driven systems, industrial monitoring, or applications requiring high reliability |
Applications of Refrigerant Sensors
Commercial Air Conditioning
Viešbučiuose, prekybos centruose, biurų pastatuose ir oro uostuose aušalo nuotėkio aptikimas yra būtinas norint išvengti sistemos gedimų ir apsaugoti keleivius.
Cold Storage and Supermarkets
Norint išlaikyti gaminio vientisumą ir sumažinti šaltnešio nuostolius, reikia aptikti nuotėkį šaldytuve, šaldymo kamerose ir šaldikliuose.
Data Centers
Serverių patalpos labai priklauso nuo ŠVOK sistemų. Dėl nuotėkio gali pakilti temperatūra ir sugesti įranga.
Vehicle HVAC Systems
Elektrinės ir hibridinės transporto priemonės, naudojančios R-1234yf arba R-744, turi stebėti keleivių saugumą.
Industrial Refrigeration
Didelės apimties sistemoms, naudojančioms amoniaką arba CO₂, reikia pažangių jutiklių, kad būtų laikomasi griežtų saugos reikalavimų.
Chiller and Boiler Rooms
Dėl nedidelių nuotėkių uždarose mechaninėse patalpose gali susidaryti pavojinga koncentracija. Detektoriai dažnai yra integruoti su ventiliacija ir signalizacija.

Frequently Asked Questions (FAQs) about Refrigerant Sensors
1. What is a refrigerant sensor?
A refrigerant sensor is a device used to detect the presence and concentration of refrigerant gases in systems such as HVAC, refrigeration units, and automotive air conditioning. It plays a vital role in ensuring safety, efficiency, and environmental compliance by identifying leaks or abnormal gas levels.
Šaltnešio jutiklis: principai, taikymas ir svarba šiuolaikinėse sistemose
2. How does a refrigerant sensor work?
Refrigerant sensors detect gases using technologies such as infrared (IR) absorption, electrochemical reactions, semiconductor conductivity, or photoacoustic effects. Each method identifies refrigerant gases by measuring specific physical or chemical changes caused by their presence.
3. Why are refrigerant sensors important?
Refrigerant sensors are essential for maintaining safety by detecting leaks that can be hazardous or flammable. They also ensure system efficiency by monitoring refrigerant levels and help meet environmental regulations by preventing harmful gas emissions.
4. Where are refrigerant sensors commonly used?
These sensors are used in a variety of applications, including HVAC systems, commercial and industrial refrigeration, automotive air conditioning, and environmental monitoring systems. They are also found in areas where refrigerant leaks could pose health or safety risks.
5. How often should a refrigerant sensor be calibrated?
Most refrigerant sensors should be calibrated at least once a year. However, calibration frequency may increase depending on environmental conditions, regulatory requirements, or the critical nature of the application.
6. What are signs of a failing refrigerant pressure sensor?
Common signs include warm air from air conditioning vents, erratic system behavior, frequent compressor shutdowns, and warning lights on the control panel. These symptoms suggest the sensor may not be accurately detecting pressure or gas levels.
7. Can I test a refrigerant pressure sensor myself?
Yes, testing can be done using tools like a multimeter, pressure gauges, or diagnostic scanners. However, due to the technical nature of HVAC systems, it’s often recommended to have a professional perform diagnostics to ensure accurate results and safe handling.
8. How long does a refrigerant sensor typically last?
The lifespan of a refrigerant sensor varies depending on the operating environment and maintenance practices. Under normal conditions and with regular servicing, a sensor can last several years. Harsh or corrosive environments may reduce its lifespan.
9. What maintenance is required for refrigerant sensors?
Regular inspection, cleaning, and calibration are the main maintenance tasks. It’s also important to keep the sensor dry, avoid physical damage, and replace it promptly if it shows signs of malfunction or inaccuracy.
10. Are refrigerant sensors required by law or regulations?
Yes, in many regions, standards such as EN 378 in Europe and ASHRAE 15 in the United States require refrigerant leak detection for safety and environmental protection. Compliance with these regulations often mandates the use of reliable and properly calibrated refrigerant sensors.
