With the global awareness of environmental protection increasing, traditional non-flammable (A1) Freon refrigerants are gradually being phased out due to their significant impact on climate warming. To address this challenge, mildly flammable (A2L) refrigerants emerged, offering lower Global Warming Potential (GWP) values and becoming ideal alternatives to Freon. However, the use of mildly flammable refrigerants also brings new safety concerns, as leaks may lead to fires. Therefore, developing gas sensor technology suitable for detecting mildly flammable refrigerants is particularly important.

Among various gas detection technologies, semiconductor gas sensors and Non-Dispersive Infrared (NDIR) gas sensors are two methods more suitable for detecting mildly flammable refrigerants. NDIR gas sensors are widely used in large-scale cold storage warehouses and refrigeration equipment due to their high selectivity and detection accuracy. However, their high cost and large size limit their use in broader scenarios. In contrast, although semiconductor gas sensors are susceptible to interference from other gases in terms of selectivity, their compact size, low cost, and long service life make them an ideal choice for detecting leaks of mildly flammable refrigerants in household and commercial air conditioners.

Particularly noteworthy is the FCM2630 gas sensor module, which employs unique filtering technology to effectively reduce the impact of interfering gases such as alcohol, thus lowering false alarm rates. Additionally, FCM2630 exhibits excellent shock and mechanical impact resistance, maintaining stable performance in complex environments. Furthermore, the built-in temperature compensation circuit minimizes the influence of ambient temperature changes on detection results, enabling FCM2630 to provide accurate detection data under varying environmental conditions.

For the mildly flammable refrigerant R-32, the FCM2630 module has been calibrated for alarm points and set with optimized alarm concentration values. This means that air conditioning equipment manufacturers do not need to design temperature compensation circuits or calibrate alarm points themselves; they can simply install the FCM2630 sensor module on air conditioning equipment to easily achieve leak detection of mildly flammable refrigerants. This not only simplifies the production process but also enhances product safety and reliability.

To meet the needs of different customers, FCM2630 offers two models of gas sensor modules. The FCM2630-C01 features an analog signal output mode, offering a simple structure and cost-effectiveness. The FCM2630-J0A, on the other hand, not only provides alarm signal output but also includes high-performance features such as digital output monitoring signals and fault signals. Both models comply with the Japan Refrigeration and Air Conditioning Industry Association (JRA) standards and the International Electrotechnical Commission (IEC) standards, ensuring product quality and reliability.

In summary, with its unique technical advantages and broad application prospects, the FCM2630 gas sensor module has vast market potential and development opportunities in the field of detecting mildly flammable refrigerants. As mildly flammable refrigerants become more widely used and gas sensor technology continues to advance, FCM2630 is expected to provide even stronger safeguards for the safe use of air conditioning and refrigeration equipment.
