How to detect refrigerant leaks?

Refrigerant is an important and indispensable part of refrigeration equipment, and currently, the commonly used refrigerants include R454B, R290, R32, R410A, and other types, which are mainly used in domestic air conditioning, commercial air conditioning, central air conditioning, and a variety of refrigeration equipment. Among them, R410A and R32 are the refrigerants used in the United States and Japan, etc. R32 and R290, due to their flammable and explosive properties, are categorized as highly hazardous refrigerants; R410AGWP value is higher (2088), which produces a large amount of greenhouse gases, and it is considered to be only a transitional alternative. As people become more and more concerned about the atmospheric environment, air-conditioning manufacturers are becoming more and more cautious in their choice of refrigerants, and are turning to those with a lower Global Warming Potential (GWP).

Leakage of refrigerant will not only the environment but also the physical health and safety of life and property, as well as the normal operation of the refrigeration equipment system, leading to a decrease in the cooling effect and an increase in energy consumption and operating costs.

Therefore, it is very important to detect refrigerant leakage faults efficiently, scientifically, and professionally and take corresponding safeguard measures in time, and the Fosensor Refrigerant Sensor provides solutions for this.

Fosensor NDIR principle refrigerant sensor

With the development of technology, refrigerant leakage detection technology is also constantly upgraded, Fosensor launched a refrigerant gas leakage detection for the NDIR principle gas sensor FS4NDIR/R454B. Non-dispersive infrared gas detection technology is a new technology for refrigerant leakage detection and localization, it is selective. Long life, high sensitivity; it is the use of halogen gas to a specific wavelength of infrared light absorption principle 逬 line design when the measured gas into the infrared gas chamber will have a different degree of absorption of infrared light, so as to calculate the halogen gas content, for the precise location of the leak. The infrared sensor is characterized by good resistance to toxicity, wide range, sensitive response, etc. FS4NDIR/R454B is designed for air-conditioning systems using R32, R454A, R454B, and R454C refrigerants to monitor the leakage situation in real-time and provide timely alarms.

How to detect refrigerant leaks?

In addition to using a refrigerant sensor to detect refrigerant leaks, you can also check for refrigerant leaks yourself through the following methods

1. Visual inspection: Check the connecting pipes and refrigerant lines and fittings for obvious signs of damage such as oil stains, damage, rust, or cracks. Refrigerant leaks often have lubricating oil seepage, so visual inspection is a simple and direct detection method.

2. Soap and water detection: in the suspected leakage of parts coated with soapy water, if there is a refrigerant leakage, soapy water will be in the leakage of parts of the formation of air bubbles. This method is suitable for large leaks or in the pipeline outside the visible parts.
