As the refrigeration technology becomes more and more mature, air conditioners have a variety of selective refrigeration methods and refrigerants, but currently the most common and widely used in the air conditioning market is vapor compression refrigeration. This cooling method has a strong cooling effect and is very popular. However, it is worth noting that because the vapor compression refrigerant is prone to high pressure during use, it is easy to cause leakage of the refrigeration equipment pipeline. Therefore, the safety during use has become the focus of attention.

In the "Montreal Protocol", the use of chlorofluorocarbons (CFCs) for depleting the ozone layer has been banned.

■ Hydrochlorofluorocarbons are referred to as HCFC, including R22, R123, R141b, R142b and other ozone layer destruction factors, which are only a few percent of R11. Therefore, HCFC substances are regarded as the most important transitional substitutes for CFC substances. R22 is scheduled to be phased out in 2020, R123 is scheduled to be phased out in 2030, and developing countries can postpone it for 10 years.

■ Hydrofluorocarbons are referred to as HFCs, mainly including R134a, R125, R32, R407c, R410a, R152, etc. The ozone layer destruction coefficient is 0, but the climate warming potential value is very high. The "Montreal Protocol" does not stipulate its trial period, but it is classified as a greenhouse gas in the "United Nations Framework Convention on Climate Change" Kyoto Protocol.

Ozone depletion potential, climate warming potential, safety, including flammability and toxicity, have become the three primary considerations for refrigerant selection.



Refrigerant leakage is a kind of failure of air-conditioning refrigeration system and unit. The leakage of refrigerant will bring a series of adverse effects to the normal operation of refrigeration equipment, and bring a lot of inconvenience to operation and maintenance. For example, leakage into the unit will cause the unit to Deterioration of performance and reduction of cooling capacity; external leakage will pollute the air environment, endanger personal safety, and affect the performance of the unit.

At present, the most common refrigerant leak detection methods are the visual leak detection method and the soapy water leak detection method. Therefore, it is particularly important to find leakage cause accurately, quickly, scientifically and professionally and take corresponding safeguard measures in time to reduce the losses caused by leakage.

 

Zhengzhou Winsen Electronics now introduces a flat semiconductor principle gas sensor MP510C for refrigerant gas leakage detection.

Introduction to the working principle of MP510C sensor
The MP510C Freon gas sensor uses a multilayer thick film manufacturing process to fabricate heating and measuring electrodes and a metal oxide semiconductor gas-sensitive layer on a miniature Al2O3 ceramic substrate, and encapsulate it in a metal casing. The product has good anti-interference ability against common gases such as alcohol and acetic acid in usage scenarios. Popular used for leak detection of refrigerants in air conditioning and refrigeration systems.
