R32, also known as difluoromethane or carbon difluoride, is a colorless and odorless refrigerant. It belongs to the family of fluorocarbon replacements for ozone-depleting substances like Freon. R32 exhibits excellent thermodynamic properties, making it a popular choice for refrigeration applications.
Key features of R32 include its low boiling point, vapor pressure, and operating pressure, along with its high refrigeration coefficient. An important aspect to note is that R32 has a zero ozone depletion potential, meaning it does not contribute to the destruction of the ozone layer. Additionally, it has a relatively low global warming potential.
Through comparative analysis of experimental results, it is found that R32 is relatively safe in terms of flammability and is difficult to burn unless it encounters an open flame. Even if the internal components of the air conditioner fail to cause local overheating, it is difficult to burn or explode. Moreover, the price of R32 is lower than that of R410A, and the air-conditioning displacement using R32 is smaller. Therefore, R32 has broad application prospects in the air-conditioning manufacturing industry. With the development of the air-conditioning manufacturing industry, R410A and R22 will gradually be replaced by R32.
