Which refrigerant is typically classified as high-pressure?

R-22 is classified as a high-pressure refrigerant. This classification is important in refrigerant applications because it determines the design and material specifications of the components used in refrigeration systems. R-22 operates at higher pressure levels compared to many other refrigerants, leading to higher system pressures during operation.

This aspect is significant for technicians because working with high-pressure refrigerants requires specific safety precautions and tools rated for those pressures. Understanding the characteristics of refrigerants like R-22 is crucial for effective system diagnosis and repair, ensuring that installations meet safety regulations and perform effectively.

While R-404A, R-134A, and R-12 also have their own pressure classifications and characteristics, R-22 is distinctly known for its higher operating pressures in comparison, impacting its applications and the handling protocols required in service situations.
