What is a key difference between high-pressure and low-pressure refrigerants?

High-pressure refrigerants indeed require different handling and equipment compared to low-pressure refrigerants. This distinction is crucial because the physical properties and behaviors of high-pressure refrigerants necessitate specialized equipment such as compressors, valves, and hoses that can withstand the greater pressures involved. Improper handling or equipment that is not rated for high pressure can lead to safety hazards, including leaks or ruptures.

Understanding this difference is particularly important for technicians who must adhere to safety standards and ensure that the systems they work with are compliant with both operational requirements and relevant regulations. This knowledge helps ensure the efficiency and reliability of refrigeration systems.

Conversely, low-pressure refrigerants do not inherently imply higher costs, lower freezing temperatures, or a greater environmental impact, which are considerations that may be context-dependent rather than directly related to the pressure classification.
