R22 refrigerant, also known as Chlorodifluoromethane, has been widely used in various cooling systems for decades. Although its production is being phased out due to environmental concerns, understanding its applicable working conditions remains crucial for existing systems. This refrigerant operates efficiently under specific temperature and pressure ranges, making it suitable for certain HVAC and refrigeration applications.

Key Working Conditions for R22 Refrigerant

• Temperature Range: R22 performs optimally in evaporator temperatures between -40°F to 60°F (-40°C to 15°C).
• Pressure Levels: The typical operating pressure for R22 ranges from 70 psi to 250 psi, depending on the system's design and ambient conditions.
• Compatibility: R22 works well with mineral oils and alkylbenzene lubricants, ensuring smooth compressor operation.

Applications of R22 Refrigerant

1. Residential and commercial air conditioning systems
2. Medium-temperature refrigeration units (e.g., supermarket display cases)
3. Heat pumps designed for moderate climates

Due to its ozone-depleting potential, R22 is being replaced by environmentally friendly alternatives. However, for legacy systems still in operation, maintaining proper working conditions ensures efficiency and longevity.
