When discussing refrigeration systems, it's important to clarify that Apple products like iPhones or iPads do not use refrigerants such as R22. However, if you're referring to screen sizes for Apple devices in the context of refrigeration equipment displays (e.g., control panels), here's a technical overview with refrigerant-related insights:

Understanding Screen Size Requirements for Refrigeration Interfaces

Modern refrigeration systems often incorporate digital displays for monitoring parameters like:

• Refrigerant pressure levels (R22 systems typically operate at 68-250 psi)
• Temperature readings (R22 evaporates at -40.8°F at atmospheric pressure)
• System diagnostics (especially important for phased-out R22 systems)

Typical Display Specifications for Refrigeration Controls

1. Compact displays (3.5"-5"): Common for basic R22 monitoring systems

2. Mid-range displays (7"-10"): Used in commercial R22 refrigeration units

3. Large industrial interfaces (15"+): For complex HVAC systems still running R22

Note: Since R22 was phased out in 2020 under the EPA's Clean Air Act, most new displays now show alternative refrigerants like R407C or R410A. When working with older R22 systems, proper screen visibility is crucial for monitoring this ozone-depleting substance.
