In mini-split style systems, the refrigerant lines are typically connected using what type of fittings?

• A. Welded fittings
• B. Compression fittings
• C. Flare fittings
• D. Threaded fittings

Answer: (C)

In mini-split style systems, the refrigerant lines are typically connected using flare fittings because they provide a reliable and leak-free connection for refrigerant lines. Flare fittings are designed to create a tight seal by having the copper tubing flared at the end, which allows for a large sealing surface area when the fitting is tightened. This type of connection is particularly advantageous in mini-split systems, which are common in residential and commercial air conditioning installations. The ability to easily disconnect and reconnect the refrigerant lines is crucial for servicing and maintaining these systems, and flare fittings facilitate this without compromising the integrity of the refrigerant circuit. Additionally, flare fittings are designed to handle the pressures associated with refrigerants, making them suitable for the demands of HVAC applications. They are less susceptible to leaks compared to other fitting types if properly installed, thus ensuring the longevity and efficiency of the system.
