When heat exchange occurs directly between the ambient air and the evaporator of the refrigeration circuit we call the direct expansion system.
Direct expansion systems are commonly referred to by the type of air conditioner used. The most common systems used are:
• Window Appliance
• Split environment system
• Self-contained with remote condenser
• Self-contained with built-in condenser
• Self-contained with water condensation
• Split System for Duct
• Roof top
• Variable refrigerant flow system - VRF
