Direct Expansion (DX) Split System
This type of system is best suited where there is little room for supply and return ductwork and/or where it is difficult to penetrate either a roof or wall for ductwork. Typical application examples are retail spaces, conference rooms and spaces on a first floor or basement. By allowing refrigerant to be piped remotely from the condenser to the air handler (fan coil), the equipment can be located at considerable distances away from an outside wall or roof area. Special considerations must be made to properly size the refrigerant piping to ensure proper part-load control.
This system requires the following components:
- Condensing Unit(s)
- Fan-Coil Air Handler(s)
- Refrigerant Piping and Accessories
- Controls
