Explosion Proof Split System Air Conditioner

How is a Split System different from a Package System

Split systems have two separate components, an indoor (evaporator) unit and an outdoor (condensing) section connected by a “line set” or refrigerant lines .  The evaporator section is the part that goes inside the area that will be conditioned.  The condensing unit goes on the exterior, or outside.  Electricity and refrigerant lines must connect the two.

Split Systems provide the greatest flexibility for installation and interior spaces. Evaporators can be hidden in a ceiling, or behind a fake wall and have duct work run to multiple points . Split systems are also able to have up to 16 heads (evaporator sections) connected to one condenser section creating ability to have multiple heating and cooling zones in building with multiple rooms each with their own thermostat and set point.

Split systems are more complicated than a Wall, pad or roof top unit do to the additional refrigeration line sets, electrical and plumbing (for condensation).  Also because they are only connect to the outside by a refrigerant line, ventilation is not possible

Mini-splits don’t get all the coatings and accessories a wall mount or roof top unit might need. Units come in a plastic housing and galvanized steel frame.   Interior and exterior coils can be coated for corrosive environments.  The galvanized steel frame can be coated if need be or it can be switched out all together to a stainless steel.   All split systems can be manufactured to general purpose or hazardous location standards.

  • A split air conditioner is composed of two separate units, a condensing unit and an evaporative coil. It is from these two separate units that a split air conditioner gets its name. These units are joined by a set of copper tubing known as a “line-set,” which transfers refrigerant from one unit to another. The condensing unit, or condenser, is the part of a split air conditioning system that is located outside.
    • Pros:Â
      • Can be very effecient
      • can be placed in many different locations
      • can be easy to fix and maintain
      • typically quieter
    • Cons
      • Evaporator sections can be difficult to work on if hidden in ceiling spaces.Â
