Split System

A split system is a type of heating, ventilation, and air conditioning (HVAC) system commonly used in residential and commercial buildings.  It consists of two main components:

• Indoor Unit  -  This component is installed inside the building and typically contains the evaporator coil, which cools and dehumidifies the air.
• Outdoor Unit  -  This component is installed outside the building and houses the compressor, condenser coil, and fan.  The compressor compresses the refrigerant, and the condenser coil releases heat from the refrigerant to the outside air.

In a split system, the indoor and outdoor units are connected by refrigerant lines, which circulate refrigerant between the two units.  The refrigerant absorbs heat from indoor air as it passes through the indoor unit's evaporator coil, then carries that heat to the outdoor unit where it is released to the outside air.

Split systems are popular because they are efficient, quiet, and provide good control over indoor temperatures.  They are often used in buildings where central air conditioning systems are impractical or too costly to install. Split systems can also be used for heating, cooling, or both, depending on the configuration and type of system.
