A split system is one of the types of air conditioners that is designed for cooling and/or heating premises. An “On/Off” split system is a combination of two units: an external (compressor) and an internal (evaporator). Various types of freon gas are used as a cooling agent in split systems.
Most frequently, wall-mounted split systems are used to lower the air temperature in a room, but modern split systems also have the functions of heating, ventilation, and often dehumidification.
Thanks to its expansive functional capability, nowadays a split system is a household appliance that can be used to maintain ideal temperature settings in a room, regardless of what season it is.
