A small split system air conditioner is a type of air conditioning system that is designed to provide cooling to a single room or area. It consists of two main components: an outdoor unit and an indoor unit. The outdoor unit contains the compressor, condenser, and expansion valve, while the indoor unit contains the evaporator and fan. The two units are connected by refrigerant lines and electrical wiring. The outdoor unit is usually installed outside the building, while the indoor unit is installed inside the room or area to be cooled. The small split system air conditioner is a great choice for those who need to cool a single room or area without having to install a full-sized central air conditioning system. It is relatively easy to install and maintain, and is more energy efficient than a window unit. It also provides more precise temperature control than a window unit, making it a great choice for those who need to maintain a specific temperature in a single room or area.
