A small split air conditioner is a type of air conditioning system that is ideal for smaller spaces. It is a two-part system, consisting of an indoor unit and an outdoor unit. The indoor unit is installed inside the room and the outdoor unit is installed outside the room. The two units are connected by copper pipes and electrical wiring. The indoor unit contains an evaporator coil, a fan, and a compressor. The outdoor unit contains a condenser coil, a fan, and a compressor. The indoor unit takes in the warm air from the room and passes it over the evaporator coil, which cools the air and sends it back into the room. The outdoor unit takes in the warm air from the indoor unit and passes it over the condenser coil, which releases the heat outside. This type of air conditioning system is perfect for smaller spaces because it is compact and efficient. It is also relatively inexpensive and easy to install.
