Split

A split unit air conditioner is an air conditioning system that consists out of two separate units; the water or air-cooled condensing unit and the air handling unit. The air handling unit is installed in the air conditioned room itself, whereas the condensing unit is installed either in the engine room or other mechanical space. The condensing unit can be mounted outside as well. The two units are connected by insulated refrigerant lines. The compressor and the condenser are placed in the condensing unit. The evaporator coil is placed in the evaporating unit. As the condensing unit isn’t placed inside the conditioned area, the split unit air conditioner system is a lot more quiet.
