A DX split system is a type of air conditioning system that is composed of two separate components: an outdoor condenser and an indoor evaporator. The condenser is responsible for removing heat from the air, while the evaporator is responsible for cooling the air. The two components are connected by refrigerant lines, which allow the refrigerant to flow between the two units. This type of system is highly efficient and is often used in residential and commercial buildings. It is also often used in industrial settings, as it is able to cool large areas quickly and efficiently. The DX split system is an effective way to cool a building, as it can provide a comfortable temperature for occupants while also saving energy.
