HVAC - EPA Certification Practice Exam

A split air conditioning system is characterized by having both an indoor unit and an outdoor unit, making it distinct from other types of systems. The indoor unit, typically installed within the living space, is responsible for distributing cooled air throughout the environment. The outdoor unit contains the compressor and condenser, which are crucial for removing heat from the refrigerant and expelling it outside. This setup allows for more efficient cooling and is generally quieter indoors compared to window or portable systems, which operate as single units. Central systems also involve components in both indoor and outdoor locations, but they utilize ductwork to distribute air throughout multiple rooms, which is a different operational approach compared to a split system.
