Basic concept of mini split AC systems
Mini split AC systems, also known as ductless air conditioning systems, are a popular choice for cooling in both residential and commercial settings. Unlike traditional central air conditioning systems, mini split AC systems do not require ductwork to distribute cool air. Instead, they consist of two main components: an outdoor unit and one or more indoor units. The outdoor unit houses the compressor and condenser, while the indoor units deliver cooled air directly into the space. This allows for more flexibility in installation and zoning.
Components and operations of mini split AC systems
A mini split AC system typically consists of three main components: the outdoor unit, indoor unit(s), and the refrigerant lines that connect them. The outdoor unit contains the compressor, which is responsible for pressurizing and circulating the refrigerant. It also houses the condenser, which releases heat absorbed from the indoor air. The indoor unit(s), usually mounted on the wall or ceiling, contain the evaporator coil, fan, and air filters. The evaporator coil cools and dehumidifies the air, while the fan circulates it.
The operation of a mini split AC system involves the circulation of refrigerant between the outdoor and indoor units. The compressor in the outdoor unit pressurizes the refrigerant, which then flows through the refrigerant lines to the indoor unit(s). Inside the indoor unit(s), the refrigerant undergoes a heat exchange process, absorbing heat from the indoor air and releasing it outside. The cooled air is then distributed back into the space, creating a comfortable indoor environment.
