Understanding the terminology
What is a Mini Split AC?
A Mini Split AC, also known as a ductless air conditioning system, is a type of air conditioner that does not require ductwork to distribute air throughout the space. It consists of two main components: an indoor unit and an outdoor unit. The indoor unit is mounted on a wall or ceiling and is responsible for cooling the room, while the outdoor unit houses the compressor and condenser.
What is a Central AC?
On the other hand, a Central AC is a traditional air conditioning system that uses ducts to cool multiple rooms or an entire building. It typically consists of a central unit that is connected to a network of ducts, which deliver cool air to each room through vents. Central AC systems are usually found in larger homes or commercial buildings.
The anatomy of Mini Split and Central AC
Basic components of a Mini Split AC
A Mini Split AC is composed of several key components. The indoor unit contains a fan, evaporator coil, and air filters. The outdoor unit houses the compressor, condenser coil, and expansion valve. The two units are connected by refrigerant lines, which allow the transfer of heat from indoors to outdoors. Additionally, a remote control is provided to adjust the temperature and settings of the Mini Split AC system.
Basic components of a Central AC
In contrast, a Central AC system consists of a central unit, air ducts, vents, and registers. The central unit contains the compressor, condenser coil, and evaporator coil, along with a blower fan. The ducts serve as pathways for the cool air to travel to different rooms, while the vents and registers allow for the adjustable flow of air into each space. A thermostat is typically used to control the temperature and settings of the Central AC system.
The operation modes of both systems
How a Mini Split AC works
A Mini Split AC operates by absorbing heat from the indoor air and releasing it outside. The indoor unit blows warm air over the cold evaporator coil, which cools the air. The cooled air is then circulated back into the room, while the absorbed heat is transported through the refrigerant lines to the outdoor unit. The outdoor unit removes the heat from the refrigerant and releases it outside, allowing the cycle to continue. This process enables the Mini Split AC to cool the room efficiently.
How a Central AC works
Similarly, a Central AC system works by cooling the indoor air and removing heat from the space. The central unit compresses and condenses refrigerant to cool it. The cool refrigerant flows through the evaporator coil, where it absorbs heat from the indoor air. The cooled air is then distributed through the ducts to each room. The absorbed heat is expelled outside through the condenser coil, completing the cooling cycle. This continuous process ensures that the Central AC system maintains a comfortable indoor temperature.
Comparing installation processes
