How Split Air Conditioning Enhances Indoor Air Quality through Ventilation
Split-type air conditioners are an ideal form of climate control for residential areas where only some rooms need to be cooled, as these units do not require an exhaust to vent the air itself. Rather than having a fan that moves air in and out of the room, the AC works by using a refrigerant that cycles between the evaporator and condenser. This causes the hot air inside the room to be cooled without any unwanted ventilation from the outside world.
However, even though split-type AC units are working without ventilation, there is still an important role in preventing mold and bacteria from entering the living space. The pipes and wiring that are used to move the refrigerant between the indoor and outdoor units can become dirty over time, encouraging the growth of microbes. Thus, it is important to keep the system regularly maintained, particularly in humid climates, by getting it serviced every now and then.
Since open windows in rooms cooled with split-type air condtioners are generally kept shut, it is also possible to add an air ventilation system to the AC unit. This can help bring fresh air from the outside into the living space, but it also comes with the risk of bacteria and mold being brought in along with it. For this reason, it is best to leave ventilating a split-type AC to experienced professionals, as the fan may not be able to run in unison with the added ventilation system.
In commercial buildings where many workers are inside, air ventilation systems are often added to the split air conditioners. Unfortunately, studies have linked the presence of these systems with increased occurrences of bacterial infections in the staff, such as sinus and bronchial infections. Therefore, while they may seem like a good idea in theory, the risks must also be taken into consideration.
In short, split air conditioners are an effective hot air cooling method that does not require typical ventilation. This makes them a great option for residential use. However, professionals must be consulted when looking to add an air ventilation system to the unit, as the risks need to be carefully weighed up. Additionally, regular upkeep and maintenance of the system, including some cleaning of the pipes and wiring, is vital to ensure that mold and other microbes don’t take advantage of any dirtiness in the system, which may lead to illnesses in the occupants.
