An air conditioning system is a system that is designed to regulate the temperature, humidity, and air quality of a space. It works by using a combination of mechanical and electrical components to control the air temperature and humidity in a room or building. The most common type of air conditioning system is the split system, which consists of an indoor unit and an outdoor unit. The indoor unit is responsible for cooling the air, while the outdoor unit is responsible for circulating the cooled air throughout the space. The air conditioning system also helps to filter out airborne particles, such as dust, pollen, and other allergens, which can help to improve the air quality in the space. Additionally, the air conditioning system can also help to reduce energy costs by regulating the temperature of the space.
