Air Conditioning Unit Cool the Air
The air conditioning system is an essential part of a comfortable home. It cools the air by evaporating and condensing water, and it removes moisture to control humidity. During this cooling process, it also filters out dirt and microorganisms that may have collected in the home.
Basically, an air conditioning works by using two units: an outdoor unit that is installed on the ground or up against the house wall and an indoor unit that houses the evaporator coil and fan to circulate the cooled air. Refrigerant lines connect the two units and cycle refrigerant between them to complete the cooling process.
Before air conditioning became commonplace, people cooled their homes with blocks of ice. The first air conditioning unit was invented in 1902 by a man named Willis Haviland Carrier. His invention helped to revolutionize the way we live. It changed architecture, allowed people to live without windows and even made it possible to settle in areas that would be uninhabitable during hot seasons.
How Does an Air Conditioning Unit Cool the Air?
Air conditioning is a complex system, but it’s easy to understand how it cools the air. The process starts with a thermostat sensor detecting the desired temperature, which it sends a signal to the compressor to begin the cooling cycle. The air conditioning system’s fans then come on to help distribute the cooled air throughout the house, usually through ductwork that blows the air to different rooms.
During the cooling process, the cold liquid refrigerant in your home’s evaporator coil absorbs heat from the air. This causes the refrigerant to change from a liquid to a gas. As a result, it releases its heat into the air outside through the condenser coils. Powerful fans help the process along by blowing the outdoor unit’s condenser coils to make it quicker and more effective.
Once the refrigerant has cooled down in the condenser coils, it goes back into the compressor. Here the refrigerant gets compressed to a high temperature, and its heat is transferred to the surrounding air. This heat is then dissipated in the outdoor environment, and the liquid refrigerant returns to the evaporator coils for the next cooling cycle.
The history of air conditioning traces back to ancient civilizations’ rudimentary methods of cooling, such as using hand fans, evaporative cooling techniques, and architecture designed to maximize airflow. However, it wasn’t until the late 19th century that modern air conditioning began to take shape with the pioneering work of inventors like Willis Carrier. Carrier’s invention of the first modern electrical air conditioning unit in 1902 laid the foundation for a transformative technology that would reshape human habitation patterns worldwide.
The evaporator coils are important to keep clean to ensure the efficient performance of the air conditioning system. If the evaporator coils become dirty, the air flow will be disrupted and the entire system could suffer from a lack of proper circulation. This is why it’s a good idea to regularly replace the air filter to prevent buildup of harmful particles in the evaporator coils and other components of the air conditioning system.
