Air conditioning is one of the most important inventions in modern history. It allows people to live in places with high temperatures and still feel comfortable indoors. It can also improve indoor air quality by removing humidity and dust. Air conditioners were first developed by Willis Carrier to reduce humidity at a Brooklyn printing company in 1902. They were not widely used until the 1950s, when they became popular in cars and residential homes.
Air conditioners work by cooling the temperature of a room or building through a process of evaporation and condensation. This is accomplished by using chemicals that convert from a liquid to a gas and then back again quickly, which cools the air. These chemicals are housed in a compressor which is located outside of the home. A fan blows air over these coils, transferring heat from the air to the refrigerant and then pushing it outdoors.
The air that is cooled is then circulated throughout the house or business with ductwork. This helps to distribute the cooled air evenly and keep the temperature at a desirable level. The size of the air conditioner will determine how much heat it can remove, which is measured in British thermal units (BTUs). The amount of BTUs needed will vary based on the ceiling height, number and type of windows and doors, insulation and how sunny the area gets, but you can find the basic basics by doing some simple math.
A central AC is more efficient than a portable unit and can cool multiple rooms at once. It uses a split system that has a cooling compressor housed indoors and a fan housed outdoors, with ductwork delivering the cool air throughout the house or business.
There are many different brands and models of air conditioners. It’s best to research your options and find a model that fits your budget, needs and lifestyle. If you have any questions about the best air conditioning to buy, contact a qualified sales professional.
An ENERGY STAR certified air conditioner will help you save money on your energy bills and reduce your impact on the environment. The Trane XV20i, for example, features a variable speed fan and compressor sound insulator to keep it running quietly.
When choosing an air conditioning unit, look for a SEER rating of at least 13. The higher the SEER, the more efficient the air conditioner will be. SEER ratings are calculated over the course of a cooling season and take into account a variety of factors, including indoor temperature fluctuations and varying outdoor temperatures. This information is available on the manufacturer’s website, so you can make an informed decision about which air conditioner will be right for your home or business. A professional can assist you with making this choice.
