Why You Need An Air Conditioning System
Air conditioning, heating, and air conditioning systems are the major technology of vehicular and indoor environmental conditioning. It is a device that controls the temperature by removing external air from the environment and replacing it with indoor air. Its objective is to give acceptable indoor air quality and thermal comfort.

Conventional central air conditioning system involves a two-stage air conditioning system that uses a heat-water combination for the oxidation of liquid refrigerant gas. The second stage is often referred as the “regenerative cooling” stage because the system continually heats and cools the indoor air to maintain the desired temperature. The regenerative cooling stage, however, can only stabilize the indoor air cool temperature. In some application, such as in the water system, the system uses a phase change refrigerant gas instead of water. The third stage, which is often referred as the “storage” stage, is similar to a closed loop.
Modern air conditioners can be built based on several different techniques such as the chilled water method or evaporative cooling and the chilled air method. The first is considered more energy efficient although the second has more cooling effect than the first one. One of the latest developments in air conditioning field is the use of energy recovery ventilators or “exhaust excluders”. This kind of air conditioner collects the warm outside air, condenses it, and releases it into living spaces. In some advanced models, the exhaust excluder also works as a ventilation for the heating system.
Air conditioners are used to cool down the temperature in a specific room or area. The temperature is controlled either manually or automatically depending upon the need. If the temperature is extremely cold, air conditioning units can be used inside the house to maintain the ideal room temperature or cool it slightly. But in hot, humid regions, air conditioning units are used to set the room temperature to remain comfortable. Similarly, to attain even temperatures inside a house, air conditioning unit can be used to distribute the cool outside air through ducts and other outlets.
If the outside temperature is extremely hot, air conditioners can be used for dehumidification. By this process, excess humidity is collected and sent back outside as cool air. This type of conditioning is very useful to cleanse indoor air of pollutants, dirt, mold, bacteria, and fungi. Some of the common pollutants that are collected by this process are pollen, mold spores, dust mites, smoke, pet dander, smoke, and moisture.
Air conditioners have many more features and you can find the best one according to your individual needs. Usually, you will have to make some decisions on the size of the evaporator coil, the cooling capacity, power requirements, and the number of fans. However, these factors are only basic and you can choose the best AC system that suits your needs. As mentioned earlier, AC systems are now available in various designs so if you want something that looks unique, you can check out the various options available in the market today.
