Air conditioning, heating, and air conditioning are basically the technology of vehicular and indoor environmental comfort. Its aim is to give acceptable indoor air quality and thermal comfort to the occupants of a building. The various types of air conditioning systems are split into three categories: centralized air conditioning (also known as central air conditioners or appliances), remote controlled air conditioning, and portable air conditioning units. There are also many specific types of units such as Recuperator Heating System, Dehumidifier, and Heat Exchanger that have been specifically engineered for specific applications.

The most common type of air conditioners is a centralized unit that can either be an oil-fired or oil-less compressor:

It is usually mounted on the wall near the furnace or boiler room. The air conditioner compressor converts heat into mechanical energy that can be transferred to the air by a refrigerant. The compressors are often powered by electricity, but can also be fueled by oil. The compressor is then linked to a condenser, which cools and condenses the refrigerant gas.

In contrast, a remote controlled air-conditioning system can be installed without having to mount it on the wall. Instead, these units can be mounted on an air conditioning unit that moves with the movement of the unit. As the air cools, it passes through a heat exchanger that causes the liquid refrigerant to turn into a gas, which then enters the condenser. The condenser heats and then circulates the cooled gas through the house.

Air Conditioners: 

Oil-fired and oil-less air conditioners generally utilize an oil-fired or oil-less compressor that utilizes ductwork to move air throughout the entire cooling system. Unlike centralized units, oil-fired and oil-less compressors are not connected to ductwork. Instead, the air is moved through a number of pipes that lead to the air conditioner compressor. These pipes are usually placed along the outside perimeter of the house. Oil-fired and oil-less compressors are often cheaper to run than centralized units.

Central air conditioning systems are designed to keep a comfortable temperature for an entire home. They can use one of two different types of cooling methods.

• First, there is a demand pump, which uses a liquid-fueled compressor that pushes warm air through the ductwork in a continuous loop.
• Second, there is a forced-air system that requires that cool air is pushed through a valve. These systems push cooler air through the ductwork in a constant loop until it reaches the target temperature. Because they require constant pumping of cool air, centralized systems are more expensive to operate.

Regardless of the type of air conditioning system you choose, you need to consider the environment in which you live. Since hot air rises, it can create a moist environment that will cause condensation. Dampness is a problem with most types of air conditioning because it eliminates the air-flow exchange between warm and cold. If your home is prone to dampness, you may want to look into an air conditioning unit that features a water-based cooler rather than a forced-air one.
