One of the inventions that have substantially improved people's quality of life is air conditioning. There are many different types of air conditioning systems available in the market.
Depending on the area that has to be cooled, there are multiple types of air conditioning systems in varying sizes and with varied technologies and capacities, more than a century after Carrier's initial patent. Residential systems, of course, differ from commercial and industrial systems due to the differences in space and user needs.
Types of Air Conditioning System:
Mini-splits are a great alternative to central air because they don't require ductwork or vents. The "mini" in their name refers to the low-profile indoor evaporator unit(s) that are mounted on walls and only require small holes for the various lines: refrigerant, condensation drain, and electricity.
The "split" element refers to the outside condenser unit, which is distinct from the indoor unit (or "split") (s). Mini-split systems are more costly and have a lesser capacity due to their smaller size, but they are more energy-efficient than forced air systems and hence cost less to operate.
Chilled water system
Water is a refrigerant as well as a thermal fluid. Hot water or steam radiates heat in indoor rooms in a typical boiler system, which can be found in both houses and industrial establishments.
A chilled water system, on the other hand, absorbs heat by pushing water that has been cooled to roughly 45°F (7°C) via piping beneath floors, in walls, and on ceilings. This technology can be used to cool a single building or, in the case of a chiller plant, a group of buildings, or even an entire high-density area (district cooling).
Geothermal heating and geocooling
The air temperature varies greatly, yet it is always a pleasant 55°F (13°C), barely 10 feet (3m) below the ground. Although geothermal heating and cooling are costly upfront, they are gaining popularity as consumers and companies look for methods to save money on energy. These systems essentially consist of a loop of subterranean pipes through which water circulates. When it's cold outside, air-temperature water is delivered underground to warm up; when it returns aboveground, a heat pump raises the temperature to the necessary level and feeds it through the building's pipes. The method works on the same concept in hot temperatures but in reverse.
