Properties of India

Air conditioning engineers broadly divide air conditioning applications into comfort and process.

Comfort applications aim to provide a building indoor environment that remains relatively constant in a range preferred by humans despite changes in external weather conditions or in internal heat loads.

Air conditioning makes deep plan buildings feasible, for otherwise they'd have to be be built narrower or with light wells so that inner spaces receive sufficient outdoor air via natural ventilation. Air conditioning also allows buildings to be taller since wind speed increases significantly with altitude making natural ventilation impractical for very tall buildings. Comfort applications for various building types are quite different and may be categorized as

• Low-Rise Residential buildings, including single family houses, duplexes, and small apartment buildings
• High-Rise Residential buildings, such as tall dormitories and apartment blocks
• Commercial buildings, which are built for commerce, including offices, malls, shopping centers, restaurants, etc.
• Institutional buildings, which includes hospitals, governmental, academic, and so on.
• Industrial spaces where thermal comfort of workers is desired.

In addition to buildings, air conditioning can be used for many types of transportation - motor-cars and other land vehicles, trains, ships, aircraft, and spacecraft.
