Air conditioning design refers to the process of designing a system that provides a comfortable and healthy indoor environment by controlling temperature, humidity, and air quality through the use of air conditioning equipment. The design process begins with an assessment of the heating and cooling requirements of the space to be conditioned. This involves calculating the cooling load, which is the amount of heat that must be removed from the space to maintain a comfortable temperature. The designer then selects the appropriate type and capacity of air conditioning equipment, such as central air conditioning systems, split air conditioning systems, or ductless mini-split systems.

The design process also involves considerations such as energy efficiency, air quality, and noise control. Air conditioning designers must adhere to local building codes and regulations, which set minimum standards for the design, installation, and operation of air conditioning systems.

"Air conditioning design can be applied to a wide range of buildings and spaces, including residential homes, commercial buildings, hospitals, and industrial facilities. The design process may involve collaboration between mechanical engineers, architects, contractors, and other stakeholders to ensure that the air conditioning system meets the needs of the building and its occupants."
