Chillers are devices that eliminate heat from a fluid through a vapor-compression or absorption refrigerant cycle, and discard that heat elsewhere. Cool fluid generated by the chiller is dispersed within a heat exchanger to cool and dehumidify fluid in various commercial, industrial, and medical facilities. In addition, ice cold water is utilized for different industrial applications, which include food processing, patient cooling, equipment cooling, and others.

Countries such as Germany, China, and the US are at the forefront of regulating commercial deployment of L4 vehicles by 2022, including both autonomous cars and shuttles for passengers.
