Refrigeration Engineering plays important role in manufacturing and production processes including food preservation technologies (processing, freezing, storage and transportation) to provide sufficient quantities to feed growing population.
Air Conditioning Engineering has been applied to provide and maintain controlled environment in building such as office, house, and factories, also for other large structures such as tunnels. In the aviation fields its application includes human-occupied spaces, aircraft''s equipment operation, satellites and space station. It also presents in manufacturing and fabrication technology and pharmaceutical processes to provide controlled enviromental conditions.
