In refrigeration we use the Gas Laws to explain the behavour of gases, but if we measure very carefully we find that most gases do not exactly follow the rules. Engineers have developed more advanced methods, with the help of computer software modelling, to get more exact answers.
Engineers invent, design and make useful things. Engineering covers a very wide field, from the microscopic computer chips to enormous construction projects, everything man-made that moves, and of course refrigeration, air conditioning and heat pumps.
The career opportunities for anyone studying engineering are vast and growing. See our careers section for more information about the kinds of work that refrigeration and air conditioning engineers get inovlved with.
In these pages in the Cooling Science section of this website we are going to take an indepth look at the science and engineering of cooling.
