Abstract [en]

Within this project the possibility to build a very light and yet effective cooling machine has been investigated. The purpose is primarily to cool electronics in an Unmanned Aerial Vehicle (UAV). Electrically driven cooling machines have been in focus of the project to suit the More Electric Aircraft (MEA) concept. The normal method of cooling aircrafts today is by using a reversed Joule process, also called a reversed gas turbine process. The generally most used cooling machines, both ground-bound and mobile applications, are however all based on the vapor compression cycle, the typical electrical chiller cycle. The latter is more efficient, and thus when including the weight of the fuel needed to power the cooling cycle, it is very likely that the total weight of fuel and the cooling machine itself can be made lighter. Components that could lower the weight of vapor compression machines have been studied, such as new lightweight heat exchangers, motors and compressors. Especially small lightweight compressors would be a key component to further enhance the competitiveness of the Rankine chiller cycles.
