Abstract
As part of the research in the field of pumping vacuum chambers in the Environmental Electron Microscope, research on supersonic flow through apertures is being carried out at the Department of Electrical and Electronic Technology of the Brno University of Technology in cooperation with the Institute of Scientific Instruments of the CAS. This research, which deals with gas compression and expansion, utilizes this experience in the paper that deals with the issue of gas heating during compression when filling a storage tank as an energy storage device. This heating of the gas is a loss relative to the stored energy and there is an interest in limiting this heating or using this heat in other ways. This paper deals with limiting the heating of compressed air when filling a storage tank as energy storage.
