Abstract
This article deals with investigation of different factors influence on thermocompressor. These factors include regeneration efficiency, dead volume, working frequency, heat transfer coefficient, thermocompressor diameter and fins application. Calculation shows that most influential factors are regeneration efficiency, dead volume and diameter. It was also found that fins application is not effective for thermocompressor performance enhancement.
Highlights
Thermocompressor (TC) is a device which transform heat directly to a potential energy of pressure
A minimal value of compressor delivery can be seen and it is caused by proximity of diameter value to a diameter corresponding to a minimal heat exchange area
Difference between maximal and minimal values of compressor delivery here is equal to 13.8%
Summary
Thermocompressor (TC) is a device which transform heat directly to a potential energy of pressure. The second one is mechanical device which represents cylinder where piston moves and pushes the gas through the regenerator. This article deals with mechanical thermocompressor with wired regenerator integrated with displacer. Recent studies of thermocompressor are pointed on research of compressor with annular regenerator or thermocompressor operation within different devices. Investigation of the thermocompressor performance with non-isothermal chambers was made in [8]. The results achieved in [8] raise a question of other factors influence on thermocompressor performance. Cold energy utilization efficiency are described in [9, 10]
