Abstract—Mechanical thermocompressor is suited for gas compression with constant volume by means of heat addition. Its classic modelling theories usually do not take into account non-isothermal conditions of its chambers. This article deals with thermocompressor modelling with non-isothermal hot and cold chambers. The results of the modelling show significant loss (16.45%) of compressor delivery due to non-isothermal conditions of its chambers. Maximal mass mean temperature deviations for cold and hot chambers are equal to 14.98% and -8.5% correspondingly.
