THERMO-ENGINEERING DEVICE FOR EXECUTING THERMODYNAMIC PROCESS CONSISTING OF TWO KIND OF MUTUALLY CONTRADICTORY PHASE TRANSITION OF WORKING MEDIUM

摘要

Thermo-dynamical processes which comprise mutually opposite phase transitions of a work medium are carried out in a heat-engineering apparatus composed of casings (100-102-100). The casings consist of spacers 102 sandwiched by a pair of confining plates 100. A casing encompasses one or a plurality of phase transition compartments which unit pairwise to work chambers in which mutually opposite phase transitions occur. If the phase transition compartments are located in different casings, such casings are abutted against one another flatwise along common confining plates. If complete work chambers are disposed in single casings, there are partitions (112) which subdivide a casing in a plurality of phase transition compartments. In both cases the associated phase transition compartments open directly into one another through an orifice (106) in the confining plate and the partition, respectively. Combinations of various confining plates and spacers permit to build heat-engineering apparatus such as multi-flash and multi-effect evaporators, sorption-type refrigerators and the like by employing and association casings of different types which comprise all auxiliary equipments such as condensing vessels, demisters, pressure reducing means, heat exchangers and the like. Required outputs will be obtained by selecting the number of casings accordingly.
