Originální abstrakt
The adiabatic sorption is very interesting phenomenon that occurs when vapor of refrigerant is in contact with unsaturated liquid absorbent refrigerant mixture and exchange of heat is forbid between the system and an environment. This contribution introduces new auxiliary lines that enable correct position determination of the adiabatic sorption process in the pTx diagram of ammonia water system. The presented auxiliary lines were obtained from common functions for fast calculation of water ammonia system properties. Absorption cycles designers often utilize p t x diagrams of working mixtures for first suggestion of new absorption cycles. The p t x diagrams enable fast correct determination of saturate states of liquid (and gaseous) mixtures of refrigerants and absorbents. The working mixture isnt only at saturated state during a real working cycle. If we know pressure and temperature of an unsaturated mixture, exact position determination is possible in the p t x diagrams too.
Český abstrakt
Adiabatická sorpce je jev, který nastane, když páry chladiva jsou v kontaktu s nenasycenou absorpční směsí při zamezení výměny tepla s okolím. Tento příspěvek publikuje nové pomocné čáry, které umožňují rychlé určení adiabatické absorpce v PTX diagramu roztoku voda – čpavek. Prezentované pomocné čáry byly sestrojeny pro rychlý výpočet parametrů adiabatické absorpce.
