The TLC Process in the T-S Diagram<\/strong>
The representation of the TLC process in the T-S diagram, the standard representation of heat engine cycles in thermodynamics, shows the eponymous triangle (Tri-Lateral). Alongside is the corresponding p-V diagram.
In the TLC process, the working fluid undergoes the following steps:
– Isochoric pressure increase
– Isobaric heating
– Isentropic expansion evaporation
– Isobaric condensation <\/p>\n\n\n\n

Representation as a Technical Process<\/strong>
The technical interpretation of a T-S diagram is typically familiar only to specialists.
Therefore, a simplified representation of the TLC process as a technical process is provided below.
The numbering refers to the thermodynamic representation in the T-S diagram.<\/p>\n\n\n\n

The TLC Process as a Technical Process<\/strong><\/p>\n\n\n\n

Point 1: Initial state, the working fluid is cold, liquid and unpressurized
Point 1-2: the working fluid is pressurized
Point 2: the working fluid is under pressure
Point 2-3: the pressurized working fluid is heated up without evaporating
Point 3: the pressurized working fluid is hot
Point 3-4: the pressure is reduced, resulting in an expansion evaporation of the liquid working fluid with simultaneous volume increase and decreasing temperature of both liquid working fluid and vapor
Point 4: the working fluid has been partially evaporated by the absorbed thermal energy, is cooled and unpressurized
Point 4-1: the generated working fluid vapor is condensed and the initial state 1 is restored

The Challenge of the TLC Process
<\/strong>The technical challenge of the TLC process is realising the expansion evaporation<\/mark><\/a><\/strong> between points 3 and 4.
The requirements of the TLC process for a heat engine are explained in more detail under Requirements for a TLC Heat Engine<\/mark><\/a><\/strong>.<\/p>\n\n\n\n

Further Development of the TLC Process<\/strong>
Intensive engagement with the scientific findings on the TLC process as well as work on specialized heat engines for the TLC process led to a further development of the TLC process, the Extended-TLC Process<\/mark><\/a><\/strong> (E-TLC Process).<\/p>\n\n\n\n
