The recently discovered Topological Theory of Quantum Gravity (TTQG) is basically a Theory of Space Quantization (TSQ) and in this article first of all it has been substantiated that though the laws of thermodynamics, the well-known thermodynamic principles, the operations of heat engines are very much intuitive but they, in their conventional representations, miserably lack the harmony to the quantized ‘space -time’ of the universe. The well-known thermodynamic parameters, e.g., pressure (P), volume (V), heat content (H), internal energy (U), entropy (S), Gibbs free energy (G) ,….etc. and the related physical variables like ‘time’ ( t ) and ‘mass’ (m) do exist in the form of ‘quantum’ or ‘packets’( referred as Gravitons in TTQG) and those are continuously being exchanged between the so called ‘thermodynamic systems’ and the ‘space-time’. It has been shown in this article that a ‘thermodynamic system’ and the above said ‘space quantums’ are very much complimentary and ‘part and parcel’ to each other and a quantum level ‘space-time’ rich understanding has been made through the TSQ of the true logic behind the standing of the thermodynamic laws and the operations of the heat engines.
