Describes the mathematical models related to the laws of conservation to predict laboratory temperature and pressure. Steady-state results are presented and discussed to demonstrate the relationship between the control parameters and the heat load. Finally, the simulated results are included to predict the transient effect of heat load on the dynamics of the laboratory environment.
