C. The free energy change of dis Sublimation is the phase change from solid to gas without going through a liquid phase. (Solid CO2, called dry ice, is an example of one substance that sublimes.) Use Hess's law to show that the enthalpy of sublima...
In the above formulae, qh is the recovered energy of the total heat exchanger, kw; hs is the specific enthalpy of supply air of the total heat exchanger, kJ/kg; qsh is the outdoor air heating load after heat and humidity exchange, kw; and hn is the specific enthalpy of the indoor ...
The DAE system of this model is given by the system of equations in (6), where M is the mass of the fluid in the vessel, U is the fluid internal energy, T is the fluid temperature, E is the amount of fluid evaporated into the environment, Qe is the energy transferred by the fluid...
