Abstract
This paper analyses the heat storage processes in HVAC system and uses the entransy method to calculate the equivalent thermal resistance of energy-storage heat exchangers. Analogous to normal heat exchangers, unmatching coefficient has been introduced to the analysis of energy-storage heat exchanger. It also illustrates the unmatching extent’s influence on thermal resistance for convection in heat absorption process and heat release process under constant temperature boundary condition and constant heat flux boundary condition, respectively. Taking the daytime-heat-absorption and nighttime-heat-release of floor as an example, the unmatching coefficients and proportions of the three parts resistance are analyzed, and the main factors restricting thermal storage performance could be obtained. The results are helpful for the design and optimization of the energy-storage heat exchange system.
