This paper tackles the issue of frost formation in air-to-air heat recovery devices dedicated to single room ventilation by means of both numerical simulations and experimental approaches. In such heat exchangers, it is commonly known that the formation of a frost layer on the surface generates an additional thermal resistance and a flow section reduction, which leads to an overall degradation of the overall unit performance. This paper proposes a three-zone model, considering a dry, a wet and a frost zone, by determining the location of moving boundaries. Each zone is handled independently and the relative proportion of each zone is determined by means of the exchanger wall temperature. Besides this frost model, a defrost model is also envisaged. Once validated with experimental data collected on a U-flow-type heat exchanger, the developed model is used to implement different strategies to reduce or prevent frost formation in the exchanger. Based on three different criteria, these strategies are compared with each other to evaluate their benefits and drawbacks. The criteria give information on the energy efficiency of the ventilation, on the air renewal quality and on the pressure balance between the inside and the outside of the building.

“…Under strong convection, the new desublimated water vapor mainly contributes to the increase of the frost thickness, rather than increases the density of the frost layer. However, the desublimated water vapor increases both the thickness and the density of the frost layer under low airflow velocity [10]. As the frosting progresses, the frost surface temperature gradually increases, and when the water vapor content in the humid air is equal to the saturated water vapor content at the frost surface temperature, the water vapor in the humid air will stop changing into frost.…”

“…The first type is the one-dimensional model, which uses empirical correlations obtained from experiments to calculate the heat transfer coefficient and mass transfer coefficient on the frost surface [7][8][9]. Nevertheless, the one-dimensional models cannot reflect the characteristics of complex surface shape, and are usually applied to the research of frosting on cold plates [10]. Moreover, this type of models does not solve the coupled flow and heat transfer problems in air and frost, so it cannot be used to predict the frost formation under changing flows with frosting.…”

A newly developed frosting simulation method, p-VOF method, is applied to simulate the dynamic frost formation on the NACA0012 airfoil under strong convection. The p-VOF method is a pseudo VOF method of the multiphase flow simulation with phase change. By solving a simplified mass conservation equation explicitly instead of the original volume fraction equations in CFD software, the efficiency and robustness of calculation are greatly improved. This progress makes it possible to predict a long-time frost formation. The p-VOF method was successfully applied to the simulation of dynamic frosting on the two-dimensional NACA0012 airfoil under strong convection conditions with constant frost physical properties. The simulation result shows that the average thickness of the frost layer increases, and the frost bulges and flow separation appear earlier, when the airfoil surface temperature decreases or the air humidity increases. The frost bulges and flow separation appear earlier, when the air velocity is faster, the growth rate of the frost layer at the early stage is greater, but the final frost layer is thinner.

A newly developed frosting simulation method, pseudo-VOF (p-VOF) method, has applied to simulate the dynamic frost formation on the NACA0012 airfoil under strong convection.

By solving a simplified mass conservation equation explicitly instead of the original volume fraction equations in CFD software, the efficiency and robustness of calculation are greatly improved.
