“…Then, the influence of water layer thickness, ice surface heat fluxes, cooling pipe arrangement and temperature, and the top-layer concrete thickness on the ice-making process is discussed. Unless otherwise specified, the basic ice rink parameters are assumed to be as follows: the initial temperature of the water is 10 • C, the fluid temperature in cooling pipes is −17.5 • C, the cooling pipe spacing is 50 mm, the surface heat flux is 290 W/m 2 [12], and the 5 mm water layer is frozen [20,26].…”

“…where n and q c are the boundary normal and ice rink cooling load, respectively. The heat flux on the water layer surface is calculated according to Zhang et al [12]. It is the sum of convection heat transfer flux between air and surface, condensation heat of water vapor in the air, radiation heat transfer between enclosure structures such as ceiling and ice surface, and the lighting load.…”

“…In 2021, Zhou et al [11] established an ice rink discrete thermal resistance circuit model and analyzed the influence of the distance between the cooling pipes on the ice under a steady-state condition. In 2022, Zhang et al [12] performed a parametric analysis of the cooling pipes in an ice rink through a steady heat transfer approach, and the temperature of the working medium in the cooling pipe is suggested.…”

The ice-making process is an important factor that affects the ice quality and the energy consumption of ice rinks. An unsteady heat transfer model is established and validated for the ice-making process. The transient temperature variation and ice thickness growing characteristics during the ice-making process are analyzed. The freezing time of a water layer and the final temperature of the stabilized ice layer are quantified. The effects of ice rink structural parameters on the ice-making process are studied. The results show that the water temperature variations during the process go through three stages. The ice-growing process mainly occurs in the second stage. The ice-making process takes about 305 min–420 min for a water layer of 5 mm thickness. The reduction in the ice-making time and the decrease in the final temperature of the stabilized ice layer can be attained by reducing the water layer thickness, the surface heat flux, the cooling pipe spacing, the fluid temperature in the cooling pipe, or the top concrete thickness. Among them, the influences of the thickness of the water layer, the surface heat flux, and the fluid temperature in the cooling pipe are more significant. As the thickness of the water layer decreases from 7 mm to 3 mm, the total ice-making time decreases by about 37.6%. The ice-making time is reduced by 17.1% with the surface heat flux decreasing from 330 W/m2 to 250 W/m2. The ice-making time is reduced by 21.4% with the cooling pipe temperature decreasing from −15.5 °C to −19.5 °C.
