摘要:To maintain ice quality, the ice rink requires multiple resurfacings, involving complex heat and mass transfer properties. A validated transient model for these processes has been developed, examining transient updated surface temperature (tus), cooling pipe heat flow (Qcps), and updated surface heat flow (Qus). Thermal response delay and heat accumulation are observed and quantified during the process. The effects of required ice surface temperature (tris) and resurfacing interval (Delta tau) on these variables are analyzed. The results indicate that the instabilities of Qcps and Qus result in heat accumulation, which led to a significant increase in tus,Delta tau and a prolongation of the steady time of the final resurfacing. tus,Delta tau increases linearly by about 0.10 degrees Cas the increase of resurfacing times. The steady time of the final resurfacing increases by 41.1-81.4 % versus single resurfacing. The Qcps,max increase rate versus the steady-state ice surface heat flow is between 14.4 % and 38.5 %. When the required surface temperature increases from-9.0 degrees C to-3.0 degrees C, the Qcps,max increase rate versus single resurfacing varied from 1.3 % to 7.9 %, the Qcps,max appearing moment after the resurfacing initiation decreases from the 19.5th minute to the 18.3th minute. When the resurfacing interval inecreases from 30 min to 150 min, the Qcps,max increase rate versus single resurfacing varied from 18.3 % to 1.1 %, the Qcps,max appearing moment after the resurfacing initiation increases from the 15.2th minute to the 20.7th minute. When the resurfacing interval reaches 120 min, the increase in tus and heat accumulation are significantly weakened, which helps to avoid the risk of excessive ice temperature and refrigeration system overload.
