This dataset primarily includes simulation and experimental data derived from two core research directions: theoretical studies on ice surface formation for speed skating rinks, and key technical research on the construction of indoor multi-functional super-large ice surface ice pools. A theoretical analysis model was established to describe the ice surface formation process under rink scenarios and its relationship with the indoor environment. It details the internal temperature distribution of the ice layer and the temporal characteristics of the ice surface formation process during stages such as ice watering, freezing, and ice resurfacing, and clarifies the variation laws of heat and mass transfer on the ice surface under the influence of factors including external environmental parameters and internal ice layer structure across multiple operating conditions.

The dataset also contains experimental data from key technical research and demonstration applications of multi-functional super-large ice surface carbon dioxide ice-making systems. Adopting the natural environmentally friendly refrigerant CO₂, a subcritical and transcritical multi-operating-condition parallel compression CO₂ direct evaporation ice-making centralized refrigeration system applied to the ice-making system of the National Speed Skating Oval was constructed. In-depth research was conducted on the ejector system, heat recovery system, and parallel compression system, and key technical challenges such as pressure oil return in subcritical and transcritical multi-operating-condition parallel carbon dioxide centralized refrigeration and two-stage temperature-adjustable energy-storage heat recovery were overcome. The CO₂ refrigeration system efficiently meets multiple functions including ice-making, dehumidification, and domestic hot water under outdoor wide-temperature-range multi-operating-condition conditions.

Additionally, the dataset covers simulation and experimental data from key technical research and demonstration applications of precise indoor environment control. The computational fluid dynamics (CFD) method was used to model the air distribution in the tall space of the speed skating venue, and experimental verification was carried out through on-site testing. The distribution laws of the indoor environmental temperature field, humidity field, and velocity field under the influence of the super-large ice surface in the tall space of the speed skating venue, as well as the action laws of influencing factors, were studied, providing scientific support for precise indoor environment control.

Finally, the dataset includes experimental data from key technical research and demonstration applications of automated monitoring for ice surface and environment. The coupling effect between ice surface temperature and the environment was studied, and the dynamic regulation characteristics of ice surface temperature and indoor environment under various disturbance and control factors were discussed. An accurate control strategy and automated monitoring technology method based on adaptive control were established. The precise monitoring technology for the super-large ice surface and indoor environment in the venue is an important way to ensure that the thermal and humid environment of the venue meets the relevant standards.
