Ice rinks are a special kind of building with strict indoor requirements and high energy consumption. Indoor thermal environment along with heat and mass transfer in ice rinks with different envelopes are worthy of investigation. On-site measurement was carried out in two recreational ice rinks with different envelope materials. The average air temperature and humidity in the ice field were 8.7 °C, 6.2 g/kg in the concrete structure Rink A while 12.4 °C, 7.9 g/kg in the air-supported membrane structure Rink B. Severe problems of dew condensation, fogging and frosting were observed in Rink A while only frosting occurred in Rink B. The refrigeration load on a typical summer day was 4689 kWh in Rink A and 5611 kWh in Rink B. Long-wave radiation accounts for the most important part in both rinks with a proportion over 44%. By virtue of applying low-emissivity coating on the ceiling, refrigeration load can be reduced by 53.2%. Applicability of air-supported membrane structure in recreational ice rinks is discussed. The current research is beneficial for the design and operation of ice rinks.

不同围护结构冰场热环境及传热特性研究

溜冰场是一种特殊的建筑,室内要求严格,能耗高。具有不同围护结构的溜冰场的室内热环境以及传热传质是值得研究的。在两个具有不同外壳材料的休闲溜冰场进行了现场测量。冰场平均气温和湿度为 8.7 ℃,混凝土结构 Rink A 为 6.2 g/kg,而空气支撑膜结构 Rink B 为 12.4 °C,7.9 g/kg。结露问题严重,冰场 A 出现起雾和结霜,冰场 B 仅出现结霜。典型夏季一天的制冷负荷为 A 冰场 4689 千瓦时和 B 冰场 5611 千瓦时。长波辐射占两个冰场的最重要部分占比超过 44%。天花板采用低辐射涂层,制冷负荷可降低53.2%。讨论了气支撑膜结构在休闲溜冰场中的适用性。目前的研究有利于溜冰场的设计和运营。
