With the increasing market demand for high-quality aquatic products, the application of industrialized aquaculture facilities may get more attention. In order to improve the poor performance of thermal insulation, the accuracy of the numerical model was verified in this study through actual measured data. The model verification results shown that the average relative errors of the measured and calculated values of indoor air temperature, water temperature and roof inner surface temperature in the industrialized aquaculture workshop is within 2.5%, it suggested that the numerical calculation results are accurate. Furthermore, the thermal environment and thermal insulation performance of industrialized aquaculture facilities in winter were conducted based on the numerical calculations. After optimized the thermophysical parameters of the workshop enclosure structure, we found that the water body temperature could reach 21°C (which was close to the breeding temperature of grouper (Epinephelinae). Therefore, the numerical calculation method was further used to analyze the energy consumption of aquaculture water in January of a typical year in this area by heating to three constant temperatures (22, 25, and 28°C). When the aquaculture water was heated to the three constant temperature states, it needed to consume 8.56×105, 1.02×106 and 1.22×106 MJ of energy respectively, which were equal to the amount of energy released by the complete combustion of 29.3, 35.1 and 41.8 t standard coal. Moreover, it is concluded that the artificial temperature increase in winter maintains the temperature in the range of 22~25°C to provide the highest heating efficiency. This conclusion can provide theoretical basis and application reference for industrialized aquaculture in winter.

随着市场对高品质水产品的需求持续攀升，工厂化水产养殖（industrialized aquaculture）设施的应用正获得愈发广泛的关注。为改善保温性能欠佳的现状，本研究通过实测数据对数值模型（numerical model）的准确性开展验证。模型验证结果表明，工厂化水产养殖车间内的室内空气温度、水温及屋顶内表面温度的实测值与计算值的平均相对误差均控制在2.5%以内，证明数值计算结果具备较高准确性。随后，本研究基于数值计算结果，对工厂化水产养殖设施冬季的热环境与保温性能进行了分析。在对车间围护结构的热物理参数完成优化后，研究发现水体温度可达到21℃，该数值接近石斑鱼（Epinephelinae）的养殖适宜温度。进一步地，本研究采用数值计算方法，分析了该区域典型年份1月养殖水体分别加热至22℃、25℃、28℃三个恒温状态下的能耗情况。当养殖水体处于这三个恒温状态时，所需能耗分别为8.56×10⁵、1.02×10⁶及1.22×10⁶ MJ，相当于完全燃烧29.3吨、35.1吨及41.8吨标准煤（standard coal）所释放的能量。此外，研究得出结论：冬季人工升温将水温维持在22~25℃区间内，可实现最高的供暖效率。该结论可为冬季工厂化水产养殖提供理论依据与应用参考。
