本文根据L-CNG加气站的特点提出了基于L-CNG加气站冷能利用的蓄冷系统,并根据蓄冰槽管外结冰的特点提出了蓄冰槽管外结冰模型并对模型进行简化。本文结合影响蓄冰槽管外结冰的因素对管外结冰特性进行了分析计算,并研究了不同的载冷剂进口温度、流速、浓度以及蓄冰槽内水的初温等因素对蓄冰槽蓄冷特性的影响。根据计算分析结果,本文提出了适合L-CNG冷能利用系统的蓄冰槽最佳运行工况,为L-CNG冷能利用提供理论基础。
Based on the characteristics of L-CNG refueling station, a cold storage system based on L-CNG refueling station is proposed in this paper. According to the characteristics of ice storage outside the tube, Simplify. In this paper, the factors that affect the outside icing of the ice storage tank are analyzed to calculate the icing characteristics outside the pipe. The effects of different inlet temperatures, flow rates and concentrations of the brine on the initial temperature of the water in the ice storage tank are studied. Effect of ice storage and storage characteristics. According to the results of calculation and analysis, this paper puts forward the optimum operating conditions of the ice storage tank for the L-CNG cold energy utilization system, which provides a theoretical basis for the utilization of L-CNG cold energy.
