我们通过建立的实验系统测试了椭形蓄冷单体在充冷中换热的各种参数,得出冷媒与蓄冷剂之间的传热热阻R(ε,m0)、蓄冷体内的结冰率ε和冷媒流率m0,从而能够很简便地使用R(ε,m0)表达式揭示蓄冷器充放冷能力本质因素,得出任一工况下的蓄冷器运行情况,优化设计整个系统,包括蓄冷器本身在充放冷过程中运行参数的确定。由此根据上述结构设计了180000kcal蓄冷量的模块化椭形单体冰蓄冷器,并在华北油田试验成功。
Through the established experimental system, we have tested various parameters of the heat exchange between the refrigerant and the regenerator in the process of cold charging, and obtained the heat transfer resistance R (ε, m0) between the refrigerant and the regenerator, the icing rate in the regenerator ε and the refrigerant flow rate m0, so that it is easy to use the expression of R (ε, m0) to reveal the essential factors of the charge-discharge capacity of the regenerator, obtain the operating conditions of the regenerator under any operating conditions and optimize the design of the entire system, including cold storage The device itself in the charge and discharge process to determine the operating parameters. Based on the above structure, a modular elliptical monosolectic regenerator with capacity of 180,000kcal was designed and tested successfully in Huabei Oilfield.
