摘要
建立了准稳态量热计,通过测量纯水和正庚烷的比热容,对量热器进行了检验。比热容的测量结果与文献标准值比较,最大偏差不超过1.0％,表明量热器具有较高的精度和稳定性。在此基础上测量了含氧燃料添加剂碳酸二甲酯及可作为蓄热介质石腊的比热容,为混合燃料的设计和空调余热利用提供基础数据。
A quasi-steady-state calorimeter was developed. The calorimeter was verified by means of measuring heat capacities of pure water and n-heptane. The maximum deviation is in within 1.0 percent by comparing obtained values of heat capacities with the literature values. The heat capacities of dimethyl carbonate (DMC) which is used as fuel additive and paraffin wax which is used for thermal energy storage from air-condition condenser were measured.
