摘要
为解决人体在室外高温下的热危害问题,提出一种流态冰作为蓄冷源的相变式空调衣系统,并对其制冷性能进行分析。计算发现,与液冷式空调衣系统相比,该流态冰系统载冷剂充注量最大可降低58.6%。流态冰的含冰率越高,充注量越低。在外界环境高达45℃时,只需充注2.14 kg的流态冰,即可在2 h内确保人体热舒适性。流态冰管网管径为6 mm时,可充分保障系统冷源的均匀性、结构布置的合理性。
In order to solve the problem of thermal hazard of human body in outdoor high temperature,a phase change air conditioning clothing system with fluidized ice as a cold storage source was proposed,and its refrigeration performance was analyzed.It is found that compared with the liquid-cooled air conditioning clothing system,the fluidized ice system can reduce the charging capacity of refrigerant by 58.6%at most.The higher the ice content is,the lower the filling quantity is.When the external environment is up to 45℃,only 2.14 kg of ice slurry needs to be filled to maintain human thermal comfort within 2 hours.When the diameter of fluidized ice pipe network is 6 mm,the uniformity of cold source and feasibility of structure arrangement of the system can be guaranteed at the same time.
