基于伪装和节能需求的防护工程热湿环境分区分时调控

Protection engineering is used in national defense combat readiness. Its internal thermal and humid environment is an important factor to guarantee the officers and equipment system play a role and has the dual requirements of safety and energy efficiency. The current protection engineering air conditioning systems can not meet the requirement of the temperature and humidity of different parts of area and can not meet the requirement of the various stages of the air conditioning when considering the peacetime and wartime at the same time. This topic puts forward a kind of protective engineering thermal and humid environment control technology which called phase change reservoir/buried pipe water loop heat pump air conditioning system. The new technology can not only meet the engineering disguise requirements, but solve engineering problems of the waste heat emissions within the time difference and the space distribution inhomogeneity. Methods of the combination of theoretical analysis, numerical simulation and experimental study will be used. Based on the protective engineering internal thermal comfort PMV correction and study of time-division thermal comfort parameters in field investigation, the integration and heat transfer characteristics of composite cold source within the buried pipe heat release and phase change storage reservoir will be discussed and the optimized allocation and operation strategy of the phase change reservoir /buried tube heat and cold source water loop heat pump air conditioning systems will be studied. The results can provide theoretical basis and technical support for solving the protecting technical problems of protection engineering internal thermal and humid environment and the usage of phase change reservoir/buried pipe water loop heat pump air conditioning system.
