采用蒸发冷却的辐射供冷空调系统室内热环境模拟验证
Simulation Study on Indoor Thermal Environment of Radiant Cooling System Based on Evaporative Cooling
摘要
Abstract
In northwest China, because of the hot and arid summer climate, the cooled water of radiant cooling and cooled fresh air can be provided by evaporative cooling method with a high COP. That constitutes a hybrid radiant cooling air conditioning system based on evaporative cooling. The schematic diagram of the hybrid system was introduced. The indoor thermal environment of radiant floor and displacement ventilation system as well as chilled ceiling and displacement ventilation system were simulated by software Airpak. The simulation results indicated that the vertical temperature difference of the former system was higher than that of the later system. The corresponding temperature differences between 0. Lm and 1.1m heights of both systems were lower than 3℃, the recommended comfort value of ISO7730 comfort standard. The simulated indoor air temperatures meet the designed criteria. The numerical simulation results coincided well with experimental data. Indoor thermal environment of proposed hybrid system can be further studied by this method.关键词
