【摘要】 随着家用空调的日益普及,空调耗电量急剧增加。我国开发与推广小型家用蓄冷空调器,其转移尖峰用电负荷的潜力将比在中央空调系统上发展蓄冷空调大得多。小型家用蓄冷空调系统采用外融冰蓄冷,可以明显地节省运行费用;系统采用直接蒸发方式进行蓄冷,可避免冷热转换的中间环节,减少了能耗;相变温度为5～8℃的相变材料利用潜热进行蓄冷,可以改善制冷系统的运行特性。因此研制冰蓄冷与相变材料蓄冷混合的蓄冷空调系统是有意义的。更多还原

【Abstract】 With the popular of the residential air-conditioner,power consumption increases rapidly.The potential of transferring peak load to research and develop small residential cold-storage conditioners(SRCSC)is bigger than ice-storage central air-conditioning systems.The SRCSC with external melt ice-on-coil can save operation cost obviously.System with direct evaporation can leave out middle heat exchange and decrease energy consumption.In addition,phase change material(PCM) with 5～8℃ can carry on cold storage by latent heat,ameliorating running performance.So it is significant to study the combination system of ice-storage system and phase change material.更多还原
