摘　　要：近几年,我国有许多大型舒适性中央空调系统投入运行。但制冷规的合理运行管理是一薄弱环节。由于各种原因,许多机组处于低效率工况下运行。本文针对我国宾馆建筑空调的现状,提出根据季节变化,调整制冷机的蒸发温度运行,提高制冷机的cop值,从而降低电力消耗。本文从理论上分析了提高蒸发温度对空调房间热、湿环境的影响,并用现场实测数据验证了该理论。提出了北京地区不同季节的变蒸发温度运行方案。In recent years there are many central air conditioning systems running in our country. It is important to manage them reasonably. Because of various reasons many refrigerators are running in low efficiency.In this paper, we advice to adjust evaporating temperature of refrigerator according to season change. In this way COP of refrigerator will be increased and power decreased. We also analyse how change of evaporating temperature effects on room temperature and humidity.We have taken site-test for running refrigerator at different evaporating temperatures and got some measured data, Finally, we gave out running plan in different months in Beijing.
