摘　　要：中央空调由粗放型 ,向质量型、经济型转变 ,要靠科技创新。根据制冷四大循环原理与相互间的关联 ,进行综合研究分析 ,确定降低冷却水4℃ ,可使制冷机耗电指标由0.186kW,下降到0.121kW以下。经调整后我院1250万千卡中央空调制冷系统 ,每年夏季节约运行费用200万元左右 ,且对制冷机安全运行 ,延长制冷机使用寿命 ,特别是对全封闭和半封闭制冷机的电机有着重要安全保护作用。同时还减少了冷却水中钙、镁离子的聚集成垢 。The change from extensive model to quality model and economical model of Central Air Conditioning relies on technological innovation.On the base of refrigeration cycle theory,a comprehensive study is made.Decreasing4℃of cooling water's temperature can descend proportion of consume and electric power from0.186to0.121or lower.The Central Air Conditioning system of12.5million Kcal in our hospital can save about2million RMB dollars every summer.This improvement can make refrigeration machine run sagely and prolong life,especially can protect the electrometer of full-close and half-close compressor.Simultaneously,this can reduce the furring chance of calcium ion,magnesium ion and the breeding probability of legionella in cooling water.
