医院消毒供应中心压力蒸汽灭菌器节能管理研究

Energy-saving management of steam sterilizers in hospital＇s sterilization and supply center

目的减少消毒供应中心蒸汽灭菌器的能源消耗量并节约成本。方法收集消毒供应中心2016年1-6月压力蒸汽灭菌器的灭菌报表，分析灭菌器各时段的使用情况，包括开机、待机（闲置）、关机情况及各状态的能源消耗量；制定可持续性阶梯式节能管理策略并评价其待机时间（闲置时间）的减少量和能源、成本的节约量。结果灭菌器的使用存在明显的高低峰时段，低峰时段灭菌器待机持续时间长且集中。实施节能管理策略后，低峰期各时段灭菌器待机时间均≤3h（P〈0．001），6个月来待机时间共减少5818h，减少蒸汽消耗量97t、电量2910kW·h，节约科室成本3万余元人民币，约占灭菌器总能源成本的17％。结论阶梯式关闭蒸汽灭菌器的节能管理策略效果显著，能有效降低成本并节能减排。

Objective To reduce the energy consumption and cost of steam sterilizers at sterile supply centers. Methods Routine data of the steam sterilizers from January to June of 2016 were collected from one hospital in Changchun. Usage by timeframe of these sterilizers was analyzed, including their performance when they are powered on, standby （idle） , and powered off and their energy expenditure at such states. Sustainable and stepwise energy saving strategy was developed, with the reduction of standby （idle） period and energy saving amount of energy and cost. Results Usage of sterilizers was found with obvious peak and valley hours, while their standby hours during the latter were long and in a few timeframes. After implementation of the energy saving management strategy, their standby hours at various timeframes averaged ≤3 h （P 〈 0. 001 ）. For six months, we reduced 5 818 hours of standby time, 97 tons of steam, 2 910 kW·h of electricity, saving cost over 30 000 yuan （ 17% ）. Conclusions The energy-saving management strategy could reduce the consumption of energy and cost effectively.
