目的预防和控制某超市餐饮区集中空调通风系统可能出现的健康危害因素。方法对施工设计进行卫生审查,现场调查周围环境状况,开展危害因素监测,对获得资料数据进行分析,并依据卫生标准做出评价。结果某超市餐饮区集中空调通风系统设计温度参数依据标准不正确;空调制冷设计不能满足夏季冷负荷要求;送风前缺少净化消毒装置,不符合卫生要求。环境危害因素监测指标均符合标准要求,适合建设项目选址定点建设。结论建议全面考虑超市餐饮区服务特点,优化集中空调通风系统设计,保证公共场所环境卫生安全。
Objective To prevent and control possible health hazard factors in the centralized air conditioning and ventilation system of a supermarket catering area. Methods To carry out health examination on construction design, investigate the surrounding environment on site, carry out the monitoring of hazard factors, analyze the obtained data and make evaluation according to the health standards. Results The temperature parameters of the centralized air-conditioning and ventilation system in a supermarket’s dining area were not based on the correct standards. The air-conditioning and refrigeration design could not meet the requirements of summer cooling load. The lack of purification and disinfection devices before air supply did not meet the hygiene requirements. Monitoring indicators of environmental hazards are in line with standard requirements for construction site selection site construction. Conclusion It is suggested to fully consider the service characteristics of the supermarket catering area, optimize the design of centralized air conditioning and ventilation system, and ensure the environmental sanitation safety in public places.
