目的通过对张家口市崇礼区滑雪场所室内空气卫生质量进行评价,探索滑雪场所集中空调卫生管理对策。方法采用影响环境评价理论构建集中空调环境影响评价体系,对张家口市崇礼区滑雪场所集中空调环境进行评价。结果在张家口市崇礼区滑雪场所集中空调中影响比较大的环境影响因子主要有:军团菌、冷却塔污染、细菌、溶血性链球菌等,生物因素影响因子中影响最大的来自军团菌;化学因素影响因子中影响最大的是新风口气体排放;物理因素影响因子中影响最大的是冷却塔污染。6.50%的专家认为滑雪场所集中空调环境综合效益为很满意;19.16%的的专家认为滑雪场所集中空调环境综合效益为满意;44.33%的的专家认为滑雪场所集中空调环境综合效益为较满意;23.38%的专家认为滑雪场所集中空调环境综合效益为一般;而只有6.64%的专家认为滑雪场所集中空调环境综合效益为不满意。结论张家口市崇礼区滑雪场所集中空调系统可能存在生物污染、化学污染和物理污染,集中空调通风管理中需要重点加以控制。
Objective To evaluate the indoor air quality of skiing places in Chongli District, Zhangjiakou City, and to explore the health management countermeasures of the centralized air conditioners in ski resorts. Methods Based on the theory of environmental impact assessment, the environmental impact assessment system of centralized air conditioners was constructed to evaluate the central air conditioning environment in ski resorts in Chongli District, Zhangjiakou City. Results In Zhangjiakou City Chongli District, the main influencing factors of air conditioners in central air conditioners were: Legionella bacteria, cooling tower pollution, bacteria, hemolytic streptococcus and so on. The most influential factor of biological factors was Legionella; Factors affecting the most influential factor is the new outlet gas emissions; physical factors affecting the most influential factor is the cooling tower pollution. 6.50% of experts believe that the overall efficiency of the skiing environment is very satisfied with the overall air-conditioning environment; 19.16% of the experts believe that the overall efficiency of the ski-focused air-conditioning environment is satisfied; 44.33% experts believe that the overall efficiency of the ski air- % Of experts believe that the overall efficiency of air-conditioned environment for skiing is general; and only 6.64% of experts believe that the overall efficiency of air-conditioned environment for skiing is not satisfied. Conclusion There may be biological pollution, chemical pollution and physical pollution in the centralized air-conditioning system of ski resorts in Chongli District, Zhangjiakou City. The centralized air-conditioning and ventilation management needs to be emphasized and controlled.
