Health management and critical point control of central air conditioning in skiing park in Chongli District of Zhangjiakou City of Hebei Province

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 in Chongli District, exploring the health management measures of central air conditioning in skiing park. Methods Building central air conditioning system of environmental impact assessment by which influence the environmental assessment theory, to evaluate the environmental of air conditioning in Chongli skiing park. Results In central air conditioning of Chongli skiing areas, which influence more are- legioaella, cooling tower pollution, bacteria, hemolytic streptococcus and so on. Which makes a big influence in biological factors is legionella; in chemical factors, the greatest impact is the new degassing exhaust; and in physical factors, the greatest impact is the cooling tower pollution. 6. 50% experts very satisfied the comprehensive benefits of air conditioning in skiing park; 19. 16% experts satisfied the comprehensive benefits; 44. 33% experts relatively satisfied; 23. 38% experts are average satisfied; and only 6. 64% experts are unsatisfied the benefits. Conclusion There may exist biological pollution, chemical pollution and physical pollution in central air conditioning system in skiing resorts of Chongli Zhangjiakou, and central air conditioning ventilation management needs to focus on control.
