不同空调系统对解剖实验室气态甲醛污染状况改善的实验观察

目的探讨不同设计的空调系统降低人体解剖实验室内甲醛浓度的效果。方法在同一个人体解剖实验室内设计安装两套不同的空调系统,即单元空调器(甲型)及工艺性空调系统(乙型),通过计算室内冷负荷,确定空调系统的通风、排气强度,分别在不开空调、开甲型、开乙型时,在3个固定采样点,分别采集室内空气,比较3种不同状态下室内空气中甲醛浓度的差异。结果甲、乙两型及甲、乙两型分别与不开空调系统相比,室内空气甲醛浓度测定结果之间差异有显著意义。结论乙型空调系统效果明显优于甲型。

Experimental Observation of Improvement on the Formaldehyde Pollution in Human Anatomy Laboratories Based on Different Air Conditionings

Objective Studying the effect of different-designed air-conditioning on reducing the density offormaldehyde in the human anatomy laboratory.MethodsInstalling two types of air-conditioning,unit air-conditioner(type A) and technological air-conditioner(type B)in the same laboratory,calculate the indoor cooling load and determine the strength of ventilation and exhalation of the technological air-conditioner.Collecting three different air samples on type A,type B and off them,then compare the density of formaldehyde in these different conditions.ResultsThe density of formaldehyde in the human anatomy laboratory differs respectively.ConclusionType B is superior to Type A in reducing the density of formaldehyde.
