  • 层流手术室夏季除湿有什么必要性?
    来源:http://www.moptuan.com 浏览: 发布日期:2019-05-08
    据研究,相对湿度50%时,细菌浮游10min后即死亡;相对湿度更高或更低时,即便经过24h大局部细菌还活着。在常温下,相对湿度60%以上可发霉,80%以上则不管温度的上下都会发霉。所以,标准中手术室请求的相对湿度为30%-60%,当然50%是较为理想。而很多医院夏季空调系统常常会呈现湿度偏高的问题。
    According to research, when the relative humidity is 50%, the bacteria will die after 10 minutes of plankton; when the relative humidity is higher or lower, even after 24 hours, most of the bacteria are still alive. At room temperature, more than 60% relative humidity can be mildewed, and more than 80% will be mildewed regardless of temperature. Therefore, the relative humidity required in the standard operating room is 30% - 60%, of course, 50% is more ideal. The air conditioning system in many hospitals often presents the problem of high humidity in summer.
    要到达除湿的目的是将空气中的水蒸汽凝结出来,层流手术室的除湿是经过干净空调机组的冷水盘管将空气的温度降到送风状态点的露点温度来完成的。送风状态点的露点温度普通在12℃左右,如冷水盘管出风温渡过高,将无法保证送风露点温度,从而室内的湿度也将无法保证。形成湿度超标的缘由主要有:一、空调水系统供水量缺乏;二、空调水系统供水温渡过高,三、空调机组运用年限较长时,冷水盘管的外表污垢较厚时,影响风水换热效果,使冷水盘管换热面积缺乏。
    The purpose of dehumidification is to condense the water vapor in the air. The dehumidification in laminar operating room is accomplished by lowering the air temperature to the dew point temperature of the supply air point through the cold water coil of the clean air conditioning unit. The dew point temperature of the supply air state point is generally about 12 C. If the outlet air temperature of the cold water coil is too high, the dew point temperature of the supply air will not be guaranteed, so the indoor humidity will not be guaranteed. The main reasons for excessive humidity are as follows: 1. lack of water supply in air-conditioning water system; 2. excessive temperature of water supply in air-conditioning water system; 3. when the air-conditioning unit is in service for a long time, the surface fouling of the cold water coil is thicker, which affects the effect of air-water heat transfer and makes the heat exchange area of the cold water coil lack.
    空调水系统供水量缺乏有很多缘由,如水泵选型过小、空调水系统水力不均衡等。水力计算是水泵选型的根据,也是空调水系统能否均衡的根据,可见空调水系统的水力计算十分重要。水泵的流量及扬程,水管的管径应依据水力计算的数据停止选择,水力计算时应思索适宜的水流速。

    There are many reasons for the lack of water supply in air-conditioning water system, such as too small pump selection and unbalanced water supply in air-conditioning water system. Hydraulic calculation is the basis of pump selection and the balance of air-conditioning water system. It can be seen that the hydraulic calculation of air-conditioning water system is very important. The flow rate and head of the pump and the diameter of the water pipe should be selected according to the data of hydraulic calculation, and the appropriate flow velocity should be considered in hydraulic calculation.
    如今很多医院层流手术室夏季冷热源是大楼集中供应的,病房区为温度优先控制,对湿度的请求不是很严厉,只需温度温馨即可,所以对冷水的供水温度请求不用太低,有的医院冷水供水温度高达10℃以上。手术部干净空调系统为湿度优先控制,请求冷水温度为7℃,10℃的冷水温度是满足不了干净空调机组除湿请求。局部医院大楼空调主机在空调机房处提供的冷水温度能到达7℃,但由于手术部净化空调机组的设备层距空调主机远,再加上局部空调水管道的保温层损坏,冷量损耗较大,不能满足干净空调机组除湿请求的冷水温度。
    Nowadays, the cold and heat sources of laminar flow operating rooms in many hospitals are centralized in the building in summer. The ward area is controlled by temperature first. The request for humidity is not very strict. It only needs warm temperature. Therefore, the request for cold water supply temperature is not too low. In some hospitals, the temperature of cold water supply is as high as 10 degrees Celsius. The operation department's clean air conditioning system is the humidity priority control, requesting the cold water temperature to be 7 and 10 is unable to satisfy the dehumidification request of the clean air conditioning unit. The chilled water temperature provided by the main air conditioner in the air conditioning room of local hospital buildings can reach 7 C. However, the chilled water temperature of the clean air conditioning unit can not meet the dehumidification requirement of the clean air conditioning unit because the equipment layer of the air conditioning unit purified by the operating department is far away from the main air conditioning unit and the insulation layer of the local air conditioning water pipeline is damaged.
