  • 手术室装修中空调系统三种处理方式
    来源:http://www.sdyhrs.com 浏览: 发布日期:2020-06-29
    手术部主要功能房间为手术室,目前国内手术部设计中Ⅰ级手术室和Ⅲ级手术室(手术室区为万级)数量设置多。今天净之源说说手术室装修空调系统中常用的三种空气处理方式。
    The main functional room of the operating department is the operating room. At present, there are many level I operating rooms and level III operating rooms (the operating room area is 10000 level) in the domestic design of the operating department. Today, jingzhiyuan talks about three kinds of air treatment methods commonly used in the air conditioning system of operating room purification and decoration.
    (1)新风集中处理至室内等焓值点,循环机组采用一次回风方式。手术室净化装修中,新风设置独立新风机组,新风集中处理后送至各循环机组与回风混合,循环机组将混合后空气处理至送风状态点(O点)送风。
    (1) The fresh air is centralized to the indoor constant enthalpy point, and the circulating unit adopts the primary return air mode. In the purification and decoration of the operating room, the fresh air is provided with an independent fresh air unit. After centralized treatment, the fresh air is sent to each circulating unit to mix with the return air. The circulating unit processes the mixed air to the air supply state point (o point) for air supply.
    (2)新风集中处理至室内等焓值点,手术室净化装修循环机组采用定二次回风方式。新风集中处理后送至各循环机组,新风与一次回风混合,再经过表冷器处理后与二次回风混合,再将混合后空气加热至送风状态点送风。
    (2) The fresh air is concentrated to the indoor enthalpy point, and the fixed secondary return air mode is adopted for the operating room purification and decoration circulating unit. The fresh air is sent to each circulating unit after centralized treatment. The fresh air is mixed with the primary return air, and then mixed with the secondary return air after being treated by the surface cooler, and then the mixed air is heated to the air supply state point for air supply.
    (3)新风集中处理至承担室内湿负荷状态点(深度除湿),循环机组采用一次回风方式。新风承担室内湿负荷,将新风直接处理至机器露点,然后新风与回风混合,再由循环机组处理至室内送风状态点。
    (3) The fresh air shall be treated to the indoor wet load point (deep dehumidification), and the circulating unit shall adopt the primary return air mode. The fresh air bears the indoor wet load, and the fresh air is directly treated to the dew point of the machine, then the fresh air is mixed with the return air, and then treated by the circulating unit to the indoor air supply state point.
    此种处理控制方式通常也称为温湿分离控制,即新风主要负责湿度控制,循环机组主要负责房间内温度控制。
    This kind of treatment and control method is usually also called temperature and humidity separation control, that is, fresh air is mainly responsible for humidity control, and circulating unit is mainly responsible for temperature control in the room.
    通常情况下,一个手术部中,Ⅰ级手术室间数所占比例约百分之20,Ⅲ级手术室所占比例约为百分之80。Ⅱ级和Ⅳ级手术室实际使用中较少设置。所以下面主要比较Ⅰ级和Ⅲ级二个类型的手术室在三种不同空气处理方式下的能耗情况。

    手术室装修
    Generally, in an operating department, the proportion of grade I operating rooms is about 20%, and that of grade III operating rooms is about 80%. Grade II and grade IV operating rooms are rarely set up in practical use. Therefore, the following mainly compares the energy consumption of two types of operating rooms of grade I and III in three different air treatment modes.
    手术室的平面布局为污物回收型。因为此类型在目前国内手术室平面设计中约占百分之95以上。在这种设计布局中,手术室净化装修一般位于平面的内区,即位于洁净走道和污物走道之间,所以空调负荷特性相对稳定。手术室净化装修中,手术室位于综合楼二楼(共5层),层高为5m,手术室净化装修的吊顶净高为3m。Ⅰ级手术室净化装修面积为45m2(6×7.5),Ⅲ级手术室面积为35m2(5×7)。手术室墙、顶结构主要为50mm方钢龙骨结构+9.5mm石膏板+1.2mm电解钢板。
    The plane layout of the operating room is dirt recovery type. Because this type accounts for more than 95% of the current graphic design of operating rooms in China. In this design layout, the purification and decoration of the operating room is generally located in the inner area of the plane, that is, between the clean corridor and the dirt aisle, so the air conditioning load characteristics are relatively stable. In the purification and decoration of the operating room, the operating room is located on the second floor of the complex building (5 floors in total), with a storey height of 5m, and the clear ceiling height of the purification and decoration of the operating room is 3M. The purification and decoration area of grade I operating room is 45m2 (6 × 7.5), and that of grade III operating room is 35m2 (5 × 7). The wall and top structure of operating room is mainly 50mm square steel keel structure + 9.5mm gypsum board + 1.2mm electrolytic steel plate.
    (1)室外、室内空调计算参数。
    (1) Outdoor and indoor air conditioning calculation parameters.
    (2)室内散热量计算。
    (2) Indoor heat dissipation calculation.
    (3)空调冷负荷对比。
    (3) Air conditioning cooling load comparison.
    (4)手术室净化装修三种处理方式空气处理状态点参数列表(新风处理点,机器露点、送风状态点的温度、相对湿度、焓值)。
    (4) The operating room purification decoration three kinds of treatment mode air treatment state point parameter list (fresh air processing point, machine dew point, supply air state point temperature, relative humidity, enthalpy value).
    从以上计算结果对比可以看出,相同面积相同级别的净化手术室,手术室装修采用方式一的空调系统处理方式,运行能耗高,手术室净化装修采用方式三的空调系统处理方式,运行能耗低。
    From the comparison of the above calculation results, it can be seen that for the purification operating room with the same area and the same level, mode I air conditioning system is adopted for the purification and decoration of the operating room, with high operation energy consumption. Mode III air conditioning system is adopted for the purification and decoration of the operating room, with low operation energy consumption.
