  • 手术室装修新风系统的选择
    来源:http://www.sdyhrs.com 浏览: 发布日期:2019-05-29
    在手术室装修中,新风系统的选择是十分重要的一步,下面小编就给大家总结一下常用的手术室新风系统的种类,希望对大家有所帮助!
    In the operation room decoration, the selection of fresh air system is a very important step. The following edition summarizes the types of fresh air system commonly used in the operation room, hoping to help you!
    1.一次回风系统
    1. Primary return air system
    这种送风方式是传统的舒适性空调送风方式。新风经过一级过滤后,与回风混合,再经过二级过滤和热湿处理,送入静压箱。该送风方式系统简单,容易保证设计要求的送风量和新风量,过度季节,可以通过设置在新风口、回风管上的风量调节阀调节回风比,从而达到节能的目的。
    This air supply mode is the traditional comfortable air-conditioning air supply mode. The fresh air is mixed with the return air after the first stage filtration, and then is fed into the static pressure box after the second stage filtration and heat and humidity treatment. The air supply system is simple and easy to ensure the required air supply and fresh air volume. In excess of season, the air return ratio can be adjusted by the air flow regulating valve installed on the new air outlet and return air duct, so as to achieve the purpose of energy saving.
    该系统的不足之处主要表现在两个方面:正压风量不容易控制,特别是多间手术室共用机组时;新风与回风混合再进行热湿处理,新风入室空气龄增加,新风效益降低,不利于室内空气品质的改善。
    The shortcomings of the system are mainly manifested in two aspects: the positive pressure air volume is not easy to control, especially when multiple operating rooms share units; the fresh air and return air are mixed and then treated with heat and humidity, the age of fresh air entering the room increases, and the benefit of fresh air decreases, which is not conducive to the improvement of indoor air quality.
    2.新风单独处理,再与处理过的回风混合,送入静压箱
    2. The fresh air is treated separately, then mixed with the treated return air and fed into the static pressure box.
    该送风方式系统比较简单,控制管理方便。新风可以集中处理,既能保证设计风量,能在过度季节增大新风量,又能控制正压风量(可采用双风量控制装置等控制方式)。另外,可根据当地气象资料和室内湿负荷的大小,控制新风机组和回风机组的干湿运行方式,譬如,湿负荷由新风机组承担,回风机组始终处于干工况运行,这样对控制空调系统的微生物孳生繁殖是有利的。
    The air supply system is simple and easy to control and manage. Fresh air can be centralized treatment, which can not only ensure the design air volume, increase the fresh air volume in excessive season, but also control the positive pressure air volume (double air volume control device can be used). In addition, according to local meteorological data and indoor wet load, we can control the dry and wet operation mode of fresh air unit and return air unit. For example, the wet load is borne by fresh air unit, and the return air unit is always operating in dry condition, which is beneficial to control the microbial breeding of air conditioning system.

    但是该方式增加了新风机组的处理量,初投资会增加;当部分手术室停运时,通过节流方式控制正压风量,不利于节能,又可能产生噪声问题;应当注意机组后新风与回风混合点压力控制问题。两机组的余压和动压不一定相同,势必会影响新风比(或回风比),当影响较大时,很难保证手术室设计要求的新风量,同时也不容易维持室内的压力,严重时将导致送风倒灌回新风机组的现象(特别是新风机停开时容易倒灌),造成手术室零新风工况,使压力梯度消失,造成手术部均压状况等现象。
    However, this method increases the processing capacity of fresh air units and the initial investment will increase. When some operating rooms are out of operation, it is not conducive to energy saving and may cause noise problems by throttling the positive air volume. Attention should be paid to the pressure control at the mixing point of fresh air and return air after the unit. The residual and dynamic pressures of the two units are not necessarily the same, which will inevitably affect the fresh air ratio (or return air ratio). When the impact is large, it is difficult to ensure the fresh air volume required by the operating room design, and it is also difficult to maintain the indoor pressure. Serious cases will lead to the phenomenon that the supply air is backfilled back into the fresh air unit (especially when the fresh air is stopped), resulting in zero fresh air operating conditions in the operating room and making the pressure ladder. Degree disappeared, resulting in the operation of the pressure balance situation and other phenomena.
    3.新风直接送入送风静压箱
    3. Fresh air is directly fed into the static pressure box of supply air
    这种送风方式在手术室空调中还未普遍应用。新风送入静压箱,即手术室层流罩,这种层流罩自带风机,所需风机压头较小,但由于风机置于手术室顶层(即手术室吊顶层内),需注意噪声的控制;层流罩内自带均流板,需增加新风与回风混合段,层流送风装置较高,受室内层高限制;室内热、湿负荷全部由新风负担;空调方式结构简单,造价较底。
    This kind of air supply method has not been widely used in air conditioning of operating room. Fresh air is fed into the static pressure box, i.e. the laminar flow hood in the operating room. This kind of laminar flow hood has its own fan with smaller pressure head, but because the fan is placed on the top floor of the operating room (i.e. in the ceiling floor of the operating room), attention should be paid to noise control; the laminar flow hood has its own flow equalizer, which needs to increase the mixing section of fresh air and return air, and the laminar flow air supply device is higher, which is limited by the height of the indoor floor; the indoor heat and humidity load is all limited by the height of the Fresh air burden; air conditioning mode has simple structure and low cost.
    这种送风方式因新风负担室内全部热、湿负荷,夏季新风处理的露点温度较低,才能满足室内热、湿负荷要求。同时需考虑新风机组的除湿、凝结水的排除,与回风需充分混合等问题。
    Because fresh air bears all indoor heat and humidity load, the dew point temperature of fresh air treatment in summer is lower, which can meet the indoor heat and humidity load requirements. At the same time, the dehumidification of fresh air unit, the removal of condensate water and the need for full mixing with return air should be considered.
