Can operation room ventilation adopt fan coil unit plus fresh air system to meet the requirements of purification?
In the operating room of a hospital, air conditioning is required to use fan coil unit plus fresh air system. Can this meet the purification requirements? Generally speaking, the combined air conditioning unit, fresh air through the initial effect, intermediate effect and the end of the high-efficiency filter can meet the purification requirements, if this method can be, then what kind of structure and construction technology?
Now the market is indeed a kind of FCU with purifying filter equipment, that is, fan coil end plus medium or sub-high efficiency filter, together with the fan coil fan head increased. But how can this architecture work in practice? Technically speaking, it is not advisable to choose fan coil unit plus fresh air system for purification.
Just now, the need for fan coil units to increase the pressure head, but often the effect is not good, how to deal with noise is a problem, and the replacement of filter needs reasonable planning. The problem lies in noise control and routine replacement filter maintenance, and how other sterilization and disinfection are handled.
Now, air-conditioning manufacturers have successfully developed a fan coil unit with high-grade purification function. Its characteristics are as follows:
1.装有静电除尘器 能吸附小至 0.1μm 的尘埃和病菌。经测试,该风机盘管的静电除尘设备关于≥0.5μm 颗粒除尘功率达 72%,完全能满意医院大部分科室的洁净度要求,并且6000V的静电能瞬间杀灭吸附的病菌,有用下降医院内交叉感染的几率。别的,装有活性碳过滤器,能 吸附医院内产生的臭气及其他有害化学气体(如甲醛、苯、尼古丁等)。
1. equipped with electrostatic precipitator can absorb dust and bacteria as small as 0.1 M. The test results show that the electrostatic dedusting equipment of fan-coil unit can meet the cleanliness requirements of most departments of the hospital, and 6000V electrostatic can kill the adsorbed bacteria instantly, which can effectively reduce the probability of cross-infection in the hospital. In addition, it is equipped with activated carbon filter, which can absorb hospital odor and other harmful chemical gases (such as formaldehyde, benzene, nicotine, etc.).
2.装有二氧化碳(CO2)监测器 在医院中,患者的体质都较弱,如不注意室内CO2浓度状况,一旦CO2超标将形成室内缺氧,使病况加剧或引发其他病症。装有 CO2传感器能随时监测室内 CO2浓度,当 CO2浓度超越设定值时主动报警,保证 CO2浓度不超越 1000ppm。
2. Installed with carbon dioxide (CO2) monitor in the hospital, the patient's physique is weak, if do not pay attention to the indoor CO2 concentration, once CO2 exceeds the standard will form indoor hypoxia, make the condition worse or cause other diseases. Equipped with CO2 sensor, indoor CO2 concentration can be monitored at any time. When CO2 concentration exceeds the set value, it will alarm actively to ensure that CO2 concentration does not exceed 1000ppm.
3.选用全开放式规划 传统风机盘管全封闭式规划且装置方位很高,风机盘管不能翻开,尘埃累积、 极易繁殖细菌,严峻污染室内空气,形成空调体系的二次污染,极不适合于对空气质量要求严厉的医院。而选用开放式装置后,只须悄悄一按,机门就可以翻开,机 内每一个角落都可以擦净,从根本上解决了空调体系二次污染问题。
3. Choose the full-open plan of the traditional closed fan-coil unit planning and the device orientation is high, fan-coil unit can not turn over, dust accumulation, easy to reproduce bacteria, severe pollution of indoor air, the formation of air-conditioning system secondary pollution, is extremely unsuitable for hospitals with strict air quality requirements. After selecting the open-type device, the door can be turned over and every corner of the machine can be wiped off with only a quiet press, thus solving the secondary pollution problem of the air conditioning system fundamentally.
4. Fan coil units are selected in the form of low-level devices not only for cleaning personnel to provide convenience, more importantly, can be useful to save energy, reduce hospital energy costs.
