Design scheme of clean air conditioning unit in 100 operating room
Operating room, purifying air-conditioning unit, 100-level design plan -- 100 operating room purifying air-conditioning unit design plan, cleanliness guarantee: through five-level filtration, new wind unit initial and middle efficiency, sub-high efficiency, air conditioning unit medium efficiency filtration, air supply end high efficiency filtration, In particular, air filters have a filtration accuracy of 0.9997 for μ ≥ 0.3 μm particles, ensuring that μ ≥ 0.5 μm particles can be fully filtered out, thus ensuring the cleanliness requirements of the operating room.
1、 100 operating room purification air-conditioning unit adopts the German imported Robert medical hygiene air-conditioning unit. Other purified air-conditioning units use Sino-British joint venture Tianjia medical hygiene air-conditioning units.
2、 positive and negative pressure switching operating room adopts a drag and drop two ways, a medical hygiene type air-conditioning unit is used alone.
3、other Class III operating room adopts one dragging two or one dragging three ways, 2-3 operating rooms use a medical hygiene type air-conditioning unit.
4、 the clean corridor and its auxiliary room adopts a medical hygiene type air-conditioning unit, adopts the efficient air supply, the top send the side back.
5、 the dirt corridor and its auxiliary room adopts a medical hygiene type air-conditioning unit, using sub-high efficiency air outlet to send the upper side back to the top.
6、operating room new wind adopts centralized control method, a total of two new wind units, new wind system with initial effect, medium efficiency, sub-high efficiency filter.
7、 exhaust system adopts independent exhaust form.
8、Each cycle unit is equipped with an electric heating humidifier and an auxiliary electric heater.
9、the guarantee of the new wind:
(1) The amount of fresh air must meet the sanitary requirements of indoor personnel;
（2）the new wind quantity needs to meet the requirements of the clean operating room fresh air change times;
（3）The difference between the amount of fresh air in the room and the amount of exhaust in the room should ensure the positive pressure value of the room;
（4）The new wind volume should meet the minimum wind volume stipulated in the "Technical Standard for the Construction of the Hospital Clean Surgery Department."
10、the amount of new wind volume: After calculating the maximum required above, provide sufficient and stable new wind through the new wind unit, of which Class I takes 1000 <UNK> / H, Class II, Class III takes 800 <UNK> / H, Corridor and auxiliary room take 4 / H.
11、 the number of room air exchange(wind volume) guarantees: the wind volume of the room is strictly in accordance with the "hospital clean surgery construction technical specification"(2002) standards to calculate, the unit motor uses frequency converter control, ensure the wind volume of each room index.
12、 the guarantee of cleanliness: Through the five-level filtration, the new wind unit primary and secondary efficiency, sub-high efficiency, the air conditioning unit medium efficiency filtration, the high efficiency filter at the end of the air supply, especially the high efficiency filter, the filtration accuracy of μ ≥ 0.3 μm particles reached 0.9997, This ensures that the particles of μ ≥ 0.5 μm can be fully filtered out, thus ensuring the cleanliness requirements of the operating room.
13、 the guarantee of room humidity: The determination of room humidity is induced by the backwind probe, the DDC system controls the humidity according to the actual humidity of the operating room, and the air is humidified by the electric heating humidifier in winter. In summer, the new return air is dehumidified by the watch cooler of the air treatment unit. The humidity requirements are detailed in Table A-A.
14、Bacterial concentration is also guaranteed if all the above indicators are guaranteed.
15、Room noise indicator guarantee: calculate the type of wind selection machine according to the resistance, and then according to the fan noise on the air conditioning unit sent back to the air duct each set of hygienic muffler to ensure noise indicator.
