Description
Technical field
The utility model belongs to the purification ventilating system, is specifically related to a kind of clean operating room purification air-conditioning Intelligentized regulating and controlling system.
Background technology
For hospital's class building, central air-conditioning system is all adopted in the design of its air-conditioning system at present.Because the environment cleanliness of many departments of hospital requires than higher, so the ventilation amount in its room is the several times in common air-conditioning room, particularly high-level clean operating room, ventilation rate hourly is from tens times to over one hundred time.In addition, the air-out end at clean operating room also will be provided with highly effective air (HEPA) filter specially.Because it is rate of ventilation is more and air cleaner has sizable circulating resistance, therefore single just quite big with regard to its energy consumption of operating room.The North China is by GB GB50333-2002 " Standard for daylighting design of industrial enterprises " regulation 40m
2I level clean operating room, to move 8 hours every day, operation in a year was calculated in 300 days, and the power consumption in 1 year surpasses 50,000 degree.
The working hour of operating room can be divided into roughly that operation is prepared, operation is carried out, postoperative cleaning arrangement and for use on duty etc. to next operation.In the different periods, personnel amount, equipment, light load in the operating room are widely different.Except operation is carried out the stage; Generally have only the minority medical personnel to get into and arrange medicine equipment and equipment; The indoor illuminating lamp of only opening; Powerful shadowless lamp and Medical Devices all are in holding state, and indoor occupant is few, power consumption is lower, and the airfiltering circulating fan that is used for that especially energy consumption is bigger need not to open.Even carry out the stage in operation, infect probability when otch begins to sew up and descend, circulating fan also can be out of service.Medium-sized in addition and related medical personnel and the equipment of major surgery does not wait, and required load difference is also bigger.But when doing Air-conditioner design for operating room, calculate according to the needed load of least favorable duty, generally feel colder so non-operation period medical worker gets into operating room, the high wastage of the energy is obvious.As previously mentioned; What the design of hospital's air-conditioning system was adopted is central air-conditioning system; Operating room belongs to the part in the air-conditioning networking; Though operating room is the big power consumer of hospital, the control of room conditioning operation self only has operation, stop and temperature, humidity display, and big adjustment can only submit to power department that air conditioning purge ventilation unit is regulated like need.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art; Provide a kind of pairing actual load needs of different operating period according to clean operating room to change the air-conditioning system (vav) of air quantity, thereby carry out the clean operating room purification air-conditioning control system of Intelligentized regulating and controlling.
The purpose of the utility model is achieved in that
Clean operating room purification air-conditioning control system; Comprise aseptic clean room and assembled air-conditioner unit, wind circulating system, exhaust system and fresh air supply system; It is characterized in that: but electronic adjusting valve A5 is installed in new wind air channel, frequency conversion fan is installed in the circulated air air channel; At exhausting duct but 1～2 electronic adjusting valve B6 is installed, but but described electronic adjusting valve A, frequency conversion fan and electronic adjusting valve B are connected with processing unit respectively.
Compared with prior art, advantage of the utility model and good effect are:
1, can be set at multiple typical condition respectively according to type of surgery or course of work difference; The unit of controlling through in the operating room is preset and is regulated circulation air output and resh air requirement; The driving energy consumption of blower fan and the cold and hot energy consumption of new wind have effectively been reduced; Reduced operating cost, the energy-saving effect highly significant.
2, when control, need not have senior professional knowledge, simple to operation.
