Completion time of project, be also a vital task.
At present, main flow medical treatment ventilation equipment uses way flow clean technology.Way flow, also known as " laminar flow ", refers to by sky
The air-flow that the direction of air purifying apparatus or clean area is consistent and streamline is almost parallel.The Rule of judgment of way flow is: by cleaning
The streamline in district and the deviation of ideal line are less than 14 °.But, up-to-date medical research data show, way flow air-supply operation
Room has higher postoperative infection risk.And, overwhelming majority way flow air cleaning system all uses central air-conditioning pattern, its
Disadvantageously, operation energy consumption is big, pipeline length (airduct, air-conditioning cold water pipe), valve is many, control system is complicated.
Additionally, medical treatment air conditioning system majority uses central fresh air handling (dehumidifying, homoiothermic) and filters at present, circulated air is often
Between operating room all individual processing, processing mode is divided into " primary retirn air " or " first and second return air "." primary retirn air " refers to operating room
Return air is all mixed and fed into required new wind that Cycle Unit carries out dehumidifying, homoiothermic and filtration etc. process；" first and second return air " is
Refer to a part of return air of operating room and required new wind be mixed and fed into the surface cooler of Cycle Unit carry out after dehumidifying the most again with remain back
Wind mixes and carries out the process such as homoiothermic and filtration." primary retirn air " system is simple, but all return air all removes through Cycle Unit
Reach machine dewpoint temperature (usually less than 16 DEG C) after wet, the most also need heating to reach wind pushing temperature, thus cause " cold ",
" hot " offsets, and has not only wasted cold but also consumption of calorie, the most energy-conservation." first and second return air " system can reach energy-conservation effect, but
Need to increase automatic regulating valve and actuator to realize automatically controlling, cause the most often fault rate height, tune
Examination difficulty is big, causes this system Difficulty.
It addition, in air circulation system, need to be sufficiently mixed new wind and treated return air, be delivered back into the most again
In room.If mixing uneven, then will directly affect the air quality of output wind, the such as oxygen content of local output wind on the low side
Or temperature is higher.But new wind is due to often considerably higher than return air has through process such as dehumidifying, homoiothermic humidification and purifications
Pressure head (or claim blast) and correspondingly there is more high wind speed, therefore when directly new wind different for blast and return air being mixed,
It is difficulty with uniformly mixing.And if the two is mixed in preposition pipeline in advance, then one needs longer mixing duct, two
Carry out the new wind of high-head and tend to interfere with the forward flow of low-head circulated air, even make low-head circulated air flow backwards, what is called i.e. occurs
" gas blocks up " phenomenon.Therefore, in the prior art, avoid directly merging new wind and the circulated air that transmission pressure head differs greatly the most as far as possible
Conveyance conduit, but first pressure head to them remerges two conveyance conduits after being adjusted, but this also causes significantly
The cost improved.
