Description
Technical field
The present invention relates to Heating,Ventilating and Air Conditioning technical fields, and in particular to a kind of Temperature and Humidity Control and indoor pollutant concentration purification
Control mutually independent extrusion type air-conditioning system.
Background technique
There are about 90% times to spend indoors by people, thus how to build the indoor air quality for representative into
Row effectively control is then of great significance.And architecture indoor is often using air-conditioning box as Cooling and Heat Source with one of temperature and humidity control system
Variable air volume system (VAV system).As shown in Figure 1, in the prior art often in contact with to a kind of air-conditioning box structure type show
It is intended to, which disclose a kind of extrusion type air-conditioning box structures, for just effect surface air cooler 24, heater 25 and humidifier 26,
Frequency conversion fan 22 is in front end.
Still further aspect, with the continuous growth of the pollutant purifications market demand such as indoor PM2.5, formaldehyde, at present
The structure of air-conditioning box with purification function has also occurred, and is illustrated in figure 2 a kind of extrusion type air-conditioning with air-cleaning function
Box structure schematic diagram increases medium/high effect purification device 23, and the medium/high effect purification dress relative to each component in Fig. 1
Setting can be before frequency conversion fan 22 or after frequency conversion fan 22.
In addition, it is contemplated that dynamical problem, it is adjusted in extrusion type air-conditioning box structure basis shown in Fig. 2, it will be in Fig. 2
Medium/high effect purification device 23 be adjusted in Fig. 3 with frequency conversion fan 32 and it is medium/high effect purification device 33 clean unit 300,
Wherein, medium/high effect purification device 33 can be before frequency conversion fan 32 or after frequency conversion fan 32.
The control logic of Fig. 2 and the air conditioner box system shown in Fig. 3 with air-cleaning function (or air cleaning member)
It is as follows:
1, from Temperature and Humidity Control demand analysis, Wind Volume, the i.e. processing of increase cooling and heating load are used when indoor/outdoor temperature-difference is big
Amount；Small air quantity, i.e. reduction cooling and heating load treating capacity are used when indoor/outdoor temperature-difference is small.
2, it is analyzed from pollutant purification demand for control, when pollutant concentration is high, using Wind Volume by purification device, i.e.,
Increase purified treatment amount；Purification device, i.e. reduction purified treatment amount are passed through using small air quantity when pollutant concentration is low.
Air quantity variation is adjusted that is, the control of cooling and heating load treating capacity and pollutant purification amount is all made of blower variable speed
Section control, but actually temperature and humidity processing is often different from the regulatory demand of pollutant purification, and the demand to rotation speed of fan is not yet
Together.Since air conditioner box system is all made of temperature signal control rotation speed of fan in the prior art, i.e., wind is controlled according to cold-heat treatment amount
Machine air output.When carrying out indoor temperature and humidity adjusting simultaneously using this control model and pollutant purification is handled, will generate
Problem.Such as the mild weather of outdoor air pollution, cold-heat treatment demand air quantity is smaller, pollutant purification demand air quantity is larger, but
According to cold-heat treatment desired signal, air-conditioning box is run with small air quantity, will cause that pollutant purification amount is less than normal, and clean-up effect is paid no attention to
Think, is unable to the risk of effective guarantee indoor air quality.
That is, extrusion type air-conditioning system in the prior art can not be to cold-heat treatment demand and pollutant purification demand
Air quantity coordinated control.
Summary of the invention

When meet cold-heat treatment, pollutant purification processing and maintain indoor wind balance needed for air quantity.When pass through temperature and humidity processing unit
Air quantity demand it is small, big by the air quantity demand of purification assembly when, after air purified component processing, a part passes through temperature and humidity
Indoor or wind outlet section is sent into after processing unit processes cooling and heating load, another part is sent into indoor or wind outlet section by bypass air hose,
To realize the independent control of temperature and humidity and pollutant purification.Volume damper (or volume damper is set in the bypass air hose
And frequency conversion fan), it is net to meet indoor temperature and humidity control and pollutant under full working scope to adjust air output size according to demand
The demand of change.Further, the exhaust air rate to maintain indoor wind balance required is discharged to outdoor by exhaust pipeline.
It will be further detailed below by specific embodiment.
Embodiment 1:
Mutually independent extrusion type is controlled with indoor pollutant concentration purification as shown in figure 4, providing a kind of Temperature and Humidity Control
Air-conditioning system.Its structure is as follows:
Including the purifying treating unit being made of primary filter 1, frequency conversion fan 2 and medium/high effect purification device 3, and
The temperature and humidity processing unit being made of surface air cooler 4, heater 5 and humidifier 6；In purifying treating unit and temperature and humidity processing unit
Between supervisor's pipeline on draw bypass line 7 as tap line along air-flow D to air supply section 9 or interior, and the main road of supervisor is then
For air-flow via purifying treating unit again through temperature and humidity processing unit along air-flow B to air supply section 9 or interior, and then make two strands of air-flows
(air-flow B and air-flow D), which converges to air supply section 9 or interior or both, all to be had.Wherein, for the ease of adjusting air quantity, in bypass line 7
On be additionally provided with volume damper 8.Air-flow D is sent into interior after can mixing with air-flow B through air supply section 9, can also be individually by air-supply branch
Pipe 13 is sent into interior.
On the other hand, from indoor air-flow F through return air stream C in 10 part forming chamber of air return pipeline enter supervisor after again
Purified treatment (or converging with fresh air air-flow A latter with via purifying treating unit), air-flow F are completed via purifying treating unit
Another part then formed maintain indoor wind balance needed for exhaust air rate air-flow E outdoor is discharged along exhaust pipeline 11.
That is, this extrusion type air-conditioning system may be implemented after fresh air air-flow A is mixed with indoor return air air-flow C by primarily efficient filter
After device 1, frequency conversion fan 2, the processing of medium/high effect purification device 3, a part is using surface air cooler 4, heater 5, the processing of humidifier 6
Air-flow B, another part are arrived afterwards by bypass line 7, volume damper 8 to air-flow D, subsequently into air supply section 9 or interior.With
And outdoor is discharged to by exhaust pipeline 11 for the exhaust air rate air-flow E for maintaining indoor wind balance required.It can be indoor according to meeting
The Bu Tong flexibly control of temperature and humidity and air quantity required for pollutant concentration demand for control.
Temperature and Humidity Control provided by the invention controls mutually independent extrusion type air-conditioning system with indoor pollutant concentration purification,
