Description
Technical field
The present invention relates to for the energy-conservation upgrade technique of VAV (Variable Air System) variable air volume system, especially relating to
And the energy conserving system implemented in VAV systems by wireless sensor network and method.
Background technology
VAV systems are a kind of changes that can require parameter according to indoor load change or interior, automatically adjust air conditioning system
Air output, so that room parameter reaches the all-air air conditioning system of requirement.VAV systems are pursued and meet room with less energy consumption
The requirement of interior air ambient.Its system control principle is：Wind volume varying controller and room temperature controller constitute indoor tandem control together
System, adopts indoor temperature for main control quantity, and air mass flow is auxiliary controlled quentity controlled variable.Wind volume varying controller is according to room temperature sensor
The actual temperature for detecting, compares difference with design temperature, exports the adjustment signal of Air Quantity Required with this, adjusts vav terminal
Air-valve, change air output so that indoor temperature is maintained at set point.Meanwhile, in duct pressure sensor detection air channel
Pressure change, is adjusted using PI or PID, by the rotating speed of Frequency Converter Control air quantity variable air conditioner machine pressure fan, eliminates pressure wave
Dynamic impact, maintains air output.
The conventional control mode of VAV air conditioning systems includes CPC control, Static pressure reset control and total air volume control.Wherein fixed
On the premise of Static prestressed-pile ensures certain point in system air channel (or some is average) static pressure is certain, indoor Air Quantity Required is by VAVBOX
Air-valve is adjusted；Difference control converter work of the system air output by static pressure in air channel with the definite value set by point adjusts rotation speed of fan
Determine.Simultaneously, thus it is possible to vary wind pushing temperature come meet indoor comfort requirement.Static pressure reset control to the greatest extent may be used in guarantee VAVBOX air-valves
Can in fully open position (85-100%), system air output static pressure needed in air channel controlling converter work, adjusts wind
Machine rotating speed determines.Simultaneously, thus it is possible to vary wind pushing temperature come meet indoor comfort requirement.And total air volume control is blown by changing
Amount adjustment indoor temperature, and make air-supply keep constant with the difference of return air, to meet the demand of structures air draft.

Come back to and go in hotel " the best conclusion of exactly such case.The development trend of domestic high-grade office building will also be VAV systems
System, because VAV systems all have unrivaled superiority at technology, economy, motility, the little several aspects of maintenance.It has
Huge advantage, develops rapidly in the world.30% share of current Yi Zhan worlds air conditioning system, and become the certainty of Air-conditioning Development.
Foreign countries' skyscraper utilization rate is up to 95% at present.

1st, underaction is controlled, easily causes energy dissipation, especially at nobody or in the case that people is little, system can not
It is automatically switched off or adjusts set point.Some legacy systems perceive whether someone using infrared technique, but cannot generally provide people
The approximate number of member, it is impossible to do further system control and optimize.
When the 2nd, crossing over zones of different border, due to the difference of set point, it will usually cause trans-regional temperature instantaneous variation, make
Variation must be experienced.
3rd, traditional regional temperature set point be from BAS or local adjust manually be relatively fixed value, do not account for
Different adaptabilities of the different crowds such as old man, child and person between twenty and fifty to regional temperature.

Fig. 4 shows an enforcement of the power-economizing method that implements in VAV systems by wireless sensor network of the present invention
The flow chart of example.Fig. 4 is referred to, the detailed description of the implementation steps of the power-economizing method to the present embodiment is presented herein below.
Step S1：Information, the information are sent by removable node real-time detection environment temperature and to beaconing nodes around
Including the identification number that may move node oneself and the real-time temperature values for detecting.
Removable node is embedded in the object with people's movement, and beaconing nodes are fixed on the air outlet of each VAV terminal
Position.
Step S2：The information that the removable node that surrounding is received by beaconing nodes sends, and letter is sent to Centroid
Breath, the information include the information of the identification number of beaconing nodes oneself and its all removable node for receiving.
Step S3：The information that all beaconing nodes send is received by Centroid, calculating each VAV terminal should adopt
Temperature set-point and controlled temperature, and be sent to corresponding VAV terminals and which implemented to control.
Centroid to the control that VAV terminals are implemented include control VAV terminals refrigeration or heat, by with VAV terminals
Connected vent output, to the region air feed that vent is covered, it is believed that be not received by the beacon of the signal of removable node
Near the position of node, nobody, controls corresponding VAV terminals and closes or adopt default parameterss.
In this step, can specifically be refined as calculating the scope of VAV terminals, calculate what each VAV terminal should be adopted
Temperature set-point and controlled temperature this two step.
For terminal scope is calculated, Centroid will receive the beaconing nodes of the signal of a removable node as this
The location estimation value of removable node, using the scope for being obtained removable node based on non-ranging centroid localization algorithm and is opened
VAV terminals in the range of this.
For temperature set-point and the controlled temperature that each VAV terminal should be adopted is calculated, each beacon section is calculated first
The temperature of point, desired temperature and weight：The temperature of beaconing nodes is the temperature and weight of each mobile node corresponding
Divided by weight sum, the temperature set-point of beaconing nodes is the temperature set-point of each mobile node corresponding to the sum of products
With the weight sum of products divided by weight sum, the weight of beaconing nodes is that the weight sum of each mobile node corresponding is removed
With mobile node quantity；
Secondly the controlled temperature and temperature set-point of VAV terminals are calculated：The controlled temperature of VAV terminals is corresponding every
With the weight sum of products divided by weight sum, the temperature set-point of VAV terminals is corresponding every to the temperature of individual beaconing nodes
The temperature set-point of individual beaconing nodes is with the weight sum of products divided by weight sum.Each VAV terminal is calculated in Centroid should
During the temperature set-point and controlled temperature for adopting, it is allowed to which removable node participates in many of corresponding same VAV terminals
The computing of individual beaconing nodes.
Also include user preset and default two steps of system manager before the method is implemented.For user preset, user
Corresponding temperature set-point is arranged on Centroid by user interface to each removable node, and by Centroid according to
System is arranged and judges whether the setting of user is reasonable.For system manager is default, system manager is created by Centroid
Removable node assigned identification number and weighted value, arrange the scope of the temperature set-point of removable node, arrange system model
Refrigeration or the function of heating, and conflicted and processed by possible setting between the removable node of Centroid detection.
