Description
Technical field
The present invention relates to the energy saving upgrade techniques for being directed to VAV (Variable Air System) variable air volume system, especially relate to
And the energy conserving system and method implemented in VAV system by wireless sensor network.
Background technique
VAV system is a kind of variation that parameter can be required according to indoor load variation or interior, automatically adjusts air-conditioning system
Air output, so that room parameter be made to reach the all-air air conditioning system of requirement.VAV system, which is pursued, meets room with less energy consumption
The requirement of interior air environment.Its system control principle is: wind volume varying controller and room temperature controller constitute indoor tandem control together
System, uses room temperature for main control quantity, and air mass flow is auxiliary control amount.Wind volume varying controller is according to room temperature sensor
The actual temperature detected, the difference compared with set temperature export the adjustment signal of institute's required airflow with this, adjust vav terminal
Air-valve, change air output so that room temperature is maintained at setting range.Meanwhile in duct pressure sensor detection air duct
Pressure change is adjusted using PI or PID, by the revolving speed of Frequency Converter Control air quantity variable air conditioner machine pressure fan, eliminates pressure wave
Dynamic influence maintains air output.
The common control mode of VAV air-conditioning system includes CPC control, Static pressure reset control and total air volume control.It is wherein fixed
Under the premise of Static prestressed-pile guarantees in system air duct certain point (or several points average) static pressure is certain, indoor institute's required airflow is by VAVBOX
Air-valve is adjusted；The difference control frequency converter work of system air output definite value as set by static pressure in air duct and the point adjusts rotation speed of fan
It determines.Simultaneously, thus it is possible to vary supply air temperature requires to meet indoor comfort.Static pressure reset control to the greatest extent may be used in guarantee VAVBOX air-valve
Energy is in fully open position (85-100%), and system air output is controlled frequency converter work by static pressure required in air duct, adjusts wind
Machine revolving speed determines.Simultaneously, thus it is possible to vary supply air temperature requires to meet indoor comfort.And total air volume control is by changing air-supply
Amount adjustment room temperature, and air-supply and the difference of return air are kept constant, to meet the needs of structures air draft.
Building are usually divided into fixed region by traditional VAV system, each region use one or several VAV terminals with
Regional temperature is control object, is controlled according to regional temperature set point.Each VAV terminal is connected and fixed the ventilation opening of quantity
To cover certain area, ventilation opening is generally uncontrollable.

High-grade office building is typically all that VAV air-conditioning system is refused to use FC+ fresh air system as conventional indispensable system, " allows FC
Come back in hotel and go " be exactly such case best conclusion.The development trend of domestic high-grade office building also will be VAV system
System, because VAV system all has unrivaled superiority at technology, economy, flexibility, the small several aspects of maintenance.It has
Huge advantage rapidly develops in the world.30% share of the world Yi Zhan air-conditioning system at present, and become the certainty of Air-conditioning Development.
Foreign countries' skyscraper utilization rate is up to 95% at present.
But current this tradition VAV system haves the shortcomings that following:
1, control is inflexible, be easy to cause energy dissipation, especially in the case where nobody or people are seldom, system cannot
It is automatically closed or adjusts set point.Some legacy systems using infrared technique perception whether someone, but can not usually provide people
The approximate number of member can not do further system control and optimization.
2, when across different zones boundary, due to the difference of set point, it will usually cause trans-regional temperature instantaneous variation, make
Variation must be experienced.
3, traditional regional temperature set point is the relatively fixed value from BAS or locally manually adjusted, is not accounted for
Different adaptability of the different crowds such as old man, children and person between twenty and fifty to regional temperature.

For the sum of products divided by the sum of weight, the temperature set-point of beaconing nodes is the temperature set-point of corresponding each mobile node
With the weight sum of products divided by the sum of weight, the weight of beaconing nodes is that the sum of the weight of corresponding each mobile node is removed
With mobile node quantity；
Secondly calculate the controlled temperature and temperature set-point of VAV terminal: the controlled temperature of VAV terminal is corresponding every
For the temperature and the weight sum of products of a beaconing nodes divided by the sum of weight, the temperature set-point of VAV terminal is corresponding every
The temperature set-point and the weight sum of products of a beaconing nodes are divided by the sum of weight.Each VAV terminal is calculated in central node to answer
During the temperature set-point and controlled temperature of use, removable node is allowed to participate in the more of corresponding same VAV terminal
The operation of a beaconing nodes.
It further include that user preset and system manager preset two steps before implementing this method.For user preset, user
Corresponding temperature set-point is arranged to each removable node on central node by user interface, and by central node according to
System setting judges whether the setting of user is reasonable.Default for system manager, system manager is created by central node
Removable node and assigned identification number and weighted value are arranged the range of the temperature set-point of removable node, system model are arranged
Refrigeration or the function of heating, and conflicted and handled by possible setting between the removable node of central node detection.
