Kitchen ventilator Testing Platform of the present invention is for calculating the practical contaminant removal efficiency of kitchen ventilator under each operating mode.Its
Computing Principle is that equivalent source strength when distributing source strength by the way that test contaminant is practical and open kitchen ventilator carries out evaluation kitchen ventilator
Actual performance.For in detail, the kitchen ventilator Testing Platform computational methods step is specific as follows：
(1) test contaminant is practical distributes source strength
When not opening kitchen ventilator, test contaminant is practical distributes source strength, and it is dense to distribute stage pollutant by analysis pollutant
The data changed over time are spent, can derive that pollutant distributes the calculating formula such as (1) institute of source strength according to mass balance equation (2)
Show：
Mass balance equation (2) expression formula is as follows：
In formula (1) and formula (2), V is the volume in region, m3；S is PM2.5 pollutant source strengths, a/h；C is region
Interior PM2.5 number concentrations, a/m3；QSIt is by the air quantity of outdoor entrance, m3/h；QnIt is the air quantity that adjacent area enters, m3/h；Cn
It is adjacent area concentration, a/m3；QiIt is the air quantity for flowing to adjacent area, m3/h；QeIt is exhaust air rate, m3/h；α is total deposition,
m3/h；P is PM2.5 penetrating coefficients, usual value 0.8.
Domain Volume is inputted by user by man-machine interaction panel in equation (1), by the pollutant natural sediment stage
The analysis of data, total deposition α are calculated by formula (3)：
(2) test contaminant equivalent distributes source strength
When opening kitchen ventilator, test contaminant equivalent distributes source strength Se, test process with test contaminant is practical distributes
Source strength is identical, but distributes stage unlatching kitchen ventilator in pollutant.
(3) the practical pollutants removal rate of kitchen ventilator is calculated
Go out that pollutant is practical to distribute source strength and pollutant equivalent distributes source strength by experiment test twice, utilizes formula (4)
Calculate the practical pollutants removal rate of kitchen ventilator.
A specific embodiment is set forth below, the present invention will be described：
An ordinary residence is chosen as carrier is illustrated, which is provided with exterior window, and the other side is provided with inside door.
PM2.5 sensors and wireless transport module link together on the outside of kitchen ventilator, close to cook respiratory region, for surveying
Try the pollutant concentration near cook respiratory region.Microprocessor and man-machine interaction panel are mounted on kitchen wall.
Volume (the 8.7m in kitchen is inputted by man-machine interaction panel using the system initial stage, residential customer3), it is calculating
Pollutant is practical when distributing source strength, closes kitchen exterior window and inside door, builds a closed environment.The test process includes ten
Minute pollutant distributes the stage, then terminates pollutant and distributes the progress pollutant natural subsidence stage.Pass through in the present embodiment
The process that the pollutant for distributing source strength simulates practical culinary art activity generation pollutant of stablizing is generated on kitchen range.PM2.5 is passed
Sensor is distributed pollutant by wireless transport module and pollutant concentration changes over time in the two stages of natural subsidence
Data transmission to kitchen ventilator Testing Platform, kitchen ventilator Testing Platform first carries out the pollutant natural subsidence stage
Analysis calculates total deposition by formula (3), and Fig. 3 (a) shows its fit procedure, using the total deposition being calculated as
Known quantity is brought into formula (1).Kitchen ventilator Testing Platform distributes the stage to pollutant at this time and analyzes, according to formula
(4) calculate that pollutant is practical to distribute source strength, Fig. 3 (b) shows fitting source strength process.So far it obtains practical pollutant and distributes source
By force (6.12 × 1010A/h), kitchen ventilator Testing Platform distributes this in source strength data transmission to microprocessor.
After obtaining practical pollutant and distributing source strength, the test of equivalent source strength when unlatching kitchen ventilator is carried out.According to concern feelings
The difference of shape can divide different operating modes, the present embodiment kitchen to have a fan exterior window and a fan inside door, therefore according to the switching group of door and window
Closing can be there are four types of different operating mode, but while getting used to culinary art for the user opens kitchen inside door, therefore it is outer to only focus on closing
Window and both operating modes of unlatching exterior window.
When the pollutant equivalent that test is closed under exterior window and unlatching inside door operating mode distributes source strength, process is similarly ten
The pollutant dissemination process of minute, and keep kitchen ventilator to be in open state in the process.PM2.5 sensors are by wirelessly passing
The data transmission that defeated module changes over time pollutant concentration in time period to kitchen ventilator Testing Platform, also with
Formula (1) calculates equivalent pollutant and distributes source strength, and Fig. 3 (c) is to close equivalent pollutant under exterior window unlatching inside door operating mode to distribute
Source strength fit procedure.So far it calculates the equivalent pollutant closed when exterior window opens inside door and distributes source strength (3.35 × 1010A/h).
Kitchen ventilator Testing Platform distributes equivalent pollutant in source strength data transmission to microprocessor, and microprocessor combines practical dirty
Dye object distributes source strength data, and it is 45.3% to calculate the practical pollutants removal rate of kitchen ventilator under the operating mode using formula (4), and will
The removal rate is shown by man-machine interaction panel, and kitchen ventilator actual performance evaluation index parameter is provided for residential customer.
Fig. 3 (d) be open exterior window open inside door when equivalent pollutant distribute source strength calculating fit procedure, also according to
It is 2.72 × 10 that upper experimental procedure, which calculates equivalent pollutant source strength under the operating mode,10A/h.Source strength is distributed in conjunction with practical pollutant
Data value, it can be deduced that the practical pollutants removal rate of kitchen ventilator is 55.6% under the operating mode, to evaluate kitchen ventilator in the operating mode
Actual performance under (opening exterior window, open inside door).
The practical contaminant removal efficiency of calculated kitchen ventilator under different operating modes is transferred to human-computer interaction face by microprocessor
Plate is shown, it is preferable that by comparing the practical contaminant removal efficiency of kitchen ventilator under different operating modes, is provided residential customer and is being cooked
The operating mode suggestion used when preparing food suggests that residential customer opens kitchen exterior window in culinary art, with this maximum oil if the present embodiment
Smoke machine performance.
It should be understood that embodiment and example discussed herein simply to illustrate that, to those skilled in the art
For, it can be improved or converted, and all these modifications and variations should all belong to the protection of appended claims of the present invention
