Specific implementation mode
In order to further understand the content, features and effects of the present invention, the following examples are hereby given, and coordinate attached drawing Detailed description are as follows:
Fig. 1-2, a kind of integrated vehicle air-conditioning unit test device are referred to, innovative point is:Include mainly Outlet air test box, multiple outlet air plenum chambers, thermocouple case, large barometer, by data collecting instrument and test data processing unit structure At test data collection processing unit.
Multigroup outlet air test cell is integrated in outlet air test box 1, outlet air test cell is used to measure the wind of corresponding branch The pressure difference of amount.Every group of outlet air test cell further preferably centrifuges wind by blast pipe 1-1, V cone 1-2, discharge pipe 1-3, frequency conversion Machine 1-4 is sequentially connected composition.The port of blast pipe forms the air inlet interface end of outlet air test cell.Respectively draw at the both ends of each V cones Go out a test point, both ends test point connects with being arranged to be respectively formed gas in two test sides of external differential manometer and lead to, specifically, logical It crosses two plastic flexible pipes to export the correspondence gas pressure of both ends test point, two detections is detected by two test sides of differential manometer The gas pressure of point obtains the pressure difference of V cones with this.Differential manometer and the connection at the both ends bored V do not illustrate in the accompanying drawings.It is above-mentioned V cones can also be used nozzle substituted.
Multiple outlet air plenum chambers 2 are consistent with outlet air test cell group number, and the input end of multiple outlet air plenum chambers passes through pipeline Connect one by one with each air outlet of vehicle air conditioning unit respectively, the outlet ends of multiple outlet air plenum chambers by pipeline respectively with The air inlet interface end of multigroup outlet air test cell connects one by one, and a static pressure transducer is mounted in each outlet air plenum chamber, The effect of static pressure transducer is:Perceive the air pressure in plenum chamber.After data collecting instrument acquires plenum chamber inner air pressure, subtract It is used as static pressure after removing atmospheric pressure.Static pressure generally sets 0Pa, when vehicle air conditioning unit is started to work, plenum chamber Interior pressure superatmospheric power, static pressure are more than 0Pa, and frequency conversion centrifugal blower is started to work, when reaching a certain frequency, static pressure Stabilization fluctuates above or below 0Pa.
Multiple test input interfaces and multiple test output interfaces, a test input interface pair are provided on thermocouple case Should be in an air outlet of vehicle air conditioning unit, and test input interface and connected by thermocouple wiring with corresponding air outlet It connects.The effect of thermocouple case, which is arranged, is:By thermocouple wiring, each duct outlet of vehicle air conditioning unit is perceived The temperature at place.
Large barometer is for detecting outlet air test box ambient exterior atmospheric pressure.
Data collecting instrument is for acquiring multiple pressure difference output signals, thermocouple detection output signal, static pressure detection output letter Number and atmospheric pressure detect signal, test data processing unit is for handling the output signal of data collecting instrument.
Above-mentioned differential manometer, large barometer and test data collection processing unit are further preferably installed concentratedly in Electric Appliance Cabinet In, Electric Appliance Cabinet is set to outside outlet air test box.And thermocouple case is placed in vehicle air conditioning unit neighbouring position.
On the basis of above-mentioned integrated vehicle air-conditioning unit test device, in the air inlet of vehicle air conditioning unit It is further provided with inlet air temperature detection piece at mouthful, for example uses thermometer.Vehicle is can measure by the inlet air temperature detection piece The inlet air temperature of air-conditioning unit.In the case where vehicle air conditioning unit is in defrosting or blows foot operating mode, by vehicle sky The inlet air temperature of controlled atmosphere section unit, vehicle air conditioning unit blow foot air outlet temperature or Defroster Outlet temperature is transferred to survey Data acquisition process unit is tried, it can be achieved that the test that heating performance is tested.And it is in blow head work in vehicle air conditioning unit Under pattern, the inlet air temperature of vehicle air conditioning unit, the blow head air outlet temperature of vehicle air conditioning unit are transferred to survey Try data acquisition process unit, it can be achieved that refrigeration performance experiment test, to extend this integrated vehicle air conditioning list The test function of first test device.
The quantity of above-mentioned outlet air test cell is more preferably 15 groups;The quantity of above-mentioned outlet air plenum chamber is further preferred It is 15.Using the preferred embodiment of 15 groups of outlet air test cells and 15 groups of outlet air plenum chambers, existing vehicle air can be met and adjusted The once mounting of most 15 air outlets of unit detects.And when the quantity of the air outlet of the air-conditioning unit of vehicle is less than 15 When, the selection use of respective numbers is carried out from 15 groups of outlet air detection units.
Above-mentioned that a temperature sensor is also further fitted in each outlet air plenum chamber, the detection of temperature sensor is defeated Data collecting instrument will be equally transferred to by going out signal.Temperature sensor is arranged in outlet air plenum chamber to act as:Perceive vehicle air Each duct outlet for adjusting unit passes through the mixed air themperature of nature.
Below by taking the automotive air-conditioning system of existing most air outlets (15 air outlets) as an example, this integrated form is illustrated Vehicle air conditioning unit test device operation principle:
After air conditioning for automobiles and its air duct install, apply 4 to 12V a certain numerical value DC voltage, air blast to air blower Machine operating generates air quantity.According to test requirements document, interior outer gas air door, changes in temperature air door rotate to the position of a certain requirement, pattern air door Rotate to blow head respectively, blow head blows foot, blows foot, full blow, blows foot defrosting, defrosting one of six positions, then test tested sample The air quantity of each air outlet of part.Air flows through defrosting duct by test specimen, by three roads, blow head air duct, blows foot air duct, each Air duct separates 5 air ports.Air flows to a plenum chamber by each air port again.It is total in this way to separate 15 accesses.Every access Air, by hose flow into an outlet air test cell, finally from frequency conversion centrifugal blower exclude air.
Collected atmospheric pressure data, V cones pressure difference data, temperature data, static pressure data are inputed to survey by data collecting instrument Data processing unit is tried, the ratio data report that each air outlet air quantity accounts for total blast volume is obtained after data processing;And it is each A air outlet temperature, as the position of changes in temperature air door is from minimum aperture to maximum opening, test obtains each air outlet temperature, so The linear data of changes in temperature damper positions and air outlet temperature is formed afterwards.Thus allocation of the amount of air experiment and temperature linearity are tested same When can complete.
In no testing stand (this integrated vehicle air-conditioning unit test device), allocation of the amount of air is tested at one The rack for exclusively carrying out wind quantity test is completed.Temperature linearity experiment is completed on another enthalpy difference experiment platform.If to automobile sky It adjusts, after the air duct progress structure change that air-conditioning connects below, needs to be tested respectively, test efficiency is very low.Develop this examination After testing platform, test efficiency is greatly improved, shortens the development cycle.
