Description
Technical field
The present invention relates to the devices of the true climatic environment of a kind of simulation, in particular to can be with analog temperature, humidity and wind speed
Minitype manual climatic chamber.
The present invention relates to a kind of device measuring fabric and Clothing Wetness And Heat Comfort, in particular to fabric kimonos can be measured
Fill the human body dummy of thermal resistance and dampness.
Background technology
At present it is known that many phjytotrons for simulating true climatic environment, be mainly used in bio-genetics,
Medicine, forestry, environmental science, herding and aquatic products, few certain applications are measured in fabric and Clothing Wetness And Heat Comfort.It is existing
Fabric and Clothing Wetness And Heat Comfort measuring device, such as using evaporation hot plate method, the device of flat band method making, it can be to fabric
Thermal resistance and dampness measure.However, it is known that these measuring devices have the disadvantages that, i.e., it is most of to carry out single heat
The measurement of resistance and dampness, can only carry out the measurement of fabric or clothes, cannot carry out wide range tune to the wind speed in measuring environment
Section, the temperature humidity range that can be measured is limited, so true climatic environment cannot be simulated, to fabric or clothing thermal resistance and wet
The practicability of resistance measurement result has certain influence.
A true test weather in order to obtain, then need to establish an artificial climatic environment.It can be to humidity, temperature
Degree, wind speed are simulated with close to true climatic environment.Under simulated person's work climatic environment, knitted using human body dummy's measurement
Object or the true thermal resistance of clothes and dampness, while it is real other science can also to be carried out using simulated person's work climatic environment
It tests.
Invention content
The object of the present invention is to provide one can adjust the gas that temperature, humidity, wind speed carry out simulation of global most area
It waits, carries out thermal resistance and the dampness measurement of fabric or clothes and other Minitype manual weathers for needing simulation climate environmental experiment
Room.Solve existing thermal resistance and dampness measuring device cannot accomplish at the same analog temperature, humidity, wind speed and be carried out at the same time fabric or
The shortcomings that person's clothes are tested.
To achieve the goals above, the present invention uses following technical scheme.
A kind of Minitype manual climatic chamber, including dummy room, temperature conditioning chamber, humidity regulation room, wind speed regulation room, blow into
Mouthful.Dummy room be include a platform that can fix dummy and test board, dummy plays the role of measuring thermal resistance and dampness；Temperature
The tubulose fin heats pipe that degree regulation room can be heated by one forms, which is led to by SCR control
The heating time for crossing the duty cycle adjustment heating tube for changing voltage, the temperature of Minitype manual climatic chamber is set to increase, by accurately counting
The temperature of Minitype manual climatic chamber can be raised to 60 DEG C of highest by calculating the heat that tubulose fin heats pipe provides；Temperature regulation section point
Further include a refrigeration system, which is mainly made of a frequency-changeable compressor, air-cooled condenser, evaporator and expansion valve.
Refrigerant R404A dry saturated gas is compressed by the compressor the superheated refrigerant steam for high temperature and pressure when passing through compressor, pass through
The exhaust pipe of the expansion valve piston of compressor enters in condenser, and the refrigerant vapour of high temperature and pressure is condensed within the condenser
For the liquid of high pressure low temperature, later this liquid in Minitype manual climatic chamber pipeline after filter by capillary, in capillary
Isenthalpic throttling becomes the refrigerant vapour of low-temp low-pressure in pipe, and then the refrigerant of this low-temp low-pressure is in isobaric evaporator
The middle steam for absorbing extraneous heat and becoming saturation, realizes the process of refrigerastion of Minitype manual climatic chamber.Last refrigerant is again
It is sucked by compressor and carries out SAPMAC method.Evaporator, which absorbs extraneous heat, makes temperature reduce, can due to the characteristic of R404A refrigerants
To be reduced to -40 DEG C by Minitype manual weather indoor air temperature is minimum.Humidity regulation room is by an electrode humidifier and confession
Water tank forms, and water enters steam generator by solenoid valve and water filling cup, inside there is two to three electrodes, when water is added, electricity
Pole is contacted with water, generally has certain conductivity in tap water, so that circuit turn-on, electric energy is converted to thermal energy, water is straight by heating
To boiling, a large amount of steam are generated, from output suitable for reading, are sent in Minitype manual weather room air by a rubber hose to reach
The purpose of humidification.Due to the high and low difference of water level, electrode slice and water engaging surface product are bigger, and generation electric current is bigger, and steam output is got over
It is more.Humidification amount by accurately calculating selected electrode humidifier the air humidity of Minitype manual climatic chamber can be humidified to
98%RH.The reduction of humidity is to reduce the temperature to dew point up to air by the evaporator of refrigeration system, makes the water analysis being more than
Go out, to reduce the humidity of air, the humidity of Minitype manual climatic chamber is minimum can be down to 20%RH.Electrode humidifier passes through
One SCR control changes the duty ratio of voltage to adjust humidification amount；Wind speed regulation room is furnished with the frequency conversion of a variable wind speed
The indoor wind speed of weather can be adjusted in axial flow blower.The frequency conversion axial flow fan maximum quantity of wind is 44062m3/ h, by one
The different air quantity output of a Frequency Converter Control, the range that wind speed is adjusted is in 0-11m/s；It is set in dummy room there are one mounting platform,
Human body artificial limb or test board that test uses can be installed above, can also place other instruments for test；Minitype manual
Climatic chamber mainly controls all hardware by one piece of industrial master board, coordinates temperature, humidity, wind speed, pressure, liquid level sensor, on
Position machine software can be automatically adjusted to required temperature, humidity, wind speed by built-in pid algorithm.
Structure of the invention reasonable design, the addition of the frequency conversion axial flow fan of especially variable wind speed, makes the environment of simulation more
Add and tallies with the actual situation.It is truer, accurate that the thermal resistance come, dampness result are measured under this artificial climate environment.
