Description
[technical field]
Environment test device technical field is the utility model is related to, specifically a kind of high/low temperature cyclic damp heat test
Case.
[background technology]
At present, the conventional humidification method of existing Temperature and Humidity Control has shallow-slot type to humidify and boiler humidifies, both sides
Formula respectively has advantage and disadvantage.Wherein, conventional boiler formula humidifier is made up of storage tank and immersion heater, when equipment works, heating
Device heats to boiler reclaimed water, and caused steam mixes by conduit with inner loop air, is uniformly scattered onto in air, is
System accurately adjusts heater working condition according to humidity requirement and produces appropriate steam.Its advantage is：1. quantity of steam is big, set to large-scale
It is standby very suitable；2. steam continues.Its shortcoming is：1. water, which is boiled, needs water larger；2. have one from cold conditions to steam is produced
The individual lag period, after humidity reaches, an overshoot value is had again；3. boiling can produce incrustation scale for a long time；4. need larger humidification
Device；5. after stopping humidification, may proceed to produce a part of steam and come out, experiment is had an impact.
And shallow-slot type humidification is similar with conventional boiler humidification, but it is that heater is placed in an open space, one
As inlet scoop position in case, when inner air sucks inlet scoop, it will inhale vapor caused by shallow slot by shallow slot top
Enter up.Its advantage is：1. being responded to humid control in time, overshoot is smaller；2. need not seethe with excitement could produce steam；It is 3. less
Boiling can produce less incrustation scale；4. repair and maintenance is convenient.Its shortcoming is：1. a large amount of steam can not be produced；2. interior case reclaimed water
Water can cause low humidity point relatively more unmanageable in groove；3. after stopping humidification, it may proceed to produce a part of steam and come out, to experiment
Have an impact.
Summary：Above two control mode respectively has advantage and disadvantage, can be produced when specific humiture alternation curve is run
Raw variety of problems.Now by taking popular standard PV1200 as an example, when being tested, shallow slot humidification method is when temperature is relatively low, definitely
When water capacity is little such as the PV1200 first steps front half section can normal regulating, but with the rising of temperature and humidity, need
The humidification amount wanted is often that shallow slot humidification can not meet, Humidity Detection value can be caused to be less than humidity set point, produce hysteresis simultaneously
There is larger overshoot when can cause to control constant.And if humidified using boiler, although Cheng great Jia moisture will after can meeting
Ask, but because curve has subzero state of temperature (the 3rd the 4th step), this period, boiler will cool down, it is cold when terminating
When jelly state starts humidification, the hysteresis quality of conventional boiler humidification just embodies clearly, and it needs a longer time to make
Boiling water, conventional humid control can be so caused to produce a larger overshoot (overshoot).
