The thickness of return air orifice plate 8 is stated for 1~1.5mm, the percent opening of return air orifice plate 8 is 20~25%, the aperture of the return air through hole is 3
~5mm, distance of the return air orifice plate 8 apart from the top of test environment cabin 1 is 1000~1200mm, the return air orifice plate 8
It is 1000~1200mm with the distance between orifice plate 7 of blowing.The height of the first paragraph return air channel D is 1000~1200mm,
The first paragraph return air channel D is located at middle position at the top of the test interval A.Compact conformation of the present invention, greatly reduces
Space simultaneously reduces construction investment.
The air outlet 2 is interval with 2~3, and the distance at the top of 2 distance test environmental chamber of air outlet 1 is 1300
~1400mm, the air outlet 2 uses the fin in air grille, the air outlet 2 to use right angle fin；The return air inlet 3
2~3 are interval with, the distance at the top of 3 distance test environmental chamber of return air inlet 1 is 250~350mm, the return air inlet 3
Using air grille, the fin in the return air inlet 3 also uses right angle fin；The arrangement of the air outlet 2 and the return air inlet 3
Direction is vertical.The air outlet 2, return air inlet 3 are using the design method of air grille and right angle fin, the air grille
Effect with reduction air current composition flow velocity and temperature, prevents from entering E and the test between the air-treatment unit installing zone
Big ups and downs occur for the flow velocity of interval A air current compositions, humiture, it is ensured that air current composition is between the air-treatment unit installing zone
Uniform and stable distribution in the E and test interval A.
The maintenance door 6 for facilitating personnel's turnover to safeguard is offered on the partition wall 5, the dimensions of the maintenance door 6 is
(800~1000) mm × 2000mm, i.e. maintenance door 6 800~1000mm of width, height 2000mm.In addition in the test environment
Equipment inlet/outlet 9 is offered on the exterior wall of cabin 1, the maintenance door 6 and the equipment inlet/outlet 9 are positioned opposite.
The peripheral protective of test environment cabin 1 is formed by the thick double-side color-steel polyurethane storehouse plate composite assemblies of 100mm, the test
The internal insulation of environmental chamber 1 is gone along with sb. to guard him to be formed by the thick double-side color-steel polyurethane storehouse plate composite assemblies of 75mm.The poly- ammonia of double-side color-steel
Ester storehouse plate both sides plate face is that, with polyurethane sandwich layer between color steel layer, color steel layer, the heat preservation of board isolation performance is strong, it is easy to process
And it is assembled.
