Abstract
The utility model discloses a low-noise artificial environment laboratory which comprises a primary static pressure box, an air quantity regulating valve, a secondary static pressure box and a micropore plate. An air outlet of an air conditioner is connected with the primary static pressure box, a horizontal outlet of the primary static pressure box is connected with a hung ceiling air pipe, and air flow entering the air pipe is blown to the top of the secondary static pressure box through the air quantity regulating valve and is sent to a required working region of the laboratory through the micropore plate positioned above a hung ceiling. The low-noise artificial environment laboratory has the advantage that noises can be lowered from 65-70dB originally to 40-50dB.
Description
Technical field
The utility model belongs to the resource and environment field in the science and technology class, accurate environment control, HVAC and control technology field, be specifically related to take central air-conditioning air-conditioning box or constant-temperature constant-humidity air-conditioner as Cooling and Heat Source, adopt the furred ceiling air-supply, the low noise system integration method of air quantity independent design.
Background technology
The low noise laboratory is in modern times research and development fields, require more and more higher, especially the fields such as chemical industry, electronics, familyization, weaving, medicine, printing, military project, national defence are used more and more extensive, the work noise decibel value in low noise laboratory generally can reach 40-50dB, and this is a thorny difficult problem in the central air-conditioning industry; So in artificial research and development lab construction environment, become a kind of active demand in market!
At present, we find on market, it is all to take the mode of iron duct to carry out that most laboratory with constant temperature and constant humidity ventilates, in order to reduce noise, take to paste the mode of silencing cotton on iron duct, can satisfy so general experiment needs, but can not bring comfortable working environment for the user in the artificial environment laboratory.If it is very high that the noise objective in laboratory requires, among the laboratory of some high-end customers, R﹠D building for example, the place of these scientific research institutions all can be used the laboratory in 1 year 365 days usually, under such situation, the staff understands endurable strong noise laboratory, because this is very disadvantageous to health.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of low noise artificial environment laboratory will be provided, and solves user's noise source interference situation.
In order to solve above technical problem, the utility model provides a kind of low noise artificial environment laboratory, comprise one-level plenum chamber, volume damper, secondary plenum chamber and microwell plate, the air outlet of air conditioner connects the one-level plenum chamber, the one-level plenum chamber laterally exports and connects a furred ceiling airduct, the air-flow that enters airduct is regulated the top that blows to the secondary plenum chamber through volume damper, then the microwell plate on furred ceiling is sent into required workspace, laboratory.
Mode by the one-level plenum chamber is as the one-level noise reduction, when air current composition is through airduct afterwards, adopt adjustable air port, in second noise reduction space, a larger secondary plenum chamber is arranged, after the secondary plenum chamber carries out the gas current stabilization, send into required workspace, laboratory through the mode of microwell plate air-supply; By such tertiary treatment, unit original air outlet noise in laboratory is 75dB, can be down at 40-50dB, can satisfy the low noise laboratory requirement fully.
The beneficial effects of the utility model are, noise can be reduced to 40-50dB from original 65-70dB, in low noise automatic control environmental area, demonstrate fully high reliability as the high accuracy experiment chamber, scientific research place among modern development in science and technology, environment protection health, the theory that people-oriented, have very strong practicality.
Description of drawings
Fig. 1 is schematic diagram of the present utility model;
The number in the figure explanation
1-one-level plenum chamber; The 2-volume damper;
3-secondary plenum chamber; The 4-microwell plate.
The specific embodiment
See also shown in accompanying drawing, the utility model will be further described.
In the embodiment shown in fig. 1, before the air-out of unit is entering the laboratory, must carry out one-level through one-level plenum chamber 1 and eliminate the noise and process, go out after shift of wind changes, enter laboratory furred ceiling airduct; After entering airduct through the air-flow of eliminating the noise, then regulate through volume damper 2, air-out direction is changed, direction maximum angle as far as possible blows to the top of secondary plenum chamber; Air-flow blows to the top of secondary plenum chamber, can carry out air-flow absorption, carries out air-flow along the secondary plenum chamber and unfolds, and air-flow changes through dynamic pressure simultaneously, transfers potential energy to, and air-flow is fully integrated and even at the secondary plenum chamber; After airflow uniform distribution through the secondary plenum chamber, steady air current is balanced, on average send into again the microwell plate 4 on furred ceiling, after such integration, noise reduces greatly, and the transformation that air-flow has been completed blast is very large, through the processing of this four processes, noise can be reduced to 40-50dB from original 65-70dB, is very quiet wind pushing form.
