Existing GDJS has following defective:
1. the single open-door design is adopted in existing chamber more, operating room's narrow space, and the test specimen accommodation space is not enough, when if the test specimen volume is bigger than normal, it is less test specimen and operating room's inwall distance to occur, and cold air or hot air circulate are not smooth, affect test effect;
2. air circulation in the single air blast band moving chamber are adopted in existing chamber more, and a connectivity part only is set between operating room and the blast channel, the air that blast channel discharges and the air that inwardly sucks form easily herein and liquidate, a little less than the air circulation ability, when alternating hot and cold, cold air or hot-air can't in time enter circulation, so that test effect is affected;
3. existing chamber chamber door adopts the individual layer rubber seal more, and after a period of time was used in chamber, because rubber deforms, cold air or hot-air leaked easily, also can cause certain influence to test effect.
Summary of the invention:
The purpose of this utility model provides a kind of GDJS.It when increasing the chamber accommodation space, the air circulation system in the improved test case, simple in structure, experiment effect is good.
The technical scheme of a kind of GDJS described in the utility model is achieved in that
A kind of GDJS is characterized in that:
It comprises housing, and the front of housing is provided with the opposite opened chamber door, and chamber door adopts the silicon bi-layer rubber seal, is provided with operating room, blast channel, condenser and compressor in the housing;

Described wind recirculation assembly comprises:
Two centrifugal blowers spaced apart are provided with the first dividing plate between the centrifugal blower, each air blast opposite side is provided with several second partitions;
Form flaring air outlet between the first dividing plate and the adjacent second partition, between second partition and the blast channel madial wall, form air inlet between each second partition of centrifugal blower the same side.
A kind of GDJS described in the utility model compared with prior art has following advantage:
1. the opposite opened chamber door is adopted in this chamber, and the space of operating room is larger in the chamber, can the larger trial target of receiving volume, trial target and operating room's inwall can be reserved larger space, can not stop that the work indoor air circulation flows, chamber is widely used, and test effect is good;
2. this chamber comprises at least one group of wind recirculation assembly, each wind recirculation assembly comprises two air blasts, first baffle plate and several second baffles, form respectively independently air outlet and independently air inlet between each baffle plate, because the division of baffle plate, air cycle efficiency in the chamber operating room is higher, has further improved the test effect of chamber;
3. rear end of the common composition of the first dividing plate and second partition is little, the tubaeform air outlet that front end is large, between each second partition, form opening direction between second partition and the blast channel interior sidewall surface away from two air inlets of air outlet, under the effect of air blast, blast channel is interior in the larger blast of air outlet place formation, and be discharged in the operating room by larger air outlet front end, each air inlet is owing to the negative pressure of blast channel inside is pumped into the air in the operating room in the blast channel, form the air circulation loop of a closure, larger blast has further promoted air cycle efficiency;
4. this chamber chamber door adopts double-deck silica gel sealing, and long-term use is not yielding, has better sealing effectiveness;
5. a dismountable commodity shelf is set in the operating room, and when the trial target volume was larger, detachable lower commodity shelf further promoted the usage space of operating room; When a plurality of trial targets are tested simultaneously, can use commodity shelf to separate, improve the utilization rate of chamber.
Be provided with a heat-insulation layer between the space that operating room described above and blast channel form and the housing.
