Positive pressure explosion-proof cabinet with explosion-proof air conditioning
Thread Content
The site is a Zone 2 area with explosion hazards; the previous analysis system was integrated within a positive-pressure explosion-proof cabinet. High ambient temperatures in summer can affect the performance of the analysis system, hence cooling facilities are necessary. We plan to use vortex refrigeration, but previous attempts with similar applications showed that its performance was not good; therefore, this time we are considering using explosion-proof air conditioners. Has anyone encountered this situation? I always feel that the principle of positive pressure explosion protection might be affected by the operation of air conditioners. Has anyone encountered similar applications? Are there any other good suggestions?
We have already used explosion-proof air conditioners of domestic manufacture; they are probably quite expensive
