Abstract

Warehouses are part of the crucial infrastructure of the logistics process of any business. The type of products stored in the warehouse also determines the type of warehouse class. The object of research in the present work is a class A warehouse with a clear height of 10 up to 13 m, equipped with systems for maintaining the indoor air quality within a very specified temperature limit. An air conditioning system is proposed, consisting of roof air conditioners (Rooftop vent), that allow maintaining the microclimate in the specified limits yearly. To achieve the specific requirements, numerical modeling of air distribution in the warehouse was performed, which shows that the use of simplified, systematized methods for the technical design of air conditioners is an unreliable approach. Moreover, the analysis shows that in high warehouses, the stagnant areas that arise cannot be overcome only by rearranging the roofing machines, but also requires the use of additional impulse mixing devices.
