Avaliação de temperatura do ar em armazém utilizando controle estatístico de processo

Abstract

Warehouses are facilities maintained in strategic locations for the purpose of organizing, allocating and managing goods in order to regulate the flow between supply and demand. When it comes to grain storage, its management is essential to ensure completeness and preserve its quality, avoiding subsequent product losses. Humidity and temperature parameters, when not controlled, can encourage the proliferation of fungi, accelerating the deterioration process. In this sense, this work studied the behavior of the temperature of a typical warehouse in response to the air infiltrated inside due to the opening and closing of the forklift access door. The concepts studied in the area of Statistical Process Control were used, aiming to identify the behavior of the warehouse temperature over 30 days of typical operation. It was concluded that the behavior of the air temperature inside the warehouse showed different behavior in the different regions of the analyzed warehouse. The most affected temperature was measured at the outlet of evaporator #1, while the air temperature at the outlet of the other evaporators practically did not change significantly.
