Abstract

This paper presents "Redesign of the controlled environment simulation chamber for calibration of thermohygrometers of the company EMCO CIA. LTDA" The project is based on ISO 17025 standards to improve the company's chamber, focusing on its laboratory quality management system. With the redesign, the refrigeration system components increased in power, which implied a higher energy demand. The heating system now requires 2500 W in order to adequately supply the thermal needs. On the other hand, the humidification system needs a flow rate of 10 kg/h to meet the required ranges and ensure complete coverage of the entire chamber area. Elements were selected with the objective of optimizing space, increasing the size and isolating the interior from external variations. In addition, we sought to expand the range of temperature and relative humidity measurements, covering values from 10 to 50 degrees Celsius and from 20 to 90% relative humidity. Tests were carried out to achieve these standards, adjusting parameters and using Mt530 controllers with an interface compatible with mobile devices and computers. The implementation of the chamber would result in increased revenue for the company by enabling the calibration of at least 40 instruments per month, thanks to reduced stabilization time and the ability to calibrate up to 10 thermohygrometers simultaneously in the same box.
