The Embrapii Polo / UFSC Unit and Whirlpool worked together to experimentally investigate the effect of non-condensable gases on the thermo-acoustic performance of domestic refrigerators. The presence of non-condensable gases in refrigeration systems is undesirable and is mainly due to the evacuation process during manufacture. These gases increase the energy consumption and the noise of the refrigerators, thus generating unnecessary expenses with technical assistance. In this project an unprecedented technique was developed to detect the presence of these gases still in the production line. Through this tool, Whirlpool will greatly reduce your technical support expenses and increase customer satisfaction.

According to Marcelo Salomé, Engineering Manager of Whirlpool S.A., the project generated an unprecedented method that identifies and quantifies the contamination still in the production line, significantly reducing the possibility of products without conformity reaching the consumer's home. In Brazil alone, this method can reduce by up to 26% field service for failure modes related to non-condensable gases. This translates into reduced orders for work orders, increased product quality and, above all, increased consumer satisfaction.

ABOUT THE EMBRAPII POLO/UFSC UNIT

Since 2014, Polo has been operating as Embrapii Unit, focusing on energy efficiency and environmental impact, acoustic comfort, component reliability, evaluation and certification. Embrapii was created to encourage innovation in the industry and the costs of the projects are shared. Embrapii invests 1/3 and 2/3 is divided between the company and the research institution.
