POLO provides technical support to the various cooling companies in the industry, providing innovative and practical solutions for the development of new products or improving existing products. This support is given either experimentally, by assembling and testing prototypes chamber or stands as a computational manner by the various simulation software that was internally developed and validated over time. In the experimental front, POLO develops benches and tests in order to meet the specific needs of manufacturers. In the computational front laboratory uses variable complexity degree of simulation packages, with minimal information extracted from the experiments. With them it is possible to simulate the system as a whole and a particular component separately. Templates can only be on a permanent basis, but also in almost static and transient. The heat exchangers can be discretized both for single and three-dimensionally.
