Description

The data presented here describes the behavior and characteristics of a closed chamber thermal system, with the technical capabilities needed in applications such as incubation, cell culture, refrigeration, dehydration or dry air sterilization. The dataset was collected from a low cost designed apparatus, approaching real world applications by including ambient air infiltrations, pressure and heating losses in a plastic container. This data article includes furthermore plain text data from temperature and electrical current sensors, an image that illustrates the control model, schematics of electronic circuitry needed and a 3D representation of the actual device in PDF format.

Steps to reproduce

The technique implemented is based on the digital data acquisition system, where the physical signal is acquired, converted to an electrical signal, filtered; the analog to digital conversion is carried out, and converted to text files. Three actuators were installed, which are necessary to cover the temperature ranges. This prevents an excessive use of energy, as follows: • Actuator (Ra) electrical heating element, connected at 220 VAC, that covers the temperature range from 60 ° C to 270 ° C. • Actuator (Rb) electrical heating element connected at 12 VDC, that covers the temperature range from 25 ° C to 60 ° C. • Actuator (Rc) Peltier module, connected at 12 VDC, that covers the temperature range from 25 ° C to -10 ° C.
