The importance of total control and perfect setting for industrial cold rooms, requiring the operator expertise, electrical and the use of specific programs for management and control equipment. Among the advantages of using these programs is the safety and agility provided in their platforms and databases. The multipressão cooling bench of thermodynamics lab UTFPR-CP was prepared for the implementation of a management system and control of cooling chambers following good refrigeration practices. The management program is used Sitrad, Full Gauge Controls. The program receives data from temperature controllers and pressure linked to thermocouples. Thermocouples are installed at specific points in the refrigerating cycle for a safe and reliable monitoring in accordance with the flowchart, need be adequately insulated to ensure acquisition of data without interference from ambient temperatures which could alter the temperature parameters. The program allows you to set alarms, temperature and pressure, thaw, among other specific functions of its programming as model and features. After checking all electrical parts and possible leaks or pressure loss in the line was performed the configuration of controllers and micro controllers countertop is important to realize the vacuum in every line, then start the load process of placing the R-404a gas as used in the specification of the compressor system, the thermal analysis of the refrigerating cycle is very important to verify the efficiency of the cycle according to the good cooling practices. The result shown in the configuration and programming bench clearly demonstrated the applicability of the methodology chosen for the development of work.
