PID és ON-OFF szabályozású hűtéstechnikai rendszer termikus szimulációs modellezése
Abstract In a previous research project the energy consumption of a newly developed DC inverter refrigerant, used in the commercial sector, were optimized, which included speed regulator compressor, electronic expansion valve and PID regulator. In order to achieve the test goals, an experimental test facility was built in the introduction room of a national company. The main part of the measuring system was a cooling chamber containing two identical evaporators; one is powered by the DC inverter refrigerator, and the other one is traditional refrigeration system, operated by a conventional piston compressor, mechanical expansion valve and ON-OFF control technology. Due to incomplete data supplied by the manufacturer, the PID controller of the DC refrigerator had to be optimized by setting the appropriate proportional, integrating and differential parameter values to ensure energy-efficient operation. As a continuation of the research, the aim is to develop a thermal simulation model that can be used to investigate the thermal parameters of the different regulation (ON-OFF and PID) air-conditioning system used to cool the refrigeration chambers.
