| The process of cold storage chambers contributes largely to the quality and longevity of stored products. In recent years, it has been intensified the study of control strategies in order to decrease the temperature change inside the storage chamber and to reduce the electric power consumption. This study has developed a system for data acquisition and process control, in LabVIEW language, to be applied in the cooling system of a refrigerating chamber of 30m³. The use of instrumentation and the application developed fostered the development of scientific experiments, which aimed to study the dynamic behavior of the refrigeration system, compare the performance of control strategies and the heat engine, even due to the controlled temperature, or to the... |

| The authors designed the optimal air-conditioning system of the greenhouse which minimizes the water and energy by computer simulation. In this design, a heat balance model and water balance model in the green house were constructed and they were considered to be constrained conditions. Furthermore, in order to evaluate the influence of the plant on this condition, the effect of higher relative humidity levels on the growth chambers of cucumber seedlings were also investigated. Three higher relative humidity conditions, RH74.5%, 86% and 97.8%, were taken into consideration in the experiment. Consequently, it was useful to introduce the fog cooling system, thermal storage mediums, ice from the desalination process and gas absorption refrigerator with... |
