CONTROLING AND MONOTORING OF SIMPLE REFRIGERATION CYCLE

Abstract

In this project a new temperature controller was designed to replace the conventional on-off temperature controller to maintain the inner temperature of a simple refrigeration cycle and reduce the power input to the cycle. Due to the effect of high demand of power on the green house emission it is important to find new ways for power production. Also, the another important issue which is unnoticed is make sure that the power produce consumed efficiently by the load. The main concentration of research in the subject is the replacement of old systems to new in order to reduce power consumption which is a topic of interest to most researcher nowadays. This is done by adjusting the power absorbed by the system to meet the demand using variable frequency drive. Both temperature controllers of the conventional system and the new controller were designed and evaluated. Results showed that the controller was found to be more consistent and effective in maintaining the inner temperature of the simple refrigeration cycle. The both results provide full graphical development which is analyzed and have been compared. The effectiveness of the controller and its ability to maintain the inner temperature of the simple refrigeration cycle with consistency moreover the conventional on-off controller. Also the controller was able to reduce the vibration and noise produced by the cycle.
