Stabilizing the Temperature and Humidity of Testing Samples in the Stability Room-Beit Jala Pharmaceutical

Abstract

Beit Jala Pharmaceutical Company saves samples of all drugs that the company produces for observation and to check its industrial quality. These samples must be saved at a stability room with specific conditions (temperature and humidity) to prevent samples spoilage. This project discusses improving controlling process inside stability rooms using programmable logic controller (PLC). PLC will have the ability to make the suitable decision to ensure temperature and humidity not being changed comparing with the reference values. This mechanism will operate by run the suitable unit of central air conditioning and cooling system inside the stability room, on the other hand, this project will also provide monitoring for the system using human machine interface (HMI) that link between the stability room observer and the system, and these data will be displayed on the HMI by a function graph showing temperature and humidity over the time intervals, also it will show temperature and humidity in ten different points inside the stability room according to the good allocation of sensors. This process will guarantee the optimized distribution of temperature and humidity all over the stability roomه
