Design of Medicine Refrigeration for Rural and Flood Affected Areas- Fast Chilling Solar Based Refrigerator with Dual Mode Battery Charging to Preserve Antitoxin for Treatment
P. Vijaya Kumari
Abstract: For the last few centuries, fossil fuel has been considered and utilized as the main source of energy. However; the negative impacts of burning fossil fuel on the environment have forced the energy research continuity to seriously consider renewable sources of energy. Solar energy, in particular, has been the main focus in this regard because it is a source of clean energy and naturally available. Solar energy applications include solar photovoltaic and solar thermal. Solar thermal systems are used to power absorption refrigeration and air-conditioning systems. In Today?s world global warming is being increasing year by year. There are many reasons like pollution, deforestation, water contamination, etc...In coming years the major problem before us is depletion of ozone layer which is caused by the release of CFC?s. Some of the equipment which cause this effect are refrigerators and A/C?s. Here I am designing a mini solar based refrigerator for preserving injections, vaccines & Medicines to the remote areas where power supply is not possible which is cheaper as well as eco-friendly. Here I am using Micro controller (AT89S52) allows dynamic and faster control. Liquid crystal display (LCD) makes the system user-friendly. In this project Iam using solar panels for charging a Lead Acid Battery (12V, 1.2 Amp hrs), a pelteir thermoelectric device when connected to battery generates cool effect and hot effects depending on the mode required by the user. Since I am using this fridge for only cool mode, a peltier thermoelectric device is connected to the battery to generate cooling effect. I need to display the voltage for that I am using ADC0808 which is given to the controller. For this ADC Iam giving a clock pulses through 555 timer to perform its operation. This project uses regulated 5V; 500mA power supply. A 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac output of secondary of 230/12V step down transformer.
