INTRODUCTION
In this project we are designing a mechanical structure which is a deep fridge used in different bakery or ice cream parlour for cooling purposes. The multipurpose feature of this project is that we are using the cooling of deep fridge for cooling of goods as well we are using the same cooling for cooling of room. The other function of this mechanism is that we also using the heat of the deep fridge and converting the same into the energy with the help of thermostat. This thermostat will convert the heat of the fridge into volt and this energy is then preserved into a battery. Now the energy we stored in the battery can be used for any purpose.
BASIC FEATURES
1. Multi Purpose use of one fridge.
2. Using the same cooling for both purposes.
3. Heat is also transferring for useful purpose.
WORKING
First we designed a deep fridge then we connect a ducting to it by the help of exhaust fans we transfer the cooling from the deep fridge to the room and at the same time we are also transferring the heat of the fridge to the thermostat and with the help of this sensor we are converting the energy and saving the same in the connected battery. We are also using a circuit to transfer the cool air from the deep fridge time to time so that to maintain the temperature as desired.
