A Hybrid System for Power Refrigerate & Air Conditioning System By Renewable Source of Energy

A state of the art review is presented of different technologies that are available to deliver refrigeration from solar energy. The review covers solar electric, wind mill and some new emerging technologies. In this paper, a technique is used to run the refrigerator as well as air conditioner through the use of heat generated from refrigerator simultaneously. Thus the entire process is highly efficient as it minimize losses of the whole system. The use of relay in this technique of multi energy source refrigerator is that when the required power is not provided from solar, it will trip the circuit to wind energy and if both are inadequate the power will be supplied from electricity. In this system, refrigerator will operate with two panel and the panel movement is controlled by using PLC controller through the stepper motor and rotate the panel in the direction of maximum intensity of sun .In this paper a relay driver circuit (Logic switching) is used to trip the source which are generating maximum power at normal conditions. A Z- source inverter is connected to charge controller which converts DC into flexible and flexible AC to run the refrigerator. A variety of combined or hybrid system have also been investigated. Solar refrigeration can also inexpensive it would give the electric grid much relief mostly in summer days.
