ABSRACT - [ Total Page(s): 1 ]ABSTRACTThis paper describes the quick and precise control method for domestic refrigerator. The propose controller is based on the fuzzy logic and neutral network designed maintaining the constant inner temperature (of the refrigerator and improving the refrigerator efficiency. The fuzzy logic controller is used to maintain the inner temperature inspite of the environment variation such as outer temperature change of the volume change of the stored food to the refrigerator a neutral network is ...

CHAPTER ONE - [ Total Page(s): 2 ]As a result, we are not limited to the engagement of fruits vegetables and other product growth locally at any given time of the year, but we can have food product from the distance lands an4 other part of the country. Economic Growth: refrigeration has helped the economy of many areas by providing a means preserving their product enrooted to remote area for consumers.Hospital: Refrigerators are used in the hospitals for the preservation of bone, blood tissue and some drugs that are to be kept u ...

CHAPTER TWO - [ Total Page(s): 2 ]CHAPTER TWO2.1 LITERATURE REVIEWRefrigeration is the branch of engineering that is concern with the producing and maintaining temperature below that of the surrounding atmosphere .this implies the development of temperature differential rather than the establishment of a given temperature level. The act was known to the ancient Egyptians and the people of Indian, who use evaporation to cool liquid in porous earthen jar exposed to dry night air, and to the early Chinese, Greeks and Romans w ...

CHAPTER THREE - [ Total Page(s): 3 ]CHAPTER THREEDESIGN CALCULATIONS FOR REFRIGERATION SYSTEMHaving described the component parts of the refrigerator in thes necessary to design the system according to the requirement of the project.The system consists of the following component parts: Compressor Condenser Capillary tube Evaporator Piping (discharge and suction line). Insulation cabinel body3.1 REFRIGERANT SELECTIONThe choice of a refrigerant must be made and the proper refrige ... Continue reading---
CHAPTER FOUR - [ Total Page(s): 6 ]4.3 EVAPORATORThe evaporator is that part of refrigerating system where heat is removed from the product to be cooled. It is also called cooling coil.As the refrigerant enters the passage of the evaporator it absorbs heat from the product it begins to boil and vaporizes. In this process, the evaporatoraccomplishes the purpose of the system refrigeration William, (2005).There are two (2) classification of evaporator1. Base on operating conditioni. Flooded type evaporatorii. ... Continue reading---
CHAPTER FIVE - [ Total Page(s): 1 ]CHAPTER FIVECONCLUSION AND RECOMMENDATION5.1 CONCLUSIONRefrigeration is the science of producing and maintaining a temperature below that of the surrounding atmosphere i.e it is an act of removing heat from a substance to be cooled.This project work was a direct integration of both the theoretical acknowledge and practical skills required in the course of study, and has the acquainted the relevance of engineering science to technological growth and development.The project was based on the ...
