Abstract:
The most common refrigeration appliance uses a vapor-compression refrigeration system. The system consists of a compressor, a condenser and an evaporator. This cycle is called “Vapor-Compression Refrigeration Cycle.” Refrigerant gas is compressed by a compressor and the compressed refrigerant releases heat by a condenser with constant pressure. At the evaporator, refrigerant gas is extremely expended with low temperature, thus ice will be formed gently around the evaporator coil. This research designs a new concept of ice forming detector, which can replace general NTC thermistors. CFD simulation can help approach the ideal design of the ice detecting sensor, which can be built by using a 3D printer. At the end of the research, test bench with a simple refrigeration system will be prepared and be tested using several type of ice detecting sensors to find the most ideal design of ice detecting sensor.
