Chemical Product - One word from the broad category: Household - One word from the sub-category: Appliance - Chemical product: Refrigerator - Chemical engineering principles: Vapor-Compression cycle, Heat transfer - Category: Chemical Device ( Although it is not considered as a miniature device, refrigerator does not fit in any of the other categories; commodities, molecular products or micro-structured product) The chosen product is a refrigerator. The refrigerant evaporates completely to absorb the heat from the surrounding region to be refrigerated. The refrigerant will leave the evaporator and then enters the compressor to increase its pressure so that it can reach the condenser. The gaseous refrigerant is then cooled back into a liquid state where the heat is released into the surrounding. The refrigerant is ready to absorb heat through the evaporator again. Vapor-Compression cycle: More details of how the cycle works: The refrigerant, which is the working fluid in t
