ABSTRACT

This work on the construction and fabrication of a mobile deep freezer revolves around the concept of refrigeration. The concept of refrigeration revolves around the reverse Carnot cycle. This is  a cycle involving isentropic expansion (at the throttling valve), isothermal expansion (at the evaporator), isentropic compression (at the compressor) and isothermal compressor ( at the condenser) Compression raises the temperatures of the refrigerant above that of its natural surrounding so that it can give up its heat in a heat exchanger to a heat sink such as air or water (condenser). Expansion lowers the refrigerant temperature below the temperature that is to be produced inside the cooling compartment.
