Now consider changing the evaporator to a shell & tube heat-exchanger and we have an air-cooled chiller. Heat transfer equipment may be designated by type or function it performs, such as chiller, condenser, cooler reboiler, etc. The choice of shell and tube type is determined chiefly by factors such as the need for the provision for differential movement between shell and tubes, the design pressure, the design temperature, and the fouling nature of the fluids rather than the function. Heat transfer coefficient from finned tubes to air is the major resistance governing the heat exchange between sodium and air.
