Question

__________ uses an intermediate fluid or solid store to hold heat.

(a) Shell and tube Heat exchanger

(b) Plate heat exchanger

(c) Double tube heat exchanger

(d) Adiabatic wheel heat exchanger

I have been asked this question in class test.

The above asked question is from Heat Transfer Applications topic in division Heat Transfer Applications of Food Processing Unit Operations

Answer 1

Correct choice is (d) Adiabatic wheel heat exchanger

To explain I would say: Adiabatic wheel heat exchangercontains a wheel and uses an intermediate fluid to hold heatand then the heat is transferred to the other side of the heat exchanger. It is used in transfer of heat between gases efficiently which is not easily possible in other heat exchanger.
