Which of the following can increase the efficiency of a heat exchanger in closed loop systems?

E. Pipe-within-a-pipe design: hot water in inner pipe and glycol in outer pipe
F. Counter-flow path
G. Both A and B
H. Neither A nor B

Explanation

Answer: C - Both a pipe-within-a-pipe design and a built-in counter-flow path can increase the efficiency of a heat exchanger in closed loop systems. This is important because the heat exchanger has a significant impact on the efficiency overall of the closed loop system. Any gains in efficiency in this component will increase the efficiency of the system overall.
