Abstract
A water circulation system associated with a refrigerant cycle that includes an intermediate heat exchanger having a triple-pipe shape in which three independent flow passages are formed by three pipes having a concentric axis and different diameters. Accordingly, three fluids flowing through the three independent flow passages can exchange heat with each other at the same time through the intermediate heat exchanger and heat exchange capacity of the intermediate heat exchanger can selectively be varied.
