Abstract
The study deals with a new sponge ball cleaning system for a heat exchanger at an air conditioning system in industries. The new sponge ball cleaning system and the coolant-sponge separator using a centrifugal force were reported by the authors in the first symposium (ISEM 2006-Sapporo) and here, an improved separator or a compact-type one was designed and studied by a simulation experiment using the transparent scale-down model. The experimental results showed that the separation performance of the compact-type separator was better than that of the first model reported in the previous symposium, and that the pressure loss of the compact-type separator was larger than that of the first model. Furthermore, the demonstration of the new sponge ball cleaning system showed that the system was useful to clean the heating tubes.
