Title: Slime separating method for heat exchanger
Inventor: WATANABE SUMIO
IPC: F28F19/01
Filed: 1994-12-12
Abstract: PURPOSE: To effectively remove slime stuck to a heat exchanger by generating ozone water having predetermined concentration irrespective of the water temperature and the atmospheric temperature to generate the ozone water. CONSTITUTION: Ozone water is previously generated before ozone treating while measuring the ozone concentration of the ozone water by an ozone concentration meter 22.
