Abstract

The invention discloses a method and system (10) for heat transfer using water. In one embodiment, the system (10) includes two water softening devices (16) for reducing the hardness of the feed water, the water softening devices (16) being connected to the filtering device (14) and supplying the softened water to the filtering device. A filtering device (14) removes minerals from the water, thereby producing a quantity of filtered water and waste water. The filtering device (14) sends a quantity of filtered water to the heat exchanger (12). The heat exchanger (12) evaporates a certain amount of filtered water and produces a certain amount of mineral deposits. A certain amount of mineral deposits is sent to a filter unit (14) to remove these mineral deposits, thereby producing a certain amount of recirculation water and discharge water. Thereafter, an amount of recirculated water is sent to the heat exchanger (12) for reuse, while an amount of drained water is discharged into a waste container (24).

Description

technical field

[0001] Generally, the present invention relates to a heat exchanger utilizing water for heat transfer, and more particularly to a method and system for improving heat transfer using a reverse osmosis system combined with a water softening device. Background technique

[0002] Heat exchangers utilizing water for heat transfer are known. Two examples of such heat exchangers are boilers and cooling towers. When boilers generate steam or water evaporates from cooling towers, minerals are usually deposited and left behind. Typically, most of the minerals are brought in by water added to replace water lost through steam or evaporation. Eventually, mineral deposits can build up on heat exchanger surfaces to the point where they significantly impede heat transfer. In addition, the increasing mineral concentration will also corrode the heat exchanger, thereby further reducing the efficiency of the heat exchanger.
