ABSTRACT:
A heat exchanging system includes a condenser including a heat exchanging chamber containing a heat exchanging medium therein and having an inlet end for entrance of the heat exchanging medium, and an outlet end for discharge of the heat exchanging medium; a control device; a water mist generating device having a spray pipe for spraying water into the heat exchanging chamber in a mist manner, a supply pipe for supplying water into the spray pipe, and a water valve for controlling the water supply of the supply pipe; a variable speed fan motor operated by the control device; and a sensing device having a first sensor mounted in the heat exchanging chamber, a second sensor mounted to the water mist generating device, and a third sensor mounted to the variable speed fan motor. In such a manner, the sensing device inputs the sensing values sensed by the first sensor, the second sensor, and the third sensor into the control device to be compared with the pre-determined values contained in the control device which can be used to control the operation of the water valve and the variable speed fan motor depending on the comparison results.
