Abstract:
A refrigerating/air conditioning heat exchanging system comprising a condenser, and a heat exchanging medium flowing through the condenser, and the condenser comprising:an air cooling type heat exchanging chamber containing the heat exchanging medium therein, and including an inlet end for entrance of the heat exchanging medium, and an outlet end for discharge of the heat exchanging medium, a water collecting pan mounted on the bottom of the heat exchanging chamber;a control device;a water mist generating device including a spray pipe mounted on the heat exchanging chamber and provided with a plurality of pores for spraying water into the heat exchanging chamber in a mist manner, a supply pipe connected to the spray pipe for supplying water into the spray pipe, and a water valve mounted on the supply pipe and operated by the control device for controlling the water supply of the supply pipe;a variable speed fan motor mounted in front of the heat exchanging chamber and connected to the control device which controls operation of the variable speed of the variable speed fan motor; anda sensing device connected to the control device and including 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;wherein, 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.
