The invention discloses a circulating cooling water system which comprises a cooling water tower, a refrigerating unit, a three-way valve and a heat exchanger. A water outlet of the cooling water tower, a condenser water inlet of the refrigerating unit and a water inlet of the heat exchanger are connected together through the three-way valve. An evaporator water outlet and an evaporator water inlet of the refrigerating unit are connected with the water inlet and a water outlet of the heat exchanger respectively. Working in the two modes can be achieved by controlling the communication relation of the three-way valve. According to different external environmental conditions, the different working modes can be selected to operate the system, so that the energy consumption is lowered, the refrigerating unit is switched off and only the cooling water tower is switched on particularly on the condition that the external environment temperature is low, the electricity consumption cost can be remarkably lowered, and the effect of energy conservation is achieved.
