PURPOSE: A water cooling system supplies cool water always by maintaining water between a water cooler and a water provider always cool. CONSTITUTION: The water cooling system comprises a three way valve(52), an auxiliary hose(61), a water pump(49), and a thermostat switch(48). The three way valve(52) mounted on a hose(60) at a water provider(50) side alters the passage of water. The auxiliary hose(61) connected to the three way valve(52) is a path for returning water in the hose(60) to a water cooler(47). The water pump(49) prompts the flow of the water in the auxiliary hose(61). The thermostat switch(48) circulates the water in the hose(60) to the water cooler(47) through the auxiliary hose(61) by actuating the water pump(49) if the temperature of the water in the hose(60) is higher than a predetermined temperature.
