A CHILLER IS A WATER-COOLING DEVICE DESIGNED TO PROVIDE CONSTANT TEMPERATURE, CONSTANT FLOW, AND CONSTANT PRESSURE. THE PRINCIPLE OF THE CHILLER INVOLVES INJECTING A SPECIFIC AMOUNT OF WATER INTO THE WATER TANK INSIDE THE MACHINE. THIS WATER IS THEN COOLED THROUGH THE REFRIGERATION SYSTEM OF THE CHILLER. SUBSEQUENTLY, THE WATER PUMP INSIDE THE MACHINE INJECTS LOW-TEMPERATURE CHILLED WATER INTO THE MACHINE. THE CHILLED WATER EFFECTIVELY REMOVES THE HEAT GENERATED INSIDE THE MACHINE, AND THE RESULTING HIGH-TEMPERATURE HOT WATER IS RETURNED TO THE WATER TANK FOR FURTHER COOLING. THIS CIRCULATING EXCHANGE COOLING PROCESS ACHIEVES THE FUNCTION OF EQUIPMENT COOLING.
