The water chiller is a kind of water cooling equipment, which can provide constant temperature, constant flow and constant pressure. The principle of the chiller is to inject a certain amount of water into the internal water tank of the machine, and the water is cooled by the chiller cooling system. Then, the water pump inside the machine will inject low-temperature chilled water into the equipment that needs cooling. The cooling water takes away the heat inside the machine, and the high temperature hot water flows back to the water tank to cool again. In this way, the cooling water is circulated and exchanged, thus achieving the function of cooling equipment.
The industrial water chiller is usually used as a complete set of closed loop system, including chilled water device, condenser and circulating pump, expansion valve, non-flow closing device, internal chilled water tank and temperature control station. The inside of the water tank helps to maintain the cold water temperature and prevent the temperature from reaching the peak. The closed loop industrial water chiller circulates under constant temperature and pressure, and improves the stability and repeatability of water cooling equipment and instrument cleaner by using conditional additives or clean water. The water flow is cooled to the application angle and returned.
If the temperature difference between inlet and outlet water is large, a large external water tank should be used to store cold water. In this case, the cooling water will not go out directly from the application of the cooler, but will go deep into the outside of the water tank as a "temperature buffer sequencing behavior". The cold water tank is much larger than the internal water tank. The application of cold water from the external fuel tank and the return of hot water from the application can be traced to the external fuel tank, not the unit.
The unusual open-loop control of industrial refrigerators maintains the circulation of liquid temperature in an open tank or oil pan. The liquid comes from the storage tank, passes through the pump unit and returns to the storage tank. An adjustable thermostatic sensing make-up liquid temperature circulates the cooler to maintain the thermostatic tank.
One of the new developments of industrial water chillers is to use air cooling instead of cooling water. In this case, the condenser is not cooled by hot air refrigerant, but by cooling water using cooling tower. This development is allowed to exceed 15%, and due to the large reduction of surface water in small areas, it is allowed to reduce the energy demand of coolers, condensers and fans. In addition, with the permission of the fan, the noise level is greatly reduced.
Most industrial water chillers are used for cooling, but some simple technologies that rely on air or water include the flow of cooling coils to regulate the temperature. In the freezing process of water, it is the most commonly used coolant, although the cooling mixture (mainly containing coolant additives to enhance the heat dissipation of water) is often used.
