Types of chillers and their working principles
In industry, coolers are divided into air-cooled water coolers and water-cooled water coolers In terms of temperature control, coolers are divided into low-temperature water coolers and room temperature water coolers. The temperature at room temperature is generally controlled between 0 degrees and 35 degrees The temperature control of low-temperature machines is generally between minus 0-45 degrees Celsius. When the cold water mechanical cooling circulation system is used, the liquid refrigerant in the evaporator absorbs heat from the water and begins to evaporate. There is a certain temperature difference between the final refrigerant and water. The liquid refrigerant is also completely evaporated into a gaseous state and is sucked in and compressed by the compressor. Gas refrigerant releases heat through the condenser and condenses into liquid. After throttling through the thermal expansion valve, the liquid refrigerant becomes low-temperature and low-pressure refrigerant and enters the evaporator. Complete the process of frozen reincarnation.
Chillers may not be commonly seen in daily life, but they are a type of equipment commonly used for testing and production. It is a water-cooled device. A water cooler is a cooling water device that can provide constant temperature, constant current, and constant pressure. Chillers are divided into two types: air-cooled chillers and water-cooled chillers. Water coolers are divided into low-temperature water coolers and room temperature water coolers, with room temperature controlled within the range of 0-35 degrees. The temperature control of low-temperature machines is generally between minus 0-100 degrees Celsius. The working principle of a chiller is to first inject water into the machine's water tank, cool the water through the cooling system of the water cooler, and then send the low-temperature cooling water to the equipment ordered by the water pump; After removing cold water from hot water, the temperature rises and flows back to the water tank to achieve cooling effect.
The liquid refrigerant in the evaporator absorbs heat from the water and begins to evaporate in the refrigerant circulation system of the water cooler. The temperature difference between the final refrigerant and water is formed. The liquid refrigerant also completely evaporates and turns into a gaseous state. Liquid refrigerant is sucked in and compressed by the compressor. Gaseous refrigerant absorbs heat through a condenser and condenses into liquid. After the expansion valve is throttled, it becomes a low-temperature and low-pressure refrigerant, which enters the evaporator to complete the refrigerant recovery process. When the molded products of the chiller are different due to the type of raw materials, the size and shape of the molded products, and the required mold locking force, please adjust according to the actual minimum mold locking force. Clearly saving energy consumption and extending the service life of the machine. Attention must be paid to operational safety when using industrial water coolers. At the beginning of each operation, check the reliability of the machine's safety devices, safety top rods, and safety doors. During machine operation, be sure not to insert your hands into the clamping mechanism. When picking up the goods, ensure the safety of personnel and the absence of foreign objects inside the mold, and be sure to open and close the safety door. In addition, during operation, hands should not touch between the nozzle and the mold gate. When repairing the mold, please turn off the oil pump motor.
