Industrial chillers are equipment used to control the cooling of products, mechanisms and factory machinery. The chillers for industrial applications can be centralized, and each chiller can meet multiple needs for cooling, or be dispersed in each application or device with its own chiller. Each method has its advantages. It may also have a combination of central and decentralized chillers, especially when the cooling requirements are the same for certain applications or use points, but not all.
1. Adjust the reasonable operating load of the refrigerator equipment. Under the condition of ensuring the safe operation of the equipment, when the refrigeration host runs at 70%-80% load than when it runs at 100% load, the power consumption per unit cooling capacity is smaller. Using this method to start up should be combined with the comprehensive consideration of the operation of the water pump and cooling tower.
2. Reduce the condensation temperature. On the premise of meeting the equipment safety and production requirements, try to increase the evaporation temperature and reduce the condensation temperature. For this reason, the cooling tower has been modified to ensure the efficiency of cooling water.
3. Adopt refrigerator frequency conversion device to adjust the speed of centrifugal refrigerator compressor. After the low pressure refrigerant passes through the centrifuge, the pressure increases. The higher the speed of the centrifuge, the higher the pressure rise. In actual operation, most of the equipment is running under full load. A centrifuge with a fixed speed causes a waste of energy when the equipment is running at a small load. The frequency conversion centrifugal refrigerator can automatically adjust the compressor speed according to the change of the load, and the energy saving space is relatively large.
