Variable frequency chiller units, screw type variable frequency chiller units, explosion-proof screw type variable frequency chiller units have usage cases, and can be customized according to user requirements.
Features of variable frequency chillers, screw type variable frequency chillers, and explosion-proof screw type variable frequency chillers:
1. Variable frequency energy-saving
The energy-saving of frequency converters is mainly reflected in the application of fans and water pumps. In order to ensure the reliability of production, various production machinery has a certain margin when designing and using power drives. When the motor cannot operate at full load, in addition to meeting the power drive requirements, the excess torque increases the consumption of active power, resulting in waste of electrical energy. The traditional speed regulation method for equipment such as fans and pumps is to adjust the air and water supply by adjusting the opening of the inlet or outlet baffle and valve. Its input power is large, and a large amount of energy is consumed in the interception process of the baffle and valve. When using variable frequency speed regulation, if the flow rate needs to be reduced, the requirement can be met by reducing the speed of the pump or fan.
2. Power factor compensation energy-saving
Reactive power not only increases line loss and equipment heating, but more importantly, the decrease in power factor leads to a decrease in active power in the power grid. A large amount of reactive energy is consumed in the line, resulting in low equipment efficiency and serious waste. After using a variable frequency speed regulation device, due to the internal filtering capacitor of the frequency converter, reactive power loss is reduced and the active power of the power grid is increased.
3. Soft start energy-saving
The hard start of the motor causes serious impact on the power grid, and it also requires excessive capacity of the power grid. The large current and vibration generated during startup cause great damage to the baffle and valves, which is extremely detrimental to the service life of equipment and pipelines. After using the frequency conversion energy-saving device, the soft start function of the frequency converter will make the starting current start from zero, and the larger value will not exceed the rated current, reducing the impact on the power grid and the requirements for power supply capacity, and extending the service life of equipment and valves. Saves equipment maintenance costs.
