Modern development with the progress of industry, energy-saving emission reduction needs. Frequency conversion technology is now more and more widely used in a variety of machinery and equipment. Davosi as a refrigeration industry leader, the first to introduce frequency chiller. To meet the current trend of development of science and technology. For the community's energy-saving emission reduction to make a contribution to us.

 

Frequency conversion chiller Features:

1, frequency energy saving

   Inverter energy-saving mainly in the fan, the application of the pump. In order to ensure the reliability of production, all kinds of production machinery in the design with power drive, have left a certain margin. When the motor can not run at full load, in addition to the power drive requirements, the excess torque increases the consumption of active power, resulting in waste of electricity. Fans, pumps and other equipment The traditional speed control method is to adjust the inlet or outlet of the baffle, the valve opening to adjust the amount of air supply and water supply, the input power, and a lot of energy consumption in the baffle, the valve closure process in. When using frequency control, if the flow requirements are reduced, by reducing the pump or fan speed to meet the requirements.

2, power factor compensation for energy saving

   Reactive power not only increase the line loss and equipment heat, more important is the power factor reduction caused by reduced power grid power, a large number of reactive power consumption in the line, the use of equipment inefficient and wasteful, the use of frequency control device , Due to the role of inverter internal filter capacitor, thereby reducing the reactive power loss, increasing the active power of the grid.

3, soft start energy saving

   Motor hard start on the power grid caused a serious impact, but also on the grid capacity requirements are too high, the start of the large current and vibration on the baffle and the valve damage greatly, the equipment, pipeline life is extremely unfavorable. The use of frequency conversion device, the use of the inverter soft start function will start the current from zero, the maximum does not exceed the rated current, reducing the impact on the power grid and the power supply requirements, extending the use of equipment and valves life. Saving equipment maintenance costs.
