An Insight Into The Significance Of VSD Drives For Refrigeration Units

A VSD drive is a vital component of many different types of cooling systems since it can help control the machinery by controlling the speed. A VSD (Variable Speed Drive) is useful for many different types of machines that have the feature for variable speed and helps several purposes. VSD drives are useful for a wide number of applications since many devices make use of motors that can be controlled with the help of a VSD. This drive is strategically connected between the fan motor and the switchboard to ensure it can be operated. A VSD is similar to a VFD however, there is a subtle difference.

While the VSD controls the speed of the motor by changing the input voltage for both AC and DC motors, the VFD (Variable Frequency Drive) does so by changing the voltage and frequency but can be used only with AC motors. This article goes on to provide vital information on the importance of VSD in refrigeration units.

Benefits of VSD

A large number of electrical devices use motors and are made to run at a constant speed which is not always necessary. This includes refrigeration units and HVAC systems as well. Implementing a VSD can help save money since this makes it possible to adjust the speed of the motor. There are several benefits of using VSD as listed here:

  •  Allows varying the torque in various electrical appliances like HVAC and refrigeration units like fans and air pumps.
  • Adjusting the VSD to run at half the speed will mean reducing the torque that decreases the speed and utilizing one-fourth the energy of that used at full speed.
  • The VSD controllers offer more precise speed control making it more flexible and useful for a wider range of applications.
  • It can help prevent damage to the system by changing the speed as and when necessary. It does this by delivering the precise torque and halting at the exact moment.
  • This one component can make a big difference to any system by offering better quality service, conserving more energy and also maximizing the longevity of the system in use.
  • Including a VSD in your system will reduce the amount of current being drawn and increase the life of the motor.
  • It can also help prevent spikes in current that tend to occur as a result of a circuit overload.

 A very good example of the importance of VSD in your system is evident from an HVAC system that consists of two motors. In this case, it is highly likely that you find the system performance is not to your liking. Placing a VSD can help regulate the airflow. It can do this by controlling the speed of the three-phase AC motor and save a lot of money on the energy bill in the process.

A VSD plays a vital role in extending the lifespan of a motor and also reducing the danger from voltage spikes. It helps stabilize the current flow and prevent damage in the case of a sudden power surge. A power surge has the potential to damage the motors and several other components of a system; this can be prevented. This is an essential component during commercial refrigeration repair since it can reduce the power line disturbance and also lower startup power requirements. It can also reduce the energy consumption and allow one better control over the speed and acceleration of a system. VSD works out to be highly cost-effective over a period of time.
