A centrifugal chiller is among the options to consider for an HVAC project that aims to cool the building, plant, or even a machine. The centrifugal chillers can be defined as a high-performance HVAC system that depends on compressors to move the heat-absorbing refrigerant around the coil. It uses the vapor compression cycle to chill the water. It throws off the heat collected from the chilled water plus the heat from the compressor to a water loop. The water loop is cooled by the cooling tower. This machine is most preferred because of these least complicated components, which are easy to maintain.
The Working Principle of Centrifugal Chiller
There are four major steps in which the centrifugal chiller functions:
1. Evaporator
It is a heat-exchanger that removes the heat from entering with the child water. A shell and tube is the most common heat common configuration. The heat changes the refrigerant from liquid to gas. It is an energy-efficient process. The chilled water circulates in the tubes, and the refrigerant completely submerges the tube in the shell.
2. Compressor
The compressor works towards converting the kinetic energy into dynamic energy for the fluid flow. The refrigerant enters the pump impeller and is accelerated, flowing radially towards the exit. A frictionless centrifugal compressor uses magnetic bearing technology and a DC motor drive. The process raises the pressure of the refrigerant by converting the kinetic energy into pressure and heat.
3. Condenser
It is quite similar to the evaporator, more like a shell and a tube heat exchanger. It removes the heat from the refrigerant gas, the pressurized refrigerant condenses to the liquid, which in turn raises the temperature of the condensed water. The condenser tower then carries that heat away to the cooling water, where the excess heat is ejected from the atmosphere.
4. Expansion Device
Once the refrigerant condenses to a liquid, it passes through the device to reduce the pressure. It can be a simple orifice plate or an electronic modulating valve.
What is the Use of a Centrifugal Chiller?
Each project has it’s specific requirements. The centrifugal technology is best suited larger cooling applications, unlike the reciprocating chillers, that is apt for cooling small to medium applications. The centrifugal chiller is always considered because they have a large cooling capacity by releasing a relatively small carbon footprint. It also maintains a high efficiency level during the operations. They are used for:
1. Food Processing
The food processing industries need a specific and uniform temperature while the manufacturing process is going on. It helps in maintaining the quality of the product.
2. Metal Industry
Temperature control is essential for electroplating and electroless plating to remove the heat to bond the metals at the right temperature.
3. Pharmaceutical Industry
It creates plastic parts for injection components like molds and thermoplastic pellets. The precise temperature ensures no cracks or deformation while manufacturing the components.
4. Space Cooling
The manufacturing plants and the warehouses generate a lot of heat during the production process. In such a situation, the chiller helps in reducing the heat in the given space, reducing and cooling the environment so that the machine exhausts less and so does the workers.
Final Words…
The centrifugal chiller is one of the most integral parts of the industries. It will help you reach the cooling capacity that your business needs. One of the major advantages that makes it better than others is that it is a substantial and eco-friendly process, which has the least wastage of resources.
