A screw chiller is an environmental chilling machine that cools its surroundings using a screw compressor. It is an essential part of the HVAC system which regulates the tempature. From data centres, labs, and manufacturing sectors, all of them need screw chillers to provide efficient cooling. It maintains the quality of the product. If you, too, want to invest in a screw chiller, but before that, want to understand the cooling solution, this post is for you.
What is a Screw Chiller?
The scew chiller is a type of chilling machine that uses a screw chiller to achieve the precise cyclic refrigeration. The high-power output, strong cooling capacity, and low noise of the machine cool the surrounding space evenly. The machine uses air or water to absorb the heat and ensure a consistent temperature. This continuous compression results in quick, quiet, and more efficient operations.
How Does the Screw Chiller Work?
The screw chiller works in just four steps:
Evaporator:
The refrigerant absorbs the heat from the chilled water, evaporating into a low-pressure gas.
Screw Compressor:
The gas enters the screw compressor, where it is converted into high-power and high-temperature gas.
Condenser:
The heated gas is now cooled when it flows into this section of the machine using either air or water. Thus, it is converted into high-pressure liquid.
Expansion Valve:
The refrigerant passes through the expansion valve, dropping the pressure and temperature before into the evaporator to continue to cycle of cooling cycle. This endless loop continues to keep the surrounding temperature chilled.
Types of Screw Chillers
There are two types of screw chillers:
Air-Cooled Screw Chillers:
The air-cooled chillers absorb the heat from the surrounding temperature, making the air cool. The integrated fans and heat exchanger coils help release the absorbed heat directly into the atmosphere. It is apt for outdoor installation and has a lower installation/ maintenance cost. These chillers are used in small and medium-sized commercial buildings, data centres, as well as manufacturing plants, as it is simple to use and easy to maintain.
Water-Cooled Screw Chillers:
The cooling mechanism uses water from the cooling tower to remove excessive heat from the refrigerant. It is more energy-efficient and provides consistent cooling performance, even in a hot environment. However, this cooling machine requires a separate cooling tower and water circulation system. Though the cost of this machine is higher, it’s a high-quality output that will lower the operational cost over time. This machine is mostly preferred in large industries like hospitals, shopping malls, and buildings.
Maintenance Tips for Screw Chillers
The proper maintenance tips are also needed for the screw chillers, ensuring the reliability and longevity of operations.
- Check the compressor and oil levels regularly
- Inspect the refrigerant leaks and maintain a proper charge.
- Monitor the control, sensors, and alarms for accurate operations
- Schedule an appointment with professionals for regular inspections.
