Frequently Asked Questions (FAQ)
What are the advantages of the screw compressor used in this chiller?
The chiller features an efficient semi-hermetic screw compressor that ensures smooth running and low noise. It utilizes high-quality bearings with a lifespan of at least 40,000 hours, suction cooling for low-temperature motor operation, and a built-in oil separator to keep the overall unit size compact.
How does the energy regulation system help save power?
The system supports stepless energy regulation from 0% to 100% (or step-wise control like 0-33-66-100% and 0-25-50-75-100% depending on the model). This allows the compressor to adjust its output precisely matching the cooling load requirements, resulting in maximum power savings.
What types of refrigerants can be used with these screw chillers?
The LS-WSCS screw chiller series is highly versatile and is suitable for use with R22, R134a, R407C, and R404A refrigerants.
What control and automation features are integrated?
The units are equipped with a computer LCD touch screen controller providing automated procedures for power control, energy regulation, stop control, fault diagnosis, and operation statistics. They can also connect to building control systems or be operated remotely, allowing for complete automation without requiring specialized on-site personnel.
What safety protections are built into the unit?
Comprehensive security features include compressor motor overheating protection, overload protection, high and low pressure protection, frost protection, power reverse phase/phase protection, exhaust over-temperature protection, and flow switches.
What is the difference between the Single head (WSCS) and Double headed (WSCD) models?
Single head models (WSCS) utilize a single compressor configuration for standard load requirements, whereas Double headed models (WSCD) feature dual compressors, providing larger cooling capacities (up to 830 kw) and better partial-load efficiency with built-in redundancy.
