Unveiling the Source of Shenzhen's ''Freezing Power''
Yes — it's snowing in Shenzhen! In this city that rarely sees snow, a -6°C Winter Wonderland has come to life — the Huafa Ice & Snow World in Qianhai, the world's largest indoor ski resort.
Let's step inside this 100,000㎡ snow paradise, and explore how SINEE empowers its heart with innovative drive and control solutions, delivering reliable and efficient refrigeration power to sustain this icy dream.
A Frozen Connection – Tailor-Made from Real Needs
For large indoor ski resorts, the stability and reliability of the cooling system directly determine the overall operation quality.
The SINEE engineering team conducted in-depth research and developed a customized solution — optimizing system performance from multiple dimensions, including efficiency, cost-effectiveness, and long-term reliability.
This precise matching of cooling demand and intelligent energy control helped SINEE stand out with its strong technical capability.
Every Flake Counts – Smart Control, Lower Costs
Energy consumption is one of the major challenges for ski resorts, as refrigeration systems take up a significant portion of total power use.
Drawing on years of experience in cooling equipment applications, SINEE's intelligent control algorithm maintains a constant system pressure through PID regulation, dynamically adjusting motor speed in real time to achieve stepless control.
This ensures stable operation and substantial energy savings, helping the ski resort dramatically reduce operating costs.
The Core of ''Freezing Power'' – Key Advantages of SINEE's Solution
Ultra-High-Speed Drive Capability
Supports vector control up to 0–2000Hz and VVF control up to 0–3000Hz, with torque accuracy of ±5% (SVC) / ±3% (FVC), meeting the demands of high-performance drive applications.
Intelligent Control Technology
Features adaptive carrier frequency adjustment (2–16kHz), advanced motor self-learning algorithms (static/dynamic parameter identification), and compatibility with multiple motor types — including permanent magnet, induction, reluctance, and asynchronous motors — ensuring exceptional adaptability.
Grid Adaptability
Dual-mode voltage ride-through (LVRT/HVRT) and built-in C3/C2 EMC filters ensure stable operation under power grid fluctuations.
High-Reliability Design
An independent cooling air duct system combined with reinforced PCB coating extends service life. The modular I/O design supports IO, communication, and PG card expansion, along with industrial-grade isolated RS485 communication and multiple protocols (Modbus, Profibus, CANopen, EtherCAT, Profinet), ensuring flexibility for system upgrades and integration.
