Brochure Datacenter cooling with VZH inverter scrolls - GB

Product catalog summary

Introduction
Cooling IT equipment in data centers is increasingly challenging due to power management, energy consumption, and heat loads. Danfoss inverter scrolls offer advanced efficiency and accurate cooling to address these challenges.

Key Challenges

Power management and energy consumption are major concerns.
Cooling can account for up to 50% of a data center's energy cost.
Accurate humidity and static electricity control are essential.
Minimum start-up current is crucial for sensitive power grids, reducing downtime and increasing system lifetime.

Danfoss VZH Compressor Features

Capacity range: 13-26TR (47-94kW) in a single unit, up to 52TR in tandem.
Extended modulation capacity from 25 to 100 rps.
Operates with R410A refrigerant.
Optimized for low and high pressure ratios.

Energy Savings

The VZH inverter scroll cycles from 25 to 100 RPS, reducing energy waste.
Consumes 90% less energy in part-load operation compared to fixed-speed compressors.
Patented manifold technology increases capacity range up to 183 kW (52TR) at full speed.

Accurate Temperature and Humidity Control

Temperature control within +/- 0.3°C ensures data availability and protects components.
Maintains optimal humidity levels to prevent Electro-Static Discharge (ESD).

Reduced Applied Costs

Prequalified compressor and drive package speeds up time to market and enhances reliability.
Drive replaces soft starter device, reducing inrush current by about 70%.
Reduces investment in Uninterruptible Power Supply (UPS).

Enhanced Reliability

Modulates cooling capacity according to load, reducing frequent on-off cycles.
Prequalified drive reduces vibration issues, ensuring safe operation and prolonging unit lifetime.

Conclusion
Danfoss inverter scroll solutions provide significant energy savings, accurate control, and enhanced reliability, making them an ideal choice for data center cooling.
