Does it support inverter or variable capacity control?

Aurashu integrates advanced inverter technology into its air-cooled screw chiller and heat pump systems by combining high-efficiency screw compressors, intelligent variable frequency drives (VFD), and a smart control platform. This enables the unit to continuously adjust compressor speed and cooling or heating output based on real-time load demand, ambient temperature, and system operating conditions.

Unlike conventional fixed-speed chillers that operate in simple ON/OFF cycles, Aurashu inverter-driven units modulate capacity smoothly. The compressor speed can vary across a wide range—typically from low-load operation (30% or below) up to full capacity—allowing the system to precisely match the building’s actual cooling or heating demand. This avoids frequent starts and stops, significantly reducing power consumption and mechanical wear.

Variable capacity control is further enhanced through multi-step capacity regulation and intelligent logic control. When multiple compressors or circuits are used, the system automatically stages capacity by combining inverter modulation with optimized compressor sequencing. This ensures stable supply water temperature, minimal fluctuation, and high comfort levels, even under rapidly changing load conditions.

From an energy-efficiency perspective, inverter control greatly improves part-load performance. Since most HVAC systems operate under partial load conditions for the majority of the year, Aurashu units achieve notably higher IPLV and seasonal energy efficiency ratios. By lowering compressor speed during low-load operation, electrical consumption drops dramatically, often delivering energy savings of 20–40% compared to fixed-speed units, depending on the application.

Aurashu’s variable capacity control also enhances system reliability and lifespan. Soft start and smooth speed regulation reduce inrush current, mechanical stress, and thermal shock to the compressor and electrical components. This results in lower failure rates, longer service intervals, and reduced long-term maintenance costs—key advantages for commercial, industrial, and mission-critical applications.

In heating (heat pump) mode, inverter technology plays an equally important role. The system can automatically adjust heating output in response to outdoor temperature changes, ensuring stable heating performance in both mild and cold climates. For low-ambient conditions, Aurashu applies optimized inverter control strategies to maintain heating capacity, improve defrost efficiency, and reduce energy loss during winter operation.

The inverter and variable capacity functions are fully integrated into Aurashu’s intelligent control system. The controller continuously monitors parameters such as load demand, water temperature, ambient temperature, compressor status, and system pressure. It then dynamically adjusts operating frequency, capacity output, and system logic to achieve optimal efficiency and reliability. The system also supports building management system (BMS) integration via standard communication protocols, enabling centralized monitoring and energy management.

In summary, Aurashu Screw Type Air-Cooled Chiller & Heat Pump Units not only support inverter and variable capacity control, but are specifically engineered to maximize the benefits of this technology. This makes them an ideal solution for projects that require high energy efficiency, flexible operation, precise temperature control, and long-term operational stability.
