Pertanyaan umum tentang Vivaldi dari 3G Electric.
What is the difference between Vivaldi's Inv and Full Inv models?
Vivaldi's 'Inv' designation indicates an inverter-driven compressor that modulates cooling or heating output to match the load, rather than cycling on and off. 'Full Inv' models, such as the Symphonie SX120 Full Inv, typically feature inverter technology on both the compressor and the fan motors, providing finer control over airflow and further reducing energy consumption. In practice, Full Inv units offer improved part-load efficiency and quieter operation, making them suitable for applications with highly variable thermal loads, such as conference rooms or open-plan offices.
What is the maximum heating capacity available in the Vivaldi Crescendo series?
The Vivaldi Crescendo series includes the CX160T model, which provides a heating capacity of 27 kW. This unit is designed for larger floor-plate or multi-zone applications, such as small industrial halls or large retail spaces. The CX160T operates as a heat pump, delivering both heating and cooling, and is supplied as a packaged unit to simplify installation. For lower capacity requirements, the Crescendo series also includes models like the CX100 (17 kW) and CX50 (7.71 kW), allowing for scalable system design.
Are Vivaldi PAC units suitable for commercial installations?
Yes, Vivaldi PAC units are engineered for commercial applications, with capacities ranging from 5.6 kW (e.g., HPX65 Harmonie) up to 27 kW (e.g., Crescendo CX160T). These units are designed to handle continuous operation and variable loads typical of offices, retail spaces, and light industrial environments. The inverter-driven models, such as the Concerto X65 Inv (9 kW), provide efficient part-load performance, which is critical for maintaining comfort while minimizing energy costs in commercial settings.
What refrigerants are used in Vivaldi heat pumps?
Vivaldi heat pumps use either R32 or R410A refrigerant, depending on the specific model and series. R32 is used in many newer models due to its lower global warming potential (GWP) compared to R410A. For example, the Harmonie HPX85 (7 kW) and Symphonie SX120 (18.82 kW) are designed with R32, while some older or higher-capacity models may still use R410A. Always refer to the technical datasheet for the specific model to confirm the refrigerant type, as this affects servicing and compliance with local regulations.
Can Vivaldi heat pumps be used for both heating and cooling?
Yes, Vivaldi heat pump models are designed for reversible operation, providing both heating and cooling. This is indicated by the 'Heat pump' designation in the product name, such as the Crescendo CX50 (7.71 kW) or the Symphonie SX120 Full Inv (18.82 kW). These units use a reversing valve to switch between cooling and heating modes, making them suitable for climates with seasonal temperature variations. Cooling-only PAC units are also available for applications where heating is not required.
What is the typical sound pressure level of Vivaldi PAC units?
Sound pressure levels for Vivaldi PAC units vary by model and capacity. For example, smaller units like the Harmonie HPX65 (5.6 kW) typically operate around 55–60 dB(A) at standard conditions, while larger units like the Crescendo CX160T (27 kW) may reach 65–70 dB(A). Inverter-driven models often have lower sound levels at partial load due to reduced compressor speed. Exact values are published in each model's technical datasheet, which should be consulted for acoustic design and compliance with local noise regulations.
