Daikin Mini Chiller Systems Small chilled or heated water production systems

Why the inverter?

The Inverter allows the compressor power to be continuously modulated based on thermal load requirements by varying its rpm. This principle, compared to traditional technology that divides the power into discrete steps of even high capacity, guarantees the end customer energy savings and better control of the system's operating parameters. Most of the time, a building's cooling requirement is less than the system's maximum load capacity. The greater the variations in annual load, the more vital it is to ensure that the units operate efficiently.

Energy Saving Absorption proportional to the power supplied

The Inverter offers, for the chiller as a whole, the possibility of significantly increasing its efficiency at partial loads, that is, the condition in which, seasonally, the chiller will work for most of the time, guaranteeing the best performance and reaching high values ​​of average summer seasonal efficiency ( ESEER ).

Furthermore, with the introduction of the European SCOP (seasonal COP ) indicator, the adoption of modulating systems and inverter technology allows for the optimisation of consumption even in winter, in line with the best requirements requested by the new energy index.

What is SEER?

«Seasonal Energy Efficiency Ratio» ( SEER ): the seasonal energy efficiency ratio of the unit representative of the entire cooling season, calculated as the reference annual cooling demand divided by the annual electricity consumption for cooling purposes.

New parameter representing the seasonal efficiency of the product . The SEER value is calculated over a period of 2600 hours of operation during the year. Of these, only 30 hours of operation at full load are recorded.

Ideal Temperature Continuous power and noise regulation

The ability to work in modulation offers the guarantee of accurate control of the fluid temperature, regulated at a fixed point on the delivery to the system. This feature is ideal for industrial applications and precision temperature control, as it excludes constant compressor stops/starts, responsible for electrical and mechanical wear. A further advantage is the lower acoustic impact when compressors and fans operate partially, or in conditions of lower power output demand, while ensuring greater stability for the water temperature.

Lower System Costs Reduction of system water accumulation/content (-60%)

Thanks to the ability to react quickly to load variations, chillers that use Inverter technology can work correctly with a strong reduction in water content in the system (-60% compared to traditional chillers). This allows for a reduction in thermal inertia, with energy optimization and shorter start-up times. The result is a significant saving in system costs as the accumulation tank is no longer necessary.

Electrical advantages

From an electrical point of view, the Inverter introduces two great advantages:

Low inrush currents, significantly lower than the nominal operating current, which results in a lower cost for the electrical components to be installed

More power available when needed

The Inverter allows you to vary the power supplied; by powering the compressor at a higher frequency it is possible to reach maximum power values ​​higher than the nominal ones. This offers benefits in the system's start-up but, above all, it becomes an evident technical plus when the machine works in extreme operating ranges. For example, traditional air-cooled heat pumps are usually combined with boilers to compensate for the efficiency deficit due to rigid external temperatures. Inverter heat pumps can benefit from greater power when the ambient conditions require it, losing only 15% of performance in the transition from 7°C to -10°C of external air (in the case of an ON-OFF the reduction would be ~40%), guaranteeing a water temperature of 50°C at all regimes. These advanced heat pumps can therefore be considered "primary", since they allow you to avoid the use of boilers.
