Daikin Mini Chiller Systems Small systems for the production of chilled or heated water
Why the inverter ?
The inverter allows you to continuously modulate the power supplied by the compressor based on the thermal load requests, varying the number of revolutions of the same. This principle, compared to the traditional technology which divides the power into discrete steps of even high capacity, guarantees the final customer energy savings and better control of the operating parameters of the system. Most of the time, the cooling demand of a building is less than the maximum load capacity of the system. The larger the variations in yearly load, the more vital it is to ensure units are operating 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, i.e. the condition in which, seasonally, the chiller will work for most of the time, guaranteeing the best performance and reaching high values average seasonal summer yield ( ESEER ).
Furthermore, with the introduction of the European SCOP (seasonal COP ) indicator, the adoption of modulating systems and Inverter technology makes it possible to optimize consumption even in winter, in line with the best requirements of the new energy index.
What is SEER?
'seasonal energy efficiency ratio' ( SEER ) means 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 representative of the seasonal efficiency of the product . The SEER value is calculated over a period of 2600 operating hours during the year. Of these, only 30 hours of full load operation result.
Ideal temperature Continuous regulation of power and noise
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 from the point of view of industrial application and precision temperature control, as it excludes the constant stops/starts of the compressors, responsible for electrical and mechanical wear. A further advantage is represented by the lower acoustic impact when compressors and fans operate partialised, i.e. in conditions of lower demand for power supplied, while ensuring greater stability for the water temperature.
Lower Plant Costs Reduction of water accumulation/content of the plant (-60%)
Thanks to the ability to react quickly to load variations, chillers that use Inverter technology can work correctly with a strong reduction in the water content in the system (-60% compared to traditional chillers). This makes it possible to reduce thermal inertia, with energy optimization and shorter start-up times. This results in 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, considerably lower than the rated operating current, which results in a lower cost for the supply of electrical components to be installed
More power available when needed
The inverter allows you to vary the power supplied; by feeding the compressor at a higher frequency it is possible to reach maximum power values higher than the nominal ones. This offers benefits in bringing the system up to speed but, above all, becomes an evident technical plus when the machine works in extreme operating fields. For example, traditional air-cooled heat pumps are usually combined with boilers to compensate for the efficiency deficit due to cold outside temperatures. Inverter heat pumps can benefit from greater power when ambient conditions require it, losing only 15% of output in the passage 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", as they make it possible to avoid the use of boilers.
