Daikin Mini Chiller Systems Air-cooled minichiller with inverter

The series of Daikin Minichillers dedicated to residential or small commercial applications, with capacities from 5 kW to 13 kW nominal, uses the Inverter as a distinctive feature. The hermetic Swing compressor for the sizes 005-007 kW and Scroll for the subsequent 009-013 kW is driven by Inverter as are the unit's fans. High performance is therefore achieved at partial loads, control of the water delivery temperature at a fixed point, which can be exploited, for example, for radiant panel systems, and excellent acoustic performance at partial loads thanks to the simultaneous reduction in noise emission of both the compressor and of fan. The water content necessary for the correct operation of the unit is reduced thanks to the Inverter, and can guarantee operation even without inertial accumulations. The water-refrigerant exchanger has brazed plates

Why the inverter?

The Inverter allows you to continuously modulate the power supplied by the compressor based on the thermal load requests, varying its number of revolutions. This principle, compared to traditional technology which divides the power into discrete steps of even high capacity, guarantees the end customer energy savings and better control of the operating parameters of the system. Most of the time, a building's cooling demand is less than the system's maximum load capacity. The larger the variations in annual load, the more vital it is to ensure that units are operating efficiently.

Energy Savings 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 most of the time, guaranteeing the best performance and reaching high values average summer seasonal yield ( ESEER ).

Ideal Temperature Continuous adjustment 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 perspective 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 partially, i.e. in conditions of lower demand for power output, 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 the thermal inertia to be reduced, with energy optimization and shorter commissioning times. This results in significant savings in system costs as the storage 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 nominal operating current, on which a lower cost for the supply of electrical components to be installed depends

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 getting the system up to speed but, above all, it 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 external temperatures. Inverter heat pumps can benefit from greater power when the environmental conditions require it, losing only 15% of yield in the transition from 7°C to -10°C of external air (in the case of ON-OFF the reduction would be ~40%), guaranteeing a water temperature of 50°C at all speeds. These advanced heat pumps can therefore be considered "primary", since they allow us to avoid the use of boilers.

Scroll compressor

Scroll compressors are equipped with two spirals, one remains fixed while the other orbits eccentrically without rotating. Designed for small and medium capacities, they guarantee constant reliability and high efficiency throughout their operational life

Characteristics

• Simple, compact and robust
• Absence of valves and oscillating joint mechanisms, to guarantee maximum reliability
• Constant compression, to ensure a low level of energy consumption
• Greater compression efficiency thanks to the absence of volumetric expansion
• Low sound level
• Low starting current
• The Scroll compressor is suitable for the use of the Inverter, as in the range up to 13 kW, being able to guarantee high ESEER values, absence of peaking and precise control of the outlet water temperature

Advantages:

› Extraordinary efficiency at part load

› Inverter technology to guarantee low noise and highest ESEER values ​​in the class

› Wide operating range

› Integrated hydronic systems

› Easy “plug and play” installation

› Single-phase power for residential applications, three-phase power model available for small commercial applications
