Daikin new small inverter Split-Chillers EWYT~CZI+EWYT~CZO with R32 refrigerant (models from 21 to 90 kW) replace the current R410A Daikin inverter Split heat pumps SEHVX~BW+SERHQ~BW. This new version will offer the exact same energy efficiency performances and end the environmental sustainability features offered by the R-32 Small Inverter Chiller in the packaged version, extending its application possibilities to glycol free installations in cold climates. The Air-Cooled R-32 Split-Chillers will be available in the heat pump version, delivering cooling and heating capacities from 16 kW to 90 kW. The compactness, the wide operating envelope, and the high energy efficiency, will still be the main strengths this new version, still standing out for providing the best efficiency levels in the market, both in cooling and heating mode, and the lowest direct and indirect CO2 emission levels.
Quiet operations, reduced footprint, advanced connectivity, and wide operating limits make the new R-32 Small Inverter Chiller an ideal solution for a wide range of HVAC projects, from comfort to process applications. Heat pumps are designed to cope with an extended ambient temperature range of -20 ˚C to 35 ˚C, and can produce hot water up to 60 °C. Notable among the outstanding features offered as standard by this Series are the Daikin design DC-Inverter Scroll compressors, the optimized Cu-AI Coils and the brazed plate heat exchangers. Also included within the unit are high efficiency Daikin design DC-Inverter fans with a selectable silent mode, and an inverter pump kit. Besides, the Split version will allow components such as expansion valves, pumps and heat exchangers, to be placed in a dedicated box, specifically designed for indoor installation, to protect components and piping from cold weather, and allow glycol free installation even in extremely cold climates.
The Smart Control solutions for this Series are specifically designed to reach the highest level of performance and system flexibility.The R-32 Small Inverter Chiller can communicate with any external BMS and offers the Master and Slave option as a standard – allowing to sequence and connect up to 4 units with one of them selected as Master unit. The new Series also stands out for its enhanced ability to connect to the Internet through the Internet of Things. In fact, a dedicated Mobile Configuration App can be used to make commissioning extremely easy and quick. The Smart Control Solutions for the new Small Inverter Chiller also include Daikin on Site, the remote monitoring and system optimization within the Daikin proprietary cloud platform, which ensures full control of the units through detailed monitoring, online alarm troubleshooting and remote control.
