High temperature & low carbon solution for heating decarbonisation
High temperature heat pump version with One and Two independent refrigerant circuits characterized by the optimised and compact design from 1 to 4 fans in line.
Installation flexibility
The new R-454C Small Inverter Heat Pump EWYE-CZ comes in four different layouts, all providing a very compact footprint despite the capacity they can deliver. That makes the series a great solution for projects dealing with space issues such as: residential, hotels and hospitals. No need for extra safety countermeasures due to the fact that the R-454C is an A2L refrigerant as the largely used R-32.
Product overview
The most complete and unique solution on the market for Decarbonisation. EWYE-CZ reaches 70 °C of heating water temperature even in extreme ambient conditions. That is, during winter season in Nordic Countries (low ambient temperature) and even in summer when Domestic Hot Water production would still be required. Moreover, EWYE-CZ can work in high delta T conditions allowing the supply of heating water to different heating applications in the installation space.
EWYE-CZ is available in 8 sizes from 16 to 70 kW capacity, all equipped with Daikin inverter scroll compressors. As well, fans used on EWYE-CZ are designed by Daikin. The product range also integrates an inverter water pump, facilitating installation operations and saving space.
The product is also available in reduced noise configuration, particularly suitable for noise-sensitive applications as: residential buildings, hotels and hospitals. Comfort heating can be supplied in many different applications, and on top of that EWYE-CZ allows domestic hot water production, including anti-legionella control function for the external storage tank.

Product Benefits
Daikin Core Technology
Daikin Scroll Compressors can benefit from Inverter technology that increases this Series’ efficiency performance, while the Vapor Injection with Economizer guarantees the Series Capacity steps and extended operating heating envelope.
Great energy efficiency levels are also granted by the Daikin Inverter Driven Fans, with high efficiency design glass reinforced resin maximize performances.
Daikin Inverter Scroll Compressors and Pump with Vapor Injection, make this new R-454C Small Inverter Heat Pump a full Inverter Series.
Daikin Tube & Fins (Cu/Al) Heat Exchanger: Reversible heat exchanger optimised for most extreme heating operation. Aluminum fins are covered by acrylic layer to ease flowing of condensate moisture and provide resistance to corrosion and protection from UV.

Optimised DeFrost Management
Integrated Defrost logic optimised for multiple units to sequence the non-simultaneity of the defrost cycle. Plant up to 4 units are optimised in terms of overall defrost impact:
Less plant water content
Higher customer comfort due to minimized temperature drop
Heating load uniformity over time
Low operating costs
Thanks to its Full Inverter design, this new unit can closely follow the cooling and heating load profile of the building. This is particularly important as it ensures low operating costs for the HVAC system at part load conditions, which represent most of the operating time.
F-Gas Ready Solution
The new Small Inverter Heat Pump provides low direct and indirect CO2 emissions levels. That makes it an environmentally friendly series, also thanks to the use of R-454C, which is known for being a low GWP (148) and sustainable refrigerant, fully compliant with the new F-gas regulation.
Contribution to Green Building
The most popular green building protocols are BREEAM and LEED. EWYE-CZ can contribute to project’s credits when evaluating energy efficiency of the hydronic system, thanks to inverter driven compressors. The limited GWP of R-454C also result in a possible contribution when evaluating the impact of refrigerants. On top of that, the Smart Grid accessory allows to control the heat pump maximizing consumptions when renewable energy is produced. Thereby, potentially resulting in credits under BREEAM and LEED protocols, as carbon footprint would be reduced.
