Daikin adds R32 heat pump chiller

EUROPE: Daikin has now extended the use of R32 refrigerant to heat pump chillers, completing the Japanese air conditioning manufacturer’s Bluevolution R32 range.

The new range of EWYT-B air-cooled heat pump scroll chillers offer cooling capacities from 73.6kW to 349.7kW and heating capacities from 74.32kW to 389.9kW.

It will be available in two efficiency versions – silver and gold – and three sound configurations – standard, low and reduced.

The full load efficiency of this new series is said to reach a COP of 3.49 at nominal conditions). Special focus has been given to maximising seasonal efficiencies achieving SEERs up to 4.77 and seasonal SCOP efficiencies of 4.06.

Two different layouts are offered: parallel coil and double-V coil. The parallel coil units are equipped with continuous fan speed modulation to ensure precise airflow control and optimised condensing temperature. The double-V coil units are equipped with fan speed modulation as standard on the reduced noise units or on request for others.

The use of one or two independent refrigerant circuits with two or three compressors ensures reliability. 

The EWYT-B is fully compatible with Daikin on Site, Daikin’s cloud-based monitoring platform. This offers advanced functionalities including remote monitoring, system optimisation and preventive maintenance. 

Also, the new heat pump comes with master/slave functionality as a standard. This enables the management of up to four units on the same system without the need for external control devices. 

For more complex installations where there is a higher number of units and peripherals controls, an optional Daikin Intelligent Chiller Manager allows energy optimisation of the system. 

An extensive list of options and accessories provides further flexibility and choice. These include the fully integrated hydronic kit for fixed flow or variable flow operation, partial heat recovery for sanitary hot water production and many other solutions.
