Leading the way in reducing environmental impact: Daikin’s adds to its unique Bluevolution R-32 heat pump range

First in the market to introduce air-to-water heat pumps with R-32 refrigerant, Daikin raises the bar with the release of a new series which completes the Daikin Bluevolution R-32 range.

Extending to the existing the Daikin Bluevolution range with R-32 for cooling only and free cooling, the new air to water heat pump series offers options ranging from 80kW to 670kW heating capacities.

The new Daikin heat pump series will be available with two efficiency versions (Silver and Gold), combinable with three sound configurations (Standard, Low and Reduced) and providing full customisation on project-specific requirements.

Reduced running costs

The full load efficiency of the new series goes up to 3.5 COP (at nominal conditions). Specific focus during the design has been given to maximize the seasonal efficiency (part load conditions) and consequently reducing the running costs. More specifically seasonal cooling efficiency (SEER) goes up to 4.7 and seasonal efficiency in heating operation is reaching 3.9 (SCOP).

Greater scalability and choice with smart functionality

The new series is fully compatible with the Daikin on Site cloud-based platform, which offers advanced functionalities including remote monitoring, system optimization and preventive maintenance.

Additionally, the new heat pumps come with Master/Slave functionality as standard, which enables the management of up to 4 units on the same system without the need for external control devices.

For more complex installations, for example where there is a higher number of units and peripherals controls, the optional Daikin Intelligent Chiller Manager allows energy optimisation of the system and, when necessary, full customisation of control solutions to the specific installation’s needs.

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.

R-32 – a better choice

R-32 refrigerant (chemical name difluoromethane, also called HFC-32) is a safe, environmentally friendly alternative for the future, with a Global Warming Potential (GWP) of just 675, which is only a third of the more commonly used R-410A.

Daikin is a pioneer in the use of R-32 refrigerant for heating and cooling applications in HVAC. The first to introduce R-32 in split air conditioners in 2012, the company has since expanded the range of R-32 solutions to include commercial air conditioners and heat pumps.

Thanks to its lower GWP, R-32 allows Daikin to minimise the environmental impact of its highly energy-efficient scroll compressor chillers.

With a lower flammability classification (R-32 refrigerant falls into category class A2L in ISO817),
R-32 can be safely used in many applications including chilled water systems. As a single component refrigerant, R-32 is also easier to recycle and reuse, another environmental plus.

Daikin’s Refrigerant Policy

Daikin has a long history of working to reduce the environmental impact of cooling, heating and refrigeration products, to which it brings unique expertise that comes from manufacturing both refrigerants and equipment. This tradition reflects the company’s corporate philosophy to «Be a Company that Leads in Applying Environmentally Friendly Practices».

Daikin believes in diversity of refrigerant choice, to allow the best solution to be used in each application. In determining refrigerant choice, Daikin is assisted by its experience in using fluorinated (HFC, HFO) as well as non-fluorinated gases (ammonia, carbon dioxide, hydrocarbons).
