GERMANY: Panasonic is to highlight its latest Aquarea J Generation heat pump running on R32 at next week’s ISH show in Frankfurt.
In addition to using the lower GWP R32 refrigerant, Panasonic says the Aquarea J Generation of air-to-water heat pump features an improved heating efficiency compared with the previous generation, achieving a COP of 5.33 on the WH-UD03JE5 model and a DHW COP of up to 3.30. Available from September 2019, the models will be rated A+++ in low temperature operation, the highest energy class, according to the new Energy Labelling Directive 2010/30/EC.
Aquarea J Generation can reach an output water temperature of 60˚C. With a sensor selector switch, the user has the option of setting the hot water supply so that Aquarea works with the best possible COP for DHW production. If a larger amount of hot water is needed, the controller optimises the unit for maximum bulk output.
In addition, the J Generation can cool down to 10°C and control the indoor comfort conditions via surface heating or a fan convector, more effectively. A special PV function also opens up the possibility of utilising free solar power for cooling of the building.
For intelligent maintenance support, Aquarea Service Cloud is available as part of the Aquarea Smart Cloud control system, which allows users to operate the Aquarea remotely via a smartphone. Aquarea Service Cloud saves time and installer visits by connecting Aquarea to the cloud to monitor remote error codes.
