Aquarea K and L Series set benchmark
Panasonic unveils R290 A2W heat pump units The new K and L Series Aquarea A2W heat pumps from Panasonic are moving heat pumps to a new level of comfort and efficiency, with outstanding design and advanced features. Details of the new models were showcased recently at Chillventa with the actual units scheduled to come to the marketplace in the spring of 2023. The Aquarea L air-to-water heat pump is a major development for Panasonic as it employs propane as the refrigerant and features a hydraulic link between the outdoor and indoor unit. It is designed to maximise the properties of R290 refrigerant with its low GWP of 3. This facilitates a water outlet temperature up to 75°C even at -10°C outdoors, and domestic hot water of 65°C without an electric heater. According to Panasonic, this makes it particularly suitable for renovation and collective applications where a high temperature is required for radiators. Meanwhile, the new Aquarea K air to water heat pump uses R32 and retains a refrigerant link between the outdoor unit and the indoor unit.
The new K and L series models focus on improving energy performance, with the redesigned construction of both outdoor units being hermetically sealed for a high level of safety. Both generations are said to benefit from a reduced noise level of up to -8dB(A) on previous models. They also offer higher levels of performance, boasting an improved SCOP of up to 5.12. Focusing on improving installer and user experience, the latest generations incorporate a new remote control supplied as standard and feature intuitive navigation for ease of use. There is also an optional second remote control available for twozone systems. The systems will also have the ability for smart control and energy consumption monitoring.
