Panasonic cascade provides a new spin on efficiency

UK: Panasonic recently provided a large R290 air-to-water heat pump system to the National Wool Museum, located in a large remote site in South-West Wales. 

With funding provided by the Welsh government to replace the museum’s old gas-fired boilers, M&E contractor FP Hurley specified four Panasonic Aquarea 30kW TCAP M Series units, a first-of-its-kind installation in the UK.

Faced with limited outdoor space and being surrounded by residential properties, FP Hurley specified four Panasonic Aquarea 30kW M Series units that could meet the required capacity.

Selecting the high-temperature T-CAP technology with plug-and-play connection capabilities helped to streamline the project. The Panasonic M series units were easily able to integrate with the museum’s existing radiators, to deliver a high-water outlet temperature of up to 75°C and work in outdoor temperatures as low as -25°C. 

With the four 30kW Panasonic units working in cascade, the system is much more energy efficient. The Panasonic Cascade Controller can support up to 10 Aquarea air-to-water heat pumps, allowing run hours across multiple units to be shared by each unit.

“Utilising multiple cascade control connected heat pumps increases the flexibility of the system to support the fluctuating demand and maximises efficiency,” said Paul Taylor, Panasonic Heating & Cooling Solutions’ head of renewable heating.

The Panasonic Cascade Controller helps to maximise the lifespan of Panasonic Aquarea heat pump systems for large systems, as intelligent management balances the load and minimises downtime by offering a contingency solution if maintenance is required.
