WTW R32 heat pump offers modular advantage
3rd April 2024
EUROPE: Daikin Applied has released details of a new range of water-to-water R32 heat pumps with a new modular design for additional configuration flexibility.
Breaking away from the more traditional package solution, the modular approach with the new EW*T-Q-X-A1 range allows the required capacity to be reached by combining smaller units piped together and controlled as a single unit.
The modular construction is said to offer significant benefits in siting and installation, making units easier to transport, handle and position up to a fully plug and play solution by including the Daikin manifold kKit and pump module.
Hot water production is up to 60°C, whilst chilled water is supplied in the range from -15°C (water-glycol mixture) to 30°C evaporator leaving water temperature.
Composed of three base modules offering 100kW, 125kW and 160kW capacities, the range features Daikin scroll compressors and is available in two sound versions.
Unit configurations by type include water-to-water heat pump with inversion on the water side, water-to-water heat pump with inversion on the refrigerant side (100kW only) and condenser-less.
Thanks to its modularity, the new EW*T-Q-X-A1 offers the potential for scalability, reducing initial investment costs while opening up the possibility for future expansion with additional modules installed as building occupancy increases.
The common scroll layout ensures greater compatibility, helping to promote system longevity and making future system upgrades effortless. The modules can be combined as a side-by-side array or stacked to minimise space requirements.
Each of the modules is compact and easily transportable. The single module measures 1200mm wide, 1300mm deep and 1000mm high and can be easily handled with a forklift.
Installation
Use of the the Daikin manifold kit enables modules to connect on the water side. Each manifold is equipped as standard with manual isolation valves for all connections, enabling each single module to be isolated during maintenance without shutting down the entire system.
A dedicated pump module equipped with inverter pumps and 18 litre expansion tank can also be added.
