Intellihot’s Electron is a tankless heat pump water heater designed for commercial use. The scroll compressors used offer a wider range of turn down, and use Fujitsu’s unique sensor-less sine wave control method to control compressor input power, improving efficiency and lowering decibel levels. Greater indoor comfort is achieved through intelligent refrigerant control corresponding with the heat load of the room. Also, compressor control logic manipulates inverter speed to balance the mass airflow rate of refrigerant in each outdoor unit. Compressor life cycle is increased due to the Airstage VU-V controls’ ability to rotate the starting unit across the modules in a system. A new service window provides instant access to the PCB switches and error indicator. The Airstage VU-V also offers a maximum connected refrigerant pipe of 3,280 feet. We can also go from minus 15° to 126°, making these units applicable in climates ranging from those found in Michigan to those found in Arizona.” This increases our tonnage from 24 tons to 36 tons, bringing us to a larger capacity. “With the flip of a switch, you can choose to have the system act as a two-pipe system or a three-pipe system for heat recovery. “This is both heat pump and heat recovery in the same chassis,” said Terry Lawrence, sales manager, Fujitsu General America Inc. As many as 64 indoor units can be connected to a single system. The new VRF platform offers broader size ranges, with single modules from 6-16 tons and up to 36 tons per combined system. Efficiency is the heart of sustainability and Daikin’s legacy.”įujitsu’s Airstage VU-V outdoor units can serve either as heat pump or heat recovery systems with simple setting changes and the addition of refrigerant branch units (RBUs). So, it’s important to make these systems as efficient as possible. “HVAC systems account for roughly 40%-60% of energy consumption and associated emissions on a day-to-day basis. “From homes to high-rises, the climate impact of buildings is largely tied to their ongoing operation,” said Philip Johnston, general manager of environmental business development center at Daikin.
