Total Recool: Air handling units need no add-ons


Recooler HPIn this sponsored post Fläkt Woods details how its Recooler HP is fitted with the latest generation of Semco hygroscopic wheel, and also with DC inverter scroll compressor technology and electronic expansion valves, maximising efficiency and comfort.

Fläkt Woods’ Recooler HP is designed as an integral component to Fläkt Woods’ range of air handling units. Recooler HP incorporates a reversible heat pump and a recovery wheel to provide a host of benefits, including quick and easy installation, high efficiencies and all-year-round energy recovery.

Using a DC inverter scroll compressor, the Recooler HP can achieve a Coefficient of Performance (COP) of up to 6.5, as well as full control of output from 10% to 100%. This enables the air handling unit to deliver the exact temperature required and maintain end user comfort levels more effectively than traditional fixed speed systems. In addition, the inverter drive allows the unit to work at part load, ensuring the perfect balance between reliability and efficient heating and cooling.

The innovative integral recovery wheel within the Recooler HP offers a maximised level of energy recovery, with efficiencies over 83%. Plus, with the capability to operate at lower temperatures and still recover energy in winter mode, the unit ensures reduced heat loss during colder weather and less maintenance for defrosting.

David Black at Fläkt Woods explains: “Recooler HP has been designed to seamlessly integrate with an air handling unit, allowing installation on site, without the need for groundwork or additional preparation.

“Crucially, we wanted to design a compact ‘all in one’ product that ensures quick and simple installation, as well as high efficiencies that will ultimately reduce end user energy bills.

“With Recooler HP, there is no requirement for additional chillers, boilers or to install any pipework, which means the unit is quickly ready to operate once the electrical connections have been made. In addition, noise and energy consumption is further reduced as there is no need for an outdoor condenser fan.”

For even further efficiency, the Recooler HP is supplied with a sophisticated adaptive control unit, loaded with intuitive software that has been developed to maintain the ideal operating map. This manages two expansion valves for full control of cooling and heating modes, as well as refrigerant charge. The control unit also incorporates electronic transducers for temperature and pressure to maximise reliability and efficiency.

Recooler HP is available in seven sizes with nominal cooling capacities (rotor and compressor) from 35kW to 175kW and nominal heating capacity (rotor and compressor) from 21kW to 57kW.
