Our product solution ReCooler Heat Pump Index
Integrated cooling Why ReCooler HP? One package Ease of installation One responsibility Imbeded in AHU More efficient Energy Recovery Compact No additional fan Aesthetical Cooling and heating function Higher efficiency than chillers and condensing units Inverter drive and PM scroll compressors Reduces compressors load High energy recovery (winter/summer)
Technical Features Components and Function Index
Why is Recooler HP Unique? Exhaust coil Control Dedicated electrical cabinet Splitable casing (option) SEMCO Rotor Inverter Drive Reversing valve Permanent Magnet Scroll compressor Inlet coil ReCooler HP integrates best components for cooling, heating and energy recovery
How ReCooler works? (Example in cooling mode) 41 C 30 C 25 C 32 C 27 C 18 C 19 C Less consumption SEMCO rotor reduces load Less complexity no extra fan,pumps & piping Packaged no condenser on roof top More efficient Lower temperature on condenser
How ReCooler works? (Example in heating mode) -8 C 0 C 22 C -5 C 16 C 23 C 24 C Less consumption SEMCO rotor reduces load Less complexity no extra fan,pumps & piping Packaged no condenser on roof top More efficient Higher temperature on Evaporator
Compressor Single compressor per circuit Reliable operation PM Scroll Compressor * Lower maintenance** Higher efficiency** Reliable operation** * Except size 008 = PM Rotary compressor ** Compared to piston compressors and asynchronous motors
Inverter Drive Inverter drive Best Part load efficiency Stable Air temperature Low starting current Power factor close to 1.0
Control Control Software Components protection Adaptive control Modbus or Analogic communication 2 X Electronic Expansion Valves Pressure and temperature transducers Flexible control Refrigerant charge control Easier maintenance
Engineered design (Compressors and Piping) Refrigerant piping design Compressors are out of Airflow Easier maintenance
Electrical Panel Dedicated to ReCooler o All power switches (High voltage) o Controls (low voltage) Out of airflow Control over operations Easier maintenance Dedicated fan for ventilation Increased safety Fläkt Woods control system ensures a reliable and stable system with a long life
SEMCO Wheel Highest energy recovery High sensible energy recovery performance High latent energy recovery performance Reduction of cooling need Reduction of electricity sizing for cooling
SEMCO Wheel Comfort & Reliability Less sensitive to cold climate Balanced humidity indoor climate Allows performance in high OAT
Performances Nominal heat pump capacity (not including recovery wheel) Size Cooling capacity Heating capacity 008 11.0 kw 12.8 kw 011 16.4 kw 18.6 kw 018 21.3 kw 23.2 kw 023 28.3 kw 28.5 kw 032 38.5 kw 32.7 kw COP up 6.1 EER up to 18 including rotor EER up to 5.1 EER up to 22 including rotor Operating limits ( external temperatures) Cooling Heating Min 20 C -5 C Max 40 C 15 C
Concerning Areas where temperatures goes below -5 C In order to pass some period where external temperature goes below -5 C an electrical heater can be proposed: The unit will not require any additional site work If hot water is available nearby then a water coil can be proposed instead.
