Integrated cooling

Why ReCooler HP?

One package

Imbeded in AHU

More efficient

Energy Recovery

• Ease of installation • One responsibility

• 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)

Why is Recooler HP Unique?

Inlet coil

Permanent Magnet Scroll compressor

SEMCO Rotor

Inverter Drive

Dedicated electrical cabinet

“ReCooler HP integrates best components for cooling, heating and energy recovery”

Exhaust coil

Splitable casing (option)

Reversing valve

Control


How ReCooler works? (Example in cooling mode)

Less complexity – no extra fan,pumps & piping

Packaged – no condenser on roof top

More efficient – Lower temperature on condenser

Less consumption – SEMCO rotor reduces load

32°C 27°C 18°C 19°C

25°C 30°C 41°C


How ReCooler works? (Example in heating mode)

Less complexity – no extra fan,pumps & piping

Packaged – no condenser on roof top

More efficient – Higher temperature on Evaporator

Less consumption – SEMCO rotor reduces load

-5°C 16°C 23°C 24°C

22°C 0°C -8°C


Compressor

Single compressor per circuit

Reliable operation

Lower maintenance**

Higher efficiency**

Reliable operation**

* Except size 008 = PM Rotary compressor ** Compared to piston compressors and asynchronous motors

PM Scroll Compressor *


Inverter Drive

Inverter drive

Best Part load efficiency

Stable Air temperature

Low starting current

Power factor close to 1.0


Control

Control Software

Flexible control

Refrigerant charge control

Easier maintenance

Components protection

Adaptive control

2 X Electronic Expansion Valves

Pressure and temperature transducers

Modbus or Analogic communication


Engineered design (Compressors and Piping)

Compressors are out of Airflow

Easier maintenance

Refrigerant piping design


Electrical Panel

• Dedicated to ReCooler o All power switches (High voltage) o Controls (low voltage)

• Out of airflow

• Dedicated fan for ventilation

Easier maintenance

Control over operations

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

Allows performance in high OAT

Less sensitive to cold climate

Balanced humidity indoor climate


Performances

• Nominal heat pump capacity (not including recovery wheel)

• 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)

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

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.
