Project Summary: Air Handling Unit Modification at a Park Lane Hotel, London

Ecomec successfully delivered a comprehensive air handling unit (AHU) modification project at a prestigious and busy hotel in Park Lane, London.

The project was undertaken to enhance airflow delivery to the 1st-floor restaurant, addressing performance challenges by repositioning the heating and cooling coils and modifying associated pipework and valves.

Scope of Works

1. Isolation and Removal:
   • Disconnected chilled water (CHW) and low-temperature hot water (LTHW) pipework from the AHU.
   • Mechanically un-fixed and removed the existing heating and cooling coils from their original positions.
2. AHU Modifications:
   • Altered the internal configuration of the AHU to accommodate the new coil positions.
3. Pipework Rerouting:
   • Rerouted DN65 LTHW and DN80 CHW pipework to the new coil positions within the AHU.
   • Installed new isolation valves to enhance system control and maintainability.
4. Coil Relocation:
   • Successfully relocated the heating and cooling coils to their new positions within the AHU.
5. Access Enhancement:
   • Supplied and installed a new custom AHU door to provide easy access to the relocated coils.
6. Structural Repairs:
   • Repaired and sealed pipework penetrations in the AHU sections to maintain structural integrity and airflow efficiency.
7. Thermal Insulation:
   • Thermally insulated all pipework with 25mm insulation, finished with hammered aluminum cladding for durability and aesthetics.
8. Testing and Commissioning:
   • Filled, pressure-tested, and verified all pipework connections to ensure leak-free operation.
   • Brought the AHU back into service, ensuring optimal performance and improved airflow to the restaurant.

This project demonstrates Ecomec’s expertise in delivering complex HVAC solutions within high-profile environments, ensuring minimal disruption while achieving significant performance improvements.
