Background
Housed in a building built in the year 1883, neoclassical style, was one of the
first palaces that were built in one corner of the District of l'Eixample in
Barcelona. The 5* Grand Luxe hotel, which opened its doors in 1992, integrates
the façade of the old palace with a modern glass structure. In 2012 the building
replaced its existing air-conditioning system with Panasonic’s ECOi system. The
120-room hotel also has a gallery of Egyptian art from the collection of Jordi
Clos.
Challenge of the project
The challenge presented by this project was to replace an existing VRF system
without affecting the normal activity of hotel. The main objectives were to
reduce running costs, provide a more comfortable atmosphere with more precise
temperature control, and quieter operation for guests. In addition, the
property required excellent after-sales service, 24 hours a day, 365 days a
year.
The solution
The heat recovery system is ideal for a hotel of this category. A smart
combination of 2 pipe and heat recovery units significantly reduced the
investment costs, without affecting the requirements of comfort. Thanks to the
modularity of the system ECOi, the installation was performed plant-by-plant
without affecting the normal activity of hotel.
Control
The integrated system control was provided by the KNX/EIB interface and in
addition, a central touch panel with web server (CZ-256ESMC2) was installed for
centralized system control
