Mac Museo La Coruña

The Gas Natural Union Fenosa Museum of Contemporary Art was inaugurated in 1995 as part of a large cultural center of the energy production company. It also included a second museum dedicated to energy.
In the last 10 years, almost half a million people walked through its halls as visitors or participants to various daily activities related to creativity.
The museum is also involved in the social field, with a program for people with disabilities, which involved more than 20,000 participants.

The control and maintenance of constant levels of temperature and humidity of the museum has been entrusted to a Clivet rooftop system composed of 4 air-air SMARTPACK heat pumps and 7 air-air ClivetPACK heat pumps, all equipped with electronic air filtration, thermodynamic energy recovery of the energy contained in the exhaust air and Free-cooling.

The heat pumps maintain temperature and humidity conditions in the parameters necessary for the correct conservation of the artworks:

• in winter, room temperature + 19°C ± 1°C, with relative humidity of 50% ± 5%;
• in summer, room temperature  + 26°C ± 1°C, with relative humidity of 50% ± 5%.

To avoid any problems regarding the conservation of the works and to guarantee the maximum comfort to visitors, the units are equipped with sensors to control the concentration of CO₂ in the environment. In this way they can adapt the air renewal to the crowding.

The entire plant is controlled by Clivet P-MATIC management and control system, which monitors the environmental conditions of the various rooms and activates the rooftop units only where and when needed, significantly reducing management costs.

The results

The new air conditioning system ensures the control and maintenance of constant levels of temperature and relative humidity both during the opening to the public and during the closing time, allowing the optimal conservation of the artworks.

Also the comfort of the visitors is maximum thanks to the combined action of the supervision system and the CO₂ probes that vary the volumes of fresh air according to the crowding of the various rooms.

The decentralization of the system and technological devices such as thermodynamic energy recovery and freecooling increase the overall efficiency of the system, reducing operating costs.

The packaged construction of Clivet air conditioning units, which are already tested in factory and equipped with all the main components of the system, simplified the installation operations and cut down the time of the new plant building, reducing the closure of the museum just to two months. The doors of the Museum were opened to visitors in time for the inauguration of the 14th Exhibition of Art Gas Natural Fenosa.
