Clivet high efficiency system for new industrial plant
A
t the beginning of 2015, Decathlon decided to replace its logistic store in Basiano, Milan, with a larger one:
40,000sqm of surface, 15,000sqm of multi level mezzanine, 4,000sqm of offices, common rooms, technical premises and 1,200sqm of regional workshop dedicated to repairs. They also added an outdoor area with 460 parking spaces and a loading / unloading area with over 40 doors.
In order to meet the high performance required, 17 CLIVETPack²
CSRN-XHE2 high
efficiency direct expansion packaged air conditioning systems for medium crowded areas were installed.
The challenge
This project was designed to achieve some ambitious goals: ■ Create a center of excellence, ensuring maximum well-being for operators.
■ Reduce the environmental impact, favouring the exploitation of renewable energies in order to build a ‘Green’ building.
■ Reduce the overall cost of the plant, both capital investment and year round operation.
The solution The system consists of 17 high-efficiency
direct expansion packaged air conditioning systems CLIVETPack²
CSRN-XHE2 with the
outdoor units installed on the roof of the building.
The units are equipped with advanced technologies for energy saving, such as thermodynamic energy recovery on the exhaust air, double refrigeration circuit with modular scroll compressors, a device for the reduction of the consumption of external section fans, and high efficiency diffusers for axial AxiTop fans.
The units are managed by two Clivet Master System Management Systems, the remote control system dedicated to packaged air conditioning units.
Through a single controller with touch display, the system allows access to all the system and unit status information.
The results
The operator comfort is granted by advanced air conditioning systems. The new site is heated and fully air-conditioned, uncommon features in logistic areas. The air conditioning systems were also designed to ensure optimum comfort independently from external climatic conditions, which are very variable. The Decathlon logistic site in Basiano has obtained the Class A energy certification,
thanks to low-consumption technologies using renewable energy such as heat pumps. The green objectives of the site were also respected; heating and air conditioning are assured by clean energy thanks to the heat pumps. Plant management costs are greatly reduced. Temperature and humidity are automatically controlled, saving money thanks to high efficiency units and energy recovery. All systems were designed following rationality, functionality and well-being principles, in compliance with all applicable regulations.
In particular, air conditioning and ventilation systems were set up to cut down energy consumption and management costs, while increasing ease of operation and maintenance, in accordance with the complex operating requirements.
Clivet’s decentralised solution dramatically reduced the installation costs, while increasing its versatility and reliability, as each served area is completely independent from the others.
The adoption of a decentralised system with monoblock units, integrating most of the components of the plant, accelerated the time of realisation and reduced the initial investment.
