Continent Baie Mahault (Guadeloupe)

STL overcomes low electrical supply capacity and
achieves high running cost savings


Continent Baie Mahault


 

 With 10 000 m² of air conditioned space, Continent has the biggest air conditioning installation in Guadeloupe.
     Guadeloupe has tremendous difficulties to produce electricity at low cost. The peak electrical tariff is 4 times more expensive than the night tariff.
To overcome this difficulty it was decided to install a Cristopia Thermal Energy Storage System (STL) to shave more than 50% of the cooling demand and to supply the full demand during electricity peak period.
Thanks to the STL the electrical installation was reduced and large savings have been achieved on the operating costs.

An STL is used for shaving the cooling demand during the electricity peak period and for reducing the electrical equipment.

Technical Data

Daily Cooling Energy Consumption : 13 900 kWh
Maximum Cooling Demand : 1 540 kW at 7/12°C
Cooling Energy Stored : 6 600 kWh
Store Type : STL - C - 120
Storage Temperature : 0°C
Nodule Type : C - 00
Number of Tanks : 2
Tank Diameter : 2.5 m
Tank Length : 13.7 m

Characteristics

The STL is composed of two 60 m³ tanks in series (these being in parallel with chiller).
The STL stores 6600 kWh daily. The parallel layout allows all the storage strategies (total storage, partial storage, time of the day).

The aim is to maximize the running cost savings.

The management of the system is achieved by a sophisticated BMS for optimum efficiency.

Technical Advantages

Smaller chiller capacity
Smaller air cooled condensers
Simplified servicing
Back up at disposal
Reduced electrical installation
Flexible system available for efficient energy management
