Objective

1/ PROJECT OBJECTIVES AND SCIENTIFICAL TARGETS

Development of a European altemative for large gas fired or exhaust gas cogenerated LiBr absorption chiller heater to be integrated into buildings with following competitive advantages:

Thermal efficiency

Through modifications introduced into the standard thermal cycle:
- 25% improvement of the COP with subsequent primary energy saving - high efficiency operation from 10% to 100% load

Water consumption

Through separation of the absorber and condenser cooling circuits, development of a hybrid cooling tower:

- 50% reduction of water consumption

Benign impact on the environment

- 25% reduction of C02 emission at full load operation related to primary energy saving,
- down to 50% reduction of C02 emission at partial load,
- no water vapor wreath.

Integrability

- adaptable to cogeneration applications,
- adaptable to various chilled water circuits conditions,
- minimised overall dimensions,
- improved integrability of cooling water tower,
- conformity to European standards for buildings.
