Name of technology example:		Type
Chillers		☑ Energy Efficiency ☑ Renewable Energy ☐ Alternative Methodology

Description	A chiller is a machine that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle. This liquid can then be circulated through a heat exchanger to cool air or equipment as required. As a necessary byproduct, refrigeration creates waste heat that must be exhausted to ambient or, for greater efficiency, recovered for heating purposes. Concerns in design and selection of chillers include performance, efficiency, maintenance and product life cycle environmental impact. Existing chiller technology can be operated with renewable energies. New environmental friendly refrigerants like NH4 (amonia), CO2, Propane or water will gain more and more importance. Cooling is responsible for almost 15% of the worlds electricity consumption. The energy saving potentials are high.
