Glossary
Absorption chillers and heat pumps- ammonia-water systems. Technology

COP; coefficient of performance

Ratio between the useful power produced (cooling or heating) and the total power consumed (electrical and thermal).

COA; coefficient of amplification

Ratio between thermal power produced (in heat pump mode) and total power consumed (electrical or thermal). Equivalent to COP_hot.

EER; energy efficiency ratio

Ratio between the cooling power produced (in refrigeration mode) and the total power consumed (electrical or thermal). Equivalent to COP .

GUE thermal efficiency; gas utilization efficiency

Ratio between the useful power produced (cooling or heating) and the gas power consumed.

Générateur-Absorbeur-Échangeur de chaleur GAX ; Generator-Absorber-Heat eXchanger

Component of the eponymous cycle combining, in the same exchanger, a desorber (generator) and an absorber (absorber).
