Its compressor consists of a vapour-compression refrigeration component (VCR) using an auxiliary airflow from the evaporative unit (EU) to cool the condenser, thus reducing the condensation temperature and thereby increasing energy efficiency of the refrigeration cycle. EU is a heat exchanger with a blower and a pump.
