Abstract

MéTODO DE MONITORAR A OPERAçãO DE UM CICLO DE REFRIGERANTE, E, CICLO DE REFRIGERANTE. Um ciclo de refrigerante (20) tendo um compressor (22) comprimindo um refrigerante para um condensador a jusante (24). Um ventilador (25) insufla ar sobre o condensador (24). Tipicamente, o condensador é um trocador de calor exterior. Do condensador (24) o refrigerante se propaga para um dispositivo de expansão (26), e o dispositivo de expansão (26) para um evaporador (28). O evaporador é um trocador de calor interior.
