Abstract

Dispositivo frigorífico en condiciones de funcionamiento variables que comprende, en un circuito frigorífico clásico, además del clásico capilar (1), un segundo órgano de expansión como el capilar (2), que extrae una parte de los gases a alta presión saturados cuando las condiciones de funcionamiento reales son más elevadas que las condiciones de funcionamiento nominales. Aplicación a la realización de climatizadores de aire ambiente o de grupos frigoríficos.
