要約
(EN)
A refrigeration cycle device (1) circulates refrigerant, which is a non-azeotropic refrigerant mixture, in a refrigeration cycle in which a compressor (21), a condenser (22), an expansion valve (23) and a vaporizer (24) are connected by refrigerant pipes, wherein during the running of a refrigeration cycle, circulation composition values are calculated on the basis of the states before and after a change in the refrigerant temperature and refrigerant pressure, a dT value that corrects a second temperature sensor (45) and a dP value that corrects a pressure sensor (44) are calculated according to a reference composition value and the circulation composition value of the refrigerant, the temperature value of the refrigerant at the outlet side is corrected using dT, the pressure value of the refrigerant is corrected using dP, and the refrigeration cycle is run.
(FR)
L'invention porte sur un dispositif pour cycle de réfrigération (1) qui fait circuler un fluide frigorigène qui est un mélange de fluide frigorigène non azéotropique, dans un cycle de réfrigération dans lequel un compresseur (21), un condenseur (22), un détendeur (23) et un vaporiseur (24) sont raccordés par des tubes de fluide frigorigène, dans lequel, pendant la marche sur un cycle de réfrigération, des valeurs de composition de circulation sont calculées sur la base des états existants avant et après un changement de la température du fluide frigorigène et de la pression du fluide frigorigène, une valeur dT qui corrige un second capteur de température (45) et une valeur dP qui corrige un capteur de pression (44) sont calculées en fonction d'une valeur de composition de référence et de la valeur de composition de circulation du fluide frigorigène, la valeur de température du fluide frigorigène au côté de sortie est corrigée en utilisant dT, la valeur de pression du fluide frigorigène est corrigée en utilisant dP et le cycle de réfrigération est exécuté.
