Abstract
(EN)
Provided is a refrigerant filling method that inhibits foreign matter and moisture from entering a heat source unit before a refrigeration cycle device is configured. In the refrigerant filling method, a refrigerant circuit that is configured by connecting a second heat source unit (10B) and a usage unit and in which a refrigeration cycle is performed by circulating refrigerant is filled with a refrigerant. The refrigerant filling method is provided with: a step in which the second heat source unit (10B) is filled with a first refrigerant before configuring a refrigerant circuit by connecting the second heat source unit (10B) to a usage unit; and a step in which the second heat source unit (10B) is connected to the usage unit, the refrigerant circuit is filled with a second refrigerant differing from the first refrigerant, and circulating refrigerant including the second refrigerant and the first refrigerant with which the second heat source unit (10B) has been filled is obtained.

Procédé de remplissage de fluide frigorigène qui empêche les corps étrangers et l'humidité d'entrer dans une unité de source de chaleur avant qu'un dispositif à cycle de réfrigération ne soit configuré. Dans le procédé de remplissage de fluide frigorigène, un circuit de fluide frigorigène qui est configuré par le raccordement d'une seconde unité de source de chaleur (10B) et d'une unité d'utilisation et dans lequel un cycle de réfrigération est effectué par un fluide frigorigène en circulation est rempli d'un fluide frigorigène. Le procédé de remplissage de fluide frigorigène est pourvu : d'une étape dans laquelle la seconde unité de source de chaleur (10B) est remplie d'un premier fluide frigorigène avant configuration d'un circuit de fluide frigorigène par le raccordement de la seconde unité de source de chaleur (10B) à une unité d'utilisation ; et d'une étape dans laquelle la seconde unité de source de chaleur (10B) est raccordée à l'unité d'utilisation, le circuit de fluide frigorigène est rempli d'un second fluide frigorigène différant du premier fluide frigorigène, et un fluide frigorigène en circulation comprenant le second fluide frigorigène et le premier fluide frigorigène avec lequel la seconde unité de source de chaleur (10B) a été remplie est obtenu.
