Title:
冷媒充填方法
Document Type and Number:
Japanese Patent JP7164822
Kind Code:
B2
Abstract:
Efficiency in refrigerant charging work is addressed when a refrigerant recovered from the first heat source unit is to be charged to a second heat source unit. In a refrigerant charging method in which a first heat source unit (10A) of an already installed refrigeration cycle apparatus in which a refrigeration cycle is to be performed by a refrigerant that circulates is replaced with a second heat source unit (10B), a step of transferring the refrigerant from the first heat source unit (10A) to the second heat source unit (10B) is included. In addition, a step of measuring the weight of the refrigerant that is transferred from the first heat source unit (10A) to the second heat source unit (10B) is included.
