AIR CONDITIONER, HEAT SOURCE UNIT, AND AIR CONDITIONER UPDATE METHOD

摘要

To provide a configuration and updating method capable of promptly detoxifying acid components remaining in existing refrigerant pipes of a separate-type air conditioner when the existing refrigerant pipes are appropriated to update an outdoor unit and indoor units. An air conditioner (101) is an air conditioner configured by appropriating, as existing refrigerant pipes, refrigerant communication pipes (6, 7) configuring an existing air conditioner (1) to update indoor units (4, 5) and an outdoor unit (2) configuring a refrigerant circuit (10) of the existing air conditioner (1), and is disposed with an updated refrigerant circuit (110) and a mixer (191) disposed in the updated refrigerant circuit (110). The updated refrigerant circuit (110) is filled with working refrigerant and refrigerating machine oil that include an acid trapping agent that detoxifies acid components remaining in the refrigerant communication pipes (6, 7). The mixer (191) mixes the acid components with the acid trapping agent during refrigeration cycle operation of the updated refrigerant circuit (110).
