REFRIGERATION AND AIR-CONDITIONING DEVICE

摘要

A refrigerating and air-conditioning apparatus that achieves reduced limitations with respect to the communication of indoor units and can identify which indoor unit is connected to each branch port is obtained. Indoor units 2 are made to operate on a one-by-one basis, and it is identified which indoor unit 2 is connected to each branch port 6 on the basis of the difference between an inlet temperature and an outlet temperature at the branch port 6 at that time.
