HEAT TRANSFER DEVICE AND OUTDOOR MACHINE UNIT OF THE SAME DEVICE

摘要

PROBLEM TO BE SOLVED: To enhance the degree of connecting freedom of an indoor machine unit in rational structure. SOLUTION: An outdoor machine unit 1 is connected to an indoor machine unit 80 with a pipeline, thereby circulating a refrigerant discharged from a compressor. Branch pipes 60d and 60g, which communicate with an outdoor heat exchanger, are provided in the outdoor equipment unit 1. Refrigerant pipes 91a and 94a of an extension unit 90 are connected to branch pipes 60d and 60h by way of pipelines 101 and 102 on one hand while branch pipes 91b and 94b are connected to an indoor heat exchanger 81 of the indoor machine unit 80 by way of refrigerant pipes 82a and 82b. This construction makes it possible to connect a plurality of indoor machine units 80 to the extension unit 90.
