<p>PROBLEM TO BE SOLVED: To efficiently carry out checking work on the connecting state of a multizone air conditioner by controlling the operations of the air conditioner. SOLUTION: After the preoperation temperatures of pipelines 80a, 80b, and 80c respectively connected to a plurality of indoor heat exchangers 71 are inputted, one of the pipelines 80a, 80b, and 80c is selectively opened by driving pipeline opening/closing controllers 65a, 65b, and 65c. In addition, after a refrigerant is circulated to the indoor heat exchangers 71 from the heat exchangers 71 through the opened pipeline by operating a compressor 61 for a fixed period of time, the post-operation temperatures of the pipelines 80a, 80b, and 80c connected to the heat exchangers 71 are inputted. The operation and post-operation temperatures of the pipelines 80a, 80b, and 80a thus inputted are compared with each other and the connected states of the pipelines 80a, 80b, and 80c are discriminated from the temperature changes and displayed. Therefore, the connected states of the pipelines 80a, 80b, and 80c can be checked quickly and easily and the cost of installation of a multizone air conditioner can be saved. In addition, the misoperation of the air conditioner due to the carelessness of general users can be prevented.</p> |
