ABSTRACT:
Disclosed are a device and a method for vacuumizing an air conditioner having multiple compressors and multiple condensers respectively connected with the compressors by multiple refrigerant pipes. The refrigerant pipes are interconnected by a connection pipe. An inlet of one of the compressors and the connection pipe are connected to a manifold. A vacuum pump is connected to the manifold. The inlets of compressors other than the compressor connected to the manifold and an outlet of the condensers are closed. Thus, the compressors and the condensers form a closed circuit. When the vacuum pump operates, the inner space of the closed circuit is vacuumized. Since many compressors and condensers can be vacuumized using a single vacuum pump, the cost of manufacturing a vacuumizing device is reduced.
