High-low pressure passage switching device in heating-cooling apparatus

摘要: A high-low pressure passage switching device in a heating-cooling apparatus comprises hollow tube; high gas inlet port formed wall of the tube and connected to outlet compressor; first port/low one end heat exchanger; second output other flow switch disposed within capable rotating about fixed axis. The is adapted supply introduced from selectively thereby passage. When supplied exchanger through selected port, low into so that interior normally filled with gas. compressor guided port.
