<p><P>PROBLEM TO BE SOLVED: To provide an air-conditioning apparatus that suppresses the occurrence of pulsation noise. <P>SOLUTION: The air-conditioning apparatus at least includes: a refrigerating cycle having a compressor 1, an indoor side heat exchanger 3, an outdoor side heat exchanger 4, and a variable electric expansion valve 5; a saturation temperature detection means 8 (9) that detects a saturation temperature of a cooling medium 10; and a discharge temperature detecting means that detects a temperature of the cooling medium discharged from the compressor 1. The air-conditioning apparatus calculates the degree of superheat of the cooling medium that is absorbed into based on the difference between the saturation temperature that is detected by the saturation temperature detection means and the discharge temperature that is detected by the discharge temperature detecting means, and increases an operation frequency of the compressor when the calculated degree of the superheat of the cooling medium is lower than a certain threshold. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
