Abstract (en)
[origin: EP4296593A1] An air conditioning apparatus (1) includes a refrigerant circuit (150) and a controller (200). The refrigerant circuit (150) is configured to allow refrigerant to circulate through a compressor (10), a condenser (40, 20), an LEV (111), and an evaporator (20, 40). The LEV (111) has an opening degree variable from a lower limit opening degree to an upper limit opening degree. The controller (200) is configured to control the LEV (111) to alternately repeat a first opening degree (CvA) and a second opening degree (CvB) in a range of less than or equal to a quarter of the upper limit opening degree, the second opening degree (CvB) being smaller than the first opening degree (CvA).
