Patent number: 11920841Abstract: An air-conditioning apparatus includes a main circuit in which a compressor, a flow switching device, an indoor heat exchanger, a pressure reducing device, and a plurality of parallel heat exchangers connected in parallel with each other are connected by pipes, a bypass pipe, a flow control device provided to the bypass pipe and configured to adjust a flow rate of refrigerant flowing through the bypass pipe, an evaporating pressure sensor configured to measure an evaporating pressure of the refrigerant, and a controller. The air-conditioning apparatus is configured to operate in a normal heating operation mode and a heating-defrosting operation mode. When an operation associated with the normal heating operation mode is switched to an operation associated with the heating-defrosting operation mode, the controller adjusts an opening degree of the flow control device using the evaporating pressure in the parallel heat exchanger and a driving frequency of the compressor.Type: GrantFiled: March 25, 2019Date of Patent: March 5, 2024Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Shohei Ishimura, Soshi Ikeda, Kazuya Watanabe, Hideto Nakao, Masakazu Kondo, Yasuhide Hayamaru, Yusuke Tashiro, Masakazu Sato, Atsushi Kawashima
