Patent number: 9441862Abstract: An air-conditioning apparatus in which a primary-side refrigerant in a two-phase gas-liquid state that has flowed into each of intermediate heat exchangers absorbs heat from a secondary-side refrigerant flowing in counterflow to the primary-side refrigerant, and evaporates and turns into a low-temperature, low-pressure gas state. The air-conditioning apparatus ensures high heat exchange efficiency even when a direction of a heat source-side refrigerant (secondary-side refrigerant) flowing through an intermediate heat exchanger changes, and enables an appropriate operation in any operation mode.Type: GrantFiled: January 23, 2012Date of Patent: September 13, 2016Assignee: Mitsubishi Electric CorporationInventors: Asako Tamura, Naofumi Takenaka, Shinichi Wakamoto, Susumu Yoshimura, Koji Yamashita
