Patent number: 11885517Abstract: A system includes an air conditioning device with a heat exchanger that sends conditioned air to an air conditioned space, a ventilation device that ventilates the air conditioned space, a refrigerant sensor that detects a concentration of a refrigerant in the air conditioned space, and a control unit that controls operations of the air conditioning device and ventilation device. On determination that the refrigerant concentration acquired from the refrigerant sensor exceeds a first predetermined value, the control unit sets an operation of a compressor of the air conditioning device to a stop state and sets the ventilation device to an operating state. On determination that the refrigerant concentration that has exceeded the first predetermined value becomes equal to or less than the first predetermined value, the control unit continues the stop state of the compressor and operating state of the ventilation device until a predetermined timing.Type: GrantFiled: March 7, 2022Date of Patent: January 30, 2024Assignee: DAIKIN INDUSTRIES, LTD.Inventors: Kousuke Hirai, Akiyoshi Yamamoto, Gakuto Sakai, Yoshitaka Matsugi, Tooru Fujimoto

Patent number: 11859835Abstract: A controlling unit controls a refrigerant circuit and a flow path switching mechanism to perform a first humidity control operation or a second humidity control operation. In the first humidity control operation, a bypass passage is closed, and outside air is supplied into a room through one of first and second adsorption heat exchangers, and room air is exhausted to outside through the other of the first and second adsorption heat exchangers. In the second humidity control operation, the bypass passage is opened, and the outside air is supplied into the room through one of the first and second adsorption heat exchangers and the bypass passage, and room air is exhausted to outside through the other of the first and second adsorption heat exchangers.Type: GrantFiled: May 31, 2017Date of Patent: January 2, 2024Assignee: DAIKIN INDUSTRIES, LTD.Inventors: Kousuke Hirai, Gakuto Sakai

Patent number: 11536475Abstract: Internal control devices (41A to 41D) included respectively in air conditioners (10A to 10D) in an air conditioning system (1) are communicably connected one by one correspondingly to external control devices (42A to 42D). Each of the external control devices (42A to 42D) is configured to execute command generating operation of generating an operation command to a corresponding one of the air conditioners (10A to 10D). The external control devices (42A to 42D) constitute an external control system (50). In the external control system (50), one of the external control devices (42A) functions as a master control device configured to execute the command generating operation whereas remaining ones of the external control devices (42A to 42D) other than the external control device (42A) functioning as the master control device function as sub control devices configured not to execute the command generating operation.Type: GrantFiled: December 3, 2020Date of Patent: December 27, 2022Assignee: DAIKIN INDUSTRIES, LTD.Inventors: Shougo Ohta, Masaya Nishimura, Kousuke Hirai, Takayuki Sunayama
