Patent number: 11428422Abstract: When an outdoor air handler performs a heating humidifying operation and an air conditioner performs a cooling operation, a control device adjusts at least one of a to-be-supplied air temperature of the outdoor air handler, a to-be-supplied air flow rate of the outdoor air handler, a to-be-supplied water flow rate of the outdoor air handler, and a cooling temperature that is a temperature at an air heat exchanger of the air conditioner. The control device adjusts the to-be-supplied air temperature and the cooling temperature on the basis of dehumidification information, operation information, temperature information, and humidity information. The operation information is information regarding an operating state of the air conditioner.Type: GrantFiled: December 17, 2021Date of Patent: August 30, 2022Assignee: DAIKIN INDUSTRIES, LTD.Inventors: Yasunori Okamoto, Naotoshi Fujita, Kouji Tatsumi, Masaaki Kawagishi, Shinya Umase

Patent number: 11402118Abstract: It is an object of the present disclosure to collectively control an outdoor air handler and an air conditioner optimally. An air-conditioning system (100) includes an outdoor air handler (10) configured to adjust a temperature and a humidity of taken-in outdoor air and supply the air to a target space (SP1, SP2), an air conditioner (20) configured to adjust a temperature of air in the target space (SP1, SP2), and a control unit (30). The control unit (30) is configured to, in a case where one of the outdoor air handler (10) and the air conditioner (20) is in a non-temperature adjusting state in which the temperature of the air is not adjusted, change an air conditioning capacity of the other one of the outdoor air handler (10) and the air conditioner (20) compared with a case where the outdoor air handler (10) and the air conditioner (20) are in a temperature adjusting state in which the temperature of the air is adjusted.Type: GrantFiled: November 29, 2021Date of Patent: August 2, 2022Assignee: DAIKIN INDUSTRIES, LTD.Inventors: Yasunori Okamoto, Naotoshi Fujita, Kouji Tatsumi, Masaaki Kawagishi, Shinya Umase

Patent number: 10989429Abstract: Provided is an air conditioning system that achieves energy conservation and comfortableness. In the air conditioning system (100), an outdoor-air conditioner (10) sucks outdoor-air (OA) and supplies the outdoor-air as supply air (SA) from an air handling unit (30). An indoor-air conditioner (50) cools or heats indoor-air (IA) that is an air inside a target space (SP) by using an indoor unit (70) and supplies the air to the target space (SP). A general control unit (90) controls performs cooperative load control in which an operating capacity of the outdoor-air conditioner (10) and an operating capacity of the indoor-air conditioner (50) are controlled in cooperation in accordance with a status of the outdoor-air (OA), a status of the indoor-air (IA), an operation status of the outdoor-air conditioner (10), and/or an operation status of the indoor-air conditioner (50).Type: GrantFiled: March 30, 2018Date of Patent: April 27, 2021Assignee: Daikin Industries, Ltd.Inventors: Yasunori Okamoto, Naotoshi Fujita, Kouji Tatsumi, Masaaki Kawagishi
