Patent number: 9648788Abstract: In accordance with embodiments, a server room managing air conditioning system includes: a first coil; a second coil; and an air supply fan. The first coil adjusts returned air of a server room to a predetermined temperature value lower than a supplied air temperature target value and dehumidifies the returned air. The second coil adjusts the returned air of the server room to a predetermined temperature value higher than the supplied air temperature target value so that the supplied air temperature target value and a supplied air humidity target value can be achieved when the returned air is mixed with air adjusted by the first coil. The air supply fan mixes the returned air and supplies the mixed returned air as the supplied air to the server room.Type: GrantFiled: April 2, 2015Date of Patent: May 9, 2017Assignee: Kabushiki Kaisha ToshibaInventors: Dai Murayama, Yasuo Takagi, Yuuichi Hanada, Hideyoshi Ootani, Tomoyuki Kinoshita, Hiroshi Morimoto, Koubun Takahashi

Patent number: 9420725Abstract: A controller and indoor unit introducing outdoor air and/or return air from an air conditioning control target, and discharging introduced air to the air conditioning control target as supply air. The indoor unit includes a first space including an outdoor air introducing unit introducing outdoor air, a cooler, and a second space including a return air introducing unit introducing return air from the air conditioning control target. The controller, after determining air conditioning control on the air conditioning control target is necessary, introduces the outdoor air to the first space through the outdoor air introducing unit, subjecting such to cooling by the cooler and/or dehumidification to result in processed outdoor air, and introduces the return air to the second space through the return air introducing unit, where the processed outdoor air is mixed with the return air and supplied to the air conditioning control target as the supply air.Type: GrantFiled: November 30, 2012Date of Patent: August 16, 2016Assignee: Kabushiki Kaisha ToshibaInventors: Makoto Honda, Hiroshi Morimoto, Kazuhide Sato, Hideyoshi Ootani, Tomoyuki Kinoshita, Dai Murayama, Yasuo Takagi

Patent number: 9237680Abstract: In an embodiment, an air conditioning system for managing a server room, which has first and second spaces separated from each other, in which a server is installed between the first and second spaces, and supply air flowed into the first space is heated by heat generation of the server, and flows out as return air via the second space, includes: a cold air generation device; an air supply fan; a first differential pressure gauge; and a control device. The cold air generation device generates supply air satisfying a predetermined condition. The air supply fan flows the generated supply air into the first space. The first differential pressure gauge measures a differential pressure of a static pressure of the second space with respect to a static pressure of the first space.Type: GrantFiled: March 2, 2012Date of Patent: January 12, 2016Assignee: Kabushiki Kaisha ToshibaInventors: Dai Murayama, Yasuo Takagi, Yuuichi Hanada, Hideyoshi Ootani, Tomoyuki Kinoshita, Hiroshi Morimoto, Koubun Takahashi

Patent number: 9188356Abstract: According one embodiment, an air-conditioning system is connected to a server room, in which server racks accommodating a plurality of servers are placed between separated first and second spaces, by a return air duct and a supply air duct. In the server room, an airflow is formed so that cold air flown from under the floor into the first space is heated by heat generation of the servers and is flown out from the second space as return air. The system sets control contents for generating supply air within a previously determined supply air temperature target range and a previously determined supply air humidity target range and controls the operation of each device in the system based on the set control contents.Type: GrantFiled: August 19, 2011Date of Patent: November 17, 2015Assignee: Kabushiki Kaisha ToshibaInventors: Dai Murayama, Yasuo Takagi, Yuuichi Hanada, Hideyoshi Ootani, Tomoyuki Kinoshita, Hiroshi Morimoto, Koubun Takahashi

Patent number: 9185829Abstract: A system for a server room management includes an air-conditioning control device including: an acquisition unit; a setting unit that sets content for generating supply air at temperature, absolute humidity, and relative humidity within target range, based on outside air temperature and humidity as well as return air temperature; and a controller controlling amount of outside air, amount of return air, control amount of humidifier, control amount of cooler, and amount of air blown by blower, based on the content. If the outside air is within range greater than absolute humidity upper limit, or within range greater than enthalpy upper limit and greater than the temperature upper limit, the setting unit compares outside air and return air, and then determines, in accordance with the comparison, whether to set the content so that the cooler performs cooling by minimizing or maximizing the amount of the outside air.Type: GrantFiled: June 15, 2012Date of Patent: November 10, 2015Assignee: Kabushiki Kaisha ToshibaInventors: Dai Murayama, Yasuo Takagi, Hideyoshi Ootani, Tomoyuki Kinoshita, Yuuichi Hanada, Hiroshi Morimoto, Kobun Takahashi
