20110306288 | AIR CONDITIONING SYSTEM AND METHOD FOR MANAGING SERVER ROOM - 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. | 12-15-2011 |
20120164930 | SERVER ROOM MANAGING AIR CONDITIONING SYSTEM AND AIR CONDITIONING CONTROL METHOD - 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. | 06-28-2012 |
20120179596 | POWER RESERVE MARGIN TRADING SYSTEM AND POWER RESERVE MARGIN TRADING METHOD - A power reserve margin trading system according to one embodiment includes a reserve margin trading unit, a determination unit, and a trading consideration distribution unit. The reserve margin trading unit acquires a power reducible amount of a customer, trades the reducible amount as a reserve margin for demand adjustment, and acquires a consideration. The determination unit determines a rank of each customer by giving a higher rank to a customer having a smaller difference between a predicted power demand amount and a power consumption amount. The trading consideration distribution unit distributes a consideration to customers so that a portion of the consideration to be distributed varies depending on whether or not the power reduction request is transmitted. | 07-12-2012 |
20120234527 | SERVER ROOM MANAGING AIR CONDITIONING SYSTEM - 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. | 09-20-2012 |
20130005235 | AIR CONDITIONING SYSTEM AND AIR CONDITIONING CONTROL METHOD FOR SERVER ROOM - According to the embodiment, the air conditioning system for a server changes air conditioning control target values within a certain range when outside air and return air both have higher specific enthalpy than the target state and hence the mixed air of the outside air and the return air cannot be adjusted to air in the target state. | 01-03-2013 |
20130066585 | PREDICTED MEAN VOTE ESTIMATING DEVICE AND COMPUTER PROGRAM PRODUCT - According to one embodiment, a PMV estimating device calculates a PMV value from an average room radiation temperature, room temperature, room humidity, room air velocity, an amount of cloth worn by a person in the room, and an amount of activity of the person in the room. The PMV estimating device includes: indoor solar radiation calculator; solar radiated article temperature estimator; and average radiation temperature estimator. The indoor solar radiation calculator calculates an amount of solar radiation entered into the room. The solar radiated article temperature estimator estimates a temperature of a solar radiated article receiving the solar radiation entered into the room, by using the amount of solar radiation entered into the room calculated by the indoor solar radiation calculator. The average radiation temperature estimator estimates the average room radiation temperature by using the temperature of the solar radiated article estimated by the solar radiated article temperature estimator. | 03-14-2013 |
