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.

A composition that includes a high-valent compound of copper, silver or indium; a linear, branched or cyclic Calcohol; and a Group VIII metal catalyst forms a metal film of copper, silver or indium on a substrate when the composition is coated on the substrate and heated to reduce the high-valent compound. The composition may alternatively include metal particles of silver, copper or indium in which the surface layer of the particle includes a high-valent compound of copper, silver or indium. A metal film of copper, silver or indium may also be formed on a substrate by coating a substrate with the composition including the metal particles, and heating to reduce the high-valent compound in the same manner as above.

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.

Air conditioning system and air conditioning control method for server room

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.

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.

Server room managing air conditioning system and air conditioning control method

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.

Air conditioning system and method for managing server room

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.

An embodiment includes a first space, a second space, a first damper, a second damper, and a third damper. The first space is connected to a cold space, having cold air reside therein to send to the cold space. The second space has return air reside therein, as it is discharged from a hot space. The first damper has an opening adjusted under control of a controller to take in outdoor air to the first space, and is operable to have an open state in an emergency with a server being supplied with power. The second damper has an opening adjusted under control of the controller to discharge return air in the second space, outside thereof, and is operable to have an open state in the emergency. The third damper has an opening adjusted under control of the controller to recirculate return air in the second space to the first space.

Air conditioning apparatus and air conditioning system

Some embodiment includes an air conditioner, an air blower, a sensor, and a controller. The air conditioner works for supply to cold spaces. The air blower produces streams of air in and between a server room and an air conditioning system. The sensor takes a measure of current or power as consumption at servers. The controller operates on the measure at the sensor, to control the air blower.
