Description

Blowing device system for air conditioner, exhaust heat conveying device system, and air conditioning system having them

technical field

The present invention relates to an air-conditioning blowing device system for a computer room equipped with a cabinet for storing a computer and adopting an underfloor air-conditioning system, and an exhaust heat transfer device for moving hot air stagnant in the upper part of the indoor space to the suction port of the air conditioner system and an air-conditioning system having these air-conditioning blowing device systems and exhaust heat conveying device systems.

Background technique

FIG. 11 is a perspective view of a conventional server room employing an underfloor air-conditioning system as an air-conditioning system. In a large-scale server room in which many large computers and servers are installed, a double-structured floor 11 is often used for wiring 25 to server machines. In a server room having such a double-structured floor 11, a so-called underfloor air-conditioning system is often used. In this under-floor air-conditioning system, an air supply chamber 23 is formed under the floor, and cold air from the air conditioner 21 is supplied to the air supply chamber 23. The cold air is released into the indoor space 15 by using a plurality of small blowing holes 11a provided on the floor, thereby air-conditioning (cooling) the room, and at the same time, the hot air generated from the server cabinet 17 is passed The flow returns to the suction port 21a of the air conditioner 21.

In the server room adopting such an underfloor air-conditioning system, the number of wires to the server equipment led to the air supply chamber 23 increases due to the development of high-intensity systems, and the following problems may arise in some cases. That is, since the overlapping wiring narrows the flow path in the air supply chamber, the cool air from the air conditioner is cut off, and the cool air cannot be blown uniformly from the entire floor of the server room as conceived in the building design. In such a case, generally near the air conditioner 21, because cool air is blown out well through the outlet hole on the floor surface, the indoor temperature becomes low. The cold air stays and becomes high temperature.

In addition, as another problem, there is also the following problem. In recent years, due to the increase in the calorific value of server equipment, only by blowing cold air from the ground cannot sufficiently cope, and local concentration of heat or heat loss occurs in a part of the indoor area. Uneven load distribution.

Furthermore, as another problem, there is also the following problem, that is, when the hot air is discharged from the cabinet on which the server is mounted, an upward airflow is strongly blown from the top of the cabinet, and due to this airflow, the natural flow of hot air along the roof of the server room The flow is obstructed, and the action of returning to the suction port of the air conditioner cannot be performed well. Conventionally, such a problem has been dealt with by lowering the set temperature of the air conditioner or adding an air conditioner.

Furthermore, as another countermeasure, it has been proposed to suppress the short circuit in which the hot air returns directly to the server by providing an introducer that guides the hot air discharged from the server to the suction port of the air conditioner (for example, refer to Patent Document 1). . As a countermeasure against this short circuit, it has also been proposed to suppress it by installing an air curtain generating unit on the top of the cabinet (for example, refer to Patent Document 2).

In addition, as another countermeasure, such a scheme has been proposed, that is, by using ducts, the cold air in the air supply chamber is directly blown to the high temperature part of the room to reduce local concentration or uneven distribution of heat load (for example, refer to the patent document 3). In addition, as an air-conditioning system using ducts, a method has been proposed in which a chamber for distributing the cold air supplied from the air-conditioning unit to a plurality of air outlets is provided, and an electric blowout control that can change the air volume from the air outlets is provided here. The damper detects environmental information such as the temperature of the air-conditioned area, controls it, and performs extremely fine air-conditioning for each area (for example, refer to Patent Document 4).

Furthermore, as another technique, a method has been proposed in which a blower device for blowing air to the high-temperature part of the room is installed to ensure the amount of air blown to the high-temperature part of the room, thereby eliminating the need to rely on direct delivery through piping. A component such as air-conditioning can suppress the temperature rise in a predetermined indoor space.

However, in the air conditioning system proposed in Patent Document 1, since the hot air is induced by the guider that completely covers the server group, it is necessary to make the surfaces forming the exhaust ports on the server side uniform (height). , Inhale the hot air discharged from each server, and guide it to the suction port of the air conditioner. In the server room where servers of various specifications are mixed, it is difficult to install, or it is necessary to install a large-scale guide, so , there is a problem of increased equipment cost.

In addition, in the conventional air conditioning system proposed in Patent Document 2, when the exhaust heat from the server staying near the roof of the server room is induced to the suction port of the air conditioner, it is induced only by the suction force of the air conditioner. , There is a problem that the indoor temperature rises centered on the vicinity of the roof.

In addition, in the method of using ducts in Patent Document 3 to directly send the cold air in the air supply chamber to the high-temperature part of the room, the cold air can be reliably sent to the heat-generating equipment, and the local concentration or heat load distribution in the server room can be reduced. However, conversely, since piping is required for each device, there is a problem of increased equipment cost. In addition, because only by this device, the hot air from the server that stays near the roof of the server room cannot be returned to the air conditioner suction port, so there is a problem that the warm environment in the upper part of the room cannot be improved.

In addition, in the system proposed in Patent Document 4, which detects environmental information such as the temperature of the air-conditioned area, controls the amount of cold air supplied by the air-conditioning unit from a plurality of air outlets that can control the air volume, and performs air conditioning. Each area can be individually controlled, but since piping is required for each device, there is a problem of increased equipment cost. In addition, since the air-conditioning control from the under-floor air supply chamber of the under-floor air-conditioning system is performed, there is a problem that it is difficult to perform a separate damper because there are blow-out openings in the entire floor area in order to use this system. For regulation control, when the air blower that detects the static pressure signal on the outlet side or the passing wind speed, controls the rotation speed, and performs static pressure control is installed on the air conditioning unit side, the static pressure to the entire outlet increases, so it is difficult to perform each area. individual control.

Furthermore, in the last-mentioned method in which each blowing device detects the temperature and operates, there is a problem that the air-conditioning balance of the entire room is disrupted, and the temperature rises in the area where the blowing device is not installed. In some cases, or because the hot air staying near the roof of the server room is not enough to return to the air inlet of the air conditioner only by the blowing device, the warm environment in the upper part of the room cannot be improved.

The present invention was made to solve the above-mentioned problems, and its object is to propose an air-conditioning blowing device system, an exhaust heat conveying device system, and an air-conditioning system having these air-conditioning blowing device systems and exhaust heat conveying device systems. The device system does not need to lower the set temperature of the air conditioner more than necessary. In addition, it does not require equipment such as piping and piping, so that the amount of cold air blown into the indoor space can be made uniform. The trapped hot air moves toward the suction of the air conditioner.
