Blowing out device system for air conditioner, heat removal transmission device system and air conditioning system with the same

Abstract

The invention provides a blowing device system for air-conditioner, which is able to equalize the cooling air amount blown to the indoor space. In the invention, the blowing device system for air-conditioner includes an air-conditioner (21), an air-supply chamber (23), a plurality of blowing-out devices (30), an air flow measurement part and a blowing-out control part; the air-conditioner (21) inhales the air from an inhalation hole (21a) and blows out the cooling air from a blowing-out hole; the air-supply chamber (23) is formed under the ground and ventilates the air-conditioner (21), in the meantime, the cooling air is blown out to the indoor space (15) through a plurality of blowing-out holes (11a) formed on the floor; the plurality of blowing-out devices (30) inhale the cooling air in the air-supply chamber (23) and blows out to the indoor space (15); the air flow measurement part measures static pressure or wind speed of the cooling air within the air-supply chamber (23); the blowing-out control part, in accordance with the output of the air flow measurement part, enables the blowing-out devices near a stated position within the air-supply chamber to operate when the static pressure or wind speed of the cooling air at the stated position within the air-supply chamber is less than or equal to the limit value, so that the cooling air within the air-supply chamber is blown to the indoor space.

Description

technical field [0001] The present invention relates to an air-conditioning blower system for an electronic computer room in which a cabinet for accommodating an electronic computer is installed, and an under-floor air-conditioning system is adopted, and a heat exhaust conveying device that moves the hot air accumulated in the upper part of the indoor space to the suction port of the air conditioner. A system and an air-conditioning system having these air-conditioning blowing device systems and exhaust heat conveying device systems. Background technique [0002] FIG. 11 is a perspective view of a conventional server room using an under-floor air-conditioning system as an air-conditioning system. In a large-scale server room or the like in which a large number of large computers and servers are installed, the double-structure floor 11 is often used in order to perform the wiring 25 to the server equipment. In a server room having such a double-structured floor 11, a so-call...

Problems solved by technology

[0013] 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

[0014] 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 around the roof

[0015] 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. Unevenness, but on the contrary, there is a problem that the cost of equipment increases because piping is required for each machine

In addition, because this device alone cannot return the hot air from the servers staying near the roof of the server room to the air conditioner suction port, there is a problem that the warm environment in the upper part of the room cannot be improved.

[0016] 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. It is possible to control each area individually, but there is a problem that the cost of equipment increases because piping is required for each machine

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. separate control

[0017] 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 stagnant near the roof of the server room is not enough to return to the suction port of the air conditioner only by the blowing device, the warm environment in the upper part of the room cannot be improved.
