Description

Air Conditioned Room{AIR CONDITIONED ROOM}

The invention relates to an air conditioned room comprising at least walls defining a room, at least preferably two flat heat exchangers and an electronic unit to be cooled arranged in rows within said room.

Air-conditioned rooms are known, and a cooling device in the form of a heat exchanger is disposed within the boundary wall of the room. In this case, cold air can be supplied to the room through a heat exchanger, and the cold air flows through electronic units arranged as heat, such as computers or servers, to cool them. These heats define a so-called warm passage through which warmth is inhaled.

In order to replace the heat exchanger, cooling must be stopped, as otherwise a fluid engineering short circuit may occur during the time to replace the heat exchanger.

An object of the present invention is to improve the air-conditioned room in the above-described manner so as to ensure that the electronic units are sufficiently cooled by supplying the necessary amount of cold air to the room even during the replacement of the heat exchanger.

In order to solve the above problem, the present invention is an air-conditioned room comprising at least walls defining a room, at least one flat heat exchanger, and an electronic unit to be cooled arranged as a row in the room, wherein a passage is provided between two rows. Extending, the passage is preferably separated from the room and is fluidically connected to at least one heat exchanger, i.e. with respect to the air to be sent out, the heat exchanger being at least part of a wall of one of the walls defining the room Or connected to an opening in one of the walls, the heat exchanger and/or the opening is assigned a cover element on the room side, the cover element preventing air from flowing through the heat exchanger in the first position And in a second position suggest the air-conditioned room, which allows air to flow through the heat exchanger.

In particular, since the passage is separated from the room, it is impossible to mix hot and cold air in the room.

According to the invention, a cover element is assigned to each heat exchanger, and if replacement is to be made, the cover element covers the area of the heat exchanger to be replaced or the opening in the boundary wall assigned to the heat exchanger, so that the air to be cooled is It can only flow through at least one second or other existing heat exchanger, thereby preventing short-circuiting of air. That is, the warmth from another room can flow into the room to be cooled, bypassing the heat exchanger rather than directly.

The cover element may be, for example, a roller blind, a blind, or a corresponding closing element that does not close the flow path through the heat exchanger when the heat exchanger is to be cooled.

The blind may be a blind having an adjustable slat to allow air to pass through the heat exchanger or prevent it according to its position. These blinds can be formed to be slidable together.

If a displaceable planar element is used, it can be displaced along a particularly juxtaposed flat heat exchanger to allow the cover to the required degree. If a planar element is not used, it is positioned outside the heat exchanger, in particular in the region of the boundary wall containing the heat exchanger, in a room with no heat exchanger or no openings assigned to the heat exchanger.

In particular, the passage defined by the electronic units arranged in rows is a warm passage connected to a cavity extending on the ceiling side or on the floor side, the cavity preferably at least two heat exchangers or a wall having at least one opening It is connected to another room which is limited by. The other room may be, for example, a maintenance passage in which a control unit for operating a heat exchanger or a fan required for the delivery of air is arranged.

In order to blow out the air, at least one fan, preferably a plurality of fans, is provided, which fan(s) are in particular installed above the heat exchanger(s) in the boundary wall. However, this is not an essential feature. The at least one fan may be disposed within the second room or within the cavity.

In a refinement of the invention, the other room may be defined by two walls, each of which defines a room with electrical units to be cooled arranged in rows, each with at least two flat heat exchangers and/or allocated heat. At least one opening with an exchanger.

The present invention relates to an air conditioning apparatus in a first room having electronic units to be cooled arranged in rows, each second row defining a passage connected to an area fluidically separated from the room, the area being a first by a wall. Connected to a second room separated from the room, in which at least two flat heat exchangers are arranged or two flat heat exchangers are assigned to at least one opening in the wall, by which air is Flow into or from the first room. According to the invention each heat exchanger is assigned a cover element, which in a first position prevents the passage of air and in a second position permits a through flow.

In particular, the cover element is a roller blind, preferably a blind with adjustable slats or a slidable planar element.

The area fluidically separated from the room in which the electronic units to be cooled arranged in rows are arranged may be a ceiling cavity or a hollow floor, such as a cavity defined by a suspended ceiling.

In particular, between the ceiling cavity and the second room, at least one fan is arranged to draw air from the passage.

In particular, the invention also provides at least one of a plurality of flat heat exchangers arranged in a wall or another wall defining a room and/or assigned to at least one opening in at least one of the walls. It relates to a method for replacing one flat heat exchanger assigned to one opening, in accordance with the present invention each flat heat exchanger is assigned a cover element, and one of the heat exchangers continues to flow through the other heat exchanger. For replacement when flowing, the heat exchanger or the opening assigned to it is covered by a cover element.

Other details, advantages and features of the present invention will become apparent from the following description of the claims, the features appearing in the claims (alone and/or in combination), and the preferred embodiments appearing in the drawings.

1 is a schematic diagram of a room to be air-conditioned,
2 is a plan view of a room to be air-conditioned,
3 is a cross-sectional view of a heat exchanger with a cover and a fan.

In the drawings, rooms are schematically shown in which heat dissipating electronic units such as servers are to be cooled. Thus, the rooms are in particular computer rooms.

The electronics are placed in so-called racks, and the racks are again arranged in rows.

The corresponding computer room is indicated by reference numeral 10 in FIG. 1. Racks arranged in rows have reference numerals 12 and 14.

Cold air flows through the racks 12 and 14 from the outer faces of the racks 12 and 14 (arrows 16 and 18). Thus, racks 12 and 14 define a warm passage 20 separated from room 10. To this end, the room 10 includes, for example, a suspended ceiling for forming the cavity 22, through which the warmth (arrow 24) is transferred by the fan 26, another room, also called a maintenance passage. (28) Inhaled into the inside. The first room, the room 10, is separated from the second room 28 by a wall that is partly formed as a cooling wall. To this end, heat exchangers 30 are arranged on the wall, one of which is shown in a schematic cross-section in FIG. 1.

The heat exchanger 30 includes a filter 32 on the side opposite the room 10. The heat exchanger 30 comprises a cover 34 on the side facing the room 10, and the passage surface through the heat exchanger 30 in particular the heat exchanger 30 must be replaced, for example, or maintained for example. When not to be operated for maintenance, it can be completely covered by the cover 34.

As mentioned, since at least one, preferably a plurality of different flattened heat exchangers 30 are arranged on the wall or other wall defining the room 10, at least in the case of disassembly of the heat exchanger is fluid engineering. Short circuit will occur.

Arrangement in the wall means that the heat exchanger is integrated into the wall, for example without a housing. However, the positioning of the heat exchanger in a housing installed in a wall or closing an opening in the wall has the same effect. The heat exchanger can be placed in or on the wall.

In order to avoid this, the cover 34 assigned to the heat exchanger 30 is closed, so that air may no longer flow through the opening created when the heat exchanger 30 is removed.

The cover 34 can be, for example, a rollable roller blind.

Preferably, blinds with folding slats are used. Of course, blinds that can slide together are also used.

As a further cover there is a closing plate element which can be displaced, for example along the heat exchanger 30, ie along the face of the heat exchanger towards the room 10. In this case, a corresponding cover element can optionally be assigned to one of a number of heat exchangers. The corresponding cover element can for example be guided on a rail not shown.

Since according to the solution of the invention the heat exchanger 30 is not placed directly in the wall but extends at a certain distance to the wall, an opening in the boundary wall is assigned to the heat exchanger for the passage of cooled air.

In this case, the opening can preferably be closed or opened by a cover element on the side facing the room 10.

If the warm passage 20 is connected to the ceiling cavity 22, the solution according to the invention provides a room to be air-conditioned, in which the warmth is sucked through the hollow floor.

In addition, the present invention does not give up the case where cold air is supplied to the passage extending between the racks 12 and 14 in order to inhale warmth through the heat exchanger from the side of the room 10. Even in this case, the present invention may be applied.

In Fig. 2, a configuration in which two rooms 110 and 120 extend from a maintenance passage 128 referred to as a second room is shown. In the two rooms 110 and 210, respectively, the electronic units to be cooled are particularly preferably arranged in rows in a rack as described in connection with FIG. 1.

Corresponding columns are indicated by reference numerals 112, 114 or 152, 154 or 212, 214 or 252, 254. Even in the embodiment of FIG. 2, the rows are not directly connected to the rooms 110 and 210 and define the warm passages 120, 160, 220 and 260 connected to the second room 128 through a hollow ceiling (not shown).

Direct mixing of hot and cold air is not performed in the rooms 110 and 210 so that the warm air sucked from the warm passages 120, 160, 220 and 260 is fluidly separated from the cold air in the rooms 110 and 210.

Each warm passage (120, 160, 220, 260) is assigned one heat exchanger group (130, 131, 230, 240) each consisting of three juxtaposed flat heat exchangers in the embodiment, and the heat exchanger groups Heat exchangers of the middle group 130 are denoted by reference numerals 132, 134, and 136. On the room side, each heat exchanger 132, 134, 136 is assigned a cover, denoted 138, 140, 142. Instead of being assigned a separate cover 138, 140, 142 to each heat exchanger 132, 134, 136, a displaceable element can be used, as described in connection with FIG. If the corresponding heat exchanger is to be replaced, for example, it can optionally be positioned before one of the heat exchangers 132, 134, 136.

According to FIG. 2, the groups 130, 131, 230, and 240 may be disposed at the center of the assigned passages 120, 160, 220 and 260.

2 shows that heat exchangers 132, 134, 136 are arranged in a second room, i.e., a wall 100 or 200 defining a room 110 or 210 from a maintenance room 128, the heat exchanger They form the cooler wall region of the boundary wall 100 or 200.

3 shows a cross-sectional view of the heat exchanger 300, and the outer surface of the heat exchanger is covered by a filter 320 extending from the maintenance passage side. A cover 334 extends on the side of the heat exchanger 300 facing the room 110 or 210, and the cover can close the discharge side of the heat exchanger 300 to the required degree according to the present invention, i.e., air It is designed so that it cannot flow through, or open.

A fan 326 may be disposed on the heat exchanger 300, and the fan 326 also passes through the boundary walls 100 and 200.
