Definitions

  • the present invention relates to a climate box with a heat exchanger for temperature regulation.
  • the invention further relates to a method for operating such a climate box.
  • Air conditioning boxes with a heat exchanger for temperature control are known from the prior art. Furthermore, prior art temperature control systems are known for various applications. One application for such systems is the air conditioning of individual rooms or of complete buildings. In particular, for the air conditioning of data centers systems for temperature regulation are needed, as by the operation of computer equipment, such as server systems, a significant heat generation occurs. The heat produced by the server equipment must necessarily be dissipated from the space in which the server facilities are located in order not to exceed the maximum allowable operating temperatures for such server equipment, which is reached and exceeded within a short time without dissipating the heat produced by the servers.
  • the plant shown there comprises an air conditioner, which comprises a coolant circuit, whereby an indirect cooling by means of the coolant of the building or individual rooms is made possible.
  • air conditioner which comprises a coolant circuit
  • Such cooling is particularly advantageous in that the permissible range of relative humidity and the desired temperature can be maintained very well.
  • the cooling of the system shown is done depending on the outside temperature either as indirect free cooling in winter, as active cooling in summer and as indirect free in combination with active cooling in the transitional period.
  • Object of the present invention is therefore to provide a Klimabox with heat exchanger, which causes no higher energy costs even when the heat exchanger is switched off and avoids air-side pressure losses as far as possible. It is a further object of the invention to provide a temperature control system and method for operating a temperature control system.
  • a Klimabox for temperature control by at least one air flow is conductive and containing at least one heat exchanger, characterized in that the heat exchanger is movably disposed in the Klimabox and is movable about a pivot point between at least one operating position and a rest position.
  • the climate box according to the invention preferably has a heat exchanger which is movable between exactly one operating position and a rest position.
  • the operating position is understood to be a position of the climatic box in which the air entering the climate box is passed through the heat exchanger and the heat exchanger is in operation.
  • a position of the heat exchanger in the Klimabox understood, in which the heat exchanger is located outside the air flow in the air conditioner and is not in operation.
  • the heat exchanger is preferably movable between exactly one operating position and exactly one rest position.
  • the heat exchanger In the rest position, the heat exchanger is preferably arranged perpendicular to the bottom of the Klimabox and parallel to the longer side wall of the Klimabox less preferred are rest positions in which the heat exchanger is arranged obliquely in the Klimabox, i. with an angle to the ground that is not rectangular.
  • the maximum height of the heat exchanger in the rest position preferably corresponds to the height of the Klimabox. This ensures that a particularly good utilization of the existing surface for the temperature, in particular the cooling is given.
  • embodiments are also conceivable in which the heat exchanger has smaller dimensions.
  • the heat exchanger is preferably arranged in the Klimabox according to the invention in the operating state along the diagonal of the Klimabox between two opposite corners.
  • the heat exchanger is designed, for example, as an evaporator or as a cooler.
  • the control and regulation of the Klimabox for example, by appropriate software.
  • the climate box according to the invention has the advantage over conventional air conditioning boxes that the air-side pressure losses compared to conventional air conditioning boxes can be reduced.
  • the heat exchanger is, when it is not in operation, folded out of the air flow, so that this pressure losses, which otherwise arise by flowing through the switched-off heat exchanger, can be reduced. As a result, the energy costs for operation can be significantly reduced.
  • a maintenance of the advantageous small dimensions is possible, since it is not necessary to lead the air with the heat exchanger switched off via a bypass in order to avoid pressure losses.
  • the Klimabox can be operated in different operating conditions, for example, at temperatures of the incoming air, also called outside air, which are above a temperature T 1 .
  • T 1 temperatures of the incoming air
  • T 2 active cooling by means of the heat exchanger could take place in the operating position, while in the region above T 1 and below T 2, only a mixed operation of active and direct cooling could take place, which in turn could reduce energy costs.
  • Below T 1 direct free cooling is possible ie the heat exchanger is switched off and in the rest position, so that the energy requirement can be significantly reduced.
  • At least one fan device could be provided.
  • This fan device could be arranged outside the space to be cooled, for example outdoors to improve the removal of the warm air. Especially at outside temperatures above 17 ° C, such additional removal of heat could be done by the fan device.
  • the climate boxes according to the invention are used for example in plants for temperature regulation of data centers or server systems.
  • the three different operating states already explained above are run through.
  • the entire system is operated in the active cooling mode.
  • the heat exchanger is arranged in the operating position, wherein all air flows through the heat exchanger and is cooled there.
  • a mixed operation of active cooling and direct cooling ie only a portion of the total air flow is passed through the heat exchanger, another part of the air flow is mixed outside the Klimabox the cooled air stream.
  • this airflow must be outside air or circulating air from the entire system.
  • the third mode of direct free cooling the system is cooled exclusively with outside air. In this operating state, the heat exchanger is in rest position and the air box can be flowed through unhindered by the air flow.
  • the mixing box according to the invention can be used for example as part of an air conditioner or as an air conditioner.
  • the Klimabox is used for cooling data centers, servers, computers or server systems as well as server racks. It is also possible to combine the inventive Klimabox with a mixing box, which allows a further optimization of the operating conditions.
  • Such a mixing box knows, for example, various flaps, namely an outside air flap, a recirculation flap and a mixed air flap, which allows a targeted mixture of different tempered air streams.
  • Such a mixing box is described in the European patent application 09 005 824.9 , which is hereby incorporated by reference. The combination of a Klimabox with this mixing box for a direct free cooling is thus also part of the application.
  • FIG. 1a shows an embodiment of the invention Klimabox 1, with a heat exchanger 9 in the operating position.
  • the inflowing from the top of the climate box Air in Fig. 1 b is indicated by arrows, is accordingly transported completely through the heat exchanger 9 to the bottom 8 of the Klimabox.
  • the heat exchanger 9 is connected at its lower end with a hinge 2, which serves as a fulcrum.
  • the pivot point can be arranged in other embodiments, not shown, elsewhere along the heat exchanger.
  • the heat exchanger 9 is limited by an upper frame 2, against which it leans. Parallel to the heat exchanger 9 extends a lateral seal 5 which is fixed to the front side wall, not shown.
  • an electric box 7 is arranged, which serves for controlling and regulating the Klimabox.
  • Fig. 1 c shows the perspective view. It can be seen that the heat exchanger 9 extends over the entire width of the Klimabox and approximately diagonally connects the two opposite corners. In the lower part of the heat exchanger 9 is located on the sealing groove 6.
  • Fig. 2a is the Klimabox shown with heat exchanger 9 at rest.
  • the heat exchanger 9 is arranged parallel to the side wall 4 and stands on the rail 3, which is located in the bottom of the Klimabox. Accordingly, the air flows as in Fig. 2b from the top of the air box to the bottom 8 of the air box without flowing through the heat exchanger.
  • the heat exchanger 9 extends almost from the bottom 8 to the top of the Klimabox. 1
  • lateral seal 5 is arranged only on the two short side walls and does not extend over the entire width, as well as the heat exchanger 9.
