Definitions

  • the invention relates to an air conditioning device, intended for a plurality of premises, distributed along a service corridor, at least one wall of which constitutes partitions for these premises, and comprising a plurality of air conditioning batteries, each assigned to a room comprising a box where, under the impulse of a motor-fan group, air circulates between a return outlet and a blowing outlet, passing through a filter in series, an exchanger connected to a general circuit coolant and a heating coil.
  • a first device consists in installing a general air conditioning unit, with refrigeration and heating groups and exchangers equipped with motor-fan groups, filters, to treat the air which is then distributed to the various premises by a network.
  • supply air ducts coupled with a network of return ducts to bring the air from the premises to the air conditioning unit.
  • This type of device generally requires having been provided for the construction of the building, the ducts are bulky, and the modulation of the air conditioning in each room is difficult without unbalancing the whole.
  • Another type of device easier to install in an already constructed building, consists in installing, in each room to be air conditioned, an air conditioning battery comprising a motor-fan group, a filter, an exchanger supplied with coolant, and a battery of heating, for example an electrical resistance, and for the whole building a refrigeration plant from where a heat transfer liquid is refrigerated and distributed by a network of pipes to each battery exchanger.
  • the coolant distribution and return pipes are much less bulky than air conditioning ducts, the energy transported per unit of volume being more than 3,000 times higher for water than for air.
  • the coolant pipes follow the service corridors, often above a false ceiling and, in line with each room to be refrigerated, there are two taps on the supply pipes and return, which enter the room to service the air conditioning battery.
  • the air conditioning battery generally comprises a trunk where, under the impulse of the motor-fan group, the air circulates between a return outlet and a blower outlet, passing in series through the filter, the exchanger suitably connected to the circuit general coolant and heating coil.
  • the return and blowing outlets are associated with ducts which open into the room in carefully chosen locations. It is common for the air conditioning battery and / or ducts to be hidden above a false ceiling.
  • Each air conditioning battery has thermostatic control members, which act on the flow of coolant, the flow of air in the battery and the heating of the heating coil, or on some of these parameters. It is therefore possible, without unbalancing the entire device, to modulate the air conditioning of each of the premises.
  • the invention aims to improve air conditioning devices with individual batteries, by overcoming their objectionable aspects.
  • the invention provides an air conditioning device, intended for a plurality of premises distributed along a service corridor of which at least one wall constitutes a partition for the premises, and comprising a plurality of air conditioning batteries, each assigned to a room and comprising a box where, under the impulse of a motor-fan group, air circulates from a return outlet to a blowing outlet, passing through a filter, an exchanger connected to a general circuit of coolant, and a heating coil, characterized in that the return and blowing outlets are located in the same face of the trunk and this is mounted in the service corridor with the face where the outlets are located applied to the partition, where passages are made corresponding respectively to the return and blowing outlets.
  • the air conditioning battery box By placing the air conditioning battery box in the service corridor, the annoying source of noise is transferred outside the room, as well as the source of condensation and possible refrigerant leakage. In addition, the maintenance of the air conditioning battery no longer requires entering the room at the risk of disturbing the occupants. Finally, the general coolant circuit is simplified, by shortening, for each battery, the branches from the pipes placed in the service corridor.
  • the sides of the trunk generally rectangular in shape, will be fitted with thermal and sound insulation.
  • an air conditioning battery arranged in a trunk 4 is mounted on a partition 1 of a service corridor 2, to serve a room 3, such as a hotel room or a office.
  • a partition 1 In this partition 1 is made a rectangular opening 1a, near the ceiling and extended parallel to it.
  • the trunk 4 being generally parallelepiped, it has on one side two superimposed mouths 10 and 17 which fit into the opening 1a.
  • the upper mouth 10 forms the return mouth, and the lower mouth 17 the blowing mouth.
  • the horizontal separation between the vents is located at a false ceiling 3n, in which will be practiced, at appropriate locations, air intake vents from room 3 (not shown) while the blowing outlet delivers air conditioning to the room, here directly.
  • the return mouth extends, inside the trunk 4 by a sheath 11, limited to its lower part by a horizontal partition 11a which extends from the front face 103 to the rear face 101 of the trunk 4.
  • the partition 11a stops before the posterior face 101, to form an opening where a generally flat and horizontal filter 12 is placed.
  • a motor-fan group Below the filter 12 is arranged a motor-fan group; in this group, a central motor 13a drives two rotors of centrifugal fans 13, the scrolls of which open into a vertical partition 13b, in the direction of the blowing mouth 17.
  • the vertical partition 13b, the rear face 101 of the trunk 4, the filter 12 and a lower face 102 of the box 4 confines a box with which the suction openings of the fans 13 are in communication.
  • an exchanger or refrigeration coil 14 In front of the partition 13b is arranged an exchanger or refrigeration coil 14, with inlet pipes 14a and outlet 14b of coolant, respectively connected to supply pipes 21 and return 22, insulated, longitudinally arranged in lane 2 and which, with a refrigeration unit (not shown, of course), refrigerant circuits.
  • the refrigeration battery 14 is followed by a heating battery constituted by an electric heating resistor 15.
  • a collecting tank 16 for the condensed water vapor is disposed below the exchanger or the cooling coil 14 .
  • This tank 16 comprises at the end an outlet 16a, which communicates with a tank 5, fixed outside the trunk 4, on a lateral face 105 of the latter.
  • This reservoir has an overflow which opens into a general evacuation pipe 23, parallel to the pipes 21 and 22 of coolant. Of course this pipe 23 is connected, from place to place, to the downspouts for discharging waste water.
  • the fans 13 in operation place under vacuum the box formed by the filter 12, the partition 13b, the rear wall 101 and bottom 102, as well as the side walls 104 and 105 of the box. Air is drawn in accordingly through the filter 12 in the sheath 11 and, via the return outlet 10, in the room 3, through the return orifices of the false ceiling 3A. The fans 13 discharge the air thus sucked through the exchanger 14, where it cools and abandons the excess water vapor, then through the resistor 15 where it heats up, before being returned to the room 3 through the air outlet 17.
  • the air conditioning battery comprises regulating members, thermostatic control, to modulate the circulation of coolant in the battery 14, the heating of the resistor 15, and, moreover, the speed at which the motor 13a. drives the fans 13.
  • the air conditioning battery is classic in principle, and by the organs that constitute it. But, while conventionally we have the different elements in line to separate the return air intake and the supply air, and make the installation inside the room to be conditioned efficient, here we fold the alignment of the elements to attach the return air vents and blowing through the partition 1.
  • the trunk 4 was substantially parallelepipedic, with an anterior face 103, a posterior face 101, an upper face 100, a lower face 102, and two lateral faces 104 and 105. All these faces are filled with layers of foam. rigid, about 10 mm thick, forming thermal and sound insulation, with the exception, for the front face 103, of the location of the return 10 and blowing 17 outlets. Thanks to this arrangement, and by l use of fans extended along the axis of rotation of the rotor, the noise level transmitted outside the trunk 4 in the corridor 2 is low, while the partition 1 essentially prevents the transmission of noise inside the local 3.
  • the filter 12 is mounted in a drawer in the rear wall 101, with a face 120 on outside the wall 101. Also the assembly of the refrigeration exchanger 14, the resistor 15 and the tank 16 can be extracted from the trunk by a hatch formed in the lower wall 102.
  • FIG. 3 represents the arrangement of air conditioning batteries 40, 41, 42, 43, assigned respectively to premises 30, 31, 32, 33, distributed on either side of a service corridor 2, limited by partitions 1 and 1 ′ which separate it respectively from the premises with even and odd references.
  • air conditioning batteries which are connected to the supply lines 21 and return 22 of the coolant, by short branches.
  • auxiliary tanks 50, 51, 52, 53 for collecting condensate from the respective batteries 40, 41, 42, 43. These tanks 50, 51, 52, 53 are connected as short as possible to the drain pipe 23 condensates.
  • the invention is not limited to the examples described, but embraces all of the variant embodiments thereof, within the framework defined by the claims.
  • the location of the fan in the air circulation is arbitrary.
  • the heating coil has been described in the form of an electrical resistance. But it goes without saying that this heating coil can be an exchanger supplied by a hot heat-transfer liquid, like a central heating radiator. Also when heating is provided by passing a heat transfer liquid through an exchanger, it is possible to confuse the cold battery and the hot battery into a single exchanger, which will be supplied, depending on the circumstances, with coolant or hot coolant.
  • the invention is also applicable to buildings where the premises are not regularly distributed on either side of a service corridor. It suffices that this corridor serves a plurality of premises to be air conditioned.
