    专利说明:

    The invention relates to a refrigerating installation of a building.
    It relates more specifically to a known refrigeration installation of a building as shown in FIG. 1. This type of installation comprises an interior module 1 at building B, consisting of a refrigerating machine 1, and a module 2 outside the building, these two modules being connected to each other by refrigerant pipes 3A, 3B. An installation of this type is a heat pump that recovers calories from air, soil or water through a heat exchanger contained in the outdoor unit 2. The calories are transmitted by the refrigerant to a heat exchanger contained in the indoor unit 1, which heats water transmitted by a hydraulic connection 5A to a hydraulic transmitter, for example a heating floor 4A or a radiator 4B, in a closed circuit, the cooled water being returned to the inner module 1 by a hydraulic link 5B back. Inside the building, the refrigerant lines 3A, 3B are connected by means of connections to the inlet and outlet pipes of the exchanger. These connections are arranged outside the internal module.
    R410A is currently used as a refrigerant and is a refrigerant replacing R22 according to the Montreal protocol for positive cold applications. It is composed of 50% R32 (difluoromethane) and 50% R125 (pentafluoroethane).
    For environmental reasons, other refrigerants with a lower GWP (acronym for "Global Warming Power") are considered, such as pure R32, propane or a hydrofluoroolefin.
    However these other refrigerants may be more flammable and / or more toxic than R410A and it is important to consider the risk of these gases inside a building and manage the risk of leakage of these gases. The invention solves this problem by providing a sealed barrier between the indoor refrigerating machine and the building, can be set up by the installer and preventing the presence of refrigerant in the home in case of leakage.
    To do this, the invention proposes a refrigeration installation of a building comprising at least one heat exchanger included in a refrigerating machine inside the building and traversed by a refrigerant, characterized in that it comprises a sealed box containing said refrigerant machine. and having a sealed duct leading to the outside of the building.
    Although particularly intended for a heat pump type of refrigerating machine as described above, the invention applies to any refrigeration plant comprising at least one heat exchanger included in a refrigerating machine inside the building and traversed by a refrigerant as per example an air conditioning system, a water heater or a thermodynamic transmitter such as a radiator. This installation can be two separate modules as previously described with reference to Figure 1 or be monobloc, the two refrigerant modules being assembled in a single interior block building.
    The sealed duct is then preferably arranged taking into account the density of the refrigerant, for example in the lower part of the box, to ensure better evacuation of the fluid.
    According to a preferred embodiment, the installation of which said heat exchanger is connected to a supply and a discharge of a refrigerant by refrigerant pipes connected by means of connections to the inlet and outlet ducts of said exchanger, is characterized in that said watertight box also contains said connectors and is passed through tightly by said refrigerant lines.
    Fluid leaks are most often located on components of the refrigerating machine or on the pipe connections and, thanks to the invention, these leaks are confined in the watertight container and discharged through the sealed conduit to the outside of the machine. building, without risk of introduction inside this building.
    Preferably, said supply and said evacuation of the refrigerant is the outlet and the inlet of a second refrigeration module outside the building.
    Advantageously, said sealed box or said sealed conduit contains a presence detector of said refrigerant.
    The confinement of the refrigerant in the box also facilitates the detection of a leak, for example by density difference detection.
    The sealed conduit disposed according to the density of the fluid, for example in the lower part of the box, ensures rapid detection.
    Advantageously, said box is also traversed sealingly by hydraulic and / or electrical connections of the refrigerating machine.
    Said box may include a fan.
    According to one embodiment, said box also contains a boiler combined with said refrigerating machine, said sealed duct containing a second flue of the boiler and said box being penetrated in a sealed manner by hydraulic, fuel and electrical connections. Boiler.
    Said boiler may comprise a fan equipped with an air intake disposed in said box.
    Preferably, said box is penetrated in a sealed manner by said refrigerant pipes and / or said hydraulic and / or electrical connections by means of bulkhead-type parts or glands. The invention is described below in more detail with the aid of figures representing only preferred embodiments of the invention.

    Figure 6 is a longitudinal sectional view of detail of the invention according to a first embodiment.
    Figures 7A and 7B are perspective views and in longitudinal section of detail of the invention according to a second embodiment.
    As illustrated in FIGS. 2 to 5, a refrigerating installation of a building B comprises a heat exchanger included in an internal refrigerating machine 1 at the building and connected to a supply and a discharge of a refrigerant via refrigerant pipes 3A. 3B connected by means of connectors 11A, 11B to the inlet and outlet ducts of the exchanger.
    According to the invention, the installation comprises a sealed box 10 containing the refrigerating machine 1 and these connections 11 A, 11 B, sealed through the refrigerating pipes 10A, 10B and electric not shown and having a sealed conduit 12 opening to outside the building. This duct 12 ensures the evacuation of the fluid to the outside of the building in case of leakage and avoids the creation of an overpressure in the box 10.
    This watertight case 10 is preferably designed according to the principles of combustion boiler box, with an assembly of panels made of sheet metal, plastic or alloy, with seals or foams.
    Referring to Figure 1, the supply and discharge of the refrigerant is preferably the outlet and the inlet of a second heat exchanger contained in a module 2 outside the building. And the hydraulic connections 5A, 5B connecting the refrigerating machine 1 to a heating floor 4A or a radiator 4B also pass in a sealed manner the housing 10.
    As illustrated in Figure 3, the sealed conduit 12 is arranged taking into account the density of the refrigerant, to ensure better evacuation of the fluid. Here the density of the refrigerant is supposed to be greater than that of the air and the sealed duct 12 is arranged in the lower part of the box 10.
    The sealed conduit 12 is equipped with a detector 13 for the presence of the refrigerant, for example by density difference detection.
    The refrigerating machine 1 may be provided with a ventilator improving the evacuation of refrigerant leaks.
    According to the embodiments shown in Figures 4 and 5, the box 10 also contains a boiler 20 combined with the refrigerating machine 1 which is a heat pump.
    In this case, the sealed duct 12 contains a second duct 12 'for evacuating the flue gases from the boiler which is here internal and concentric with the sealed duct 12 and the casing 10 is penetrated in a sealed manner by hydraulic and fuel connections 5Ά, 5 B, 5'C of the boiler 20.
    The boiler 20 comprises a fan 21 which can be equipped with an air intake disposed in the box 10, taking into account the difference in density of the refrigerant and air. As shown in Figure 5, this air intake 22 may be in the lower part of the box 10, if the density of the refrigerant is greater than that of air.
    Figures 6 and 7 show in more detail examples of sealed arrangements ensuring the sealed passage of the refrigerant pipes and / or hydraulic and / or electrical connections.
    Figure 6 shows elastomeric parts in two pieces or slits, clamped around the pipes and tubular connection.
    FIGS. 7A and 7B show membrane pass-through elastomeric parts 30 'conventionally used in the field of boilers.
