The water cooler 98 comprises a water supply 102, as well as a water drain 104. The water supply is connected to a distributor 106, from which extend the pipelines 108, 110, 112, which span a surface parallel or substantially parallel to a bottom surface. from a housing of the heat exchanger 14. The pipelines are diverted on a front side 114 of the heat exchanger opposite the distributor 106 through tube arches 116, 118, 120, then re-routed on a front side 122 by means of a tube arch 124, 126, 128 and subsequently back by means of tube arches 130, 132, 134 a distributor 136 connected to the water outlet 104.

    The invention is distinguished by the fact that the evaporator 32, 100 together with the water cooler 46, 98 are completely embedded in the storage medium 52 as cast.
    The storage medium comprises a paraffin mixture comprising a mixture of saturated n-paraffin hydrocarbons from petroleum. The mixture has a melting range of 4 ° C to 7 ° C, typically 6 ° C, and a solidification range of 6 ° C to 2 ° C, typically 6 ° C. The density (solid) at -15 ° C is 0.88 kg / l and the density (liquid) at + 15 ° C is 0.77 kg / l. The paraffin mixture has a heat conductivity coefficient of approximately 0.2 W / mk.
    The paraffin-based storage medium 52 is a special mixture with the property of making very much energy available for cooling. Depending on the mixture, where the melting point is adjustable, the energy can be made available at different temperatures.
    The heat exchanger 14 comprises a holder 176 with bottom 178 and side walls 180, 182, 184, 186. The bottom 178 and the side walls 180 to 186 are preferably insulated on the inside with insulating plates 188. The heat exchanger package 54, 96 is provided in the holder 176.
    For the production of the heat exchanger 14, the paraffin mixture liquid from approximately 10 ° C to 12 ° C is poured into the container 176 preferably made of stainless steel, wherein both the evaporator 32, 100 and the water cooler 46, 100 - until the inlet and outlet 102, 104 or 138, 140 - are completely cast.
    During use, the storage medium 52 is then cooled and solidified at a temperature in the range of 2 ° C to 4 ° C through the coolant circuit 12. During maintenance operation, i.e., when, for example, the power supply for the cooling circuit 12 has failed, the energy released by the melt enthalpy is used for cooling the water circuit 16. This process starts at a temperature of the storage medium of approximately 10 ° C.
    In the exemplary embodiment according to FIG. 1, the coolant circuit 12 is provided with a power that is at least twice as large as the power required for cooling the heat exchanger 14; therefore, the refrigerant circuit 12 cools both the storage medium 52 and the water circuit 16, i.e., the water for cooling the diver high pressure chamber.
    The in FIG. The climate device illustrated in Figure 1 is characterized in that, for example, in the event of a power supply failure for the coolant circuit 12, the cooling energy for cooling the water of the secondary circuit 16 is recovered from the heat exchanger 14, which is currently operating as a storage buffer. If a diver is in the diver's high-pressure chamber during the power supply failure, the inside temperature can further be set to a constant value of 29 ° C, independent of the outside temperature. The pump 42 and the aeration 40 are operated in this case by an emergency power unit. In addition, it is possible to transfer the diver's high-pressure chamber together with the cooling water circuit 16 and the storage buffer 14, for example, from a ship to a land transport means, with which the diver's high-pressure chamber can be transported together with the diver to a specialist clinic, without the climate being of the interior of the diver's high-pressure chamber.
