  • Patent number: 8261563
    Abstract: An apparatus provides a high efficiency for refrigerator operation. The inclusion of a separate external evaporator and condenser that draws heat away from the common refrigerator condenser allows an increase in the intensity of the cooling process of the cooling agent, thereby diminishing electrical consumption, and decreasing the size and noise of the condenser. This is achieved by structuring the refrigerator condenser with the one tube for the cooling agent of the common refrigerator and another volume for evaporating the cooling substance of the external evaporator and condenser. Moreover, external system of natural cooling has a condenser that is located in the open air and connected to the evaporator with the help of vapor lines and condensed vapor lines.

  • Patent number: 4126105
    Abstract: Boilers with horizontal boiler sections contain in each section several heat exchanger elements for transferring the heat from the heating medium to the heat carrier medium. They have the inherent advantage of needing a connection between sections only on one side so that the dimensional changes during operations are easily equalized and no thermal stresses occur. Heretofore, it has been assumed that the frame of such horizontal boiler sections in which the heat exchanger elements in the form of pipes are secured must be provided with a cooling channel for the liquid heat carrier medium, and consequently the specific heat output in relation to the amount of material used for the construction of the boiler section was considerably decreased.The boilers with horizontal sections in accordance with the invention overcome this problem and require only a reduced specific amount of material as compared with the known boilers of this type.
