Abstract: A method for adjusting and maintaining a desired room climate with regards to temperature, humidity, and carbon dioxide concentration at a given charge of heat, humidity, and carbon dioxide. A proportionate amount of outer air is cooled to a saturation temperature and then dehumidified. The saturation temperature results from the intersecting point of the saturation curve of humid air, and a straight line which extends through the point of state of the air being in the state of the desired climate of the room air, and the point of state of the available outer air in an h,x diagram, i.e., provided with a rise of the quotient of the heat charge in relation to the humidity charge.

Abstract: Method for operating refrigerating plants in which a thermal coupling of an electromotively and/or mechanically driven compression refrigerating plant with a thermally supplied refrigerating plant takes place in such a way that the compression refrigerating plant condenser is cooled by the thermally supplied refrigerating plant.

Abstract: Method for determining changing ice concentration in binary ice volumes with the steps: carrying out mechanical work in the volume to be measured with an electric motor, determining the electric power and mathematical conversion into a measure for the ice concentration.

Abstract: A method for the refrigerated transportation of a product introduced into a hollow-walled refrigerated container.

Abstract: Ice-filled cold storage means for the repeated freezing and, accompanied by the cooling of air or a cooling fluid, melting of the ice, with an elastic sleeve (2) for an ice supply, which is kept by a substantially dimensionally stable jacket (3) under close heat transfer contact at the location of an air or fluid guide and which is set up for moving air to be cooled or dehumidified or a cooling fluid past the ice supply.

Abstract: Method for determining the ice concentration in a liquid ice mixture (binary ice fluid), with the steps: separating a partial flow of the fluid and introducing and heating the partial flow into a heat exchange (16) until complete melting takes place, accompanied by the measurement of the inlet temperature tA and outlet temperature tB, further heating of the fluid flow by an external heat source and return of the partial flow through the heat exchanger (16), accompanied by the measurement of the inlet temperature tC and outlet temperature tO of the return partial flow and calculating the ice concentration according to the equation Xice=(tC−tO−tB+tA)·(cpfluid/hice), in which cpfluid is the specific heat capacity of the binary ice fluid and hice is the enthalpy of fusion of the binary ice.
