摘要:
The invention relates to a scraper having a self-supporting form with a central section (18), comprising a first section (10) provided with a scraping edge (A), second and third sections (12, 14) provided on the central section (18), which is supported by a support device (22) and which essentially encompasses the support device (22). Both of said sections (12, 14) together with a bearing surface of the control section which joins them, are formed with an approximately cylindrical inner surface. Said inner surface runs parallel to the extension of the scraper, whereby the scraper is disposed in a rotatable manner about an axis parallel to the extension thereof on the corresponding support device (22) which is formed in a rotationally symmetrical manner, at least in the supporting area. A fourth section (16) is arranged on a supporting surface (26) which is essentially parallel to the surface to be scraped, in a spring actuated manner, pressing against the scraper (32), rotating it around the support device until the edge (A) comes to rest in close proximity against the surface (24) which is to be scraped.

The invention relates to a method for adjusting and maintaining a desired room climate with regard to temperature, humidity and carbon dioxide concentration at a given charge of heat, humidity and carbon dioxide. A fitting amount of outer air is cooled to a saturation temperature and is thus 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 (Mollier diagram), i.e. is provided with a rise of the quotient of the heat charge in relation to the humidity charge (δh/δx).

An ice-filled cold accumulator for repeatedly freezing and melting ice using cooled air or cooling liquid, comprising an elastic shell (2) for a supply of ice, maintained in close heat-transfer contact by means of a substantially dimensionally stable jacket (3) in the vicinity of an air guide or liquid guide, whereby said guide is mounted in order to conduct air that is to be cooled or dehumidified or to conduct the cooling liquid in the ice supply.

The invention concerns a method of cooling contaminated fluids by means of a cooling device which has a pressureless heat-exchanger and indirectly cools via cooling brine, walls (22) in the pressureless environment being sprayed with the contaminated fluid. The rear transfer faces of the walls (22) are cooled to the desired temperature by means of cooling brine from a single-phase fluid, the contaminated fluid and cooling brine each being sprayed through spray nozzles (20) onto the respective surface and collected in corresponding sumps (24, 26).

摘要:
A method for cold transportation of goods that are placed in a hollow-walled refrigerating container (RC), comprising the following steps: storage of a pumpable solution of tiny ice crystals, known as binary ice, having a given composition and temperature, in a binary ice store (BIST) until said binary ice is used for refrigerating or filling purposes; the optionally filled wall of the refrigerating container (RC) that is to be used is emptied via an outlet valve (BIOV) for the binary ice; the emptied wall of the refrigerated container(RC) is filled with stored binary ice; binary ice is allowed to circulate inside the refrigerating container (RC) via filling instruments that are supplied with binary ice from the binary ice store (BIST) until the temperature of the wall drops to a given temperature, whereby the heated fluid that is discharged from the outlet valve (BIOV) is fed to a binary ice fluid store (BIRL); the wall of the refrigerating container (RC) is filled with a given amount of binary ice; the refrigerating container is decoupled from the filling instruments; the binary fluid that results from the melted binary ice is returned to a corresponding binary fluid store (BIRL) in order to produce new binary ice from said binary fluid.
摘要:
The invention relates to a method and device for demonstrating a concentration of a fluid ice mixture (fluid binary ice), comprising the following steps: decoupling a partial current of the fluid, which is then fed into a heat exchanger (16) in which it is heated up to total fusion, while measuring the inlet temperature (tA) and the outlet temperature (tB); further heating the fluid current by an external source of heat and returning the partial current through the heat exchanger (16), while measuring again the inlet temperature (tC) and the outlet temperature (tD); and computing the gas concentration based on the equation Xice = (tC - tD - tB + tA) x (cpfluid / hice), where cpfluid is the heat capacity and hice is the fusion enthalpy of the binary ice.
