Abstract

The invention relates to a method of attaching a free container for defrosted water to the shell of a refrigerant compressor. The essence of the solution lies in the fact that, after surface treatment, a layer of composition is applied to the intended contact surface of the empty container for defrosted water, and after at least 10 minutes, the parts are separated by pressing the joint on both contact surfaces, and the product is unpacked at a temperature of 100 to 135 °C for a period of 8 to 16 hours.

Description

205 647

The present invention relates to a method for attaching a de-icing water tank to a jacket of a throat compressor intended for a small degree of alignment, in particular for combined refrigerators. In the storage area, the storage space of the freezers, the freezers, the combined coolers and the like is condensed by the condensation of the water into a plurality of apparatuses at a lower temperature, and at the same time in the other conversion to form a solid state of the water. The soaring layers of ice deteriorate the heat transfer between the other parts and the polished space. Reduced heat transfer, resp. heat dissipation increases the energy consumption and at the same time negatively affects the temperature in the cold space.

In order to overcome this drawback, the frost from the heat exchanger's cooling portions must be removed, so that it is generally done when the heat sink is interrupted. Defrosting occurs and water is trapped and drained into the residual defroster vessel, which container is attached to the hermetic compressor casing. There are numerous design variants of the freezing containers for hermetic compressors. Most often, the fixing is carried out by means of screws, wherein the material container is selected from the types of corrosion resistant materials, and the type of material subject to corrosion is subjected to a special coating. Screw fastening increases workmanship and increases material costs. There is also a risk of loosening the screws and thus increasing the noise level. Another variation of the design is the attachment of the remaining water defrosting container to the water reservoir, which holds the container and the hermetic compressor casing, or the compressor support or foot. Springs have a tendency to different vibrations, which increases noise, aging changes the force, and mounting with springs is also reflected in increased work.

The fixing of the de-icing water tank with the compressor casing by welding is another constructional variant, however, the increased risk of corrosion is due to the long-term humidity and heat released by the heating unit. Although this solution represents a considerable possibility of meohanism, but the "hard joint" is the transmission of vibrations from the bionic unit to the vessel, which, as a metal, generally has good resonance properties, thus increasing the level of noise emitted from the fire tool.

The aforementioned drawbacks are eliminated by the method of the present invention, which is based on the fact that the defrosting water container is mounted on the sheath of the refiner so that after the surface treatment, as a rule, the paint is applied to the assumed contact surface. the coating of the refining compressor and / or the contact surface of the remaining defrosting water container is applied by a composition layer consisting of 16.0 to 20.0 wt. parts of chloroprene rubber, 2.5 to 6.0 wt. % of rubber, 2.5 to 4.5 wt. parts of an alkylbottle, 50 to 7 wt. % of organometallic solvent based liquid hydrocarbons, 20S 647 10 to 30 wt. parts of ootonic acid esters having a carbon number in the alcohol moiety of 1 to and preferably 15 to 25 wt. parts of an aliphatic and / or aromatic diisocyanate, preferably diphenylmethyldiisocyanate, 0.1 to 2 wt. stabilizers, inhibitors, or other sustained-release substances, with at least 10 min. the parts are pressed by pressing on the contact surfaces and the product is baked at a temperature of 100 to 135 ° C for 8 to 16 hours.

The process according to the invention has a number of advantages, from which it is particularly necessary to consider the fact that it is possible to apply even at a high degree of meohanism, respectively. automates the production of refrigeration units, while ensuring the constant compactness of the refrigeration unit with the de-icing water tank. On the one hand, the formed joint provides sufficient good heat transfer, while on the other hand it has good anti-vibration properties, which ultimately reduces noise *. The procedure is simple and used by components and manufactured industrially. The joint formed has long-term constant properties and is resistant to corrosion.

It is possible to realize the removal of the remaining de-icing water container in a variety of ways, for example by applying the composition to both contact surfaces, i.e. at the surface of the refractory aggregate cover and at the contact surface of the container. Another possibility is that the composition is disposable immediately after the composition of the next application of the composition is carried out at the desired time prior to assembly, while the other application can also be made to the partially or completely hardened layer of the composition. Overall, the process according to the invention is sufficiently flexible to accommodate all common types of mechanized and automated processes for the production of a compact unit with a demineralized water tank.

The de-icing water collector may be metallic and coated with a coating material, e.g., burnt varnish, or the coating may be converted by a technique such as galvanizing.

The deposition of the composition can be carried out by any technique, from praonejčiehonánková read, dipping, spraying and the like. According to the coating technique, the composition of the composition can also be varied within the said range, in particular the content of organic dissolving base liquid hydrocarbons and the content of lower ootonic acid esters. The following steps illustrate the overall process. Example 1

An iron zinc plated die is used as the dewatering container. On the assumed contact surface and on the abutment surface of the sananeslo composites composition, 17 wt. parts of a polypropylene rubber, 5 wt. Tungsten Rubber Parts
