    METHOD OF ICE FORMATION PROTECTION IN REFRIGERATION ANDVENTILATION DEVICES
    DISCLOSURE OF THE INVENTION Field of the invention The present invention relates to means for removing condensation from heat exchangers, namely, refrigerators, ventilation devices, air conditioners, heat pumps, recuperators. Technical level During the operation of refrigeration, ventilation systems, air conditioners, heat pumps, recuperators, the air is cooled when it is passing through heat exchangers, moisture vapor condenses on the cooled surfaces and heat transfer parts, turning into ice crystals. Currently, such methods are known to combat the formation of ice as additional heating of the air, the transition of plants from cooling to defrosting mode, preparation of air by the method of drying. All existing technologies are aimed at preventing ice and therefore require significant energy costs to maintain the trouble-free operation of the heat exchanger. Their efficiency is reduced in proportion to the reduction in outdoor air temperature and humidity. The state of the art is known as "Method for Removal of Condensate from a Condensate Heat Exchanger with Hydrophilic Material and Device for its Implementation" (Patent No. 2183799, Application dated August 20, 2000, brought into force on June 20, 2012, patent holder: Rocket Space Corporation "Energy" S named after Korolev S.P. Open Joint Stock Company). N The invention relates to space technology, specifically to methods of S 25 removing condensate from the heat exchangers of air conditioning systems of the S inhabited compartments of spacecrafts of various application. In addition, the E invention can be used in surface air conditioning systems serving rooms 3 particularly sensitive to drip moisture. The disadvantage of this technical solution 3 is the complexity of its implementation and its focus on application in zero gravity O 30 conditions. "Condensate catcher" is also known from the state of the art (Patent No. 75018, applications dated February 20, 2008, brought into force on July 20, 2008).
    The useful model refers to the field of thermal power engineering, more specifically to condensate catchers, which are part of heat exchangers that use water vapour as a heat transfer medium. The above mentioned technical solution represents a condensate catcher consisting of a condensate collector connected to the pipes of the heat exchanger and a device for removal of condensate from the condensate collector, which is distinguished by the fact that the condensate catcher is equipped with a pipe or a tube for removal of condensate from the condensate catcher, the inlet opening of the pipe or tube is located at a level that ensures that during the removal of condensate it is immersed in the liquid, mainly condensate, with the connection point between the condensate collector and the heat exchanger pipes located at the top of the condensate collector above the surface of the accumulated condensate.
    The disadvantage of this technical solution is that it is aimed at removing condensate at a positive air temperature, so the function of condensate removal is not fulfilled when the temperature drops.
    To avoid condensation, foam-insulated heating elements mounted on at least one side wall and/or on the device door frame are also used. The disadvantage of heating elements, such as electric heaters, is relatively high energy consumption. It is known to use heating elements in the form of foam- insulated pipelines through which the compressed refrigerant flows. The compressed refrigerant generates excess heat generated in the refrigerant circuit of the device, which heats the corresponding surface and prevents unwanted condensation.
    S The disadvantage of such heating elements is that refrigerant pipelines are N 25 expensive and very difficult to produce. On the outer surface pressure-sensitive S areas may occur. Additional disadvantages are the relatively high power & consumption, and therefore high energy costs, the possibility of local overheating = and, under certain circumstances, the effect on the temperature inside the device. 3 Thus, all currently existing technical solutions in this area are aimed at 3 30 heating the heat exchangers that are part of the refrigeration and ventilation O systems.
    Conseguently, the technical problem, the solution of which is provided by the use of the claimed invention, is the lack of technical means and methods for the protection of refrigeration and ventilation systems, which allow to exclude ice formation of heat exchangers without significant energy consumption. Disclosure of invention The claimed invention is proposed in order to solve the above problem and, consequently, the technical task of the present invention is to expand the arsenal of technical means to protect refrigeration and ventilation systems against ice formation without significant expenditure of electricity.
    The technical result of the claimed invention is to ensure the possibility of preventing the freezing of heat exchangers when the condition for the reduction of electric power consumption to ensure this process is reached.
    The technical result is achieved by the implementation of the method of mechanical oscillations which prevents ice formation. The result is achieved due to the fact that high-frequency oscillations are fed to the heat exchanger and as a result of their influence icing loses the ability to hold on the surface of the heat removal elements.
    The following elements are required to ensure that ice is removed in the specified manner: a frequency generator, frequency transmitter, microcontroller, temperature and humidity sensors.
    These elements are connected to each other in such a way that sensors and a frequency generator are connected to the microcontroller, the frequency transmitters are connected to the frequency generator. The emitted frequencies, in turn, are installed on heat exchangers.
    o In order to achieve this technical result, the temperature and humidity O 25 sensors take readings of the air condition and send them to a microcontroller, which O in turn commands the freguency generator to generate the operating freguency 0 and force for the frequency transmitter. The frequency transmitter converts the I electrical signal into mechanical vibration, which destroys the ice layer formed.
    - During the operation of the freguency transmitter, due to the difference in LO 30 density of the heat exchanger material and ice crystals, the ice crystals peel off N (reject) the heat transfer surfaces of the heat exchanger.
    N Depending on the materials used for the manufacture of heat exchangers, as well as its design and shape, the emitter of frequency vibrations and the mutual arrangement of elements are selected. The control equipment is selected on a case-by-case basis, depending on the selected frequency vibration transmitter.
