    Hydrides are used as a means to pump heat from a low grade thermal source, using hydrogen and materials which reversibly and exothermically form hydrides therewith at low temperatures and pressures, and which reversibly dehydride to release large quantities of hydrogen at relatively higher temperatures and pressures, which hydrogen then exothermically recombines with a second hydride species, thereby pumping heat from a given temperature to a higher temperature.

    The invention relates to heat and chemical technology, in particular to compressed air. frames operating on the principle of absorption and desorption of vapors of the working agent in the heat pump mode. Compressors are known that contain hydride elements, mainly niobium, absorbing vapors of hydrogen at low pressure with removal of heat released during heat absorption to a low potential source and desorption of hydrogen at high pressure with heat supply from a source of increased potential l The disadvantage of known compressors is that that they cannot be used as a heat pump without the consumption of heat energy for circulating hydrogen. The aim of the invention is to use a compressor as a heat pump without consuming thermal energy for circulating hydrogen. This goal is achieved by the fact that the compressor contains additional hydride elements, predominantly an alloy of magnesia with nickel, with absorption and desorption characteristics different from the characteristics of the main hydride elements, and a temperature range of operation that does not depend on the temperature range of the latter, forming with the main , the elements are a closed loop for hydrogen circulation, and additional hydride elements are used for desorption of hydrogen at low pressure at scientific research institutes and absorption of hydrogen at high pressure in the process of supplying and removing heat from independent sources. FIG. 1 schematically shows the proposed compressor; in fig. 2 cycle of operation of the compressor in the heat pump mode; in fig. 3 cycle of work. compressor for pumping low to high pressure hydrogen with various hydride elements working with two temperature sources; in fig. C is the cycle of operation of the compressor when pumping hydrogen, with various hydride elements operating with the same pressure difference, but with heat sources of different temperatures. The compressor contains (Fig. 1 niobium, a new hydride element 1 and a hydride element, a 2 element made of an alloy of magnesia with nickel. The compressor works as follows. The niobium element 1 hydride is cooled by a source of heat-low potentiality, for example, ethylene glycol and dry ice. Then niobium "is hydrogenated at a pressure of 2.4bat. At the same time, the hydride element 2 O is heated to 300 ° C and hydrogen gas is desorbed from it. Then element 1 is removed from the bath, washed with methanol solution in acetone and Next, both elements 1 and 2 are surrounded by explosion-proof screens connected by a pipeline with a valve installed on it and the following operations are carried out. The niobium element 1 is heated to a temperature of 130 ° C and the pressure is increased. .P -80.85 atm (see Fig. 2). The valve is opened and the screens are connected to each other, and heating of element 2 is stopped. The temperature in element 2 due to the absorption of hydrogen rises to T.2 425 ° C and the heat released diverted to the consumer. After that, the niobium element 1 is again placed in a bath with ethylene glycol and dry ice. The temperature of element 1 decreases, which leads to its absorption of hydrogen, desorbing from element 2, the temperature of which is maintained at Tz 300 C. Element 1 is cooled to and saturated with hydrogen at 1 at 2.6 atm. The cycle is then repeated as indicated above. Thus, heat is delivered to the consumer at T: 425 ° C while the temperatures of the heat sources are T O C T, T 300 ° C. FIG. 3 shows the mode of operation of the compressor, composed of three hydride elements. If the first element is niobium, and the second is an alloy of iron with nickel, then at temperatures of heat sources T / i 37.8 C and T, 2 79, + ° C, the hydrogen pressure can be raised from P 1 atm to P, 2 8 atm , and the third element to Р} is 20 atm. At the same time, the third element is chosen as -; CMM, so that it absorbs hydrogen at a pressure of 37.8 ° C with a pressure of 8 atm and desorbed hydrogen at a pressure of 79 and a pressure of 20 atm. If there is hydrogen with a pressure of 20 atm, then it can, during absorption, raise its temperature from 37.8 to 79, p. FIG. the compressor works with three hydride elements, respectively, connected to heat sources with temperatures T -7.2C, T 193.3 ° C and T4 538, while the first element is niobium, the second of magnesia-nickel alloy. At these temperatures, the hydrogen pressure in each element rises from. 0.1 atm to 250 atm. The third element must be chosen from such a material so that it is under desorption at a pressure of 0.1 atm. I biased hydrogen at 193.3 ° C, and at a pressure of 250 atm absorbed it at 537.8 ° C. If there is hydrogen, c. at a pressure of 250 atm, then at absorption in the indicated elements it can raise its temperature from (-7.2) to (+538.8) 0. The economic efficiency of the proposed compressor is expressed in increasing the reliability of operation of the compressor during its operation in the heat pumping mode due to the absence of moving parts in it, as well as in the increase of profitability due to the absence of high-grade heat costs for the circulation of hydrogen. Claims: Compressor containing hydride elements, predominantly niobium, absorbent hydrogen vapors at low pressure with removal of heat released during heat absorption to a low potential source and desorbing hydrogen at high pressure with heat input from an extra potential source, characterized in that compressor as a heat pump without the consumption of mechanical energy for the circulation of hydrogen, it contains additional hydride elements, mainly of alloy m Nickel agnesies with absorption desorption characteristics different from the characteristics of the main hydride elements, and a temperature range of operation independent of the temperature range of the latter, forming a closed loop for hydrogen circulation with the main elements, with additional hydride elements serving to desorb hydrogen low pressure and hydrogen absorption at high pressure in the process of supplying and removing heat from autonomous sources.
