Conversion method of work to heat flow in refrigerating machine Method involves creation in the volume of the working medium of a refrigerating machine of temperature gradient and use of the working medium in a closed thermodynamic cycle. The working medium of the cycle obtains energy in the form of work, obtains heat from a cold heat source and transmits heat to a hot heat source. The working medium pressure varies periodically. The working medium of the refrigerating machine is made in the form of a mixture of substances, between which a reversible chemical reaction is carried out. The method involves use of constant heat exchange between the working medium and the cold and the hot heat sources. Heat flow from the cold heat source to the hot heat source is obtained when a periodic chemical reaction is being carried out in the working medium volume. |
