Method for estimating the operating time in the compressor mode of a reciprocating hybrid power machine with regenerative heat exchange

The influence of the average wall temperature on the main consumption and energy characteristics of a reciprocating hybrid power machine (RHPM) with regenerative heat exchange has been studied. A significant effect of a change in the average wall temperature on the supply coefficient and the indicator isothermal efficiency of the RHPM operating in the compressor mode is shown. Based on the results obtained, a method has been developed for determining the operating time of the RHPM in the compressor mode, based on the given average value of the indicator isothermal efficiency in the studied interval of the average temperature of the wall of the surface of the working chamber, or the operating time of the RHPM.
