Methodology for calculating the average temperature of the walls of the cylinder-piston group of a crosshead piston hybrid volumetric power machine

Based on the heat balance equation, a method for determining the average wall temperature of the cylinder-piston group components of a crosshead piston hybrid power machine has been developed. Mathematical models of the operating processes of a piston compressor and piston pump were used to determine the amount of heat removed from the compressed gas and the heat supplied to the coolant. The implementation features of the integral heat balance equation solution are discussed. The conducted research revealed that the increase in the average wall temperature of the cylinder-piston group is insignificant and within 2 K for the machine under study. Proposals for improving heat removal from the compressor section and the supply of this heat to the pump section have been developed.
