load, the proportion of irreversible loss changes little except at the highest speed.Key words:gasoline engine; exergy balance; waste heat recovery; thermal efficiency; energy conservation... efficiency of internal combustion (IC) engine, exergy analysis was conducted on a passenger car gasoline engine. According to the thermodynamic theory of IC engine, in-cylinder exergy balance model......
. The potential drop of the system, freeze profile and heat balance were analyzed to evaluate their variation with technical parameters when designing the 150 kA conventional cell based drained cell... and change the thermal input and output of the cell, so it is necessary to study the heat balance issue based on designing the lining structure and selecting appropriate operational technologies. ......

shows that the coefficient of performance of the system reaches 3.63 in summer and 3.49 in winter, respectively. The heat balance in underground rock mass is acquired basically throughout the year... and extract the heat from the source in winter for supply heat for end user. If the heat balance of discharging and extracting could not be achieved throughout the year, the temperature of ground......
