Abstract: The present paper investigates the dynamic energetic, exergetic and environmental performances of two different small-scale LNG cold utilized micro-cogeneration systems under the different climate conditions. The hourly weather data are collected for Singapore, and the dynamic simulations are performed according to the hourly data for each month. Three sessions are determined for the investigations which are the morning, midday and evening sessions. Both designs have their lowest power generation rates at the midday session. The power generation and the exergetic efficiency of the Stirling engine have opposite trend against to the overall power rate of system. The maximum energetic efficiency values are at the midday session while the exergetic efficiencies reach their lowest values at the same session. The environmental analyses show that the emission reductions range between 6.8 and 7.7% when two designs are compared, and the highest emission reduction is obtained at the midday session.
