Fig. 88 Graph of the total thermal power consumed in the summer regime
power given by the Stirling engine greater than 5 kW (for 5 kW, the graph
representing the battery voltage is the one shown in Fig.
84
). This will lead to an
average value of the thermal power in summer regime of about 18
-
20 kW. It is
obvious that the thermal energy demand in summer mode is much lower in
Model 5, but using the Stirling engine to produce electrical energy for air
conditioning leads to dissipation of large quantities of thermal energy. Although
air conditioning installations using electrical equipment are more advantageous
in terms of energy consumption, it is important to consider the qualitative
aspects of the air conditioning process. The achievement of the adsorption air
conditioning equipment has obviously qualitative advantages, such as: the
thermal transfer is done through convectors, which have the advantage of a
thermal comfort as compared to the classic conditioning equipments; the cold
accumulating tank included in the system allows the balancing of the temper-
ature level inside the residence etc.
