Abstract |
Simultaneous Heating and Cooling systems are advantageous when heating and cooling loads occur simultaneously in a building; the usage of
auxiliary heat sources is inevitable because the occurrence of the loads may vary. Since the auxiliary heat source has a lower COP than the
simultaneous heating and cooling systems, more energy is required when removing the same amount of load. To reduce energy, the usage of
simultaneous heating and cooling systems and auxiliary heat sources must be increased and decreased, respectively. In this study, a process
that can determine the heating set temperature in real-time was proposed to increase the usage of simultaneous heating and cooling systems
for buildings where the cooling load exceeds the heating load. This process determines the temperature for the next point using the heating
temperature of the previous point and the energy inside the tank. These results confirmed that energy can be reduced while maintaining a
more pleasant temperature. |
