An Evaluation of Apartment Heating System for Energy-Saving

This study conducted a comparative analysis of types of apartment heating systems by considering energy consumption amount through a simulation, and the results can be summarized as follows; in the simulation of three apartment heating systems, which were floor radiation, capillary radiation, and EHP, when applying 1st (within 5 years, case 2, 30%) and 2nd (within 10 years, case 3, 50%) energy reduction goals, case 3 (after 10 years) of EHP system was found to achieve a reduction in energy consumption of 25% compared with the floor radiation system, and of 35% compared with the capillary radiation system. These research findings will enable energy savings by changing apartment-heating systems from being fully dependent on the current floor radiation heating and combining with EHP.
