Abstract

This study investigates the design modification requirements across architectural, mechanical, and electrical disciplines for implementing an air-source heat pump (ASHP) system in a 253-unit residential apartment building as part of the transition toward carbon-neutral heating systems. The results and limitations of the study are as follows: (1) The results indicate that ASHP performance varies significantly with outdoor temperature, operating conditions, and system capacity, emphasizing the need for appropriate design criteria and operational strategies. Considering equipment noise and vibration, installation in a dedicated basement compartment was found to be the most practical solution. (2) The analysis also shows that approximately 700 kW of ASHP capacity, a 50 m³ thermal storage tank, and about 200 m² of installation space are required, making the availability of mechanical room space a key design consideration. (3) In addition, the introduction of ASHP systems affects electrical load characteristics, requiring modifications to feeder design and additional transformer capacity, which also increases the required electrical room area.
