Abstract

The energy transition from fossil fuels to renewable energy technologies is getting important to achieve carbon neutrality in 2050. This research investigated the energy saving potential of simultaneous heating and cooling heat pump based next generation district heating and cooling systems for a zero energy community. For this purpose, four university campus buildings in Seongnam-si, Gyeonggi-do was selected as a case study. In this paper, the campus thermal load and electric energy consumption was modeled by DesignBuilder software, and Design-Expert software was used to calculate the COP of heat pump. As a result, it was found that the proposed heat pump integrated with district heating and cooling system can reduce 23.0% of electricity consumption compared with a conventional air source heat pump system and 9.5% of that compared with ground source heat pump system, respectively.
