Simultaneous heating and cooling systems (SHC) can eliminate both the heating and cooling loads in a single run of the heat pump. This system is effective for buildings that require simultaneous heating and cooling. However, the use of a secondary heat source is inevitable because cooling and heating are not always equal. In a building, assuming that the cooling load is higher than the heating load, the cooling load that cannot be eliminated by a simultaneous cooling and heating system, and it must be covered by auxiliary cooling equipment. In Korean summers, the cooling load in a building is higher than the heating load. In such an environment, the SHC uses less heating energy, resulting in an increased operation of the auxiliary equipment for cooling. To decrease the use of auxiliary equipment and increase the use of SHC, it is necessary to reduce the heating energy of the SHC. For this purpose, an absorption chiller was used to convert the unused heating energy into cooling energy. In addition, to decrease the energy use of the whole system, photovoltaic (PV) panels that can use solar photovoltaic energy were installed to generate a part of the power used in the system, and solar heat energy was applied for the regeneration of the absorption chiller. In this study, the energy consumptions of a conventional SHC and an SHC using solar energy were analyzed by comparing the methods used for a building in which the cooling load is much higher than the heating load during summers.
