Typical meteorological year (TMY) data can be used in various fields and, based on their reliability, in various industrial areas. For example, the operability of a solar-assisted thermal heat pump, which is an integrated system, largely depends on weather conditions. Furthermore, accurate TMY data are essential for the quantitative designing of heating and cooling systems, which use direct climatic heat sources such as solar and air heat. Herein, a rule of thumb for analyzing the system efficiency of a direct expansion solar-assisted heat pump (DXSAHP) with seasonal variation is proposed. The solar heat collected by the solar absorber was analyzed based on the TMY data, and the heat pump system was evaluated considering the aforementioned solar heat, ambient temperature, and compressor efficiency. Accordingly, this paper presents a detailed numerical analysis of the DXSAHP for three different regions with TMY data in South Korea, namely, the cold (Daegwanryeong), normal (Daejeon) and warm (Jeju) districts. A detailed analysis of the operational performance of the DXSAHP, such as heating performance, work input, and heating COP, was conducted by applying the monthly average climatic conditions recorded in the TMY data.
