Abstract

Natural energy use is important to reducing the energy consumption of buildings. However, there are advantages and disadvantages to using natural energy in traditional systems. Further reducing energy consumption with traditional systems is difficult. Therefore, we proposed a multi-source and multi-use heat pump (MMHP) to achieve higher efficiency than traditional systems. The MMHP system connects multiple heat sources such as solar heat, the ground, and air and multiple heat uses such as cooling, heating, and a hot water dispenser with a water loop. Each type of heat use side can utilize heat efficiently. However, there is a distinct lack of highly efficient hot water dispensers available. Therefore, we developed the instantaneous hot water dispenser based on a water source (IHWD WS) heat pump. In this study, we developed a prototype of the IHWD WS heat pump. The coefficient of performance of the IHWD WS heat pump was 5.2 in winter and 8.5 in summer. In addition, we developed a performance curve of the prototype. The performance curve of the prototype was modeled, and the model accuracy was confirmed to be within 4%.
