New perspectives for reducing heat and electricity consumption in building are emerging with innovative techniques such as highly insulating glazing and super insulated structures, utilization of solar energy, solar cells, hybrid ventilation solutions, energy efficient and demand-controlled ventilation, as well as integration of solutions, energy production in building. A relatively new innovation is the use of ground-source heat pumps that have become popular for both residential and commercial heating and cooling applications because of their higher energy efficiency compared to conventional systems. In this study, a flat heat pipe is proposed for using the enormous heat capacity of the soil as a heat sink to remove heat from the ambient, integrated the principal idea of a linear reluctance motor for the recirculation of the working fluid. Linear oscillating motors have a long history as rotary motors; but the complexity in the design and difficulties on their control limited the use of them. The motor consists of an iron bar, moving inside a coil. During the path of the iron bar an incremental force appears opposing the movement of the bar. For that reason, it is important to control the system and take advantage of that behavior. Reluctance motors can have high power density at a low cost, making them ideal for many applications. In this study, an implementation of the reluctance motor is proposed for using in a recirculation process of a passive cooling panel for residential buildings. Parametric studies are carried out to optimize the design parameters.
