Abstract: Temperature control systems for building tend to be more efficient. In this context, the air-to-air thermoelectric heat pump (THP) with an energy- efficient building is an interesting alternative to classic thermodynamic system. In the study, we focus on the optimal number of thermoelectric modules and the optimal electrical current for three standard cases of coupling: (i) the THP is coupled to an exhaust/supply mechanical ventilation system (ESMVS), (ii) the THP is coupled to an ESMVS and an air-to-air heat exchanger, and (iii) the THP is installed with an ESMVS and an earth-to-air heat exchanger in three different cities in France (Trappes, La Rochelle and Nice). The performance is quantified using two different COP definitions: performance of THP only (COPHP) and performance of THP coupled to energy efficient building (COPu) with seasonal conditions. We show that for each coupling case and each climate, an optimal number of modules exists. It gives the maximum performance of the THP and can be approached for a given set of operating conditions, by simply adapting the electric current for each condition. This method allows achieving the maximum performance and reducing the materials cost compared to the classical design based on nominal conditions.
