As the performance of the building is getting better, the demand for heating energy is decreasing. In this context, the air-to-air thermoelectric heat pump (THP) with a low energy building is a good alternative to classic thermodynamic system in terms of reducing vibration, noise and cost. In the study, we focus on the optimal number of thermoelectric modules and the optimal electric 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, LaRochelle and Nice). This study shows 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 (up to 5.2%) and reducing the materials cost (up to 41%) compared to the classical design based on European nominal conditions NF EN 14511. |
