While going to hold the second edition of the French Congress of Heat Pumps, CEP MINES ParisTech presented a study of the performance of a system coupling a heat pump and a photovoltaic cell.

MINES ParisTech CEP (Centre for Energy and Processes) participated in the PACAirPV project. This experiment consisted of coupling a photovoltaic panel and a heat pump. The original idea was to combine existing technologies to optimize energy performance and achieve a low-energy building, see a positive energy building.

CEP MINES ParisTech intervened to make a computer simulation of the project to assess its feasibility and design help.

His calculations were used to estimate the heating requirements of 27 kWh / m² / year and those refresh to 4 kWh / m² / year. The simulation also identified a need for storage, production and consumption of energy are uncorrelated. This storage has taken the form of a second hot water.

Simulation developed by MINES ParisTech has taken into account the dynamic aspects especially related to cycles on / off of the CAP and simulated using both a storage heat a hot water tank. The tool has sought the best compromise between the reliability of the calculation results and the speed, or to help with the design, or to go even further by performing sensitivity studies and optimization.

The installation works since the beginning of the year 2012. The first results in validation leave appear significant energy savings. They totally validate the simulation by Mines ParisTech.

The concept from the program PACAirPV has been patented.

This experiment allowed the successful CEP MINES ParisTech test its software simulation with a thermal project original and powerful. Building on this success the CEP will add this to the coupling system simulation tool overall thermal buildings (COMFIE tool) in order to offer even more opportunities for manufacturers, consultants and master works.

The Center for Energy and Processes (CEP) focuses its research on the study of complex energy systems. Its objective is to contribute to the mitigation of environmental impacts by improving energy efficiency, reducing CO2 emissions and renewable energy sectors Building, Industry and Transport.
