System for producing domestic hot water coupled with photovoltaic panels and method for improving the efficiency of such a system for producing domestic hot water

摘要

The invention relates to a system (2) for producing hot water for a building (1), characterized in that it comprises a device (3) to aerothermal heat pump producing hot water from an air stream, a controlled mechanical ventilation (4), comprising an air duct system (6) in the building (1) and a ventilation system (3A) for circulating air , the air duct system (6) being coupled to the device (3), the device (3) using air circulated by controlled mechanical ventilation (4) for producing hot water, a set photovoltaic panels (5) on or near the building (1), at least one air duct (6) of the air duct system (6) controlled mechanical ventilation (4) connecting the rear of the all photovoltaic panels (5) and the device (3) through the ventilation system (3A), the use of air chauf fe by the sun at the back of the whole photovoltaic panels (5) to produce hot water.
