Facility for producing domestic hot water for an apartment block including a common air-extractor fan

摘要

The installation (10) for the production of hot water in order to house a collective (12) comprising a plurality of individual receptacles (14a - 14h) comprises a network of extraction of the individual (16a - 16h) associated with each individual receptacles (14a - 14h), each individual extraction system is provided with means (18a - 18h) of heat exchange between the extracted air and water to be heated contained in a storage tank (20a - 20h) disposed in the housing for the individual patient, a network of extraction of air (38) which is common to the various individual receptacles, in which the individual networks of extraction (16a - 16h), downstream of the heat exchange means (18a - 18h), the extraction system common air being provided with an extraction ventilator common air (42), and at least one pressure sensor (46, 48) adapted to measure the pressure in the extraction system (44), formed of the networks of extraction of individual (16a - 16h) and of the extraction system common (38), the fan (42) is regulated as a function of the pressure measured by the pressure sensor (46, 48).
