Heat exchange unit for building, has tank filled with water in which part of tubes are immersed for creating heat exchange between heated heat transfer gas and water of tank, and pump circulating heat transfer gas in tubes

摘要

The unit has a heat transfer gas circuit (12) provided with a series of tubes (9) arranged in end to end manner. A heating unit (1) locally heats the heat transfer gas in circulation. A tank (14) is filled with water (16) in which part of the tubes are immersed for creating heat exchange between the heated heat transfer gas and water of the tank. A pump (20) circulates the heat transfer gas in the tubes. An intermediate heat transfer gas circulation tube ply is connected to a side of a heat transfer gas supply tube (22) and a heat transfer gas evacuating tube (24).
