ABSTRACT:
The invention concerns a heating system incorporating an absorption-type heat pump where the generator is heated by an aerated gas burner combusting a fuel-lean mixture whose efficiency is very high both at full and at part load and whose flue gas has a very low nitrogen monoxide and nitrogen dioxide content.
The mixture of fuel gas and combustion air flows from at least one mixer tube 2 into a mixer 3 and is fired on the burner plate 4 cooled by a rich solution which is arranged at a distance of less than 50 mm from the generator 17.
When the generator is of the vertical type, a burner is preferably installed where the burner plate surrounds the generator concentrically at such a distance from the bottom of the generator that only the central section of the generator is directly heated.
Preferably two heat exchangers are located in the flue duct downstream of the generator to recover the waste heat, including the heat of condensation. The invention calls for the installation of a second burner 19 upstream of the first heat exchanger 9 which will light up and replace the burner for heating the generator, if the temperature falls below a preset lower temperature limit so that the heating system will meet demand even at very low outdoor temperatures.
