Absorption heat pump

If an economizer (ECO) and an absorption heat pump are also integrated into a heating plant, an additional heat yield is possible and fuel consumption is reduced accordingly. For hot water boilers (105 °C flow temperature), this means an increase in efficiency of approx. 20 percentage points, which corresponds to an additional heat yield of 20 - 25 %. For a hot water boiler requiring testing (150 °C flow temperature), a further 5 - 10 percentage points increase in efficiency can be generated. This corresponds to an additional heat yield of 30 - 40 %.

Your advantages

High increase in efficiency and performance from a single source
Reduction in heat generation costs
Significant increase in the degree of biomass utilization
20 - 40 % more heat from the same amount fuel - Increased output of the heating plant without expanding the silo
Low additional maintenance and servicing costs
High partial load capacity of the absorption heat pump (up to 10 % of nominal output)
Stromverbrauch < 1 % der Wärmeleistung der Absorptionswärmepumpe (Kompressionswärmepumpen > ca. 25 %)
Safe operating materials Water and lithium bromide salt
Operation of the absorption heat pump in negative pressure: No media escape in the event of leakage
Conserving resources by reducing biomass consumption
Reduction of visible vapor clouds at Stack through efficient flue gas condensation
Quiet operation of the heat pump

Advantages of an absorption heat pump

Retrofitting existing heating plants

Wood-fired heating plants that are already equipped with a flue gas condensation system can be retrofitted and benefit from the use of the new "Revolution adaptive" combustion control system and an absorption heat pump.
