Danstoker - Model HP -Absorption Heat Pump
The design of Danstoker’s absorption heat pumps is based on the need for energy optimization. An extra chilling of the exhaust gases makes it possible to transfer the condensing heat in the vapour steam to further improve the system efficiency. Unlike a compressor heat pump, the absorption heat pump is driven by a high-temperature energy source instead of electric power.
The absorption heat pumps have evaporator chilling capacities from 150 kW to 5,000 kW. The heat pump ”borrows” energy from the system to run the generator, and transfers/returns the borrowed energy to the system together with the energy extracted from the waste heat (exhaust gases) by the evaporator. The ratio between the total energy produced and the energy ”borrowed” is 1.7. This ratio is known as the COP value.
