Direct Fired Absorption Heat Pump
Working Principle
At begaining of the direct fired absorption heat pump operation, the refrigerant water in the evaporator evaporates away from the surface of the heat exchange tube. As heat in the CHW is taken away from the tube, the water temperature drops and waste heat is thus recycled. The refrigerant steam generated inside the evaporator is absorbed by the concentrated solution in the absorber, and the absorbed heat heats the DHW to a higher temperature. Thus the heating effect is achieved. After that, the LiBr solution in the absorber turns into a diluted solution which is delivered by a solution pump to the heat exchanger. In the heat exchanger, the diluted solution is heated to a higher temperature and then delivered to the generator. At this point, the diluted LiBr solution in the generator is heated by the natural gas and produces refrigerant steam which directly heats the DHW in the condenser once again to a higher temperature. The diluted solution in the generator is concentrated into a concentrated solution which releases heat and cools down in the heat exchanger. Then the concentrated solution is delivered to the absorber, where it absorbs refrigerant steam from the evaporator and turns into a diluted solution. Then the next cycle by direct fired absorption heat pump begins.
