<p>A heat pump air conditioning unit with a low-pressure difference cycle comprises a water seepage condenser (J<SUB>2</SUB>), an evaporator (J<SUB>1</SUB>) with inner volute tubes and a compressor (M) with inner heat pipes. Outer working fluid, i.e. water, seeps and cycles between the vent fins of the condenser (J<SUB>2</SUB>) and the surface of heat transfer tubes to form forcible heat exchange. The refrigerating cycle of the air-conditioning unit is a figure 8-form cycle, in which absorbent and coolant act as working fluid. By ameliorating the structure of the condenser (J<SUB>2</SUB>), the evaporator (J<SUB>1</SUB>) and the compressor (M), it is possible to further increase the refrigerating capacity and reduce the compressed work in the air conditioning unit according to the present invention. At the same time, the efficiency of the heat pump can be improved.</p> |
