Disclosed is a first kind of a lithium bromide absorption heat pump unit. A chilled water by-pass pipe is additionally arranged between a condenser and an absorber, and a refrigerant control valve is positioned on the chilled water by-pass pipe. A solution by-pass pipe is additionally arranged between a concentrated solution pipe and the absorber, and a solution control valve is positioned on the solution by-pass pipe. On the basis of the standard lithium bromide absorption heat pump, the chilled water by-pass pipe is added. Switching the control valves can enable the unit to efficiently rotate according to the heat pump mode when heat source water exists, and enable the unit to rotate according to the vacuum boiler mode when the heat source water can not be supplied caused by a breakdown problem and the like. Therefore, the purpose that the unit can run and manufacture warm water of high temperature whether the heat source water exists or not is achieved. The first kind of the lithium bromide absorption heat
