The utility model relates to a lithium bromide absorption type first-class heat pump unit, in particular to a throttling device of the lithium bromide absorption type first-class heat pump unit. The lithium bromide absorption type first-class heat pump unit with the novel throttling device mainly consists of a generator, a condenser, an evaporator, an absorber, a heat exchanger, a lithium bromide solution pump, a refrigerant pump, a throttling device, pipes for connecting all components and valves, wherein the throttling device consists of a U-shaped pipe and a water trap, and the water trap is installed at an ascending section of the U-shaped pipe. The throttling device is composed of the U-shaped pipe and the water trap, thereby ensuring the unit to adapt to the operation at different loads and guaranteeing the safety stability of the unit. The unit operates more safely, the evaporator has no cavity, and the refrigerant pump is free of the danger of cavitation; and the highly efficient heat exchange perform
