Unit run when, using from steam inlet pipe 8 enter steam type high pressure generator 7 working steam as compensate thermal energy, recycle into
The waste heat source the heat of hot water of evaporator 1 out externally provides technique use or heat supplication and consumption water that temperature is higher than waste heat source hot water temperature,
It is mainly used in while having the place of low-temperature heat source and medium temperature heat demand.The hot water process of this unit uses positive tandem junction
Structure, hot water enter back into condenser after being introduced into absorber heat absorption heating, finally go out unit from condenser.Due to the work of condenser
Make pressure, operating temperature is limited to the service requirement of steam type high pressure generator cannot be excessively high, cause the hot water of this unit to supply
Coolant-temperature gage is lower（Generally less than 50 DEG C）, it is only applicable to the lower place of heating water's temperature requirement（Such as floor heating heat supply）, difficult
To meet to the higher heat demand of heating water's temperature requirement.
Utility model content
Purpose of the utility model is to overcome the above-mentioned shortcomings and provide a kind of hot water, series connection steam double-effect type lithium bromide is inhaled
Receipts formula heat pump unit, hot water outlet temperature are increased to >=60 DEG C, meet to the higher heat demand of heating water's temperature requirement.
What the purpose of this utility model was realized in：A kind of hot water falls to connect steam double-effect type lithium bromide absorption type heat pump
Unit, including evaporator, absorber, steam type high pressure generator, low pressure generator, condenser, high-temperature heat exchanger, Low Temperature Thermal
Exchanger, condensate heat exchanger, solution pump and cryogenic fluid pump.Hot water inlet pipe is connected on condenser, and the hot water of condenser passes through heat out
Water communicating pipe enters absorber, and hot water outlet pipe is connected on absorber, and hot water process is serial flow.
The utility model has the beneficial effects that：
The hot water process of the utility model unit is first from external system, the lower hot water of temperature using serial flow
Into condenser, absorber is entered back into after the condensation heat heating of refrigerant vapour is absorbed in condenser.In waste heat water outlet temperature
It is higher（Generally greater than 30 DEG C）Service condition under, by improve evaporator and absorber operating pressure and operating temperature, make
Increasing extent of temperature of the hot water in absorber improves, and hot water outlet temperature is increased to >=60 DEG C, is wanted with meeting to heating water's temperature
Seek higher heat demand.
