Description
Technical field
It falls to connect direct combustion dual effect type bromine the present invention relates to a kind of suction-type lithium bromide thermal power plant unit more particularly to a kind of hot water
Change lithium-absorbing formula heat pump unit.Belong to air conditioner technical field.
Background technology
A kind of previous direct combustion dual effect type lithium bromide absorption type heat pump unit as shown in Figure 1, the unit by evaporator 1, inhale
Receive device 2, Direct Fired High Pressure Generator 7, low pressure generator 11, condenser 13, high-temperature heat exchanger 4, low temperature heat exchanger 3, molten
Liquid pump 18, cryogenic fluid pump 19, control system（It is not shown in figure）And pipeline, the valve of connecting components are constituted, when unit operation, with
7 matched burner of Direct Fired High Pressure Generator, 5 burning fuel（Combustion gas, fuel oil）The heat of generation as compensation thermal energy, recycle into
Go out the waste heat source the heat of hot water of evaporator 1, technique use or heat supplication and consumption water of the temperature higher than waste heat source hot water temperature be externally provided,
It is mainly used in while having the place of low-temperature heat source and medium temperature heat demand.The hot water flow 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 Direct Fired High Pressure Generator cannot be excessively high, cause the hot water of this unit to supply
Coolant-temperature gage is relatively low（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）, it is difficult to
Meet to the higher heat demand of heating water's temperature requirement.
Invention content
The purpose of the present invention is to overcome the above shortcomings and to provide a kind of hot water fall connect direct combustion dual effect type suction-type lithium bromide
Heat pump unit so that hot water outlet temperature is increased to >=60 DEG C, meets to the higher heat demand of heating water's temperature.
The object of the present invention is achieved like this：A kind of hot water falls direct combustion dual effect type lithium bromide absorption type heat pump machine of connecting
Group, including evaporator, absorber, Direct Fired High Pressure Generator, low pressure generator, condenser, high-temperature heat exchanger, Low Temperature Thermal are handed over
Parallel operation, solution pump and cryogenic fluid pump.Hot water cross over pipe is provided between condenser and absorber, hot water inlet pipe is connected to condenser
On, the hot water for going out condenser enters absorber by hot water communicating pipe, and hot water outlet pipe is connected on absorber, and hot water flow is to fall
Serial flow.
The beneficial effects of the invention are as follows：
The hot water flow of unit of the present invention is introduced into condensation using serial flow from external system, the lower hot water of temperature
Device enters back into absorber after absorbing the condensation heat heating of refrigerant vapour in condenser.It is higher in waste heat water outlet temperature（Generally
Higher than 30 DEG C）Application conditions under, by improve evaporator and absorber operating pressure and operating temperature, so that hot water is being absorbed
Increasing extent of temperature in device improves, and hot water outlet temperature is increased to >=60 DEG C, to meet to the higher heat supply need of heating water's temperature
It asks.

Specific implementation mode
For ease of more fully understanding the present invention, it is illustrated by example, these examples belong to the scope of protection of the present invention,
But it does not limit the scope of the invention.
Embodiment 1：
Present invention unit as shown in Figure 2, the unit are occurred by evaporator 1, absorber 2, Direct Fired High Pressure Generator 7, low pressure
Device 11, condenser 13, high-temperature heat exchanger 4, low temperature heat exchanger 3, solution pump 18, cryogenic fluid pump 19, control system（In figure not
It shows）And the hot water that is constituted of pipeline, the valve of connecting components falls to connect direct combustion dual effect type lithium bromide absorption type heat pump unit, directly
Refrigerant vapour pipe 10 is provided between combustion type high pressure generator 7 and low pressure generator 11, high temperature water as refrigerant outlet pipe 12 accesses cold
It is provided with hot water communicating pipe 15 between condenser 13, condenser 13 and absorber 2.Hot water outlet pipe 14 is connected on absorber 2, hot water
Inlet tube 20 is connected on condenser 13.
When unit operation, hot water enters condenser 13 through hot water inlet pipe 20, is occurred from low pressure in condenser 13
Go out condensation 13 after the refrigerant vapour of device 11 and the flash steam heat temperature raising of high temperature water as refrigerant, then enters through hot water communicating pipe 15
Absorber 2.Under the service condition of waste heat water outlet temperature >=30 DEG C, the evaporating temperature of evaporator 1 is at 28 DEG C or more, absorber
Solution temperature outside 2 heat exchanger tubes is up to 65 DEG C or more, so that increasing extent of temperature of the hot water in absorber heat exchanging pipe is improved, goes out through hot water
The hot water temperature that mouth pipe 14 goes out unit is increased to >=60 DEG C, can meet the higher heat demand of hot water temperature.
