A water bypass pipe road is set up between pipeline and the main pipe rail for going out condenser, is set on water bypass pipe road by a cooling water
Port valve.
Under the Heating State for having low temperature exhaust heat to extract, weak solution by-passing valve, condenser water as refrigerant by-passing valve, which are in, closes
State, condenser water as refrigerant switching ball valve are in opening；Waste heat water inlet valve and remaining hot water outlet valve are opened, cooling water inlet
Valve and cooling water outlet valve are closed, and it is remaining hot water to flow through in heat-transfer pipe of evaporator；Cooling sea water inlet valve, cooling sea water outlet valve and cold
But water by-passing valve is closed, and hot water inlet valve and hot water outlet valve are opened, and it is hot water to flow through in absorber and condenser thermal transfer pipe.
Remaining hot water cut off the water supply the extraction of no low temperature exhaust heat direct heating state under, weak solution by-passing valve, condenser water as refrigerant
By-passing valve is in opening；Condenser water as refrigerant switching ball valve is closed, waste heat water inlet valve, waste heat water out
Valve, cooling water inlet valve and cooling water outlet valve are closed；Cooling sea water inlet valve, cooling sea water outlet valve and water bypass are closed, heat

In closed mode；Waste heat water inlet valve and remaining hot water outlet valve are closed, and cooling water inlet valve and cooling water outlet valve are opened, and flow through evaporation
In the heat-transfer pipe of device is cold water；Cooling sea water inlet valve, cooling sea water outlet valve and water bypass are opened, hot water inlet valve and
Hot water outlet valve is closed, and it is cooling water to flow through in absorber and condenser thermal transfer pipe, and the cooling water that self-absorption device comes out
It is divided into two-way, enters water bypass pipe road into condenser, another way all the way, flow out unit after out converging.
Another scheme, while water bypass is set on water bypass pipe, on condenser branch pipe is entered again
Set up one and enter condenser cooling water regulating valve；Or triple valve is set in water bypass pipe road bifurcation.Convection current can be achieved
Enter condenser and flow through the regulation of cooling water flow in water bypass pipe.
The utility model can realize cooling, extraction waste heat for supplying, direct heating, the equipment without other auxiliary.Specific behaviour
It is as follows to make principle：
During Winter heat supply, external system valve is switched over, and chilled water system is switched into waste heat water system, cooling water system
Hot-water heating system is switched to, the water bypass newly established is closed, and unit is direct by the carrying vapour of new utility model
The steam type first-class lithium bromide absorption type heat pump unit heat supply process flow operation of heat supply, add in the external condition heat that normally has surplus heat
Cut off the water supply in the case of entering with the improper remaining hot water of external condition in the case that no waste heat heat adds, can produce out it is required in
Warm water.
During cooling in summer, weak solution by-passing valve, condenser water as refrigerant by-passing valve and condenser water as refrigerant switching ball valve are in
Closed mode, the water bypass newly established are in opening, and external system valve is switched over, and waste heat water system is cut
Chilled water system is changed to, hot-water heating system switches to cooling water system, and working steam still enters generator, and cold water enters evaporator, cold
But water is introduced into absorber, and self-absorption device is divided into two-way after coming out, cold into newly establishing into condenser, another way all the way
But water bypass line, unit is flowed out with going out after the cooling water of condenser converges through water bypass.The kind of refrigeration cycle of unit with

Improve and pressure occurs, reach the purpose of dual-use.Hot water outlet temperature is high when reason is heat supply, and condensation temperature is just high, hair
Raw pressure is also high, and the mobilization dynamic of concentrated solution gravity flow is with regard to big, and in refrigeration, cooling water outlet temperature is low compared with hot water temperature, condensation
Temperature is also low, and generation pressure is also low, and the mobilization dynamic of concentrated solution gravity flow is with regard to small, but the resistance change in concentrated solution flow process
Little, to overcome corresponding resistance, the mobilization dynamic that concentrated solution need to be flow automatically improves, unit safety and stability fortune during ensureing refrigeration
OK.After a cooling water bypass part for condenser is entered, the cooling water inflow into condenser is reduced, and cooling water outlet temperature carries
Height, condensation temperature is just high, and generation pressure is also high, and the mobilization dynamic of concentrated solution gravity flow just increases.
Compared with prior art, the utility model has the advantage of：
The steam type first-class lithium bromide absorption type that the utility model passes through the carrying vapour direct heating in new utility model
On the basis of source pump, go out absorber enter the pipeline of condenser and go out condenser main pipe rail between set up a cooling water bypass
Pipeline, and a water bypass is set thereon；Or while water bypass is set on water bypass pipe,
Enter on condenser branch pipe to set up one again and enter condenser cooling water regulating valve；Or one threeway is set in bypass line bifurcation
Valve.By the switching of external system valve with entering condenser cooling water Flow-rate adjustment, put forward generation pressure during cooling condition
Height, solves the generator concentrated solution mobilization dynamic run into when running supplying thermal condition on same unit and running cooling condition
Problem.
Unit is set to realize three kinds of functions：The first external condition extract under normal circumstances remaining hot water heat produce it is required
Middle temperature-heat-source；Remaining hot water occur cut off the water supply under abnormal condition there is no the input of waste heat heat also to produce institute in external condition second
The middle temperature-heat-source needed, the third is exactly to produce low-temperature receiver.The unit operation is very easy, is inhaled in application steam type first kind lithium bromide
The extraction low temperature exhaust heat heat supply of receipts formula source pump needs the occasion of cooling in summer again, from multi-functional steam type first kind bromine
Change lithium-absorbing formula source pump, both can guarantee that the safe and reliable of whole heat supply period, and be not required to be separately provided refrigeration unit again, can be significantly
Reduce investment of equipment cost.So energy energy-saving and emission-reduction realize comprehensive utilization of energy, summer again during the utility model Winter heat supply
Low-temperature receiver can be produced and meet that air-conditioning and production technology use, improve the year operation utilization rate of unit, reduce investment of equipment into
This, has extraordinary economic benefit and social benefit.
