Description

A kind ofly use that the suction-type lithium bromide at solar energy and water source heats, refrigerating plant
Technical field
The utility model relates to a kind of air-conditioning, particularly a kind ofly uses that the suction-type lithium bromide at solar energy and water source heats, refrigerating plant.
Background technology
At present, under the advocating of national energy-saving and emission-reduction, reduce building energy consumption, particularly air conditioning energy consumption is particularly important, so find the research emphasis that novel renewable energy becomes HVAC worker.China is located in the east in the Eurasia, the Northern Hemisphere, has than more rich solar energy resources.On the other hand, China's surface water resources comparatively horn of plenty, occupies the 6th, the world.Therefore, may be used for air conditioner industry containing energy in solar energy resources and surface water.Lithium bromide absorption type heat pump has the feature of the strong and environmental protection of little power consumption, energy applicability, is widely used in field of air conditioning.
Because the heat pump of single source drive form has some limitations, govern respective development.If two kinds or two or more multi-form heat pump are combined operation, then both can overcome the deficiency of single source heat capacity, the problem of fluctuation of service, have again good complementation and matching.At present, heat pump system mainly exists with two thermal source combining operation mode, mainly contain Solar-ground source heat pump, solar-powered-air source heat-pump, solar energy-water source heat pump and solar energy-lithium bromide absorption type heat pump etc., these pair of thermal source associating heat pump solves the problem of single source heat supply deficiency preferably.But because their efficiency is lower, range of application is less.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of and uses that the suction-type lithium bromide at solar energy and water source heats, refrigerating plant.Its structure is simple, and invest little, floor space is little, is convenient to safeguard.
The technical scheme in the invention for solving the technical problem is: boiler first loop to be sealed with solar heat-collection plate by the first valve, the first heat-exchanger pump and communicates, and second servo loop to be sealed with the heating pipe line of generator by the second valve, the second heat-exchanger pump and communicates; The first via absorbent outlet of generator is communicated with the absorbent inlet seal of condenser by the 3rd valve, the absorbent outlet of condenser is communicated with the absorbent inlet seal of evaporimeter by expansion valve, the absorbent outlet of evaporimeter seals with absorber and communicates, the absorbent of absorber is imported and exported by communicating with solution heat exchanger one tunnel seal for pipe joints with the 4th valve, solution pump, and another road pipeline of solution heat exchanger is imported and exported sealing with the second road absorbent of described generator and communicated; The cooling water outlet and inlet of described evaporimeter is communicated with a road seal for pipe joints of heat exchanger by the 5th valve, the first water supply pump, and another road pipeline of heat exchanger to be sealed with outdoor water source by the 6th valve, the second water supply pump and communicates.
The utility model has following advantages: 1), simultaneously use lithium bromide absorption type heat pump and water source heat pump system, and by unified for the two equipment, system is simple, and initial cost is low; 2), stable; 3), maintenance is convenient to; 4), floor space is little.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model schematic diagram.
Detailed description of the invention
As shown in Figure 1, boiler 4 first loop to be sealed with solar heat-collection plate 1 by the first valve 3, first heat-exchanger pump 2 and communicates, and second servo loop to be sealed with the heating pipe line of generator 8 by the second valve 6, second heat-exchanger pump 5 and communicates; The first via absorbent outlet of generator 8 is communicated with the absorbent inlet seal of condenser 13 by the 3rd valve 12, the absorbent outlet of condenser 13 is communicated with the absorbent inlet seal of evaporimeter 15 by expansion valve 14, the absorbent outlet of evaporimeter 15 seals with absorber 19 and communicates, the absorbent of absorber 19 is imported and exported by communicating with solution heat exchanger 16 1 tunnel seal for pipe joints with the 4th valve 17, solution pump 18, and another road pipeline of solution heat exchanger 16 is imported and exported sealing with the second road absorbent of described generator 8 and communicated; The cooling water outlet and inlet of described evaporimeter 15 is communicated with a road seal for pipe joints of heat exchanger 22 by the 5th valve 21, first water supply pump 20, and another road pipeline of heat exchanger 22 to be sealed with outdoor water source 25 by the 6th valve 23, second water supply pump 24 and communicates.
The second described heat-exchanger pump 5 is connected in series auxiliary heater 7 with between generator 8; Second road absorbent outlet of described generator 8 is entered inlet seal by the 7th valve 9 with the absorbent of described condenser 13 and is communicated, and the 3rd road absorbent of generator 8 is imported and exported and communicated by the 8th valve 11, compressor 10 sealing.More lowly can utilize the heat energy of compressor at pressure, improve absorbent cycle efficieny, make up the deficiency of solar heat-collection plate heat capacity.Its principle is: when higher from boiler 4 hot water temperature out, open the 3rd valve 12, close the 7th valve 9 and the 8th valve 11, at this moment compressor 10 does not run.When from boiler 12, hot water temperature is out lower, close the 3rd valve 12, open the 7th valve 9 and the 8th valve 11, at this moment compressor 10 runs, from generator 8 steam out all by compressor compresses to the state higher than occurrence temperature, the heat release in generator 10 of steam after compression, then enters condenser 13 by the 7th valve 9.
The upper fixing spray thrower 26 of described absorber 19 inner absorbent outlet.Can increase the absorption efficiency of lithium-bromide solution, the lithium-bromide solution from solution heat exchanger 16 is entered with the form of spraying in absorber 19, lithium-bromide solution is absorbing in the process that steam falls, the heat that simultaneously stability self produces and raised temperature.Increase the heat exchange area of lithium-bromide solution, thus absorption efficiency is raised.
Utilize the change of lithium-bromide solution concentration to obtain hot and cold amount, in device, main working medium is lithium-bromide solution, water, and wherein lithium bromide is absorbent, and water is cold-producing medium.Utilize solar heat-collection plate 1 to transfer solar energy to heat energy water is heated, enter boiler 4 from solar heat-collection plate hot water out through heat-exchanger pump pressurization and store.The hot water that boiler 4 stores is used for lithium-bromide solution in heating generator 8, refrigerant vapour is parsed, enter condenser 13, in condenser 13, refrigerant vapour is cooled condenses into liquid, then by expansion valve 14 step-down, send into evaporimeter 15, evaporimeter 15 absorbent evaporates after absorbing the heat from outdoor water source 25, absorbent after evaporation enters absorber 19, absorbed by the dense lithium-bromide solution from generator 8, then enter generator 19 by solution heat exchanger 16 and evaporate, form a circulation thus.
