Abstract
The invention discloses a jet adsorption type central air-condition. It is composed of refrigerator, evaporator, heat exchanger, radiator, vapor distributor, jet ejector, condenser, solvent pump and connecting pipeline. Water solution of lithium bromide is adopted as working medium. New technical procedure is used to realize its own interior thermal circulation. The invention solves the drawbacks of high steam consumption, high electrical energy consumption and high consumption of water, and these problems occur in the existing heat energy compensation type refrigerator.
Description
The present invention relates to a kind of refrigerating plant, especially a kind of absorption, interior recirculated water steam sprays central air-conditioning.
Directly utilizing thermal compensation to realize freezing is present the most frequently used refrigeration modes, in using, prior art utilize the refrigeration machine of thermal compensation that the injecting type of steaming and lithium-bromide absorption-type refrigerating machine are arranged, steam-ejector refrigerating machine is mainly by refrigerator, injector, parts such as condenser are formed, during work, (0.4～0.6MPa) sprays into pump chamber by injector nozzle with 1000～1200m/s speed to working steam, be forced to discharge with the chilled water vapor mixing, like this, by constantly evaporimeter mesolow chilled water steam being taken away, keep the chilled water evaporation of in evaporimeter, absorbing heat and produce the required high vacuum of refrigeration.The major defect of steam jet refrigerator is that energy consumption is big, and working steam pressure and cooling water temperature change to the refrigeration machine performance impact also greatly.Because the higher obsolete product that is listed at home of energy consumption.Lithium-bromide absorption-type refrigerating machine mainly is made up of parts such as generator, condenser, evaporimeter, absorber, solution pump, choke valves.During work, bromize lithium dilute solution is raise by the working steam heating-up temperature in generator in solution pump is admitted to generator, and seethes with excitement under certain pressure, makes moisture from coming out to produce a large amount of refrigerant vapours, and solution is concentrated.The refrigerant vapour that generator produces enters condenser, the water quench that is condensed in the device condenses into water as refrigerant, water as refrigerant enters the evaporimeter water pond through choke valve, because the pressure of evaporimeter is very low, water as refrigerant evaporation immediately behind the heat of having drawn the chilled water in the evaporator tube forms water as refrigerant steam, thereby the temperature of chilled water is reduced, constantly carry out in order to make in the evaporimeter cryogen evaporation of water endothermic process, the water as refrigerant steam that produces must be taken away, pyrosol after concentrating in the generator enters absorber through choke valve, be absorbed the water quench in the device, temperature reduces and has the ability of strong absorption water as refrigerant steam, so circulates and just can realize continuous cooling.The major defect of lithium-bromide absorption-type refrigerating machine has: (1) owing to directly utilize heat energy, the heat extraction load is big, and thermal energy consumption is big.(2) cooling-water consumption is big, finish because of whole refrigeration system heat exchange all needs water, thereby the water resources consumption waste is big, (3) power consumption is big, the water quench circulation needs many high powered water pumps to finish, and energy consumption is bigger, and above shortcoming has restricted applying of lithium bromide refrigerator greatly.
The objective of the invention is to overcome the weak point that exists in the above-mentioned prior art application, and a kind of water resources consumption and power consumption of can reducing significantly is provided, reduce steam consumption quantity, circulate in realizing, improve a kind of steam jet suction type central air-conditioning of heat utilization efficiency.
Technical scheme of the present invention is: a kind of jet suction type central air-conditioning, by refrigerator, evaporimeter, heat exchanger, divide drum, radiator, solution pump, three above injectors, two above condensers and connecting pipe constitute, and lithium bromide water solution is arranged in evaporimeter, evaporimeter links with minute drum and heat exchanger respectively by pipeline, divide drum to link with injector respectively by pipeline, injector links by pipeline and condenser respectively, and injector links by pipeline and refrigerator, condenser links by pipeline and solution pump, solution pump links by pipeline and heat exchanger, and heat exchanger links by pipeline and evaporimeter respectively, and condenser links by pipeline and solution pump and radiator respectively.
The present invention is on the basis of comprehensive existing steam-ejector refrigerating machine and lithium-bromide absorption-type refrigerating machine advantage, creationary with lithium bromide water as refrigerant steam as the working steam bromize lithium concentrated solution as the condensation absorbent, released the novel steam jet suction type central air-conditioning of a kind of water saving, economize on electricity, saving steam.
Technical scheme of the present invention compared with prior art has following advantage:
1, can reduce the consumption of steam energy consumption and recirculated water significantly.Because existing steam jet vacuum equipment all is to adopt recirculated water as cooling medium, vacuum environment is obtained in injection with water vapour, so water consumption and energy consumption are all very big, and the present invention adopts the lithium-bromide solution of specific concentrations to replace the aqueous solution of the prior art as the circulation working media, closed circulation operation in device, for vacuum plant provides high-quality working steam and circulating condensing agent, so can reduce steam energy consumption and water resources consumption significantly.
2, improved the environmental suitability of vacuum plant, because the present invention has adopted new working media, water-saving result is obvious, and in addition, vacuum plant adopts the sealing inner loop mode when work, be not subjected to the influence of external environment substantially, has improved the environmental suitability of device.
3, can significantly reduce equipment investment.Because the present invention creatively adopts bibulous lithium bromide water solution more obvious than cold doubtful effect as absorption condensation agent and water, so just can reduce the outlet pressure of steam jet ejector greatly, thereby reduced the resistance of bleeding in the condenser, the allocating power of injector is reduced greatly, compared with prior art structure is simple more compact so this installs, and the investment of whole vacuum plant also significantly reduces.
Now with 1163KW (100 * 10
4Kcal/h) refrigerating capacity is an example, and with 0.5 yuan/kilowatt, steam is in 25 yuan/ton as if the electricity charge, and calculate by moving 100 days continuously summer:
1, energy-conservation: the required steam expense of steam-ejector refrigerating machine, steam consumption are got 4t/h
4 * 24 * 100 * 25=240000 unit
The required electricity charge of steam jet refrigerator, 100KW/h is measured in power consumption
100 * 24 * 100 * 0.5=120000 unit, two add up to 360000 yuan.
Lithium-bromide absorption-type refrigerating machine steam expense, steam consumption are got 2t/h
2 * 24 * 100 * 25=12000 unit
The lithium-bromide absorption-type refrigerating machine electricity charge, 120KW/h is measured in power consumption
Two in 120 * 24 * 100 * 0.5=144000 unit adds up to 264000 yuan.
Jet suction type central air-conditioning steam takes, and steam consumption is got 1.5t/h
1.5 * 24 * 100 * 25=9000 unit
Spray and absorb the central air-conditioning electricity charge, 60KW/h is measured in power consumption
Two in 60 * 24 * 100 * 0.5=72000 unit adds up to 162000 yuan
2, water saving: steam jet refrigerator and lithium-bromide absorption-type refrigerating machine per hour need 320 tons of recirculated cooling waters, and jet suction type central air-conditioning of the present invention per hour needs 30 tons of cooling water less thaies.
Adopt in sum jet suction type central air-conditioning of the present invention respectively than steam jet refrigerator and, lithium-bromide absorption-type refrigerating machine energy-conservation 55% and about 40%, water saving is more than 90%, thereby market prospects are very wide.
Below in conjunction with drawings and Examples the present invention is described in further detail.
