Description
Technical field
The utility model relates to direct combustion, steam lithium-bromide absorption-type refrigerating machine field, is the lithium-bromide absorption-type refrigerating machine health hot water production energy conserving device when cooling specifically.
Background technology
Lithium-bromide absorption-type refrigerating machine originates from U.S. forties in 20th century, is succeeded in developing by doctor Kai Li, and promotes the use of in the whole world.The sixties in 20th century, 704 first the lithium bromide units in China Shanghai are trial-produceed successfully, because the energy-conservation advantage of its uniqueness, use to 21 century in China's large-scale popularization to the initial stage eighties, along with the input of progress of science and technology and scientific research fund, the lithium bromide refrigerating technology has obtained the variation and the technological improvement of making rapid progress.
Though through technological improvement for many years, still there is a lot of defectives in former lithium-bromide absorption-type refrigerating machine aspect energy-conservation, as: the direct combustion lithium-bromide absorption-type refrigerating machine that uses is produced health hot water when freezing now, the burning of natural gas via combustor is the outer bromize lithium dilute solution of heating high-temperature generator heat-transfer pipe directly, weak solution produces the high temperature refrigerant vapour through heating to concentrate, high temperature refrigerant vapour heating health hot water is to specified design temperature, after health hot water has absorbed the heat of refrigerant vapour, refrigerant vapour condenses into steam condensate, direct and concentrated solution is mixed, and solution concentration and temperature reduce.Producing the health hot water energy-output ratio during refrigeration increases, and efficient reduces, and the terminal use directly increases operating cost, and the circulation that goes round and begins again causes energy waste.
The utility model content
The utility model is in order to remedy above-mentioned the deficiencies in the prior art, a kind of lithium-bromide absorption-type refrigerating machine health hot water production energy conserving device when cooling is provided, this device is used for direct combustion or steam lithium-bromide absorption-type refrigerating machine, produces health hot water and realize that energy resource consumption is minimum in refrigeration.
The technical solution of the utility model is: this lithium-bromide absorption-type refrigerating machine health hot water production energy conserving device when cooling, the high-temperature generator that comprises lithium-bromide absorption-type refrigerating machine takes place with the low temperature that links to each other with high-temperature generator, condenser, be provided with the health hot water heat exchanger on the top of high-temperature generator inner chamber, the outer health hot water import that is provided with of this health hot water heat exchanger and high-temperature generator, the health hot water outlet is communicated with, it is characterized in that, the below of described health hot water heat exchanger is provided with the refrigerant vapour condensed-water recovering device, and this refrigerant vapour condensed-water recovering device is sent the condensate water of health hot water heat exchanger generation into the low temperature generation through piping and control valve, in the condenser.
The further technical scheme of the utility model is that it is refrigerant vapour condensate water ponding dish that described refrigerant vapour coagulates retracting device.
The utility model is to use lithium-bromide solution to concentrate the back absorbs the steam refrigeration easily under vacuum state characteristic through heating, by refrigerant vapour heating health hot water, changes the endless form of health hot water refrigerant vapour condensate water, realizes energy-saving safety operating.
Its principle is as follows:
As everyone knows, be heated to certain temperature and need consume a large amount of energy, same refrigeration also needs to consume a large amount of energy, not only freezes but also make health hot water and satisfy the difunctional instructions for use of user simultaneously with same equipment, needs to consume the double even more energy especially.
But when freezing with lithium-bromide absorption-type refrigerating machine, with the health hot water heating, natural gas is by the lithium-bromide solution in combustor burning or the Steam Heating high-temperature generator.Lithium-bromide solution concentrates the back and produces the high temperature refrigerant vapour through heating, and utilizes the high temperature refrigerant vapour to heat health hot water.After health hot water had absorbed the heat of high temperature refrigerant vapour, at the heat-transfer pipe outer wall surface formation steam condensate of health hot water heat exchanger, the steam condensate after condensing splashed into retracting device ponding dish and stores.Owing to reclaimed steam condensate, lithium-bromide solution concentration raises, and refrigerating efficiency improves, and energy-output ratio reduces.
That is to say, when and refrigeration that obtain the same when user's energy resource consumption is identical, using lithium-bromide absorption-type refrigerating machine of the present utility model compares with existing common lithium-bromide absorption-type refrigerating machine, the health hot water of uniform temperature can also additionally be provided to the user, and this has reduced user's use cost undoubtedly.
The beneficial effects of the utility model are, bromizate the lithium Absorption Refrigerator and not only freeze but also make health hot water, satisfy the difunctional instructions for use of user simultaneously; Volume is little, and cost is low, realizes simple.Production of the present utility model and using method do not have any pollutant emission, help environmental protection, have especially saved the energy, have reduced the operating cost of heating health hot water.Can be widely used in all occasions that needs such as hotel, hotel, chemical industry, food, medicine freeze and need health hot water.
Description of drawings
Figure is a fundamental diagram of the present utility model.
The specific embodiment
As figure.This lithium-bromide absorption-type refrigerating machine health hot water production energy conserving device when cooling comprises that the high-temperature generator of lithium-bromide absorption-type refrigerating machine takes place with the low temperature that links to each other with high-temperature generator, condenser; Be provided with the health hot water heat exchanger on the top of high-temperature generator inner chamber, this health hot water heat exchanger is communicated with the outer health hot water import that is provided with of high-temperature generator, health hot water outlet.These basic structures are same as the prior art to be repeated no more.
Improvement of the present utility model is, the below of health hot water heat exchanger is provided with the refrigerant vapour condensed-water recovering device, and this refrigerant vapour condensed-water recovering device is sent into the condensate water of health hot water heat exchanger generation in low temperature generation, the condenser through piping and control valve.Its groundwork process is:
Natural gas is by the lithium-bromide solution in the thermal source heating high-temperature generators such as combustor burning or steam, the low temperature health hot water enters the health hot water heat exchanger by the health hot water import, health hot water heat exchanger and lithium-bromide solution carry out heat exchange through heating the high temperature refrigerant vapour that concentrates the back generation in high-temperature generator, the low temperature health hot water becomes the high temperature health hot water, discharges through the health hot water outlet and uses for the user.
Temperature reduce to form the refrigerant vapour condensate water after high temperature refrigerant vapour and the heat exchange of health hot water heat exchanger, and the refrigerant vapour condensate water splashes into the refrigerant vapour condensate water ponding dish that is positioned at its below naturally through the heat-transfer pipe outer wall of health hot water heat exchanger and stores.
