Description
The utility model relates to a kind of hot water lithium bromide absorbing refrigerating unit, and it is higher to relate in particular to a kind of thermal source hot water temperature, and needs lithium bromide water absorption refrigerating plant that the hot water temperature is even lower.
Hot water lithium bromide absorbing refrigerating unit utilizes the absorption refrigeration principle to realize freezing with hot water as thermal source.Its process of refrigerastion is that hot water heating lithium-bromide solution makes it produce water vapour and concentrates, the water vapour that produces is condensed into water as refrigerant in condenser, water as refrigerant enters the heat of absorption cold water in the evaporimeter and evaporates after throttling, and cold water temperature is reduced and the generation refrigeration.The refrigerant vapour of evaporation is absorbed by the concentrated solution of coming from generator, and is thinning behind the concentrated solution absorption water vapour, and weak solution is sent to the generator heating again and concentrates, and isolates water as refrigerant, and so continuous circulation has constituted the single-action circulation of lithium bromide absorbing type refrigeration.In this single-action circulatory system, have only an evaporimeter and an absorber to finish whole cold water cooling and cooling water temperature-rise period, its evaporating pressure is corresponding with cold water outlet temperature in same cavity, the absorbent solution temperature is corresponding with cooling water outlet temperature, the corresponding water vapor pressure of weak solution is low in absorber for this reason, temperature is high, and its concentration is also high.Because weak solution concentration can not be even lower, weak solution concentration is dense, its occurrence temperature height.In condenser, cooling water is finished whole temperature-rise period, and its condensing pressure is corresponding with cooling water outlet temperature for this reason.In generating process, condensing pressure is equal to generation pressure substantially.In the solution generating process, the pressure height takes place, its temperature that takes place that comes to life is also high, the heating source temperature can not be reduced for this reason, and heat source of hot water is not fully utilized.
The purpose of this utility model is to provide a kind of and the thermal source hot water temperature can be even lower, thereby makes heating source obtain the hot water lithium bromide absorbing refrigerating unit of more effective utilization.
The utility model is achieved in that in this device, by segmentation with the cooling water temperature-rise period of the segmentation of the whole temperature-fall period of cold water, absorption site, the segmentation of condenser cooling water temperature-rise period, the segmentation of generator hot water temperature-fall period, differ from 5 ℃ as the out temperature with cold water and be divided into 1.7 ℃ and 3.3 ℃, the out temperature of cooling water differs from 6 ℃ and is divided into 2 ℃ and 4 ℃.The out temperature of hot water differs from 50 ℃ of two-period forms that are divided into 17 ℃ and 33 ℃.After the segmentation generator, condenser, evaporimeter, absorber are separated too, also divide generator, condenser, evaporimeter, the absorber of making same number by the segments of cold water, cooling water, hot water.Be divided into three temperature difference sections as the temperature difference, simultaneously generator, condenser, evaporimeter, absorber also all be divided into three the cold water temperature difference, cooling range, heating source hot water.Or the temperature difference of the cold water temperature difference, cooling range, heating source hot water is divided into four temperature difference sections, simultaneously generator, condenser, evaporimeter, absorber also all are divided into four.And can the temperature difference be made further multistage according to this principle and cut apart and more parts are cut apart.After the segmentation generator, condenser are arranged in the same cavity, evaporimeter, absorber are arranged in the same cavity, this generator, condenser, evaporimeter, absorber and solution heat exchanger, pump, valve, pipeline etc. are formed independently cold-producing medium and absorption liquid closed circuit, and whole device is combined by two or more this independently cold-producing mediums and absorption liquid working cycles loop; Wherein the generator with absorber, condenser and the hot water outlet position at the evaporimeter at cooling water inlet position, cooling water inlet position is combined in same independently cold-producing medium and the absorption liquid closed circuit; The evaporimeter at cooling water outlet position, the generator at the absorber at coolant outlet position, condenser and hot water inlet position are combined in same independently cold-producing medium and the absorption liquid closed circuit; Cold water, cooling water, hot-water heating system are with all the other generators, condenser, independent cooling agent that evaporimeter, absorber are formed and absorption liquid working cycles loop, be connected between above-mentioned two combinations, form the big combination in a plurality of independently refrigeration and absorption liquid working cycles loop.
For considering the simple and best segmentation of manufacturing cost and system, generally be divided into two-period form.Two-period form is like this combination: it is concentrated mutually to help one section low favorable factor of cold water temperature that absorber weak solution concentration is reduced high a section and cooling water temperature, be combined in the cavity, the condenser that will reduce the low-temperature cooling water section that pressure takes place combines in a cavity with the generator of hot water outlet.Above-mentioned two parts are combined into a cold-producing medium and the absorption liquid circulatory system.The favourable factor of this system effectively utilizes the low-temperature water heating thermal source during operation.And high one section of remaining cold water temperature low a section and cooling water temperature high a section and hot water temperature is combined in another cold-producing medium and the absorption liquid circulatory system, by another group generator, condenser, evaporimeter, absorber combination work.The high-temperature-hot-water thermal source has overcome other unfavorable factor that device is in operation again in another circulation.Guarantee the high efficiency of kind of refrigeration cycle and improved thermodynamic coefficient.
Compared with prior art, since the utility model with original single generator, condenser, evaporimeter, absorber all segmentation change two or more generators, condenser, evaporimeter, absorber into, and the favorable factor that will evaporate, absorb is further optimized, obtained routine techniques in the past the lower weak solution concentration and lower generation pressure that can't obtain, in generator, the temperature that comes to life of solution is further reduced, thereby heat source temperature can be even lower.Under identical hot water inlet temperature and cooling water outlet and inlet temperature, cold water out temperature condition, the hot water outlet temperature can be reduced by 18 ℃ than original, and thermodynamic coefficient COP can be improved effectively.
