Fig. 2 is the another embodiment of the invention structure principle chart.
The specific embodiment
The present invention is described further below in conjunction with accompanying drawing
Embodiment 1
Referring to Fig. 1, fresh air conditioner machine of the present invention comprise circulating pump 1, single-stage spray pump 3, condenser/evaporator 6, evaporator/condenser 8 and the branch formed by filler about two-layer uniform Pyatyi (I-V) solution heat regenerator 5.Each solution heat regenerator 5 of upper strata is sent into exhausting duct successively with after indoor air-return duct is connected in series.Each solution heat regenerator 5 of lower floor is sent into indoor air inlet duct successively with after fresh flue, place, chamber is connected in series.The bottom connection of the V of the lower floor level solution heat regenerator 5 of the import of circulating pump 1 and close outdoor fresh flue, the bottom connection of the upper strata V level solution heat regenerator 5 of the outlet of circulating pump 1 and close exhausting duct.The bottom of each solution heat regenerator 5 is connected in series the solution that makes bottom in each solution heat regenerator 5 successively by connecting leg and forms the reverse circulation opposite with the levels wind direction.The bottom of each solution heat regenerator 5 all joins with the import of corresponding single-stage spray pump 3.The import of the outlet of each single-stage spray pump 3 and set heat exchanger 2 is joined, and the shower 7 in the outlet of each heat exchanger 2 and the corresponding solution heat regenerator 5 joins.Wherein be connected in series described condenser/evaporator 6 between the shower 7 near the outlet of the V level single-stage spray pump 3 of exhausting duct and its solution heat regenerator 5.Be connected in series described evaporator/condenser 8 between the bottom near the import of the I level single-stage spray pump 3 of indoor air inlet duct and solution heat regenerator 5.Solution in described each solution heat regenerator 5 is the salting liquid that lithium bromide and lithium chloride mixed liquor form.
When using summer, the present invention mainly is divided into two parts, and the one, the full heat recovery section of utilizing solution to circulate, the 2nd, the kind of refrigeration cycle part of low capacity.Because the main body of new blower fan is divided into two-layer up and down, the upper strata is a return air channel, and lower floor is new wind passage.In the return air channel, from left to right be I, II, III, IV, the V level contact heat mass exchanger of the full heat regenerator 5 of solution successively, salting liquid in the wherein preceding level Four carries out the exchange of heat with the salting liquid of lower floor new wind passage by heat exchanger 2 under the driving of circulating pump 1.For the power of regeneration of salting liquid in the enhancing system, the heat exhaust of the condenser 6 of the salting liquid absorbent refrigeration system of V level.In the new wind passage of lower floor, be V, IV, III, II, the I level contact heat mass exchanger of solution heat regenerator 5 from right to left successively, the salting liquid in the back level Four respectively with the upper strata return air channel in IV, III, II, the salting liquid in the I level carry out exchange heat.In order to strengthen the effect of salting liquid dehumidifying and cooling, the salting liquid in the I level is cooled off by the evaporimeter 8 of refrigeration system.The flow direction of inter-stage salting liquid in new wind and the lower floor's passage, and the flow direction of inter-stage salting liquid all is opposite in return air and the upper strata passage.What therefore carry out in upper and lower two passages all is adverse current caloic exchange process.
The flow process of salting liquid is: systemic circulation pump 1 extracts salting liquid and sends in the solution heat regenerator 5 of upper strata V level from the groove of the V of lower floor level solution heat regenerator 5, effect by free surface, make upper strata passage salting liquid flow to left-hand I level by the right side from the V level, the I level of lower floor is got back in overflow afterwards, from left to right flows to the V of lower floor level in lower floor's passage then.Owing to adopt the mode of overflow, make flow between at different levels by the flow decision of circulating pump 1 and can keep constant.The mobile power that provides of salting liquid in each solution heat regenerator 5 is provided circulating pump 1, and the concentration of salt solution in each solution heat regenerator 5 of levels is different with temperature.In each grade solution heat regenerator 5 of upper and lower passage, extract salting liquid the salting liquid groove of single-stage spray pump 3 in this grade and enter heat exchanger 2 or evaporimeter 8, condenser 6, after the salting liquid heat exchange, shower 7 spray from solution heat regenerator at the corresponding levels 5 tops contact with processed new wind or return air in filler and carries out heat and wet and exchange.Single-stage spray pump 3 provides interior salting liquid circulation at the corresponding levels to spray required pressure head.What realize in lower floor's passage is dehumidification process, because the surface vapor pressure of salting liquid is lower than the partial pressure of steam in the new wind, realizes the transition process of water in air steam to salting liquid, and the humidity of air reduces, and the concentration of salting liquid descends.What realize in the passage of upper strata is the regenerative process of salting liquid, and moisture transmits in return air in the salting liquid, makes the concentration of salting liquid increase, and return air is discharged after by humidification simultaneously.
When using in the winter time, refrigeration can not moved, and perhaps adopts the mutual conversion between cross valve realization evaporimeter and the condenser, and condenser/evaporator 6 and evaporator/condenser 8 transposings are used.Fully reclaim the heat and the moisture of air draft, realize the warming and humidifying process of new wind.
Embodiment 2
Referring to Fig. 2, present embodiment part same as the previously described embodiments repeats no more.Different is that the heat exchanger in the foregoing description 2 is removed, all join and form the bottom that levels differs lower floor's solution heat regenerator 5 of one-level with the import of the set single-stage spray pump 3 of the corresponding levels, the outlet of each single-stage spray pump 3 is joined with the shower 7 that levels differs in each solution heat regenerator 5 of upper strata of one-level successively, and the bottom of each solution heat regenerator 5 of upper strata joins with the shower 7 that levels differs in each solution heat regenerator 5 of lower floor of one-level successively.The use of present embodiment is also identical with the use of the foregoing description, only is the heat exchange link that has lacked between each solution heat regenerator 5 of levels.The characteristics of present embodiment are that the structure structure is simpler, but operational effect is poor slightly.
What deserves to be explained is that in addition according to above-mentioned embodiment, the multi-stage solution heat regenerator of being made up of filler 5 is not limited to Pyatyi, can be below the Pyatyi or more than the Pyatyi.Described condenser/evaporator 6, evaporator/condenser 8 can adopt the heat-exchange device of other form to replace.Technical scheme such as a class all belongs to protection scope of the present invention.
