As shown in Figure 1, supply line 28 provides drier from outdoor unit 12 to each indoor unit 14,16,18; Similarly, the line of return 30 receives drier and is sent back to outdoor unit 12 from each indoor unit 14,16,18.Although three indoor units are illustrated in Fig. 1, other embodiments can comprise the indoor unit greater or less than three.As used herein, word " indoor " and " building " be often referred to limit at least a portion enclosure space and by it from the separated any structure of outdoor environment around.For example, " building " can be tent or other interim, local enclosed construction.
Fig. 2 shows schematically illustrating of the outdoor unit 12 shown in Fig. 1.This outdoor unit 12 holds the first process chamber 32, and in this first process chamber, drier 34 is transferred to indoor unit 14,16,18 and transfers out from indoor unit.Any desiccant material that can produce desired effects can be used, and comprises the liquid of following form: neat liquid, solution, the aqueous solution, mixture and their combination.Lithium chloride (LiCl) and calcium chloride (CaCl2) are typical liquid desiccant solutions, but other liquid driers also can be used.Outdoor unit 12 also holds regenerator 35, and it comprises regeneration chamber 36, and drier 34 can be regenerated in this regenerates chamber.In the embodiment shown in Fig. 2, drier 34 is by hole transmission between the first process chamber 32 and regeneration chamber 36, and this hole can be hole 38.In other embodiments, transmission can be controlled by floating and pump machanism or any other method or the system of effectively transmitting as required drier.More specifically, drier 34 is transmission between the first for the treatment of pond 42 and regenerator pond 43, regenerator pond 43 is separated portion 39 separates, and this separating part has the hole 38 being arranged at wherein, and hole 38 allows drier 34 to spread between 42He pond, pond 43 based on concentration gradient.As below more detailed description, each of indoor unit comprises the second portion for the treatment of pond, and the first of each for the treatment of pond second portion and treatment pond 42 optionally fluid is communicated with.
As shown in Figure 2, the first chamber 32 receives from indoor unit 14,16,18 drier 34, as shown in dotted line 40.In this embodiment, drier 34 is maintained at the first of the treatment pond 42 at the place, bottom that is arranged in the first process chamber 32 that is contained in outdoor unit 12.First processes pump 44 is used to through over-heat-exchanger 46, pump drier 34 from the first for the treatment of pond 42, and then drier 34 is pumped into indoor unit, as shown in dotted line 48.In the embodiment shown in Fig. 2, heat exchanger 46 is evaporimeters, and this evaporimeter is a part for the refrigeration system based on steam compression cycle, and this refrigeration system comprises compressor 50, the first condenser 52, the second condensers 54, and thermal expansion valve 55.In other embodiments, drier can be cooled and be heated by other source, as water cooling pond, solar source etc.By-passing valve 57 allows some cooling drier 34 to be reintroduced in the first process chamber 32, as shown in dotted line 59.Effectively make pond 42 keep cooling drier the adding of cooling drier 34 of getting back to the first for the treatment of pond 42, and as cooling liquid storage unit, when one or more indoor units 14,16,18 need when cooling, cooling liquid can be from wherein taking out.
Steam compression system shown in Fig. 2 can be used any fluid, and as cold-producing medium, this fluid can make this steam compression system transmit optionally heating and cooling drier 34 by the heat transmission to cold-producing medium with from the heat of cold-producing medium effectively.Fig. 2 shows the outdoor unit 12 under the first operational mode, and this first operational mode can be effectively used in warm, moist environment.Under this pattern, as shown in dotted line 56, heat is transferred to drier 34 from the first condenser 52.Drier 34 is reproduced pump 58 and pumps through condenser 52.After leaving condenser 52, drier 34 is sprayed on medium 60, and medium 60 can comprise one or more easy penetration materials, and it allows drier 34 to flow through them.The second condenser 54 can have associated fan (not shown), for being transferred to the surrounding environment of outdoor unit 12 outsides from some heats of steam compression system, thus further cooling refrigeration agent before the expansion stage of circulation.Although compressor 50 and condenser 52 are illustrated in regeneration chamber 36, in other embodiments, they can be positioned at the outside in regeneration chamber, and complete in another part of first module, or completely outside in first module.These assemblies are processed additional heat are provided for regeneration in regeneration chamber 36, thereby contribute to deviate from more water from drier 34.
As mentioned above, drier 34 receives the heat of automatic heat-exchanger 52, and this processing contributes to by displacing some moisture drier 34 of regenerating, and these moisture are to be drawn from the air their interior spaces 20,22,24 separately by indoor unit 14,16,18.Except displacing some moistures with heating from drier 34, outdoor unit 12 is also used air-flow further to remove moisture.As shown in Figure 2, the first air-flow 62 enters the second chamber 36 from outdoor environment around through entrance 64.Air-flow 62 is driven in by the fan 66 that drives air to enter the second chamber 36, passes through drier bearing medium 60, and discharges through outlet 68, and at outlet 68 place's air-flows 62, being illustrated as 62 is to represent carrying moisture when it leaves the second chamber 36.Because hole 38 is arranged under the horizontal level of drier in pond 42,43, so the first process chamber 32 is effectively sealed, and there is not any contact with air-flow 62.
Fig. 3 A and 3B show respectively front view and the side view of the indoor unit 14 shown in Fig. 1.As shown in Figure 3A, the drier 34 that valve 70 receives from outdoor unit 12, as shown in dotted line 72, and especially, it receives the drier 34 from the first for the treatment of pond 42.Valve 70 is connected to floating system 74, and this floating system 74 has shown at the horizontal level of drier 34 of second portion for the treatment of pond 76 that is arranged in the bottom of the second process chamber 77 that is contained in indoor unit 14.Thereby in the embodiment with describing shown here, the processing side of system 10 is the slits between outdoor unit 12 and indoor unit 14,16,18.A part that makes to process side has reduced significantly the complexity that the matter and energy about balance drier 34 between dilution process side drier and more concentrated regeneration side drier transmits in this unit of the reproducing unit of containment 10.In addition, the another part that makes to process side is contained in and in indoor unit, allows the independent adjusting of controlling the surrounding air in different spaces.
Except receiving the information about the horizontal level of drier 34, valve 70 also receives the information from temperature sensor 78, and this temperature sensor 78 is measured the temperature of the drier 34 in pond 76.Valve 70 can be the electronically actuated magnetic valve of for example threeway, and the specific input of its response, comprises the input from floating system 74 and temperature sensor 78.The control of valve 70 can be a part for large control system, this large control system also coordinate and control chart 2 shown in the operation of various assemblies of outdoor unit.This control system can comprise the one or more operation programs that allow each indoor unit 14,16,18 to be controlled independently of one another, thus provide they separately in room 20,22,24 the independent of environment control.
When as by floating system 74 shown in drier 34 horizontal level and/or while arriving valve 70 by the input of the temperature of the drier 34 shown in temperature sensor 78, show that this valve 70 should be unlocked, drier 34 from outdoor unit 12 is supplied to indoor unit 14, as shown in dotted line 80.In warm, moist environment, the drier 34 that enters indoor unit 14 from outdoor unit 12 will be cooled and be relatively dried-, by water, do not diluted.As below statement, this makes surrounding air in room 20 dehumidified and be cooled to the level of expectation.
Fig. 3 B shows the side view of indoor unit 14, and has shown how air-flow passes unit 14 and how by unit 14, to be processed.First, the second air-flow 86 enters indoor unit 14 from indoor environment around; Once in inside, when air-flow 86 crosses medium 84, it is introduced into drier 34 and contacts, as shown in arrow 88.Air stream is controlled by fan 90, and after air-flow 86 is cooled and dehumidifies, this fan 90 is discharged the second air-flow 86 to get back in surrounding environment, now by mark 86 ' expression.When the drier 34 at indoor unit 14 is collected moisture constantly, the horizontal level of the drier 34 in pond 76 will promote.In addition, the temperature of the drier in the second portion for the treatment of pond 76 34 will raise.
At certain a bit, some drier 34 will be pumped back to outdoor unit, as shown in the dotted line 94 shown in Fig. 3 A.Drier 34 in indoor unit 14 can be supplied with and be flow to outdoor unit by gravity, or can be pumped.Thereby the equipment 96 schematically illustrating in Fig. 3 A can be valve for example, when drier 34 reaches certain level position, this valve allows drier 34 automatically to flow out indoor unit 14.Selectively, equipment 96 can be electronically actuated valve, and valve 70 as described above.In this case, when specific input signal (temperature of drier 34 and/or horizontal level in as pond 76) occurs, this valve 96 can be unlocked.When turning back to outdoor unit 12, drier 34 is regenerated according to said process.
Because indoor unit 14,16,18 is independently controlled, and as the space may with different requirements, therefore, in some unit, floating system 74 can be activated continually, and in other unit, it is but activated rarely simultaneously.In at least some cases, before floating system 74 activated, air-flow 86,86 ' may be through specific indoor unit recirculation many times.This to be the processing side that makes the air handling system based on drier separate between outdoor unit and independent indoor unit other advantage-, concentration that needn't be based on drier in indoor unit pond from the transmission of the drier of indoor unit (although its can); On the contrary, it can be based on temperature or the volume of the liquid based in tank interior strictly.By this way, the more complicated control of the concentration of balance drier is fully processed in being independent of the outdoor unit of indoor unit.
Above-mentioned air conditioning moves with the surrounding air in cooling and dehumidifying room under the first operational mode.Yet system 10 can also regulate air to make it have reverse effect-, system 10 can be moved with the surrounding air in heating and humidification space under the second operational mode.This kind of mode that can be implemented is to provide the additional water that directly arrives outdoor unit 12.This is represented by dotted line 98 in Fig. 4, dotted line 98 shows directly the adding of water of the first for the treatment of pond, the first of this treatment pond in Fig. 4 by 42 ' indicate, apostrophe (') represents the assembly similar to other accompanying drawings of assembly that are illustrated in the system 10 under the first operational mode.Regenerator 35 ' be closed, and particularly pump 58 ' and fan 66 ' not operation, therefore, to the increase that adds the dilution that has directly caused pond 42 ' middle drier 34 of the water in outdoor unit 12, and regenerator pond 43 ' in, water can not evaporate from drier.
Except add water in drier 34, can also increase heat to drier 34, so that drier warm, dilution can be supplied to indoor unit 14,16,18.Heat can increase by any effective method, to realize the result of expectation, as inverted running steam compression system.As shown in Figure 4, compressor 50 ' existing by refrigerated medium pump to the first condenser 52 ', this first condenser 52 ' be used to by the first processing pump 44 ' from treatment pond 42 ' First wheel cylinder to drier 34 heat-shifts indoor unit 14,16,18.Under this second operational mode, it can be considered to " pattern in winter " in some cases, cold-producing medium by alternatively through second condenser 54 ' pumping, although and not shown in Figure 4, drier 34 can be crossed condenser 52 ' and 54 ' to obtain extra heat by pump.
Selectable, system 10 can be provided with solar collector, and it can, by physically attached or operation at a distance, think that system 10 provides heat and/or electricity.When this processes while being carried out, drier 34 warm, dilution cross medium 84 be situated between referring to Fig. 3 A figure this medium place moisture and heat by the second air-flow 86 collect-referring to Fig. 3 B figure before surrounding environment is got back in this second air-flow discharge.
Although illustrative embodiments is described in the above, this can not be regarded as these embodiments and describe all possibility forms of the present invention.On the contrary, the word using in description is descriptive word rather than restrictive word, and is appreciated that and can makes various changes and not depart from spirit and scope of the invention.In addition, the feature of the different embodiments of implementing can be combined to form other embodiment of the present invention.
