In, it is set to specific gravity=1.0 (g/cm identical with water3), specific heat=4.187kJ/ (kgk) and calculate.
(cooling and dehumidifying)
Firstly, in the case where the cooling and dehumidifying operating that summer etc. keeps outside air cooling and dehumidifies, as shown in figure 4, adjusting
The cooling coil 21 in warm portion 20 keeps outside air cooling ([1] point → [2] point), and damping portion 23 carries out the dehumidifying ([2] of outside air
Point → [4] point).In recasting portion 3, the heating ([5] point → [6] point) of outside air is carried out using heating part 31, utilizes concentration
The concentration ([6] point → [7] point) of the progress of portion 32 moisture adsorption and releasing solution.Concentrated moisture adsorption and releasing solution is supplied to damping portion 23 and uses
In dehumidifying, and it is returned to recasting portion 3 ([A] point → [B] point).
Using the air line chart of Fig. 5, illustrate the result of the effect when cooling and dehumidifying operating of simulated air processing system.If
Definite value (set point, SP) is set as 22 DEG C of dry-bulb temperature, relative humidity 40%, absolute humidity 6.6g/kg', specific enthalpy 38.8kJ/
Kg', 7.8 DEG C of dew-point temperature, the outside air amount captured to gas supply path 100 is set to 1kg'/h (=0.84m3/ h) and count
It calculates.
[1] of the air line chart of Fig. 5~" 7 " point corresponds to [1]~[7] point of Fig. 4.That is, [1] point is air-treatment portion 2
Outside air inlet, [2] point be cooling coil 21 the outlet of outlet=temperature adjustment portion 20, [4] point be damping portion 23 outlet.
[4] the case where point is no heat exchanger 82, [4'] point is to carry out cooling situation using heat exchanger 82.[5] point is recasting portion 3
Outside air inlet, [6] point is the point for pass through heating part 31, and it is the point for having passed through concentrating part 32 that [7], which are put,.[6], [7] point
The case where being no heat exchanger 82, [6'], [7'] point are that cooling situation is carried out using heat exchanger 82.It is recorded on each point
Number be (dry-bulb temperature [DEG C]/relative humidity [%]/absolute humidity [g/kg']/specific enthalpy [kJ/kg'], dew-point temperature
[℃])。
Outside air ([1] point: 33/62/19.8/ of high temperature and humidity is imported from outside air mouth 101 to gas supply path 100
83.9/24.7).Outside air is cooled down by the cooling coil 21 in temperature adjustment portion 20, thus become defined specific enthalpy ([2] point:
14.3/95/9.7/38.8/13.6).Then, outside air (puts phase with [2] after the heating coil 22 in temperature adjustment portion 20
Together), by damping portion 23 dehumidify and become SP ([4] point: 22/40/6.6/38.8/7.8), and from air supply opening 102 supply to
Conditioned space R.
As the 1kg'(=0.84m for the process object for becoming [1]3) outside air when elapsing to [2], for passing through cooling
Coil 21 and be set as the cooling heat comprising dehumidifying of defined specific enthalpy (38.8kJ/kg') and its moisture removal (1) and be used for
The moisture removal (2) for the humidity value for being set as being set by damping portion 23 is as described below.
Cooling heat: 83.9-38.8=45.1kJ/kg'
Moisture removal (1): 19.8-9.7=10.1g/kg'
Moisture removal (2): 9.7-6.6=3.1g/kg'
When 12.5g/1000g'=will be set as relative to outside air amount as the drainage of the LiCl of moisture adsorption and releasing solution
0.0125 (L/G), when concentration is set as 40wt%, the concentration variation of LiCl is as described below.
LiCl 5.0g+H2O 7.5g=12.5g (40wt%)
→LiCl 5.0g+H2O 10.6g=15.6g (32wt%)
When the drainage of LiCl is set as 0.0125 (L/G), when concentration is set as 35wt%, the concentration variation of LiCl is as follows
It is described.
LiCl 4.4g+H2O 8.1g=12.5g (35wt%)
→LiCl 4.4g+H2O 11.2g=15.6g (28wt%)
Furthermore when increasing drainage, the concentration of LiCl, which changes, to be reduced.For example, when being set as L/G=25g/1000=
When 0.025, variation when LiCl concentration is 35wt% is as described below.
LiCl 8.8g+H2O 16.2g=25.0g (35wt%)
→LiCl 8.8g+H2O 19.3g=28.1g (31wt%)
As described above, drainage is more, even if reducing LiCl concentration, it is also more able to maintain that defined moisture removal.It reduces
LiCl concentration can reduce the heating temperature in recasting portion 3, so selecting upper advantage more in energy efficiency and heating source.It is another
Aspect, when humidification in winter, the humidification waters such as common tap water without lithium chloride be set to L/G=0.02 or so hereinafter,
So in moisture adsorption and releasing solution, that is, LiCl solution of present embodiment, it is generally desirable to which L/G is also at most set as 0.03 or less degree.And
And the numerical value for being equivalent to the saturation efficiency of gasifying type humidification also changes because of LiCl concentration, so by outside air and gas
η=0.7 or more of the saturation efficiency that the gas liquid interfacial area of change formula humidifier determines preferably common tap water.
Furthermore it is such as put compared with [6'] point from [6], [7] point utilizes heat exchanger 82 it is found that working as compared with [7'] point
When being cooled down, it can not elevate the temperature and dehumidify, can reduce the heating temperature in recasting portion 3.
(heating and dehumidification)
Secondly, the case where heating and dehumidification that explanation heats outside air and dehumidifies operates.So-called needs heating removes
The case where wet operating, for example, referring to as shown in [1'] of Fig. 5, the specific enthalpy of outside air is lower than SP, and absolute humidity is higher than the feelings of SP
Condition.As shown in figure 4, outside air is heated ([1'] point → [3] point) in temperature adjustment portion 20, damping portion 23 carries out outside air
It dehumidifies ([3] point → [4] point).In recasting portion 3, the heating ([5] point → [6] point) of outside air is carried out using heating part 31,
The concentration ([6] point → [7] point) of moisture adsorption and releasing solution is carried out using concentrating part 32.The moisture adsorption and releasing for having adjusted concentration by concentration are molten
Liquid is supplied to damping portion 23 and is used to dehumidify, and is returned to recasting portion 3 ([A] point → [B] point).
Using the air line chart of Fig. 5, illustrate the result of the effect when heating and dehumidification operating of simulated air processing system.If
Definite value (SP) be when the cooling and dehumidifying in the same manner as, be set as 22 DEG C of dry-bulb temperature, relative humidity 40%, absolute humidity 6.6g/
Kg', specific enthalpy 38.8kJ/kg', 7.8 DEG C of dew-point temperature, capture to gas supply path 100 outside air amount be set to 1kg'/h (=
0.84m3/ h) and calculate.
[1'] of the air line chart of Fig. 5, [3], [4] correspond to [1], [3], [4] point of Fig. 4.Documented by each point
Number is (dry-bulb temperature [DEG C]/relative humidity [%]/absolute humidity [g/kg']/specific enthalpy [kJ/kg'], dew-point temperature [DEG C]).
How wet outside air ([1'] point: 14.0/80/ of low temperature is imported from outside air mouth 101 to gas supply path 100
8.0/34.2/10.6).Outside air is heated by passing through the heating coil 22 in temperature adjustment portion 20, to become defined specific enthalpy
([3] point: 18.4/60.8/8.0/38.8/10.7), and dehumidified ([4] point: 22/40/6.6/38.8/ by damping portion 23
7.8), and from the supply of air supply opening 102 to conditioned space R.
The humid control of object handles air is control performed in the following way: by the resulting value of humidity sensor H
Higher than setting value humidity when increase drainage, by humidity sensor H it is resulting value be lower than setting value humidity when reduce drip
The amount of falling.
Furthermore in dehumidifying operating, temperature adjustment portion 20 is located at upstream side, and damping portion 23 is located at downstream side, so air
The setting of state and actual variation are to become to set humidity after becoming defined specific enthalpy.About the change to setting humidity
Change, due to the heat of solution of the outside air moisture of moisture adsorption and releasing solution, and along with temperature change slightly different in isenthalp,
But finally in a manner of converging to setting humidity, cooling is carried out by temperature adjustment portion 20, is heated.
[humidification operating]
When mode selection part 93 has selected humidifying mode, air treatment system carries out humidification operating.The operation is shown
In Fig. 6 and Fig. 7.Fig. 7 indicates air-treatment portion 2, recasting portion 3.The flowing of outside air is that gas supply is indicated with hollow block arrow.
The flowing of moisture adsorption and releasing solution is indicated with heavy line, and the flowing of hot water is indicated with thick dashed line, and the flowing of dilution water is with two o'clock
Chain line indicates.In figure 6 and figure 7, it illustrates and the state of cold water has been supplied to cooling coil 21 and heating coil 22 is supplied
The state of hot water, but in temperature adjustment portion 20, select which state and keep outside air cooling or heating, be to pass through switching valve
21c, valve 22c opening and closing and carry out.
(warming and humidifying)
Firstly, in winter etc., in the case where being operated to the warming and humidifying that outside air is heated and is humidified, such as Fig. 7 institute
Show, outside air is heated ([1] point → [3] point) in temperature adjustment portion 20, and damping portion 23 carries out humidification ([3] point of outside air
→ [4] point).It is dense to moisture adsorption and releasing solution to the heating of outside air, concentrating part 32 without heating part 31 in recasting portion 3
Contracting, and only it is diluted dilution of the portion 321 to moisture adsorption and releasing solution.It is supplied to by the moisture adsorption and releasing solution that dilution adjusts concentration
It is used to humidify to damping portion 23, and is returned to recasting portion 3 ([A] point → [B] point).
Using the air line chart of Fig. 8, illustrate the result of the effect when warming and humidifying operating of simulated air processing system.If
Definite value (SP) is set to 22 DEG C of dry-bulb temperature, relative humidity 40%, absolute humidity 6.6g/kg', specific enthalpy 38.8kJ/kg', dew point
7.8 DEG C of temperature, the outside air amount captured to gas supply path 100 is set to 1kg'/h (=0.84m3/ h) and calculate.
[1] of the air line chart of Fig. 8, [3], [4] point correspond to [1], [3], [4] point of Fig. 7.That is, [1] point is external empty

Outside air ([1] point: 0/34/1.3/ of low temperature and low humidity is imported from outside air mouth 101 to gas supply path 100
3.2/-12.5).Outside air is heated by the heating coil 22 in temperature adjustment portion 20, thus become defined specific enthalpy ([3] point:
35.3/3.7/1.3/38.8/-12.5).Then, ([4] point: 22/40/6.6/38.8/7.8) is humidified by damping portion 23, and
From the supply of air supply opening 102 to conditioned space R.
As the 1kg'(=0.84m for the process object for becoming [1]3) outside air when elapsing to [3], be used for heating coil
The 22 following institutes of humidification amount for being set as the heating heat of defined specific enthalpy (38.8kJ/kg') and being set as setting value for damping portion 23
It states.
Heat heat: 38.8-3.2=35.6kJ/kg'
Humidification amount: 6.6-1.3=5.3g/kg'
In the system humidified using drip-type gasifying type, in order to obtain it is described under the conditions of humidification amount, can be saturation
The gasifying type humidification membrane of efficiency eta=63% or so.Also, the drainage of moisture adsorption and releasing solution is usually set to humidify required amount
Twice or so, to prevent the precipitation portion in dust or water.In the example, 5.3g/kg' × 2=10.6g/kg' is there was only water
The drainage divided.It is following drainage as moisture adsorption and releasing solution when LiCl solution is set as concentration 15wt%:
10.6 ÷ 0.85=12.5g/kg (LiCl 15%=1.9g, H2O 85%=10.6g)
12.5g/1000g'=0.0125 (L/G).
At this moment the concentration variation of LiCl is as described below.
LiCl 1.9g+H2O 10.6g=12.5g (15wt%)
→LiCl 1.9g+H2O 5.3g=7.2g (26wt%)
(cooling humidification)
Secondly, the case where explanation keeps outside air cooling and the cooling humidification operating of humidification.It is so-called that cooling is needed to humidify
Situation, for example, refer to as shown in [1'] of Fig. 8, the case where specific enthalpy of outside air is higher than SP, and absolute humidity is lower than SP.Such as Fig. 7
